The equation to find Amy's earning after tutoring for 15 hours is 300 dollars.
<h3>How to find an equation?</h3>
She earn 20 dollars for each hours she tutors.
E = earnings in dollars
H = hours of tutoring
The equation relating E and H are as follows:
E = 20H
Therefore, the equation to find Amy's earning after tutoring for 15 hours is as follows;
E = 20H
E = 20 × 15
E = 300 dollars
Therefore, Amy's tutoring for 15 hours is 300 dollars.

Answer:
Step-by-step explanation:
Average Temperatures Suppose the temperature (degrees F) in a river at a point x meters downstream from a factory that is discharging hot water into the river is given by
T(x) = 160-0.05x^2
a. [0, 10]
For x = 0
T(0) = 160 - 0.05 × 0^2
T(0) = 160
For x = 10
T(10) = 160 - 0.05 × 10^2
T(10) = 160 - 5 = 155
The average temperature
= (160 + 155)/2 = 157.5
b. [10, 40]
For x = 10
T(10) = 160 - 0.05 × 10^2
T(10) = 160 - 5 = 155
For x = 40
T(10) = 160 - 0.05 × 40^2
T(10) = 160 - 80 = 80
The average temperature
= (80 + 155)/2 = 117.5
c. [0, 40]
For x = 0
T(0) = 160 - 0.05 × 0^2
T(0) = 160
For x = 40
T(10) = 160 - 0.05 × 40^2
T(10) = 160 - 80 = 80
The average temperature
= (160 + 80)/2 = 120
Answer:
False
Step-by-step explanation:
Measurements are too long on the A leg and B leg for it to be connected by a 12 in leg.
T = 2π√(l/g)
<span>=> T = 2π√[5m/(9.8m/s²)] </span>
<span>=> T ≈ 4,49s </span>
Answer:
Inverse variation
Step-by-step explanation:
Given equation is 
.
Now we need to identify the type of variation represented by .
We know that there are two type of variations direct and inverse.
If y and x are in direct variation then we write equation as 
.
where k is the constant of variation.
If y and x are in inverse variation then we write equation as 
.
Given equation looks similar to .
So that means finala answer is "Inverse variation".
