Aspherical balloon is being inflated and the radius of the balloon is increasing at a rate of 2 cmys. (a) express the radius r of the balloon as a function of the time t (in seconds). (b) if v is the volume of the balloon as a function of the radius, find v 8 r and interpret it.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
