To answer this question you should know what to do to change the polar coordinates to rectangular ones: x = rcos (θ)
y = rsen (θ)
So for r = -2 and θ = 2π we have
x = -2cos (2π)
x = -2
y = -2sen (2π)
y = 0
Finally the equivalent point in Cartesian coordinates is the point:
(-2 0)
The correct answer is option B
Answer:
Step-by-step explanation:
You can find the value of "c" that will make it a perfect square trinomial by Completing the square.
Given the following expression provided in the exercise:
You can notice that it is written in this form:
Then, you can identify that the coefficient "b" is:
Since to complete the square you must add and subtract the half of square of coefficient "b", you can conclude that:
Therefore, substituting "b" into , you get:
