To solve the problem you must know that to change from Cartesian to polar coordinates you must write:
x = rcos (θ)
Where "r" is the radius
Likewise y = rsin (θ)
Therefore, in the expression r = 3cos (θ) one can write r as:
r = x / cos (θ)
So:
x / cos (θ) = 3cos (θ)
x = 3cos ^ 2 (θ)
The same for y ...
y = rsin (θ)
y = 3cos (θ) sin (θ).
Finally the correct answer is option 2.
x = 3cos ^ 2 (θ) y = 3cos (θ) sin (θ).
Answer:
60 books
Step-by-step explanation:
1/4+1/3+1/6=3/4
Since 15 is 1/4 of the total, all you have to do is multiply it by 4, giving you 60 books.

On Monday, a museum had 200 visitors. On Tuesday, it had 340 visitors. Estimate the percent change
in the number of visitors to the museum. Use pencil and paper. Estimate how many people would
have to visit the museum on Wednesday to have the same estimated percent change between
Tuesday and Wednesday as between Monday and Tuesday. Explain your answer.
Which of these is the best estimate for the percent change in the number of visitors to the museum?
OA. 75% increase
B. 50% decrease
OC. 1100 decrease
OD. 25% increase
Answer 1100 + 25 -400 ÷500
