Answer:
Step-by-step explanation:
(f ° g)(18) is another way of writing f(g(18)) which is telling you to evaluate function g at an x value of 18, then take that answer and plug it in for x in the function. Like this:
g(18) = 18 - 9 so
g(18) = 9. Now take that 9 and plug it into the f function in place of x:
f(9) = -8(9) + 8 and
f(9) = -72 + 8 so
f(9) = -64
Answer:
600 mph
Step-by-step explanation:
Given that,
Distance covered by ball, d = 5 miles
Time taken, t = 30 seconds
1 second = (1/3600) hour
Speed = distance/time

So, the speed of the ball is 600 mph.
Answer:
125
Step-by-step explanation:
There are four right angles in a triangle so i divided 500 by 4
(n-7) (n-7) will be your answer
n x n = n²
n x -7 = -7n
n x - 7 = -7n
-7n +(-7n) = -14n
-7 x -7 = 49
(n-7)² is your answer
