Express the polar coordinates (2,3pi/4) as Cartesian coordinates

Mathematics
1 answer:
Rus_ich [418]3 years ago
8 0

The Cartesian equivalent of the polar coordinates (r, theta) is

(r cos t, r sin t), where t = theta.

So, (2, 3pi/4) becomes

(2 cos(3pi/4), 2 sin(3pi/4))

(2 • -sqrt{2}/2, 2 • sqrt{2}/2)

Answer: (-sqrt{2}, sqrt{2})

Done.

Note: sqrt = square root for short.

How do you solve this??
DochEvi [55]

Answer:

Step-by-step explanation:

Hi Millie.

First we can realize that the number of cubes of each type does not matter, only the ratios between them. We see that if there are x yellow cubes, there are 3x blue cubes. And therefore, there are 5*3x green cubes, or 15x green cubes. This means that the cubes are in a 1:3:15 ratio, or that for every 1 yellow cube, there are 3 blue and 15 green cubes.

Now we can find the probability of picking a yellow cube. Since there are 18 non-yellow cubes for every yellow cube, this means that there is a 1/19 possibility of picking a yellow cube.
