Answer:
Step-by-step explanation:
Given that a curve in polar coordinates is given by:
r=9+3cosθ
a) At point P, we have

Substitute to get

b) Cartesian coordinate is

c) At the origin r =0
when r =0
we have

Since cos cannot take values as -3 it doe snot pass through origin.
Answer:
Step-by-step explanation:
let present age of
Dylan=x
Renee=y
x+y=57
9 years ago
x-9=2(y-9)=2y-18
x=2y-18+9=2y-9
so 2y-9+y=57
3y=57+9=66
y=66/3=22
x+22=57
x=57-22=35
Dylan's present age=35 years
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3
n^-6 * n^3 = n^-3
If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.
n^-3 = n^-3 / 1 = 1/n^3
when the factor moves to the other side of the fraction, the side of the exponent changes.
Answer:
30in squared
Step-by-step explanation:
(4x5) + ((4x3)/2) + ((4x2)/2) = 20 in sq.
