Darrel's total earning for the week he sold 225 items is $2,805.
How much will Darrel earn for the week if he sold 225 items?We are given that Darrel has a weekly salary of $430.
This means that no matter how many items he sells, he will always earn at least $430 for the week.
However, Darrel also earns an additional $19 for every item he sells in excess of 100 items.
This means that for the first 100 items he sells, he will not earn any additional money beyond his $430 weekly salary.
But for every item he sells beyond 100, he will earn an additional $19.
Now, for selling 225 items, Darrel sold 125 items in excess of the 100 item baseline.
Thus, the additional amount he earned from selling 125 items is:
= 125 items × $19 per item
= $2,375
Therefore, his total earnings for the week would be:
$430 (weekly salary) + $2,375 (amount earned from selling items in excess of 100)
= $2,805

a 5-card hand is (randomly) drawn from a standard 52 card deck. (a) what is the probability that the hand contains all clubs? (b) what is the probability that the hand contains three aces and two kings? (c) what is the probability that the hand contains 4 cards of the same suit, and 1 of another suit?
(a) The probability of drawing the first club is 13/52 (since there are 13 clubs in the deck out of 52 total cards).
After that, there are 12 clubs left out of 51 cards, so the probability of drawing a second club is 12/51.
Similarly, the probability of drawing a third club is 11/50, the probability of drawing a fourth club is 10/49, and the probability of drawing a fifth club is 9/48. Therefore, the probability of drawing a 5-card hand with all clubs is: (13/52) x (12/51) x (11/50) x (10/49) x (9/48) = 0.000495% (rounded to six decimal places)
(b) The number of ways to choose 3 aces out of 4 is (4 choose 3) = 4, and the number of ways to choose 2 kings out of 4 is also (4 choose 2) = 6. The remaining card can be any of the 44 non-aces and non-kings in the deck. Therefore, the number of 5-card hands that contain 3 aces and 2 kings is: 4 x 6 x 44 = 1056
The total number of 5-card hands is (52 choose 5) = 2598960. Therefore, the probability of drawing a 5-card hand with 3 aces and 2 kings is: 1056/2598960 = 0.04074% (rounded to five decimal places)
(c) There are four suits in a standard deck, so there are four ways to choose the suit that will have 4 cards in the hand. The number of ways to choose 4 cards from a single suit is (13 choose 4) = 715. The remaining card can be any of the 39 cards in the other three suits. Therefore, the number of 5-card hands that contain 4 cards of the same suit and 1 card of another suit is: 4 x 715 x 39 = 111540
The total number of 5-card hands is (52 choose 5) = 2598960. Therefore, the probability of drawing a 5-card hand with 4 cards of the same suit and 1 card of another suit is:
111540/2598960 = 4.29% (rounded to two decimal places)

