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

Answer:
84.8 is the mean
Step-by-step explanation:
Add the grades from the quizzes which gives you 424, then divide by 5 which then gives you your answer of 84.8
Polynomials, my favorite! Alright I gotcha, with this you’re going to take each on of the problems into sections. For example: (x3 + 4x^2) is 9. You’ll do that with each one of the problems, so the answer here would be G
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:

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

For this problem, we have that:
G(F(x)) = x² + 4.
Which is possible with option D, as:
