You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.
What is Simple Interest ?
Simple interest can be defined as the ratio of product of principal amount , rate , time and hundred.
The interest on your loan can be calculated using the formula:
Interest = Principal x Rate x Time
In this case, the principal is $400, the rate is 8% (or 0.08 as a decimal), and the time is 2 years.
So, plugging in the numbers:
Interest = $400 x 0.08 x 2 = $64
Therefore, the total amount you will have to pay back is the sum of the principal and the interest, which is:
Total = Principal + Interest
= $400 + $64 = $464
Hence, You will have to pay back a total of $464 over the course of the two-year loan, which includes the $400 principal plus $64 in interest.

Step-by-step explanation:
Since you don't know how much Sanjay picked you can only explain as a variable. So just put 17 next to p which is 17*p
f(x)= 1/x, vertically stretched by a factor of 7, reflected in the y-axis, translated 5 units to the right, and translated 3 units downward.
Answer:
-7/(x-5) - 3
Step-by-step explanation:
First off, to reflect an equation in the y axis, just multiply by -1. Now that it is reflected, to stretch an equation by a factor of 7, multiply it by 7. Now we have -7/x.
Then, to move an equation down by 3 units, simply subtract it by 3. Now we have -7/x - 3.
Lastly, since you want to translate it 5 units to the left, you want the equation to be undefined at x = 5 (because originally it is undefined at x = 0). To do that, set the denominator to x - 5. We arrive at our answer: -7/(x-5) - 3.
Using translation concepts, it is found that the new definition for the function is:
[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]
----------------------------
The parent function is:
[tex]f(x) = \frac{1}{x}[/tex]
A vertical stretch by a factor of a means that the function is multiplied by a.Factor of 7, thus:[tex]g(x) = 7 \times \frac{1}{x} = \frac{7}{x}[/tex]
Reflection over the y-axis means that we have g(-x), thus:[tex]g(-x) = \frac{7}{-x} = -\frac{7}{x}[/tex]
Translating a units to the right is g(x - a), 5 units, thus:[tex]g(x) = -\frac{7}{x - 5}[/tex]
a units downward means that a is subtracted from the function, 3 units, thus:[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

Bob has 10 apples after 4 hours he has 6 apples. Find the slope l the line that indicates the rate that bob eats apples at.
Answer:
y= -x + 10
Step-by-step explanation:
At 0 hours = Bob has 10 apples
At 4 hours = Bob has 6 apples
In 4 hours Bob has eaten 4 apples
Using linear graphs where y = the apples remaining and x = the hours passed
y = mx + c
We already know some coordinates:
(0,10) - 0 hours 10 apples remaining
(4,6) - 4 hours 6 apples remaining
c is the y intercept and m is the gradient
We already have the y intercept (where x = 0) which is (0,10)
So first part of our rule is done: y = mx + 10
The gradient is rise / run
Rise = -4 and Run = 4
-4/4 = -1
So the gradient is -1 and we add that to our rule
So final rule is y = -x + 10

a) let n be the number of hamburgers Eva bought. Set up an equation that models the information given in the problem
b) how many hamburgers did Eva by?
I need a answer by Monday
Answer:
Number of hamburgers bought = 4
Number of hotdogs bought = 9
Step-by-step explanation:
Let
Number of hamburgers bought = n
Number of hotdogs bought = n + 5
Hamburgers cost = $6.25
Hotdogs cost = $3.75
Total cost = $58.75
6.25n + 3.75(n + 5) = 58.75
Open parenthesis
6.25n + 3.75n + 18.75 = 58.75
Collect like terms
6.25n + 3.75n = 58.75 - 18.75
10n = 40
Divide both sides by 10
n = 40 / 10
= 4
n = 4
Number of hamburgers bought = n = 4
Number of hotdogs bought = n + 5
= 4 + 5
= 9

