Part A) means that we have to find a composition of functions A and m
A(m(t))=π(9t)²=9πt²
part B)
A(m(t))=9πt²
A(m(2))=9*3.14*(2)²=113.04
<h2>
Plane's speed without wind i s 117.68 mph</h2>
Step-by-step explanation:
We have speed of plane without wind is x.
Distance to brothers place = 200 miles.
A headwind of 20 mph slowed down the plane's speed on the first leg of the trip
Speed to brothers place = x - 20
We have
Distance = Speed x Time

A tailwind of 20 mph sped up the plane on the return trip
Speed of return trip = x + 20
We have
Distance = Speed x Time

The entire trip took 3.5 hours.
That is

Plane's speed without wind i s 117.68 mph
Answer:
the seventh grader because the eighth graders got 58 which is more than 50 so the 7th grader would get the pts
Step-by-step explanation:
4⅚ ≥ x; subtract fifty-eight from both sides, divide by -12 from both sides, and you will have your answer.
NOTE: This is where you reverse your inequality symbol [dividing or multiplying by a negative].
