How many times would a member and a non member have to rent a boat in order to pay the same amount
Yakvenalex [24]
X = number of times they rent a boat. 

Members 
Cost = 105 + 9.50x
Non-members because members don't have to pay the 105 so we gotta leave it out. 
Cost = 14.75x 

Now to determine whether the cost would be equal, we need to set the two equations equal to each other.

105 + 9.50x = 14.75x 

Now solve for x

105 = 5.25x
 
20 = x 

<span>That's your answer.</span><span> They would have to rent 20 times to equal each other. </span>

Convert rectangular equation to polar equation calculator
algol13
To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.
r= \sqrt{x^2+y^2}
and θ is given by the arctan of the ratio of y to x.
\theta=\tan^{-1} \frac{y}{x}
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
r= \sqrt{3^2+4^2} = \sqrt{9+16} = \sqrt{25} =5 \\ \theta=\tan^{-1}( \frac{4}{3}) =53.13^o
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