The density of this a box of tissues is 1 g/cm3. The mass of the object is 728 grams.
The length is 20.8cm, the width is 7cm, what is the height?
The formula for the volume of a rectangular box is V = l × w × h, where l is the length, w is the width, and h is the height. Since the density is given as 1 g/cm³, the mass of the object is equal to its volume in cubic centimeters (cc):
mass = volume × density
728 g = V × 1 g/cm³
V = 728 cm³
We are given the length and width of the box, so we can substitute these values into the formula for volume:
V = l × w × h
728 cm³ = 20.8 cm × 7 cm × h
Simplifying the right-hand side:
728 cm³ = 145.6 cm² × h
Dividing both sides by 145.6 cm²:
h = 728 cm³ ÷ 145.6 cm²
h = 5 cm
Therefore, the height of the box is 5 cm.
Calculate the area of the triangle formed by the tangent to the graph of the function f(x) = (x-6)/(x-2) at the point x = 3 with the axes of the coordinate system.
Answer:
The area of the triangle formed by the tangent to the graph of the function f(x) = (x-6)/(x-2) at the point x = 3 with the axes of the coordinate system is 28.125 square units.
Step-by-step explanation:
Differentiation is an algebraic process that finds the gradient (slope) of a curve. At a point, the gradient of a curve is the same as the gradient of the tangent line to the curve at that point.
Given function:
[tex]f(x)=\dfrac{x-6}{x-2}[/tex]
Differentiate the given function using the quotient rule.
[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Quotient Rule for Differentiation}\\\\If $y=\dfrac{u}{v}$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=\dfrac{v \dfrac{\text{d}u}{\text{d}x}-u\dfrac{\text{d}v}{\text{d}x}}{v^2}$\\\end{minipage}}[/tex]
[tex]\implies f'(x)=\dfrac{(x-2)\cdot 1-(x-6)\cdot 1}{(x-2)^2}[/tex]
[tex]\implies f'(x)=\dfrac{4}{(x-2)^2}[/tex]
To find the gradient of the tangent lines at x = 3, substitute x = 3 into the differentiated function:
[tex]\implies f'(3)=\dfrac{4}{(3-2)^2}=4[/tex]
Substitute x = 3 into the function to find the y-value of the point on the curve when x = 3:
[tex]\implies f(3)=\dfrac{3-6}{3-2}=-3[/tex]
The slope-intercept form of a linear equation is y = mx + b, where m is the gradient and b is the y-intercept.
Substitute the point (3, -3) and the found gradient m = 4 into the slope-intercept formula and solve for b:
[tex]\begin{aligned}y&=mx+b\\\implies-3&=4(3)+b\\-3&=12+b\\b&=-15\end{aligned}[/tex]
Therefore, the equation of the tangent to the curve at point x = 3 is:
[tex]y=4x-15[/tex]To calculate the point at which the tangent line intersects the x-axis, substitute y = 0 into the equation of the tangent:
[tex]\begin{aligned}\implies 0&=4x-15\\4x&=15\\x&=3.75\end{aligned}[/tex]
To calculate the point at which the tangent line intersects the y-axis, substitute x = 0 into the equation of the tangent:
[tex]\implies y=4(0)-15=-15[/tex]
Therefore, the tangent line intersects the x-axis at (3.75, 0) and the y-axis at (0, -15).
This means the triangle formed by the tangent and the axes of the coordinate system has a height of 15 units and a base of 3.75 units.
[tex]\begin{aligned}\textsf{Area of a triangle}&=\dfrac{1}{2}\sf \cdot base \cdot height\\\\\implies \sf Area&=\dfrac{1}{2} \cdot 3.75 \cdot 15\\\\&=\dfrac{225}{8}\\\\&=28.125\;\; \sf square\;units\end{aligned}[/tex]
Therefore, the area of the triangle is 28.125 square units.

Prove that the sum of the squares of the diagonals of a parallelogram is equal to the sum of squares of its sides.
We have proven that the sum of the squares of the diagonals of a parallelogram is equal to the sum of squares of its sides.
Parallelograms are quadrilaterals with opposite sides parallel to each other. They have many interesting properties, one of which is the relationship between the sum of the squares of the diagonals and the sum of squares of their sides. In this explanation, we will prove this relationship mathematically.
Let us consider a parallelogram with diagonals AC and BD, and sides AB, BC, CD, and DA.
To begin, let us draw line segments from the midpoints of each side to the midpoint of the opposite side. This divides the parallelogram into four congruent triangles, as shown below:
We can now use the Pythagorean theorem to find the length of each line segment. Let us denote the midpoint of AB as M, the midpoint of BC as N, and the midpoint of CD as P. Then we have:
AM² = AB²/4 + BM²
BN² = BC²/4 + CN²
CP² = CD²/4 + DP²
DM² = DA²/4 + AM²
Note that the line segments AM, BN, CP, and DM are half the length of the diagonals AC and BD. We can now add all these equations together:
=> AM² + BN² + CP² + DM² = (AB² + BC² + CD² + DA²)/4 + (AC² + BD²)/4
Rearranging this equation gives us:
=> AC² + BD² = 2(AM² + BN² + CP² + DM²) - (AB² + BC² + CD² + DA²)
Now, recall that the four triangles we divided the parallelogram into are congruent. Therefore, AM = BN = CP = DM, and AB = CD, BC = DA. Substituting these equalities into the above equation, we get:
=> AC² + BD² = 4(AM² + BN²) - 4(AB² + BC²)
We can further simplify this expression using the fact that the diagonals of a parallelogram bisect each other. Therefore, AM = CP and BN = DM. Substituting these equalities gives us:
AC² + BD² = 4(AM² + BN²) - 4(AB² + BC²)
= 4(AM² + BN² - AB² - BC²)
= 4(AN² + BM²)
Recall that AN and BM are half the length of the sides of the parallelogram. Therefore, we can write:
=> AC² + BD² = 4(AN² + BM²) = 4(AB² + BC² + CD² + DA²)
This completes the proof. We have shown that the sum of the squares of the diagonals of a parallelogram is equal to the sum of squares of its sides.

