Answer:
Part A
5yr old boy.
Y=-(1/8)x+113/8 x=5
Y=-5/8+113/8=(113-5)/8=108/8
Y=13.5 hrs
Yes the estimated value of sleep by this function is reasonable as it is close to childhood more sleep is likely.
Part B
20yr old boy.
Y=-(1/8)x+113/8 x=20
Y=-20/8+113/8=(113-20)/8=93/8
Y=11.63 hrs
No the estimated value of sleep by this function is not reasonable as the normal sleep of 7-8 hrs is enough for adults.

Step-by-step explanation:
Here, we want to write 26 * 26^8 in exponential form.
26* 26^8 is same as 26^1 * 26^8
According to the first law of indices, we are going to add the powers together;
Thus, this gives ; 26^(1 + 8) = 26^9
