b. 7115
c. 7490
d. 13,861

Answer 1

The answer is B I just to the test.

Answer 2

Answer: 7115 gallons

Explanation:

Given: Water was drained from a swimming pool.

The equation
`\hat{y}=14590\cdot0.95x` estimates the number of gallons of water remaining after x hours from the time it started draining.

At x=14, we have

`\hat{y}=14590\cdot0.95^(14)=7115.1779453\approx7115`

Hence, there were 7115 gallons of water in the pool after 14 hours of draining.
