Answer:a
Step-by-step explanation:
Because sum means addition
Average speed
Average speed between the checkpoints
distance between the checkpoints
divided by
time between the checkpoints.
Distance between the checkpoints =
(mileage at B) minus (mileage at A)
=(208)-(120) = 88 miles .
Time between the checkpoints =
time at - time at A
=(3:00 PM) - (1:00 PM) = 2 hours .
Average speed between the checkpoints =
(88 miles) / (2 hours)
=44 miles per hour .
Answer:
Answer: d 12x^3 + 3
Step-by-step explanation:
This is a composite function. Just insert g(x) into the x of f(x)
f(x) = 3x
3(4x^2 + 1)
Distribute the three
3(4x^2 + 1)
12x^3 + 3
Answer:
15.5^2 + 14.0^ = 20.8^2
436.25 = 432.64
it is not a triangle because a+b is not = c
