1. Given the functions a(x) = 3x − 12 and b(x) = x − 9, solve a[b(x)] and select the correct answer below.a[b(x)] = 3x2 − 21
a[b(x)] = 3x2 − 39
a[b(x)] = 3x − 21
a[b(x)] = 3x − 39

Answers

Answer 1
Answer: I think the answer is A: a[b(x)] = 3x2-21 because if you make this whole expression into an equation then solve x, you will get answer A. Hope this helps! :)

Step-by-step explanation:

A person springs off a 12-foot high diving board with an initial velocity of 10 feet per second. How many seconds does it take the person to hit the water?

Answers

Answer:

1.2 seconds

Step-by-step explanation:

The height of the diving board above water is 12 feet.

The person dives with an initial velocity of 10 feet per second.

The time taken is gotten by dividing the height jumped by the velocity at which the person dived.

That is:

t = d / s

where d = height jumped = 12 ft

s = velocity = 10 ft/s

Therefore:

t = 12 / 10 = 1.2 seconds

It took the person 1.2 seconds to hit the water.
