A rocket was launched into the air from a podium 6 feet off the ground. The rocket path is represented by the equation h(t)=-16t

^2+120t+6, where h(t) represents the height, in feet, and t is the time, in seconds. Find the average rate of change from the initial launch to the maximum height.

Answer:

60

Step-by-step explanation:

The given function is:

h(t)=-16t^2+120t+6

The average rate of change of h(t) from t=a to t=b is given by:

\frac{h(b)-h(a)}{b-a}

We can rewrite this function as: h(t)=-16(t-3.75)^2+231

The maximum height of the rocket is 231 and it occurs at t=3.75

\implies h(3.75)=231

The initial launch occurs at: t=0

and h(0)=-16(0)^2+120(0)+6=6

The average rate of change from the initial launch to the maximum height is

\frac{h(3.75)-h(0)}{3.75-0}=\frac{231-6}{3.75-0} =60

(4ab - 8a 2 + 12ac) ÷ 4a
ioda

we are given

\frac{(4ab-8a^2+12ac)}{4a}

we can see that

4a is in multiple in numerator

so, we can factor it out

\frac{4a(b-2a+3c)}{4a}

now, we can cancel 4a

and we get

(b-2a+3c).............Answer
