Slow Joe raised $329.90 more than Fast Freddy.

Steps:

Slow Joe: 93.15 x 4 miles = 372.60

Fast Freddy: 93.15 x (4 x 0.2) = $37.26

Difference: 372.60 - 37.26 = $329.90

Slow Joe raised $372.60 for charity by riding 4 miles of the course for the 2021 Las Vegas Charity Bike-A-Thon. This was accomplished by Slow Joe's donators pledging a combined total of $93.15 for every mile Joe traveled from start to finish. In comparison, Fast Freddy raised $42.70 per mile for traveling 20% of the course. To calculate the difference between the two, Slow Joe's total was calculated by multiplying the amount per mile by the number of miles traveled (93.15 x 4 = 372.60). Fast Freddy's total was calculated by multiplying the amount per mile by the percent of the course traveled (93.15 x (4 x 0.2) = 37.26). When the total amount raised by Slow Joe was subtracted from the total amount raised by Fast Freddy, the difference was $329.90. Therefore, Slow Joe raised $329.90 more than Fast Freddy.

Each flower that Gavin bought will cost $0.875 and the approximate value of each flower will be $0.90

6.5 dozen of carnations = 6 × 12 + 6 (one dozen has 12 units)

(half dozen is half of 12 that is 6)

the total number of flowers Galvin bought = 72 + 6 = 78

total amount Gavin spent on carnations is $68.25

let the amount spent on one flower be x

then the ratio of flower to amount of flowers

ratio = [tex]\frac{net quantity}{amount}[/tex] = [tex]\frac{78}{68.25}[/tex] = [tex]\frac{1}{x}[/tex]

therefore, x = 1 × [tex]\frac{68.25}{78}[/tex]

x = 0. 875 or 0.88

x ≈ 0.90

This can be solved using the concept of triangle similarity.

Triangulus, which means "three-cornered" or "having three angles," is a Latin word with roots in tri-, "three," and angulus, "angle or corner." Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The summation of the triangle's three angles equals 180 degrees. Triangles can be classified as equilateral, isosceles, or scalene depending on how long their sides are.

Consider, the triangle ABC and the mid-segment line becomes CD.

Now, from similarity

Δ DBA ≅ Δ ABC

AB² = BC. BD ............... (i)

Δ ADB ≅ Δ ABC

AD² = BD. CD ............. (ii)

thus, Δ ADC ≈ Δ ABC

AC² = BC. CD

Thus, q² = (17.5 + 21) × (17.5)

or, q² = 673.75

In mathematics, the term "discrete" is often used to refer to objects or structures that are distinct and separate, rather than being continuous or flowing. In the context of this course, the term "discrete" is used to describe a particular branch of mathematics known as "discrete mathematics" or "discrete structures."

Discrete mathematics is concerned with mathematical structures that are countable and finite, rather than continuous or infinite. These structures are typically represented by sets, graphs, or other discrete objects, and can be used to model a wide range of phenomena, from computer algorithms to social networks.

One of the key features of discrete structures is that they are composed of individual, separate elements, rather than being continuous or flowing. For example, a set of integers is a discrete structure, because it consists of separate, distinct integers, rather than a continuous range of numbers. Similarly, a graph is a discrete structure, because it consists of separate vertices and edges, rather than a continuous line.

Because of their discrete nature, these structures can be analyzed and manipulated using a range of mathematical tools and techniques, such as combinatorics, graph theory, and probability theory. This makes discrete mathematics a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.

In contrast, continuous structures, such as real numbers or geometric shapes, are often analyzed using calculus or other techniques that deal with the infinite and continuous nature of these objects.

In summary, when we talk about "discrete structures" or "discrete mathematics," we are referring to mathematical objects and structures that are countable, finite, and composed of individual, separate elements. These structures can be analyzed and manipulated using a range of mathematical tools, and are a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.

The expression as product is sin(a)(4 + 2cos(a) - 4sin²(a))

From the question, we have the following parameters that can be used in our computation:

sin(a)+sin(2a)+sin(3a)

By sine rule, we have

sin(a)+sin(2a)+sin(3a) = sin(a) + 2sin(a)cos(a) + sin(3a)

Factor out sin(a)

sin(a)+sin(2a)+sin(3a) = sin(a)(1 + 2cos(a)) + sin(3a)

Expanding sin(3a), we have

sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a)) + 3sin(a) - 4sin³(a)

So, we have

sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a) + 3 - 4sin²(a))

Evaluate the like terms

sin(a) + sin(2a) + sin(3a) = sin(a)(4 + 2cos(a) - 4sin²(a))

Step-by-step explanation:

yea cuz we smart :))

so we know the EQUATion of the line, now let's work out the inequality of it.

the shaded area is the "true" region or area, and the non-shaded is the "false" region, hmmm let's work our way from the "false" region.

first off, the line is solid, that means the line includes values in the inequality, meaning the shaded part extends to the borderline, so the inequality will be either ⩾ or ⩽, let's work it out from the "false" region, by picking out a point there, hmmm let's use say x = 6 and y = -4, so the point is (6 , -4) and let's plug it in the EQUATion.

