Answer:
Step-by-step explanation:
Inches per hour is the rate we are looking for here, which will then be the slope of the linear equation. Slope is the same thing as the rate of change. While this may not seem all that important right now, it's actually a HUGE concept in higher math, especially calculus!
If the pool is filling at a rate of 2 inches per every 4 hours, then by dividing, we get that the rate is 1 inch every 2 hours, which translates to a slope of 1/2. Creating an equation with this slope:
Let's check it. We are told that after 4 hours there are 2 inches of water in the pool. That means if we plug in 4 for t and solve for w, we should get w = 2:
and
w = 2. So we're good!

Answer:
4 in
Step-by-step explanation:
The distance in inches can be found by integrating the velocity in inches per second.

This integral is designed to be easy enough to do <em>without a calculator</em>. A calculator can do integrals like this pretty easily.
9x+19+6x+56=180
15x+75=180
Subtract 75 on both sides to get
15x=105
x=7
