While on the golf course last weekend marc hit into the rough landing the ball behind a tall tree. his best option was to get it high enough to get over the tree and hopefully
come down in the fairway for his next shot. so with a mighty swing he hit the ball into
the air and was surprised to see the ball hit near the top of a 300 foot tall tower that
he had not noticed.
the formula is: h(x)= -16x^2 +20x where h is the height of the ball and
x is the number of seconds the ball is in the air.
how high did marc actually hit the ball?

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
