Because we are finding the lowest point of the rope we have to minimize the equation h=0.01x2-x+27<span>. We first have to find the derivative of the equation which would be h’=0.02x-1 then find the value of x when h’=0, which is x=50. Using this value to substitute for x in the original equation, we find that the lowest point of the rope is only 2 inches above ground.</span>

Answer of this question is in the picture .
The answer is 1 day because if it takes Doug 3 days by himself and if his son helps him and it takes 2 days with the both of them that means it would only take Doug's son 1 day.
Answer:
$41000
Step-by-step explanation:
If her salary was $1,000 more than the previous year and she save $4,200, $4,200 was 10% of her salary. So we should create an equation. (x being her salary from the previous year)
0.1(x+1000)=4200 (divide 4200 by .01)
x+100=42000
42000-1000= 41000
Answer:
B.x>-17
Step-by-step explanation:
1. Divide both sides by -4:
-4x/-4<68/-4
2.< will change to > since you are dividing by negative
3.your final answer will be x>-17
