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.

Jill, Meg, and Beth are sisters. Jill is 4 years younger than Meg. Enter an algebraic expression based on this situation. Let m

Murljashka [212]

Lets say

Jill=J

Meg=m

Beth=b

Jill is 4 years younger than meg so j+4=m

This is because if you add 4 to Jill's age, her age is going to be Megs age

Hope this helps and a brainliest would be appreciated

A spherical tank has a capacity of 800 gallons. Using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (t

nydimaria [60]

Solution-

Capacity of the spherical tank = 800 gallons.

1 gallon = 0.1337 ft³,

Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³

Formula for the volume of sphere

$V =\frac{4\pi r^{3}}{3}$

Equating both the volumes

⇒ $\frac{4\pi r^{3}}{3}$ = 106.96

⇒ $r^{3}$ = 25.53

⇒ $r = \sqrt[3]{25.53}$

⇒ r = 2.94

∴ Radius of the sphere is 2.94 ft

1. Kayla wants to find the width, AB, of a river. She walks along the edge of the river 100 ft and marks point C. Then she walks

Zolol [24]

You are given Kayla's walking distance along the edge of the river 100 ft and marks point C, then she walks 100 ft further and marks point D and she turns 90° and walks until her location, point A, and point C are collinear. She marks point E at this location. ABC and EDC are congruent. thats just what i think it is tho
