Take first derivative of area function and set it to zero
da/dx=24 - 2x=0
Now it is set to zero add -2x to both side
24 - 2x = 0
24 = 2x
Now divide by 2 in both sides
12 = Width
Your width now is 12
Plug 12 into you equation like this:
24 (12) - 12^2= A
288 - 144 = A
144 = Area
144 feets is the maximum area using the width 24
<span>A. cos(x) = cos(-x) [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph. [false]
C. cos(x) = -cos(x) [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin. [false]</span>
