Find the rectangular coordinates of the point with the polar coordinates (8, 3 divided by 2 pi ). (1 point) (0, -8) (0, 8) (8, 0
jolli1 [7]

Answer:

(x,y) = (0,-8)

Step-by-step explanation:

We know that a point in polar coordinates is represented by

(r, θ)

Where r is the distance from the origin and θ is the angle.

Rectangular coordinates can be found by

x = r*cos(θ)

y = r*sin (θ)

x = r*cos(θ) = 8* cos (3π/2)

y = r*sin (θ) = 8 sin(3π/2)

x = 8* cos (3π/2) = 8*0 = 0

y = 8* sin (3π/2) = 8*(-1) = -8

(x,y) = (0,-8)

I really help with this ill mark u brainliest pls
erma4kov [3.2K]

Answer:

m\angle XYW  = (155 - 20x)\degree

Step-by-step explanation:

m\angle XYZ= m\angle XYW +m\angle WYZ\\\\150\degree = m\angle XYW +(20x-5)\degree \\\\150\degree - (20x-5)\degree = m\angle XYW  \\\\(150 - 20x+5)\degree = m\angle XYW  \\\\(155 - 20x)\degree = m\angle XYW  \\\\m\angle XYW  = (155 - 20x)\degree \\\\

Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equatio
natita [175]

Answer:

The equation, y=3 x,

Step-by-step explanation:

y=Distance traveled

x =Total time

Also, in terms of straight line

Slope =3= uniform Velocity

Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit, and 15 unit=Distance traveled in 5 (Unit of time).

→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
