Assume that y varies directly with

Galina-37 [17]

Answer:

x = 4/3

Step-by-step explanation:

Direct variation:

y = kx

We use the given x-y point to find k.

6 = k * 2/3

k = 6 * 3/2

k = 9

The equation is

y = 9x

For y = 12,

12 = 9x

x = 12/9

x = 4/3

a circle has a center at (3,5) the point (3,8) is on the circle what is the circumference of the circle to the nearest tenth of

kogti [31]

You need to use the distance formula to find the radius of the circle.

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2} \\ \\ d = \sqrt{(3-3)^2 + (8-5)^2} \\ \\ d = \sqrt{0^2+3^2} \\ \\ d = \sqrt{9} = 3$

The radius is 3.

The circumference is $2 \pi r$

$= 6\pi \\ \\ =18.8$

Find the distance, in feet, a particle travels in its first 2 seconds of travel, if it moves according to the velocity equation

just olya [345]

Answer:

The particle will travel 6 feet in first 2 seconds.

Step-by-step explanation:

We have been given that a particle moves according to the velocity equation $v(t)= 6t^2-18t+12$ . We are asked to find the distance that the particle will travel in its first 2 seconds.
