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.

Answer:
cos (theta) = √21/5
Step-by-step explanation:
sin (theta) = 2/5
(sin (theta))^2 = 4/25
4/25 + (cos (theta))^2 = 1
(cos (theta))^2 = 1 - 4/25 = 21/25
cos (theta) = √21/5
