The formula h = -16t^2 + vt + s gives the height of an object tossed upward where v represents the initial velocity, s represents the initial height, and t represents time. A golf ball is hit straight up from the ground level with an initial velocity of 72 ft/sec. Find the number of seconds it takes to reach that height.

The manager of 100 apartments knows that at $600 rent per month, all apartments will be rented. For each 25 increase, one apartment will not be occupied. Let x represent the number of $25 increases to the rent.

Write the monthly revenue as a function of x.

• Revenue R(x) = (600 + 25x)(100 - x)

• Revenue R(x) = (600 - 25x)(100 + x)

• Revenue R(x) = (600 + 25x)(100 + x)

• Revenue R(x) = (600 - 25x)(100 - x)
