Vinnie drives his car 210 miles and has an average of a certain speed. If the average speed had been 3mph more, he could have tr
Pachacha [2.7K]

Answer:

35 mph

Step-by-step explanation:

time = distance / speed

210 miles and has an average of a certain speed

t = 210 / s

If the average speed had been 3mph more, he could have traveled 228 miles in the same length of time

t = 228 / (s + 3)

Set equal

210 / s = 228 / (s + 3)

Cross multiply

210s + 630 = 228s

Subtract 210s from both sides

630 = 18s

Divie both sides by 18

35 = s

35 mph

Which of the following will form the composite function G(F(x)) shown
yKpoI14uk [10]

The composite function G(F(x)) = x² + 4 is formed with these following original functions:

D. F(x) = x² and G(x) = x + 4.

<h3>How to find the composite function of f(x) and g(x)?</h3>

The composite function of f(x) and g(x) is given as follows:

(f \circ g)(x) = f(g(x))

For g of f(x), we have that:

(g \circ f)(x) = g(f(x))

For this problem, we have that:

G(F(x)) = x² + 4.

Which is possible with option D, as:

G(F(x)) = G(x^2) = x^2 + 4
