Which graph represents the polar curve r = 4cos(30)?
stepan [7]

The equation of the polar curve r = 4\cos(3\theta) is an even cosine function.

<h3>Polar curves</h3>

In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point

The equation of the polar curve is given as:

r = 4\cos(3\theta)

To graph the polar curve, we make use of the following representations:

  • r represents the y-axis
  • \theta represents the x-axis

Using the above representation, we can graph the polar curve

See attachment for the graph that represents r = 4\cos(3\theta)

Choose the equation that satisfies the data in the table.
Zanzabum

Answer:

B. y = \frac{2}{15} X + 2

Step-by-step explanation:

I. Given x = 15 and y = 4

         4 = \frac{2}{15}(15) + 2

         4 = 2+2

         4 = 4 true

II. Give x = 0 and y = 2

         2 = \frac{2}{15}(0) + 2

         2 = 0 + 2

         2 = 2 true

III. Given x = -15 and y = 0

         0 = \frac{2}{15}(-15) + 2

         0 = -2 + 2

        0 = 0 true

Good luck.

Solve the equation. Show your work. 3x – 10 = 5x + 32
liq [111]

Answer:

-21 =x

Step-by-step explanation:

3x – 10 = 5x + 32

Subtract 3x from each side

3x-3x – 10 = 5x-3x + 32

-10 =2x +32

Subtract 32 from each side

-10 -32 = 2x+32-32

-42 = 2x

Divide each side by 2

-42/2 = 2x/2

-21 =x
