Answer: (fоg)(24)=5
Step-by-step explanation:
(fоg)(24) is f of g of 24. This means you plug in g(24) into f(x).
Now that we know g(24), we can plug it into f(x).
f(4)=2(4)-3
f(4)=8-3
f(4)=5

Answer:
2.25%
Step-by-step explanation:
I = Prt
Given:
I = 540
P = 8000
t = 3
Solve for r:
I = Prt
r = I/(Pt)
r = 540/(8000 * 3)
r = 540/24000
r = 0.0225
Rate in percentage form:
0.0225 * 100 = 2.25%
