32 hours and this week he worked 33.25 hours. How much should his
biweekly (every 2 weeks) paycheck be for?
Answer:
James will receive a paycheck in the amount of $522.
Step-by-step explanation:
There are 2 ways you can go at finding the answer. The first way is by adding 32 hours and 33.25 hours together to get a total of 65.25 hours. Then multiply 65.25 hours by $8 to get $522. The second way is multiplying 32 hours by $8 and get $256. Then multiply 33.25 hours by $8 to get $266. Finally add $256 and $266 up and you get $522. I hope this helps you!

What is the function g(x) created from f(x) = x2 by moving the graph left 7 units, adding vertical compression by a factor of 1 6 , and shifting the graph down 8 units?
Answer:
g(x) = (1/6)(x +7)^2 -8
Step-by-step explanation:
The transformation ...
g(x) = a·f(x -h) +k
represents vertical scaling by a factor of 'a', right shift by h units, and up shift by k units. You want the function g(x) for f(x) = x^2, a = 1/6, h = -7, and k = -8. Those transformations give you ...
g(x) = (1/6)(x +7)^2 -8

Find the largest value of $n$ such that $5x^2+nx+48$ can be factored as the product of two linear factors with integer coefficients.
Answer:
[tex]n = 241[/tex]
Step-by-step explanation:
Given
[tex]5x^2 + nx + 48[/tex]
Required
Determine the highest value of n
From the given equation, 5 is a prime number;
So, the factors of x² is 5x and x or -5x and -x
Since [tex]5x^2 + nx + 48[/tex] has all shades of positive terms, we'll make use of 5x and x
The factorized expression can then be:
[tex](5x + a)(x + b)[/tex]
Open the brackets
[tex]5x^2 + ax + 5bx + ab[/tex]
Equate this to the given expression
[tex]5x^2 + ax + 5bx + ab = 5x^2 + nx + 48[/tex]
[tex]5x^2 + (a + 5b)x + ab = 5x^2 + nx + 48[/tex]
By direct comparison;
[tex]5x^2 = 5x^2[/tex]
[tex](a + 5b)x = nx[/tex]
[tex]a + 5b = n[/tex] ---- (1)
[tex]ab = 48[/tex] --- (2)
From (2) above, the possible values of a and b are:
[tex]a = 1, b = 48[/tex]
[tex]a = 2, b = 24[/tex]
[tex]a = 3, b = 16[/tex]
[tex]a = 4, c = 12[/tex]
[tex]a = 6, b = 8[/tex]
[tex]a = 8, b = 6[/tex]
[tex]a = 12, b = 4[/tex]
[tex]a = 16, b = 3[/tex]
[tex]a = 24, b = 2[/tex]
[tex]a = 48, b = 1[/tex]
Of all these values; the value of a and b that gives the highest value of n is;
[tex]a = 1, b = 48[/tex]
So;
Substitute 1 for a and 48 for b in (2) [tex]a + 5b = n[/tex]
[tex]1 + 5 * 48 = n[/tex]
[tex]1 + 240 = n[/tex]
[tex]241 = n[/tex]
[tex]n = 241[/tex]
Hence, the largest value of n is 241
Answer:
Step-by-step explanation:
The two factors of $5x^2+nx+48$ must be in the form $(5x+A)(x+B)$. $A$ and $B$ must be positive integers to form the largest value of $n$. Therefore, $AB=48$ and $5B+A=n$. To form the largest value of $n$, $B$ must equal $48$. Therefore, $A=1$. \[5B+A=5(48)+1=\boxed{241}\]

The price of a cup of coffee was $2.10 yesterday. Today, the price rose to $2.25. Find the percentage increase. Round your answer to the nearest tenth
of a percent.
Answer:
Easy-peasy.
Step-by-step explanation:
2.45/2.10 = 1.167 (rounded to the nearest tenth of a cent).
That is, 2.45 is 116.7% of 2.10
Since $2.10 is 100% of 2.10,
2.45 is a 16.7 increase.
The solution is 7.1 %
The percentage increase in the price of the coffee is 7.1 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the percentage increase in the price of the coffee be represented as A
Now , the value of A is calculated by
Let the initial price of the coffee be = P
The value of P = $ 2.10
The increased price of the coffee be = Q
The value of Q = $ 2.25
Now , the equation will be
The percentage increase in the price A = ( increased price of the coffee - initial price of the coffee / initial price of the coffee ) x 100
Substituting the values in the equation , we get
The percentage increase in the price A = ( ( 2.25 - 2.10 ) / 2.10 ) x 100
The percentage increase in the price A = ( 0.15 / 2.10 ) x 100
The percentage increase in the price A = 0.0714 x 100
The percentage increase in the price A = 7.14 %
Therefore , the percentage increase is 7.1 %
Hence , the percentage increase in the price is 7.1 %

