Answer:
8:28
Step-by-step explanation:
7+2 = 9
36/9 = 4
4 x 2 = 8
7 x 4 = 28
8:28
Is this what you are asking?
Yay, derivitives
I'mma ignore that x is the shorter side because I don't know which one has to be shorter yet
we need to find the max area
but with 3 sides
area=LW
let's say the sides are z and y
zy=area
and the relatiionship between them is
hmm,
z+2y=1200
because one side has no fencing
so
z+2y=1200
solve for z
z=1200-2y
sub for z in other
(1200-2y)(y)=area
expand
1200y-2y²=area
take derivitive
1200-4y=dy/dx area
max is where dy/dx goes from positive to negative
solve for where dy/dx=0
1200-4y=0
1200=4y
300=y
at y<300, dy/dx<0
at y>300, dy/dx>0
so at y=300, that is the max
then
z=1200-2y
z=1200-2(300)
z=1200-600
z=600
so then
z=600
y=300
300<600
so the shorter side would be y
so then we see our choices and noticed that
erm
I think it is f(x)=1200x-2x²
takind the derivitive yeilds none of the others
so ya, you are right
Hey!
--------------------------------
Solution #1:
x - 12 = 4
x + (-12) = 4
x + (-12) + 12 = 4 + 12
x = 16 ✔
--------------------------------
Solution #2:
x - 1/2 = 4
x + (-1/2) = 4
x + (-1/2) + 1/2 = 4 + 1/2
x = 4 1/2 ✔
--------------------------------
Solution #3:
x - 1.2 = 4
x + (-1.2) = 4
x + (-1.2) + 1.2 = 4 + 1.2
x = 5.2 ✔
--------------------------------
Hope This Helped! Good Luck!
