Answer:
AD = 4.5
Step-by-step explanation:
Since DE is parallel to AC and intersects 2 sides of the triangle it divides those sides in proportion, that is
= , substitute values
= ( cross- multiply )
8AD = 36 ( divide both sides by 8 )
AD = 4.5
I'm pretty sure it's 2.166667 miles per hour. Since its every hour you just need to divide that by 1 which is 2 1/6. And 2 1/6 in decimal form is 2.166667.

The expression y = 4.998 · is the exponential function that passes through the points (- 1, 5 / 3) and (3, 135).
<h3>How to derive an exponential function that passes through two given points</h3>
Herein we find the location of two points set on Cartesian plane that belongs to an exponential function of the form:
Where:
- A - y-Intercept of the exponential function.
- B - Growth factor
- x - Independent variable.
- y - Dependent variable.
Which is equivalent to the following logarithmic expression:
㏑ y = ㏑ A + B · x
If we know that (x₁, y₁) = (- 1, 5 / 3) and (x₂, y₂) = (3, 135), then the following system of equations is generated:
㏑ (5 / 3) = ㏑ A - B
㏑ 135 = ln A + 3 · B
Then, we solve the system by numerical methods:
㏑ A = 1.609 (A = 4.998), B = 1.098
And the exponential function is equal to y = 4.998 · .

Answer:
Option D) 5.4%
Step-by-step explanation:
we know that
$75.74 ----> represent the 100%
so
using proportion
Find the percentage that the amount of the customer's water bill increase
Let
x -----> the percentage that increase
$75.74/100%=($79.86-$75.74)/x
$75.74/100%=($4.12)/x
x=100*4.12/75.74
x=5.4%