[tex]y ~~ \square ~~ \cfrac{3}{4}x-3\hspace{5em}(6~~,~-4)\qquad \implies \qquad -4 ~~ \square ~~ \cfrac{3}{4}(6)-3 \\\\\\ -4 ~~ \square ~~ \cfrac{18}{4}-3\implies -4 ~~ \square ~~ \cfrac{9}{2}-3\implies -4 ~~ \square ~~ \cfrac{9-6}{2}\implies -4 ~~ \square ~~ \cfrac{3}{2} \\\\\\ -4 ~~ \square ~~ 1.5\qquad \textit{is -4 greater or less than 1.5?}[/tex]

well, clearly -4 is less than 1.5, however to  make that a false statement, we can say that -4 is more than 15, now, is not true, is "false" and since we're working from the "false" region, that is what we need, "more than", or ⩾

[tex]{\Large \begin{array}{llll} y\geqslant \cfrac{3}{4}x-3 \end{array}}[/tex]

now, bear in mind that we could have started from the "true" region, the shaded one, and pick a point in it like (0 , 0), if you test, that gives us something like 0 [ ] -3, to make that true, we make it 0 ⩾ -3, because that is true, 0 is really greater than -3, and working for the "true" region, that's what we need.

Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.

A radian is a unit of measurement for angles in mathematics. It is defined as the ratio of the length of an arc of a circle to the radius of the circle. In other words, one radian is equal to the angle created at the center of a circle by an arc that is equal in length to the radius of the circle.

Radians are used as a more natural and convenient way to measure angles than degrees, especially in calculus and other branches of mathematics that deal with the study of curves and functions. For example, the trigonometric functions (sine, cosine, and tangent) are defined in terms of radians, and the derivatives of these functions are easier to work with in radians than in degrees

To convert from revolutions per minute to radians per second, we need to divide by the number of minutes in one hour and multiply by the number of radians in one revolution. We can write this conversion as:

4700 rev/min * (2π rad/rev) / (60 min/hr) = w rad/s

where w denotes the angle's rotational speed in radians per second. Plugging in the conversion factor for one revolution, we get:

w = 4700 rev/min * (2π rad/rev) / (60 min/hr) = (4700 * 2π) / 60 = 157.07 rad/s

Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.

The slope of the ocean floor is: slope = (y2 - y1) / x

What is slope?

The slope or gradient of a line in mathematics is a quantity that specifies both the direction and the steepness of the line.

The slope of the ocean floor can be found by using the formula for the slope of a line:

slope = (change in y) / (change in x)

where the change in y is the difference in depth between the edge of the continental shelf and the beginning of the oceanic crust, and the change in x is the distance along the ocean floor between these two points.

Let's call the depth of the water at the edge of the continental shelf "y1" and the depth of the water at the beginning of the oceanic crust "y2". Then, the change in y is:

change in y = y2 - y1

Similarly, let's call the distance along the ocean floor between these two points "x". Then, the change in x is:

change in x = x

So, the slope of the ocean floor is:

slope = (y2 - y1) / x

The new basic feasible solution will have x\ as a non-basic variable and a new basic variable with a value not equal to zero.

When a problem is in canonical form and the associated basic feasible solution is degenerate, this means that one of the basic variables has a value of zero. If the pivot operation is then performed with the basic variable with a value of zero extracted from the basis, the new basic feasible solution will have x\ as a non-basic variable and a new basic variable with a value not equal to zero. This is because the pivot operation involves exchanging the extracted basic variable with one of the non-basic variables.

Answer:

Let's call the initial fee "x". The equation for the total cost of using a computer for t minutes at the internet cafe can be expressed as:

C = x + 0.60t

Knowing that the total charge to use a computer for 5 minutes would be $6, we can use this information to find the value of x:

C = x + 0.60 * 5

6 = x + 3

x = 6 - 3

x = 3

So, the equation representing the total cost of using a computer for t minutes at the internet cafe is:

C = 3 + 0.60t

Answer:

Step-by-step explanation:

σ = sqrt [ Σ ( xi - μ )^2 / N ]

where:

σ is the standard deviation

Σ is the sum of the values

xi is the value of the i-th observation

μ is the mean of the population

N is the number of observations

First, we need to find the mean of the population:

μ = (20 + 30 + 13 + 10 + 22 + 37) / 6

μ = 132 / 6

μ = 22

Next, we can calculate the deviations of each observation from the mean:

20 - 22 = -2

30 - 22 = 8

13 - 22 = -9

10 - 22 = -12

22 - 22 = 0

37 - 22 = 15

Then, we square each deviation:

(-2)^2 = 4

8^2 = 64

(-9)^2 = 81

(-12)^2 = 144

0^2 = 0

15^2 = 225

We add up the squared deviations:

4 + 64 + 81 + 144 + 0 + 225 = 518

We divide by the number of observations and take the square root:

σ = sqrt [ Σ ( xi - μ )^2 / N ]

σ = sqrt (518 / 6)

σ ≈ 10.72

Therefore, the standard deviation of the population is approximately 10.72 dollars.

Answer & Step-by-step explanation:

To simplify the expression 3a + 6b - 8a + 9b, we can combine the like terms (terms with the same variable).

First, we can combine the 3a and -8a terms since they have the same variable 'a'. When we subtract 8a from 3a, we get -5a.

Then, we can combine the 6b and 9b terms since they have the same variable 'b'. When we add 6b and 9b, we get 15b.

Putting it all together, we get:

3a + 6b - 8a + 9b = -5a + 15b

Therefore, the simplified expression is -5a + 15b.

Answer:

p = -4

q = 9

Step-by-step explanation:

The vertex form of a parabola is:

y = a (x − h)² + k

Given that the leading coefficient is 1 and the vertex is (2,5):

y = (x − 2)² + 5

Distributing:

y = x² − 4x + 4 + 5

y = x² − 4x + 9

Alternatively, using calculus, if y = x² + px + q, then the derivative is:

dy/dx = 2x + p

The turning point occurs when the derivative is 0:

0 = 2x + p

0 = 2(2) + p

p = -4

Plugging in and solving for q:

y = x² − 4x + q

5 = (2)² − 4(2) + q

5 = 4 − 8 + q

q = 9
