Perimeter = 24
triangle perimeter = 2W + 2L
24= 2W + 2L
12 = W + L
L= 12-W
AREA = W*L
AREA = (W)(12-W)
A = 12W-W^2
maximum occurs when you take the derivative
d/dw=12-2w = 0
w=6
after this i think we can say 6 * 6 = 36 is the maximum area.. not to sure, havent done a problem like this in a while
hope this helps
or if we know what w=6 we can find L
L = 12-w which we still get 6<span />
Answer:
1. c 2. a 3. b
Step-by-step explanation:
1/4 divided by 3
3/1 would become 1/3 because you changed from division to multiplication
1/4 times 1/3= 1/12

Y=Ф + 8/(ФcosФ) ==> note that
dy/dФ = 1 - 8/[(ФcosФ)]² x (-8sinФ) ==> dy/dФ = 1+[(64sinФ)/Фcos²Ф]
==> dy/dФ = 1+ 64tanФ/Ф or dy/dФ = (Ф+tanФ)/Ф
Answer: m=4/7x
Step-by-step explanation:
First, you need to use the equation y2-y1/x2-x1
Plug that in and you get 2-6/-3-4
2-6= -4
-3-4=-7
Cancel out the negatives
And the answer is 4/7
