1. A school shirt is available in either long-sleeved or short-sleeved, in sizes small, medium, large, and extra large, and in one of two colors. How many different shirts is there?
2. A clown is shout out of a cannon with an initial upward velocity of 25m/sec^2. Ig h(t)= (16t^2)+25t+4 represents his path, and t represents time in seconds and h(t) represents his height above the ground, when will he reach the highest point of his travels? How high does he get?

1) Just multiply the possible choices in each parameter.
2) There is no such thing as a velocity of 25m/sec^2. Could you please put a proper question in.

2. Your function should be h(t) = -16t^2 + 25t + 4. He will reach the highest point when h'(t) = -32t + 25 = 0, or at
t = 25/32 seconds.
