Answer:
length = 100 m
width = 63.66 m
Step-by-step explanation:
Let's call
x: lenght of rectangle
y: width of rectangle, and also diameter of the semicircles
Perimeter: 2*x + π*y = 400
or:
x = 200 - π/2*y
Area of the rectangle = x*y
Replacing:
A = (200 - π/2*y)*y
A = 200*y - π/2*y²
At the maximum:
dA/dy = 200 - π*y = 0
y = 200/π
y = 63.66 m
and
x = 200 - π/2*63.66
x = 100 m
Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation. So remember to solve this problem, addition property of equality is adding from both sides of an equation to the same number doesn't change the equation.
First, add 3 from both sides.
Solve.
As a result, the correct answer is x=7.

Answer:
c
Step-by-step explanation:
y-6<0,y<6
all graphs satisfy it
y<x+4
when x=0,y<4
c satisfies it.
y+6>-3x
when x=0,y>-6
c satisfies it.
a b
c d
I cannot answer that, as I do not have the graph and need more info to answer.
