12.57
Step-by-step explanation:
Answer:
Maximum area possible
f(max) = 3906,25 ft²
Dimensions:
a = 62,5 ft
w = 62,5 ft
Step-by-step explanation:
Perimeter of the rectangular fencing P = 250 feet
And sides of the rectangle a and w (width of rectangle)
Then
A = a*w
2a + 2w = 250 ⇒ a = (250 -2w)/ 2 ⇒ a = 125 - w
f(w) = (125 - w ) *w f(w) = 125w - w²
Taking derivatives both sides of the equation
f´(w) = 125 - 2w f´(w) = 0 125 - 2w = 0
w = 125/2
w = 62,5 ft ⇒ a = 125 - 62,5
a = 62,5 ft
f(max) = ( 62,5)²
f(max) = 3906,25 ft²
Answer:
$77.44
Step-by-step explanation:
If the shoes cost $88 but you get a 20% discount, subtract 20% from 88: -->
$88-20% = $70.4
Then add 8% of 88 to 70.4 -->
8% of $88 = $7.04.
$70.4 + $7.04 = $77.44
Therefore the final price of the shoes are $77.44
Hope this helps!!!~~ <3
