Find the Cartesian coordinates of the given polar coordinates. Then plot the point. (a) (2, π) (x, y) = WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot ((b) (4, −2π/3) (x, y) = WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot (c) (−4, 3π/4) (x, y) = WebAssign Plot WebAssign Plot WebAssign Plot WebAssign Plot

(a) ∴(x,y)= (-2,0)

(b) ∴(x,y)= (-2,)

(c) ∴(x,y)=

Step-by-step explanation:

To convert from polar coordinate to Cartesian Coordinate(x,y)

x = r cos θy = r sin θ

(a)

Here r = 2 and θ = π

x= 2 cos π = -2

y=  2 sin π =  0

∴(x,y)= (-2,0)

(b)

Here r = 4 and

x= 4 cos   = - 2

y=  4 sin   =

∴(x,y)= (-2,)

(c)

Here r= -4  and

∴(x,y)=

It seems its starts out increasing by 10 + 1. However each year it adds 1 more so for year three for example it would be 121 + 12 instead of 11 for the simple fact it increases +1 every year. So in conclusion for the rest of the trucks per year would increase by 10+ ? depending on which year. 

Year 3 +12 =133 
Year 4 +13 =146
Year 5 +14 =160
Year 6 +15 =175
Year 7 +16 =191
Year 8 +17 =208
Year 9 +18 =226

And so on. :)
