Answer:x=1 y=2
Step-by-step explanation:
you add and get 8x=8 x=1 so plugging in one you get 5+2y=9 so 4=2y so y=2
C=2π√150 ft
Or, C≈76.95 ft
Comment if you want to see how I did this.
T = 2
To find this, follow these steps.
First, you need to find g(2):
t-1
2-1
1
Therefore 1 is your first answer. Then you input that answer into h(t).
2(t) - 2
2(2) - 2
4 - 2
2
Thus, 2 is your final answer.
Hope this helps!

I believe but I am not too sure.