Please solve this question.(Quadratic equation)
Answer: 28
Step-by-step explanation:
Let x represent the digit in the tens place and y represent the digit in the ones place. xy → 10x + y
The square of the sum of the digits is 100.
EQ1: (x + y)² = 100 → x + y = 10
2 is subtracted from 3 times the number is the digits reversed.
EQ2: 3(10x + y) - 2 = 10y + x → 30x + 3y - 2 = 10y + x → 29x - 7y = 2
Solve the system of equations using the Elimination method:
EQ1: x + y = 10 → 7(x + y = 10) → 7x + 7y = 70
EQ2: 29x - 7y = 2 → 1(29x - 7y = 2 → 29x - 7y = 2
36x = 72
÷36 ÷36
x = 2
Substitute x = 2 into either of the equations to solve for y.:
EQ1: x + y = 10
2 + y = 10
y = 8
The digit is: 28

If you wanted to find the difference of 6/25-4/5,what common denominator should you choose?why?
Answer:
25
Step-by-step explanation:
25 should be chosen as the common denominator. 5 is a possible common denominator because the other fraction has a denominator of 5 and 25 is divisible by 5, however, the numerator cannot be evenly divided by 5. Attempting to do so would cause a much more difficult equation. On the other hand, the denominator 5 can be changed to 25 by multiplying by 5, and 4 can also be changed by multiplying by 5.
4/5 x 5 = 20/25
6/25 - 20/25 = -14/20 = -7/10

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)
Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.
[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.

Step-by-step explanation:
1. Select all of the true statements.
A. Pi is the area of a circle of radius 1.
B. Pi is the area of a circle of diameter 1.
C. Pi is the circumference of a circle of radius 1.
D. Pi is the circumference of a circle of diameter 1.
E. Pi is the constant of proportionality relating the diameter of a circle to its circumference.
F. Pi is the constant of proportionality relating the radius of a circle to its area.
We want to see which of the given statements about the number pi are true.
The correct options are: a, d, and e.
First, let's talk a little bit about the number pi.
The irrational number pi is defined as the quotient between a circle's circumference and its diameter.
So if we know that a circle has a diameter D, the circumference of that circle is given by:
C = pi*D
Now let's analyze each option to see which ones are true.
a) "Pi is the area of a circle of radius 1."
The area of a circle of radius R is given by:
A = pi*R^2
So if the radius of this circle is R = 1. we have:
A = pi*1^2 = pi
So the area of this circle is pi, thus the statement is true.
b) "Pi is the area of a circle of diameter 1."
The diameter is twice the radius, so the radius of this circle is 0.5, we know that pi is the area of a circle of radius 1, not a circle of radius 0.5, so this is false.
c) "Pi is the circumference of a circle of radius 1."
The circumference of a circle of radius R is given by:
C = pi*2*R
If the radius is equal to 1 we have R = 1, then:
C = pi*2*1 = 2*pi
The circumference of this circle is 2*pi, not pi, so this is false.
d) "Pi is the circumference of a circle of diameter 1."
We know that the circumference of a circle of diameter D is:
C = pi*D
So if D = 1, we have:
C = pi*1 = pi
So the circumference of this circle is equal to pi, thus, this statement is true.
e) "Pi is the constant of proportionality relating the diameter of a circle to its circumference."
A proportional relation is:
y = k*x
where k is the constant of proportionality.
The relation between the circumference is given by:
C = pi*D
So yes, pi is the constant of proportionality, this is true.
F) "Pi is the constant of proportionality relating the radius of a circle to its area."
The area equation is:
A = pi*R^2
note that the radius is squared, so this is not a proportional relation, then the statement is false.
Finally, we can conclude that the true statements are:
a, d, e.

Step (2)
Question told us that CED = 4 x + 1
Thus : BEC = CED = 4 x + 1

Step (3)
AD is a straight line which means its angle size is equal to 180° degrees.
So :
AEB + BEC + CED = 180
( 11x - 12 ) + ( 4x + 1 ) + ( 4x + 1 ) = 180
11x + 4x + 4x - 12 + 1 + 1 = 180
19x - 10 = 180
Plus sides 10
19x - 10 + 10 = 180 + 10
19x = 190
Divided sides by 19
[tex] \frac{19}{19}x = \frac{190}{19} \\ [/tex]
[tex]x = 10[/tex]
So : x = 10°
_________________________________
Step (4)
AEB = 11x - 12
AEB = 11(10) - 12
AEB = 110 - 12
AEB = 98°

BEC = CED = 4x + 1
BEC = CED = 4(10) + 1
BEC = CED = 41°
