Can someone please help me, thank you.

Find the rectangular coordinates of (9,150).

Step-by-step explanation:

The rectangular representation of the polar point

(9,150) is

(−9√32,92)

(9,150)

Step-by-step explanation:

Use the conversion formulas to convert from polar coordinates to rectangular coordinates.

x = rcosθ

y = rsinθ

Substitute in the known values of r = 9 and θ = 150 into the formulas.

(9) cos (150)

y = (9) cos (150)

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant.

x = 9 (-cos (30))

y = (9) sin (150)

The exact value of cos (30) is √3/2.

x = 9 (-√3/2)

y = (9) sin (150)

Multiply 9 (-√3/2)

x = -9√3/2

y = (9) sin (150)

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

x = -9√3/2

y =9(sin)30

The exact value of sin (30) is ½

x = -9√3/2

y = 9 (½)

Combine 9 and ½

x = -9√3/2

y = 9/2

The rectangular representation of the polar point (9,150) is (−9√3/2, 9/2)

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

answer: a.   one is a factor of every whole number since every number is divisible by itself.
