0.246 can be written as 246/1000
246/1000 simplifies into 123/500

Plug the number 2 into the equation.
4(2+2)+5
4*4+5
16+5

So you want to add together 4, 6, 11, and 9.
So to make it easier, I would first add together 4 and 6, and 11 and 9.
4 and 6 added together is 10
11 and 9 added together is 20
So, just 20 + 10, or 30.
Answer:
C. (8.5, 14.72)
Step-by-step explanation:
You can translate the coordinates using ...
(x, y) = (r·cos(θ), r·sin(θ))
Filling in the given polar coordinates, (r, θ) = (17, 60°), we have ...
(x, y) = (17·cos(60°), 17·sin(60°)
(x, y) = (8.5, 14.72)

If you sketch the vector, you realize that the short side of the triangle (the x-coordinate) is half the length of the hypotenuse (17). This is because you recognize the side-length relationships in a 30°-60°-90° triangle. Only one answer choice shows that value.
