Answer:
a) h: Number of hours
b) Slope of function
c) y-intercept
Step-by-step explanation:
We are given the following in the question:

The above function tells us about amount of money Amy has in her savings after each hour of work.
a) value of "h"
The above function tells us about the money saved by Amy after each hour of work.
Thus, h here stands foe the number of hours.
b) meaning of the coefficient h
Comparing the given function to a linear function:

Thus, coefficient of h is the slope of the function and tells the change in amount of money saved by Amy per unit hour or it tells the change in amount of money when there is a unit increase in hour.
c) meaning of constant
The constant is the y-intercept and tells the amount of money saved by Amy after she have worked for zero hours.
Answer:
y=2x+8
Step-by-step explanation:
An equation that is most suitible for this kind of problem is the slope intercept form with is y=mx+b.
m=slope
b=y-intercept
1: Find the slope
Use the formula y2-21/x2-x1
6-2/-1-(-3)=4/2=2
m=2
2: Find the y-intercept
For me personally, I think it is easiest to just graph the points, draw the line, then find where the line meets the y-axis.
b=8
<u>y=2x+8</u>

Answer:
DA/dt = 37 / 18
Step-by-step explanation:
We have the following information:
Sides of the rectangle L = length w = width
Area of the rectangle is : A = L* w
the rate of growing of the length ( as function of time ) 1 mile in 6 years
we can express that as :
DL/dt = 1 /6
And the rate of growing of the width ( as function of time ) 1 mile in 9 years
Dw/dt = 1/9
In 1995 dimensions of the rectangle were
L = 5 miles and w = 9 miles
Then:
A = L * w Taking derivatives
DA/dt = L * Dw/dt + w * DL/dt
DA/dt = 5 * (1/9) + 9 * (1/6) ⇒ DA/dt = 5/9 + 9/6
DA/dt = 111 / 54 ⇒ DA/dt = 37 / 18