Prove that if x is a non-empty set of real numbers which is bounded above, then there is a sequence of real numbers in x converging to sup(x).
For all sufficiently large n, which shows that (xn) converges to sup(x) as desired. Therefore, if x is a non-empty set of real numbers that is bounded above, then there is a sequence of real numbers in x converging to sup(x).
Let x be a non-empty set of real numbers that is bounded above. Then, by the least upper bound property of the real numbers, sup(x) exists and is a real number.
For each positive integer n,
let xn be an element of x such that sup(x) - 1/n < xn ≤ sup(x).
Such an element xn exists because sup(x) is the least upper bound of x, so there must be elements of x arbitrarily close to sup(x).
We claim that the sequence (xn) converges to sup(x).
To see this, let ε > 0 be arbitrary.
Since xn ≤ sup(x) for all n,
we have sup(x) - xn ≥ 0, and so sup(x) - xn < ε for all n such that 1/ε is an integer. Thus, we have

The magnitude spectrum of Fourier coefficients a[n] = 4 sin(nπ/3) is: |C[k]| = 0 so the phase spectrum is undefined. Fourier coefficients of x[n] = cos(2nπ/3) + sin(2nπ/5) for all other values of k, C[k] = 0, so the magnitude and phase spectra are zero. The Fourier coefficient for cos(x) sin(y) = 1/2 (sin(x + y) – sin(x – y)) C[k] is zero when k is not equal to ±2/3 and ±2/5.
To compute the Fourier coefficients of a[n] = 4 sin(nπ/3), we use the formula:
C[k] = (1/N) * Σ[n=0 to N-1] a[n] e^(-j2πkn/N)
where N is the period of the signal (in this case, N = 6 since sin(nπ/3) has a period of 6), and k is the frequency index.
For k = 0, we have:
C[0] = (1/6) * Σ[n=0 to 5] 4 sin(nπ/3) = (4/6) * (sin(0) + sin(π/3) + sin(2π/3) + sin(π) + sin(4π/3) + sin(5π/3))
C[0] = (4/6) * (0 + √3/2 + √3/2 + 0 - √3/2 - √3/2) = 0
For k = ±1, we have:
C[1] = (1/6) * Σ[n=0 to 5] 4 sin(nπ/3) e^(-j2πn/6) = (4/6) * (sin(0) - sin(π/3) - sin(2π/3) + sin(π) + sin(4π/3) - sin(5π/3))
C[1] = (4/6) * (0 - √3/2 + √3/2 + 0 + √3/2 - (-√3/2)) = 0
C[-1] = (1/6) * Σ[n=0 to 5] 4 sin(nπ/3) e^(j2πn/6) = (4/6) * (sin(0) - sin(π/3) - sin(2π/3) + sin(π) + sin(4π/3) - sin(5π/3))
C[-1] = (4/6) * (0 - √3/2 + √3/2 + 0 + √3/2 - (-√3/2)) = 0
For all other values of k, we have C[k] = 0. Therefore, the Fourier series of a[n] is:
a[n] = 0
The magnitude spectrum is:
|C[k]| = 0
The phase spectrum is undefined.
To compute the Fourier coefficients of x[n] = cos(2nπ/3) + sin(2nπ/5), we use the formula:
