Question

Use this piecewise function that gives the rate, r(t), in gallons per hour, at which a pool is being filled with water at

Answer 1

Answer:

The correct answer is "4500".

Explanation:

As per the question,

Total galloons of water will be:

=  $\int_{0}^{2}250 t \ dt+\int_{2}^{10}500 \ dt$

=  $250(\frac{t^2}{2} )^2_0+500(t)^{10}_2$

=  $125(4-0)+500(8-2)$

=  $125(4)+500(6)$

=  $500+4000$

=  $4500$

Thus the above is the appropriate option.
