Check the picture below.
so, a cone, that fits inside the cylinder, will have the same height "h" and radius "r". Thus
speed =distance traveled over time taveled... the ansewr will be in kilometres per hour
-16t² + 180t
-16(2)² + 180(2)
-64 + 360
The fireworks height after 2 seconds is 296 feet
(t^2+1)^100
USE CHAIN RULE
Outside first (using power rule)
100*(t^2+1)^99 * derivative of the inside
100(t^2+1)^99 * d(t^2+1)
100(t^2+1)^99 * 2t
200t(t^2+1)^99
The answer is D. you can choose your words carefully
