Final answer:
The unit rate for the given problem, 1/7 inch per 1/14 minute, is calculated by dividing the inches by the minutes. This simplifies to 2 inches per minute.
Explanation:
In mathematics, a unit rate is a rate in which the second number (or denominator) is one. When you are asked to write the rate 1/7 inch per 1/14 minute as a unit rate, you are being asked to find a rate that tells you how much of each quantity occurs for each single unit of the other quantity, in this case for 1 minute. To calculate this unit rate, divide the quantity in inches by the quantity in minutes.
In this problem, you can find the required unit rate by dividing (1/7) by (1/14), which simplifies to (1/7) * (14/1) = 2 inches. So, the unit rate for this problem is 2 inches per minute.

Step-by-step explanation:
To find the average rate of change we find
f(3) -f(0)
----------
3-0
We need to find f(3) = 1/4 (3)^2 -4 = 1/4 (9) -4 = 9/4 -4 = -7/4
f(0) = 1/4 (0)^2 - 4 = -4
f(3) -f(0)

1/4
Answer:
3/4
Step-by-step explanation:
The x values are 0 and 3. Use the formula y2-y1/x2-x1
Plug in the x factors into the orginal equation. Should look like the equations below:
f(x)=1/4(0)^2-4 -------> -4
f(x)=1/4(3)^2-4 --------> -7/4Now plug it in to the formula we saved earlier.
-7/4-(-4)/3-0= -7/4+4/3= -7/4+16/4/3
Then simplify it.
9/4/3, and in this case we have a fraction in a fraction and when this happens just multiply the equation by the x variables reciprical which in this case the x is 3 so the equation is multiplied by 1/3 and you would get 9/12. Now simplify that and you get 3/4.
