Answer:
C 5a^2 +70a +240
Step-by-step explanation:
We have given these following functions:

h(a+4)
This function is:



f[h(a+4)]

Thus

The correct answer is given by option C.
To find the rate add 1 to the annual rate divided by 365 days raised to the number of days left in the year minus 1.
r= (1 + 0.2319/365)^305 - 1
r = 0.2138
Now multiply by 100 for the percent:
0.2138 x 100 = 21.38%
Answer:
