Answer:
16/5 is equal to 3 1/5. So I guess the answer is 3 1/5 per hour. Forgive me if I din't understand the question
Step-by-step explanation:
3. g(x) = (x+2)/ |x+2| the denominator cannot be 0
|x+2| cannot be 0
x cannot equal -2
Domain all real numbers but -2
g(-1) = (-1+2)/ |-1+2| = 1/|1| = 1
4. h(x) = (x-4)/(x^2+5x-36)
factor the denominator
h(x) = (x-4)/(x+9) (x-4) the denominator cannot be zero do not cancel, this is a hole
x+9 cannot equal zero so x cannot equal -9
x-4 cannot equal 0 so x cannot equal 4
Domain all real numbers but -9 and 4
h(-1) = (-1-4)/((-1)^2+5(-1)-36) = -5/(1-5-36) = -5/-40 = 1/8
11 7/8 feet is the answer bc perimeter is just adding all the side, so if 2 side = 5 5/8 and the other 2 = 6 1/4 then the sum will be 11 7/8 feet
