So here is how we find the answer to this given problem.
<span>The formula for area is: A=(l)(w)
So, A=(2x)(8-x²)
A=16x-2x³
dA/dx = 16-6x²
then you will use calculus to get the absolute local maximum of x
by letting dA/dx = 0
then wha you will get is x = 2sqrt(6)/3
so the area would be= 64 * sqrt(6) / 9
</span>or 64√<span><span>6/</span>9.
Based on the choices given, the answer would be option D.
Hope this answer helps.</span>
Answer:
B
Step-by-step explanation:
Minimum L = 45
Maximum L = 180
L(w) = 3w - 27
Therefore, when 45 = 3w - 27 ⇒ w = 24
when 180 = 3w - 27 ⇒ w = 69
So 24 ≤ w ≤ 69
Therefore, the answer is B
Answer:
13.2
Step-by-step explanation:
40 decreased by 33% = 26.8
Absolute change (actual difference):
26.8 - 40 = - 13.2
Answer:
The temperature changed by 7°F each day.
Step-by-step explanation:
<em>The temperature changed a total of 42 degrees throughout the six days, dividing it into 7 degrees for each day.</em>
