Question

an engineer uses a linear model to calculate the amount of water in a reservoir based on the number of hours the reservoir drains. identify the rate the water is draining from the reservoir. enter your answer. the reservoir drains ? gallons per hour. hours water remaining (gal) 4 15.362 7 9.254

Explanation:

Step1: Calculate change in water

Find the difference in water remaining.
$15.362 - 9.254=6.108$

Step2: Calculate change in hours

Find the difference in hours.
$7 - 4 = 3$

Step3: Calculate drainage rate

Divide change in water by change in hours.
$\frac{6.108}{3}=2.036$

Answer:

$2.036$
