Answer:
18.84
Step-by-step explanation:
2
r/2 is the circumference of half a circle. The radius is 6.
2(3.14)(6)/2 = 18.84
7 out of 16 . so therefore you add the number of oranges and pairs then on the number 16 you just add all pieces of friut
So first we solve for y in second equation
3x+y=4
y=4-3x
sub for y in first equiton
2x-(4-3x)^2=1
2x-(16-12x-12x+9x^2)=1
2x-(16-24x+9x^2)=1
2x-16+24x-9x^2=1
-9x^2+26x-16=1
times -1 both sides
9x^2-26x+16=-1
add 1 to both sides
9x^2-26x+17=0
factor
(x-1)(9x-17)=0
set each to zero
x-1=0
x=1
9x-17=0
9x=17
x=17/9
so sub back to find y
y=4-3x
y=4-3(1)
y=4-3
y=1
(1,1)
y=4-3x
y=4-3(17/9)
y=4-17/3
y=12/3-17/3
y=-5/3
(17/9,-5/3)
the 2 intersection points are
(1,1) and
Width = xlength = 4x Use the formula for the perimeter of a rectangle to solve for x: perimeter = 2(length) + 2(width)50 = 2(4x) + 2(x)50 = 8x + 2x50 = 10x5 = x The width (x) is 5 feet and the length (4x) is 20 feet.
It increases linearly, since it increases by about the same amount every month.
