Answer:
(4,2)
Step-by-step explanation:
It's parallel, so all of them have to be on the same way.
The last point has to be at the same distance from the one right above it
Answer: 45
Step-by-step explanation:
The rectangle is: 7 * 5
The triangle is: (4 * 5)/2
7 * 5 = 35
4 * 5 = 20
20/2 = 10
10 + 35 = 45
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
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= (4x² - 6) - (x² - 4x - 8)
= 4x² - 6 - x² + 4x + 8
= 3x² + 4x + 2. (B)
