What are the Cartesian coordinates of a point with polar coordinates (17, 60 degrees)?

Mathematics

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.

-6 + -8 10 points plz help
satela [25.4K]

Answer

The answer is negative 14.

Step-by-step explanation:

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

Anettt [7]

Answer:

D) y = 27 · (3)^x

Step-by-step explanation:

Replace x with the x values.

27 · (3)^-2 = 27 · 1/9 = 3

27 · (3)^-1 = 27 · 1/3 = 9

27 · (3)^0 = 27 · 1 = 27

27 · (3)^1 = 27 · 3 = 81

17 · (3)^2 = 27 · 9 = 243

D is your answer.

Hope this helps

guajiro [1.7K]
If he spends 1/4 reading the news, then he spends 3/4 reading the other stuff

3/4 * 8/9 = 24/36 = 2/3 of an hr ...time spent reading sports and comics

(2/3) / 2 =
2/3 * 1/2 = 2/6 reduces to 1/3....so he spends 1/3 of an hour (or 20 minutes) reading the comics
