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
Arte-miy333 [17]

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

Eve plays basketball. She makes 7 free throws for every 3 free throws that she misses. If she missed 27 free throws at
VikaD [51]
Well if she missed 27, we would need to divide 27 by 3 which gives us 9, then we’d multiply 7 by nine and it’s 63. She made 63 free throws

A right triangle has a base that measure 39 inches and a height that measures 80 inches. What is the length of its hypotenuse?
guajiro [1.7K]
The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)
