Substitute x = 0 to the equation of the function:

Answer:
H (36 / 5)
Divide each of the numbers and see which one is closest to seven
If m1 and m2 are the slopes of each line, for them to be perpendicular you gotta solve
m1 * m2 = -1
Answer:

Step-by-step explanation:
You can think of this as adding the area of the rectangular portion of the deck (length x width) and the semicircular portion (πr^2)/2.
(l×w)+(πr^2)/2
(10×7)+((π2^2)/2
79+2π

I believe the answer is 60%
