Area as a function of width, w is:
a(w)=(w-25)^2+625
for maximum area, the width will be:
a'(w)=2(w-25)+0=0
solving for w we egt
2w-50=0
2w=50
w=25 m
given that the perimeter is 100, the length will be:
100=2(L+W)
solving for L we get:
L=50-W
but W=25m
hence
L=50-25=25 m
thus the maximum area will be:
A=L*W=25*25=625m^2
480? I mean she burned as many as Monday and Monday she burned 480..
Answer:
28.35
Step-by-step explanation:
10 percent of 31.5 = 3.15
31.5
-3.15
-------------
28.35
Yes it should bring it up to a C or maybe it will be a 70 or 75
2 x 2 + 9x + 8 = 0
4 + 9x + 8 = 0
12 + 9x = 0 (subtract 12 from each side)
9x = -12 (divide by 9 on each side)
x = -12/9
