Question

water is steadily pumped out of a flooded basement. let v be the volume of water (in thousands of gallons) that remains in the basement t hours after the water began to be pumped. a linear model is shown below. a) how much water is in the basement after 3 hours of pumping? 12 thousand gallons b) after how many hours of pumping will 2 thousand gallons remain in the basement? 5.5 hours c) how much water was in the basement before any water was pumped out? thousand gallons complete parts a) through d).

Explanation:

Step1: Identify the y-intercept

The amount of water before pumping (t = 0) is the y - intercept of the linear graph. From the graph, when t = 0 (the y - axis), the volume v is 24 thousand gallons.

Answer:

24
