Answer:
47 feet per second
Step-by-step explanation:
35+(40X5)=235
235/5=47 feet per second
(47 feet per second is aproximately 32 mph.)
The answer is D) 5 and 5/8ths because 2 1/2 + 3 3/4 + 4 1/8
= 10 3/8
10 3/8 + 5 5/8 = 16
The function would be f(x) = 40x + 4.
It's plus 4 because it starts counting after the 4 kilometers already happened.
It's 40x because that's the rate of change (km/h) and the x represents the hours.
f(x) basically means y, but in functions you use f(x).
Hope this helps :)
