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:
25/42 mi
Step-by-step explanation:
5/6 of 5/7 of a mile is ...
(5/6)(5/7 mi) = 25/42 mi
Both a rhombus and a rectangle have diagonals that are perpendicular bisectors, but the ones formed in a square are all congruent, so that is probably the most descriptive one.
Answer:
x = 13
Step-by-step explanation:
The sum of the exterior angles of a 4 sided polygon is 360
139+ 6x+9x+2x = 360
Combine like terms
139+17x=360
Subtract 139 from each side
17x = 360-139
17x = 221
Divide each side by 17
17x/17 = 221/17
x = 13
hello
so this equation is written in point slope form: 
we can solve for y to get the equation into slope intercept form: y=mx+b
y+1=4/3x
subtract 1 from both sides
y=4/3x-1
slope: 4/3
y-intercept: -1
hope this helps
have a nice day :)