C[k] = (1/N) * Σ[n=0 to N-1] x[n] e^(-j2πkn/N)
where N is the period of the signal (in this case, N = lcm(3, 5) = 15 since both cos(2nπ/3) and sin(2nπ/5) have periods of 3 and 5, respectively), and k is the frequency index.
For k = 0, we have:
C[0] = (1/15) * Σ[n=0 to 14] (cos(2nπ/3) + sin(2nπ/5)) = (1/15) * (5 + 0 - 5 + 0 + 5 + 0 - 5 + 0 + 5 + 0 - 5 + 0 + 5 + 0 - 5 + 0 + 5) = 5/3
To compute C[k] for k ≠ 0 and k ≠ 5, we can use the trigonometric identity:
cos(x) sin(y) = 1/2 (sin(x + y) – sin(x – y))
Let x = 2kπ/3 and y = 2nπ/5, then:
cos(2kπ/3) sin(2nπ/5) = 1/2 (sin(2kπ/3 + 2nπ/5) – sin(2kπ/3 – 2nπ/5))
= 1/2 (sin(10knπ/15 + 6kπ/15) – sin(10knπ/15 - 2kπ/15))
= 1/2 (sin((2k + 3n)π/3) – sin((2k - n)π/3))
The first term is zero when (2k + 3n) is an odd multiple of 3, and the second term is zero when (2k - n) is an odd multiple of 3. Therefore, C[k] = 0 when k + 3n is odd or k - n is odd.
For k = 3n, we have:
C[3n] = (1/15) * Σ[m=0 to 14] (cos(2mπ/3) sin(2nπ/5))
= (1/30) * Σ[m=0 to 14] (sin((2m + 3n)π/3) – sin((2m - n)π/3))
= (1/30) * (sin(5nπ/3) – sin(nπ/3) + sin(7nπ/3) – sin(5nπ/3) + sin(9nπ/3) – sin(7nπ/3) + sin(11nπ/3) – sin(9nπ/3) + sin(13nπ/3) – sin(11nπ/3) + sin(15nπ/3) – sin(13nπ/3) + sin(17nπ/3) – sin(15nπ/3) + sin(19nπ/3) – sin(17nπ/3))
= (1/30) * (sin(nπ/3) – sin(19nπ/3)) = 0
Therefore, the only non-zero coefficients are C[0] = 5/3 and C[5] = -5/3. The magnitude and phase spectra are:
|C[0]| = 5/3, arg(C[0]) = 0
|C[5]| = 5/3, arg(C[5]) = π
For all other values of k, C[k] = 0, so the magnitude and phase spectra are zero.
To compute the Fourier coefficients of cos(x) sin(y) = 1/2 (sin(x + y) – sin(x – y))
x[n] = 1/2 (sin(2nπ/3 + π/2) - sin(2nπ/3 - π/2)) * 1/2 (sin(2nπ/5) - sin(-2nπ/5))
Using the formula for the Fourier coefficients of a sinusoidal signal:
C[k] = (1/N) Σ[n=0 to N-1] x[n] e^(-j2πnk/N)
we can compute the Fourier coefficients for x[n]:
C[k] = (1/N) Σ[n=0 to N-1] x[n] e^(-j2πnk/N)
= (1/N) [Σ[n=0 to N-1] 1/2 sin(2nπ/3 + π/2) e^(-j2πnk/N) - Σ[n=0 to N-1] 1/2 sin(2nπ/3 - π/2) e^(-j2πnk/N)] [Σ[n=0 to N-1] 1/2 sin(2nπ/5) e^(-j2πnk/N) - Σ[n=0 to N-1] 1/2 sin(-2nπ/5) e^(-j2πnk/N)]
= 1/4 [C1(k-2/3) - C1(k+2/3)] [C1(k-2/5) - C1(k+2/5)]
where C1(k) is the Fourier coefficient of the signal cos(2nπ/3), which is given by:
C1(k) = (1/N) Σ[n=0 to N-1] cos(2nπ/3) e^(-j2πnk/N)
= (1/N) Σ[n=0 to N-1] 1/2 [e^(-j2πnk/3) + e^(j2πnk/3)]
= 1/2 [δ(k-1/3) + δ(k+1/3)]

