The rate of interest is 13%.
Step-by-step explanation:
Given,
Principal (P) = $560
Interest (I) = $145.60
Time (T) = 2 years
To find the rate of interest
Formula
If P principal was invested for T years at r% simple interest, the interest will be I =
So,
Putting the values of P, I, T we get,
145.60 =
or, r =
or, r = 13%
Hence,
The rate of interest is 13%.
It's asking for a composition function where you insert the function g(x) into f(x).
f(g(x))=10(x+8)+25
f(g(x))=10x+80+25
f(g(x))=10x+105
I believe the answer is 1.29+(0.75x)=7.00 hope i helped
