Answer:
(x,y) = (0,-8)
Step-by-step explanation:
We know that a point in polar coordinates is represented by
(r, θ)
Where r is the distance from the origin and θ is the angle.
Rectangular coordinates can be found by
x = r*cos(θ)
y = r*sin (θ)
x = r*cos(θ) = 8* cos (3π/2)
y = r*sin (θ) = 8 sin(3π/2)
x = 8* cos (3π/2) = 8*0 = 0
y = 8* sin (3π/2) = 8*(-1) = -8
(x,y) = (0,-8)
Answer:
Step-by-step explanation:
To solve this problem we first need to find the diameter of the circle. We are told the point 
is the circle, so we can assume it is the center of the circle. To find the diameter we can use the Pythagorean Theorem:
The diameter is 
units, which means the radius is 
. From here we can calculate the area of the circle:
Now we need to subtract the area of the triangle from the area of the circle. Calculate the area of the triangle:
Subtract the triangle area from the circle area to get the area of the shaded area:
A) $675
b) $202.50
Multiply $13.50 by the total number hours worked each week during each season
