Answer:
90
Step-by-step explanation:
g(-10) = (-10)²+(-10)
= 100-10 = 90
Area is equal to length times width. The perimeter (the amount of rope) has to equal twice the length added to twice the width so we're left with:
A = l * w
200 = 2l + 2w
solve for either l or w
l = 100 - w
plug into the area equation to get one equation with two variables
A = w(100 - w)
A = -w^2 + 100w
take the derivative
A' = -2w + 100
set the derivative equal to zero
0 = -2w + 100
2w = 100
w = 50
This is the width that maximizes the area
with a width of 50, the length must also be 50 to have a perimeter of 200
therefore, they can rope up to 50 * 50 = 2500 ft^2
Answer:
B
Step-by-step explanation:
The Central Limit Theorem (something to look up!) says as the sample size increases, the sample mean approaches the population mean.
Answer:
20%
Step-by-step explanation:
1000/1250=0.8
1000 is 80% of the original price
therefore the percentage loss is 20%
