graph c
because the graph x = -2 is a vertical line at -2 on the x axis
The angle of rotation of a polygon is found using the formula 360/n
Where n is the number of sides.
Shape 1: 360 / 10 = 36
Shape 2: 360 /4 = 90
Shape 3: 360 /5 = 72
Shape 4: 360/8 = 45
Shape 5: 360/3 = 120
Shape 6: circles = 1
Shape 7: 360 /6 = 60
Shape 8: 360 / 12 = 30
There are 3 shapes that are 72 or higher.
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
By definition, the arc length is given by:
S = R * theta
Where,
Theta: central angle
R: radio
Substituting the values we have:
S = (1600) * (π / 8)
Rewriting we have:
S = 200π feet
S = 628.3185307 feet
Round to the nearest foot:
S = 628 feet
Answer:
The length of the curve to the nearest foot is 628 feet.
