y=2(cos(50=90n)=isin(50+90n))
take n=0 ,y=2(cos(50)+isin(50))
take n=1,y=2(cos(140)+ isin (140))
take n=2,y=2(cos(230)+ isin (230))
take n=3,y=2(cos(320)+isin(320))
The slope is already given in the question, so we only ned to solve for the y-intercept using y = mx + b.
4 = 3(1) + b
4 = 3 + b
4 - 3 = 3 + b - 3
1 = b
Now, write the equation in slope-intercept form.
y = 3x + 1

50:40=x:35
5/4=x/35
times both sides by (4*35)
5*35=4x
175=4x
divide both sides by 4
43.75=x
costs $43.75
