Maria drops a hammer from an apartment that is 30 meters above the ground. The

height of the hammer in meters, h, after t seconds is modeled by the function

h(t) = -t - 2t + 30. Find the approximate number of seconds it will take for the

hammer to hit the ground. Round your answer to the nearest whole number.

A.0

B.5

C.10

D.30

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
