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

Mathematics
1 answer:
Rus_ich [418]2 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.

A recipe calls for 1 cup of ground almonds. How many ounces of ground almonds should you use for this recipe if 1 pint of ground
aleksley [76]

Answer: There are 3.36 ounces of ground almonds in 1 cup.

Step-by-step explanation:

Since we have given that

1 pint = 0.42 pounds

As we know that

1 cup = 0.5 pints

1 pound = 16 ounces

So, We need to find the number of ounces.

As 1 pint = 0.42 pounds = 0.42 × 16 = 6.72 ounces

0.5 pints is given by

6.72\times 0.5\\\\=3.36\ ounces

Hence, there are 3.36 ounces of ground almonds in 1 cup.

Round 3184.5641 to the nearest hundred
Sonja [21]
When you round you have to check the number to the right of the number you are rounding. If the number to the right is 0-4 then you keep the number the same. 5-9 the number you are rounding goes up by one. Now the 4 before the decimal point is in the ones spot. The 5 to the right of the 4 is the tenth spot and the 6 to the right of that is in the hundredth spot. so this is where we need to round. To the right of the 6 is a 4 so the number would stay the same. Now when you round you drop all the numbers after it so the number is 3184.56