Answer:
A. 8.3
B.18.7
C. 10.4
D. 1.04
Step-by-step explanation:
p(x) = 0.03x² + 0.56x + 6.35
A. Determination of p(3)
p(x) = 0.03x² + 0.56x + 6.35
x = 3
p(3) = 0.03(3)² + 0.56(3) + 6.35
p(3) = 0.03(9) + 1.68 + 6.35
p(3) = 0.27 + 1.68 + 6.35
p(3) = 8.3
B. Determination of p(13)
p(x) = 0.03x² + 0.56x + 6.35
x = 13
p(13) = 0.03(13)² + 0.56(13) + 6.35
p(13) = 0.03(169) + 7.28 + 6.35
p(13) = 5.07 + 7.28 + 6.35
p(13) = 18.7
C. Determination of p(13) – p(3)
From A and B above,
p(13) = 18.7
p(3) = 8.3
p(13) – p(3) = 18.7 – 8.3
p(13) – p(3) = 10.4
D. Determination of p(13) – p(3) / 13 – 3
From C above,
p(13) – p(3) = 10.4
p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3
= 10.4 / 10

A cash box of $1 and $5 bills is worth $45. The number of $1 bills is 3 more than the number of $5 bills. How many of each bill does it contain?
Answer:
There are 10 $1 bills and 7 $5 bills
Step-by-step explanation:
7($5 bills) x 5
=35
7+3 (3 more $1 bills)
=10
10+35
=45
Answer:
$1: 10
$5: 7
Step-by-step explanation:
To find out how many of each bill is in the cash box, create an expression
x = the dollar bills
This makes the $5 bills 5x and the $1 bills x (this can also be 1x)
When it says "The number of $1 bills is 3 more than the number of $5 bills" This means that the number of $1 is x + 3 and the number of $5 is 5x
When you put it together the expression will be x + 3 + 5x = 45
First add x and 5x, making it 6x
Next subtract 3 from each side, which makes the equation 6x = 42
Lastly, divide 6 from each side, this means that x = 7
To find out how many bills there are substitute 7 wherever there is an x
This mean that the number of $1 is 7 + 3 (10), and the number of $5 bills are 5x7 (35), but its just 7 because they are $5 each

The square of a number is 3 less than four times the number. Which values could be the number?
Answer:
The numbers are 1 and 3Step-by-step explanation:
Let the number be x
The statement
The square of a number is 3 less than four times the number is written as
x² = 4x - 3
Solve the quadratic equation
We have
x² - 4x + 3 = 0
Write - 4x as a difference
That's
x² - x - 3x - 3 = 0
Factorize the expression
That's
x( x - 1) - 3( x - 1) = 0
( x - 1)( x - 3) = 0
x - 1 = 0 x - 3 = 0
x = 1 x = 3

A regression equation is obtained for a collection of paired data. It is found that the total variation is 20.711 , the explained variation is 18.592 , and the unexplained variation is 2.119 . Find the coefficient of determination.
Answer:
0.898
Step-by-step explanation:
The formula for the Coefficient of determination = ratio of explained variation to Total variation
From the above question, we have the following values
Explained variation = 18.592
Total variation = 20.711
The coefficient of determination = 18.592 : 20.711
= 18.592/20.711
= 0.8976872194
Approximately ≈ 0.898
Therefore, the coefficient of determination is 0.898

Hannah and Zach together earn $950 for an
advertising drop. They earn equal hourly rates
of pay. If Hannah worked for 10 hours and
Zach for 9 hours, how much
did Zach earn?
Answer:
$450
Step-by-step explanation:
First, write out an equation. We know that Hannah and Zach together earnes $950 and they get payed in equal hourly rates, so for now, in this step of solving the problem, we will be adding the number of hours each person worked together.
Hannah worked 10 hrs and Zach worked 9 hrs, so add 10+9 to get 19 hrs worked in all between the two of them.
Let "x" represent the amount of money made each hour, and form your equation.
Your equation would be: [tex]19x=950[/tex]
Then, just solve for "x". Divide both sides by 19.
[tex]\frac{19x}{19}=\frac{950}{19}\\x=50[/tex]
The "x=50" means that Hannah and Zach each earn $50 per hour.
Now, the question asks us to find the amount of money that Zach made. So, multiply 50 by only the number of hours Zach worked, which is 9.
[tex]50*9=450[/tex]
That means that Zach made a total of $450.
Tyrion can invest in an account earning 2.5% interest compounded monthly. If he invests $5000, ow much will he have in 7 years?
Answer:
$5925.51Step-by-step explanation:
We are going to be using the compound interest formula
Given data
principal P= $5000
N is time = 7 years

3 b). NO The sum of 3 ft + 4 ft gives 7ft which is not larger than 10 ft
4 Recall that larger angles opposite larger sides, and smaller angles oppose smaller sides in the triangle. Therefore, the smallest angle must be that opposite the 1 1/4 side that is angle [tex]\angle F[/tex] then angle d must follow (opposes side of length 2) and lastly angle E (since it opposes the largest side of length 2 1/8
