Answer:
0.286
Hope that helps!
Step-by-step explanation:
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
y = 2x + 4
in standard form is
2x - y = -4
Second equation is
x + 2y = 8
Those aren't parallel.
Answer: exactly one solution
Let's solve,
x +2(2x + 4) = 8
5x + 8 = 8
5x = 0
x = 0
y = 2x + 4 = 4
Solution is (0,4)
Answer:
1+b/a
Step-by-step explanation:
To find the amount of a/b we have to solve the equation
(a+b)/a
a/a+b/a
a/a is one so
1+b/a
