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)

On a rectangular soccer field, Sang is standing on the goal line 20 yards from the corner post. Jazmin is standing 99 yards from
Anna007 [38]
Okay, so Sang is standing 20 yards away from one corner, and Jazmin is standing 99 yards away from the same corner. If this is a rectangle (I like visuals, so I'll use them to explain), then:
               
                    99ft
      A  -------------------------  B
         |                              |
20 ft  |                              |
         |                              |
    C   --------------------------  D

The question is asking you to solve for the diagonal line between points C and B. If you imagine a line there, you actually have the rectangle split into two triangles. So if you have triangle ABC, side CB would be the longest line, or the hypotenuse. That means you can use the Pythagorean Theorem to solve the problem.

A^2 + B^2 = C^2
99^2 + 20^2 = C^2
9,801 + 400 = C^2
10,201 = C^2

Now you solve for the square root of 10,201 to get C.

sqr (10,201) = C
C = 101 yards

3) What is the measurement of each side if the perimeter is 78?<br> (3x - 4) cm<br> (2x + 3) cm
Goshia [24]
There are 4 sides so add 4 sides
3x-4+3x-4+2x+3+2x+3=78

Combine like terms
10x-2=78

Add 2 to each side of the equation
10x=80

Divide by 10
X=8

Enter x into equation
3(8)-4=20
2(8)+3=19

Multiply by 2
20 x 2= 40
19 x 2 = 38
40 +38 =78

Side 1- 20
Side 2- 19
Side 3- 20
Side 4- 19
