The polar coordinates of the point whose cartesian coordinates is (-2√3 , 2) is (4cos210, 4sin210)
<h3>Polar form of a rectangular coordinate</h3>
The polar form of a rectangular coordinate (x, y) is expressed as (rcos theta, r sin theta)
Given the coordinate (-2√3 , 2)
r = √(-2√3)²+2²
r = √12+4
r = 4
theta = tan^-1(-2/2√3)
theta = tan^-1(-1/√3)
theta = -30 degrees = 210 degrees
The polar coordinates of the point whose cartesian coordinates is (-2√3 , 2) is (4cos210, 4sin210)

Answer:
r in terms of p is 15/p , and when p is -5 than x = - 3
<h3>Answer: 10</h3>
=======================================================
Explanation:
We'll start off converting each mixed number into an improper fraction.
The formula to use is 
So,
And,
So the task of computing 
is exactly the same as computing 
Notice how we have an 8 up top and an 8 down below. Those 8's cancel out and we're left with 
. That fraction does not reduce any further.
The last step is to convert that improper fraction result to a mixed number.
Or you could note that 17/3 leads to 5 remainder 2. The 5 is the whole part and the 2 forms the numerator of the fractional part 2/3.
The value is in 
form where
Therefore, A+b+c = 5+2+3 = 10
You are correct with that answer
Answer:
150
Step-by-step explanation:
200 divided by 8 = 25 each
25 x 6 = 150
