The point halfway between the two cities would be the midpoint, which is found by averaging the x and y coordinates. In this case the point would be ((3+7)/2, (4+1)/2) = (5, 2.5). The distance between the stadium and the high school can be found using the distance formula and then multiplying by 10.9 miles. That would get us 10.9sqrt((7-3)^2+(4-1)^2) = 54.5 miles if I did that mental math right.
Answer:
A1 / B1 ;
(D1 - A1) / B1 ;
(A1 - E1*A1) / B1
Step-by-step explanation:
A1 = original price of car
B1 = annual Depreciation amount
Number of years it will take for the car to depreciate totally :
Using the straight line Depreciation relation :
y = mx + c
c = intercept = initial or original value of car
m = annual Depreciation amount
x = number of years
y = value after x years
For total Depreciation, final value, y = 0
0 = mx + c
mx = - c
x = - c / m
Hence, x = A1 / B1
B.)
D1 = car value
Length it will take for car to depreciate to value in D1 :
y = mx + c
y = D1; m = B1 ; c = A1
D1 = B1x + A1
B1x = D1 - A1
x = (D1 - A1) / B1
C.)
E1 = decrease percentage
Time it takes for car to decrease by percentage in E1
y = E1 * A1
E1 * A1 = B1x + A1
(A1 - E1*A1) = B1x
x = (A1 - E1*A1) / B1
Exponential equation are functions defined by 
The equation that could represent Rainey graph must take the form 
<h3>How to determine the equation</h3>
An exponential equation is represented as:
Where:
- a represents the initial value
- b represents the rate
The initial value (a) is 15.
So, the equation becomes
The graph is not given;
So, the equation cannot be determined.
Assume that the rate is 2.
Then the function would be:

Answer:
n < 20
Step-by-step explanation:
2n – 1 < 39
Add 1 to each side
2n – 1+1 < 39+1
2n < 40
Divide each side by 2
2n/2 < 40/2
n < 20
