Answer:
x^2+y^2 = 3^2
Step-by-step explanation:
We need to eliminate the parameter t
Given:
x = 3 cos t
y = 3 sin t
Squaring the above both equations
(x)^2=(3 cos t)^2
(y)^2 =(3 sin t)^2
x^2 = 3^2 cos^2t
y^2=3^2 sin^2t
Now adding both equations
x^2+y^2=3^2 cos^2t+3^2 sin^2t
Taking 3^2 common
x^2+y^2=3^2 (cos^2t+sin^2t)
We know that cos^2t+sin^2t = 1
so, putting the value
x^2+y^2=3^2(1)
x^2+y^2 = 3^2
Hence the parameter t is eliminated.

Answer:
republicans
Step-by-step explanation:
Given, there are 60% democrats and republicans 40%
60% of the democrats voted for democrats and 95% of the republican voted for their candidate
therefore
% of votes that went for Democrats =0.6*0.6=0.36
= 36%
% of votes that went for Republics=0.4*0.95=0.38
= 38%
Since the republicans have more % of votes thus Republic's mayor runs city hall.