explain why the reading on a scale would be less after leaving the top floor and heading downward.
The reading on a scale could be less after leaving the top floor and heading downward due to gravity.
All objects that have mass or energy are subject to the fundamental natural force of gravity. It is the force that draws two objects together and maintains the orbits of things like planets, galaxies etc. The force of gravity is proportionate to an object's mass and inversely linked to the square of the distance among both. As a result, the gravity around two objects will be more considerable and closer if they are together.
Several events, like maintaining people and other objects on the surface of the Earth, creating ocean tides, and causing objects to fall to the ground when dropped, are caused by gravity. Due to its importance in helping to comprehend the mobility and behavior of celestial objects, it is also a fundamental idea in the sciences of astrophysics. Because gravity has an influence on the body, the reading on a scale could be lower as you descend from the top floor.

a. True
b. False
Recruiters have completely stopped using newspaper ads as a tool for external recruitment because job seekers use the Internet almost exclusively even in smaller cities and towns. - False
Although the majority of job seekers today utilise the Internet as their main source of job searching, businesses and recruiters still use newspaper ads as a technique for external hiring In order to reach a larger pool of candidates, many businesses still utilise a combination of traditional print marketing, social media, and online job boards.
Newspaper ads still have certain benefits, though, such as reaching a different group of job seekers who might not be as active online. Additionally, newspapers are a more efficient approach to contacting potential candidates in smaller towns and cities where there may not be as much internet job search activity. Therefore, it is still a tool that some businesses and recruiters utilise in their hiring processes, particularly when attempting to connect with a larger and more varied pool of prospects.

What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
Given is a triangle and the three side lengths.
We have the area of a triangle is,
Area of the triangle = [tex]\frac{1}{2}[/tex] × base × height
We have base = 5/4 cm
Area of the triangle can be found using the Heron's formula.
Heron's formula states that,
Area of a triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where s is the semi perimeter = (a + b + c) / 2 and a, b and c are the side lengths.
Given 5/4 cm, 1 cm and 3/4 cm are the side lengths.
s = (5/4 + 1 + 3/4) / 2 = 3/2
Area = [tex]\sqrt{\frac{3}{2}(\frac{3}{2} -\frac{5}{4} )(\frac{3}{2}-1)(\frac{3}{2}-\frac{3}{4} ) }[/tex]
= [tex]\sqrt{\frac{9}{64} }[/tex]
= [tex]\frac{3}{8}[/tex] cm²
Substituting in the formula A = [tex]\frac{1}{2}[/tex] × base × height,
[tex]\frac{3}{8}[/tex] = [tex]\frac{1}{2}[/tex] × [tex]\frac{5}{4}[/tex] h
h = [tex]\frac{3}{5}[/tex] cm
Hence the height is 3/5 cm.

is finding the limit of a function as n tends to infinity the best way to find small o notation of that function
Yes, This statement "f(n)/g(n) as n goes to infinity = 0" is true, in this little o notation means that f(n) grows much slower than g(n) as n becomes large.
"f(n)/g(n) as n goes to infinity = 0" means that as n approaches infinity, the ratio of f(n) to g(n) gets arbitrarily small. This is a formal way of saying that g(n) grows faster than f(n), or equivalently, that f(n) is "smaller" than g(n) in the long run. Specifically, the little-o notation represents a formal definition of this concept: f(n) is said to be "little-o" of g(n) (written as f(n) = o(g(n))) if and only if f(n)/g(n) approaches 0 as n approaches infinity. In other words, if for any positive constant ε, there exists a positive constant N such that for all n > N, |f(n)/g(n)| < ε.

