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)

The solution to the given equation is x = -8
<h3>Solving Linear Equations</h3>
From the question, we are to determine value of x in the given equation
The given equation is
(x + 6)/x = 1/4
To solve the given equation, we would solve for the unknown variable x
(x + 6)/x = 1/4
First, multiply both sides of the equation by x
x + 6 = x × 1/4
x + 6 = x/4
Now, multiply both sides of the equation by 4
4(x + 6) = 4 × x/4
4x + 24 = x
Now, subtract x from both sides of the equation
4x - x + 24 = x - x
3x + 24 = 0
Subtract 24 from both sides of the equation
3x + 24 - 24 = 0 - 24
3x + 0 = -24
3x = -24
Divide both sides of the of the equation by 3
3x/3 = -24/3
x = -8
Hence, the solution to the given equation is x = -8

Answer:
(D) f(x+1)=2f(x)
Step-by-step explanation:
The sequence is:
Now,
On continuous calculation, we would discover that the next term is gotten from the preceding term by multiplying it by 2.
Therefore for term f(x), the next term f(x+1) is:
f(x+1)=2f(x)
