spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -8.8°F. Between 9am and noon, the temperature increased by 13.6°F. Between noon and 3pm, the temperature decreased by 6.9°F. Between 3pm and 6pm, the temperature went down 2.1°F. What was the temperature at 6pm?

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