How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the rate of change.b is the intercept, representing the value of y when x = 0.From the table, the parameters are given as follows:
m = 3, as when x increases by 2, y increaes by 6.b = 1, as when x = 0, y = 1.Hence the function is defined as follows:
y = 3x + 1.
To obtain the inverse function, we exchange the variables x and y and then isolate y, thus:
x = 3y + 1
3x = x - 1
y = (x - 1)/3
Hence the numeric value of the inverse function at x = 10 is given as follows:

Solve for x.
a) 7
b) -11
c) -6
d) -10
Answer:
b) - 11
Step-by-step explanation:
The two triangles ΔJKL and ΔGHK are similar since
LK = 2LH
JK = 2JK
(ratios of sides are same)
and the included angle ∠K is common to both triangles
So the sides are in the ratio 2:1 for larger to smaller triangle. Each side of the larger triangle is twice the length of the corresponding side of the smaller triangle
This means the ratio of side JL of the larger triangle ΔJKL must be twice the length of side GH of the smaller triangle ΔGHK
i.e.
JL = 2 x GH
We are given these sides as expressions in x
∴ x + 27 = 2(2x + 30)
x + 27 = 4x + 60
Subtract 4x from both sides:
x - 4x + 27 = 4x - 4x + 60
-3x + 27 = 60
Subtract 27 from both sides-3x = 60 - 27 = 33
==> 1
- 3x = 33
Divide by -3 both sides
-3x/-3 = 33/-3 = -11
x = -11
Answer b)
Do not be confused by the fact that x is negative. Many students get confused because they associate x as a length. x is just a variable used in the equations
The actual lengths will be positive
GH = 8 and JL = 16

Determine whether the following arguments are best interpreted as being inductive or deductive. Also state the criteria you use in reaching your decision (i.e., the presence of indicator words, the nature of the inferential link between premises and conclusion, or the character or form of argumentation).
Contrary to the common notion that women tend to be chatty compared to men, little difference exists between the sexes in terms of talkativeness. Over a five-year period researchers placed unobtrusive microphones on 396 college students in various fields, at campuses in Mexico as well as in the United States. They found that both men and women spoke about 16,000 words per day.
This argument is best interpreted as inductive. The presence of empirical evidence in the form of research data suggests that the conclusion is based on empirical observations and generalization.
The argument uses evidence to make a generalization about the talkativeness of men and women, which is the characteristic of inductive reasoning. Additionally, the lack of logical or deductive inferential links between premises and conclusion supports the inductive interpretation of the argument.on:
Inductive reasoning is a type of reasoning in which a conclusion is drawn based on observations or evidence, rather than from logical deduction. Inductive reasoning involves making generalizations from specific observations or examples

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Answer: 25%
Step-by-step explanation:
The answer is 25%. This is calculated by dividing the number of grams of carbohydrates from whole grains (55 grams) by the total number of carbohydrates eaten (220 grams). This gives 0.25, which can be expressed as 25%. Therefore, Osvoldo consumed 25% of his carbohydrates from whole grains today.
Answer:
Osvoldo only got 25% of his grams of carbohydrates from whole grains today, which is below his goal of 30%
Step-by-step explanation:
To find the percentage of Osvoldo's carbohydrates that came from whole grains, we can use the formula:
percentage = (part/whole) x 100%
where "part" is the number of grams from whole grains, and "whole" is the total number of grams of carbohydrates. So we have:
percentage = (55/220) x 100%
percentage = 0.25 x 100%
percentage = 25%
Therefore, Osvoldo only got 25% of his grams of carbohydrates from whole grains today, which is below his goal of 30%.
