<h2>Option D is the correct answer.</h2>

Step-by-step explanation:

A radio station's signal has a radius of 100 miles.

Diameter = 2 x 100 = 200 miles

If you drive at a constant speed of 40 miles an hour

Speed of vehicle = 40 miles per hour.

We have

        Distance traveled = Speed X Time taken

        200 = 40 X Time

        Time = 5 hours

So after riding 5 hours the vehicle falls outside of signal range.

Option D is the correct answer.

KATRIN_1 [288]

Answer:

y = - 6

Step-by-step explanation:

Given

\frac{y}{2} + 9 = 6 ( subtract 9 from both sides )

\frac{y}{2} = - 3 ( multiply both sides by 2 to clear the fraction )

y = - 6

. Let f(x) = x2 and g(x) = x − 3. Evaluate (g ∘ f)(−2). 1 7 20 −20
lesya692 [45]

For this case we have the following functions:

f (x) = x ^ 2\\g (x) = x-3

We must find(g_ {0} f) (x)

By definition we have to:

(g_ {0} f) (x) = g (f (x))

So:

g (f (x)) = (x ^ 2) -3 = x ^ 2-3

We must evaluate the composite function for x = -2

g (f (-2)) = (- 2) ^ 2-3 = 4-3 = 1

ANswer:

g (f (-2)) = 1
