Write the equation of the circle graphed below

Mathematics
1 answer:
Norma-Jean [14]3 years ago
6 0

Answer:

The equation of the circle is

(x + 2)² + (y + 2)² = 9

Centered at (-2, -2), with radius of 3 units.

Step-by-step explanation:

The general equation of a circle is given as

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle, and r is the radius.

Looking at the graph, the center is the red dot. It corresponds to -2 on the y-axis, and -2 on the x-axis. So, the center (h, k) is (-2, -2).

The radius is the distance from the center of the circle to the edge of the circle. The red dot is the edge of the circle, there are 3 lines that represent 3 units, so we have a radius of 3 units.

Using these in the general equation, we have

[x - (-2)]² + [y - (-2)]² = 3²

(x + 2)² + (y + 2)² = 9

And this is the equation.

statuscvo [17]

Answer:

395149.22 cubic inches.

Step-by-step explanation:

The volume of a tank with length (L), width (W) and height (H) is given by

V = LWH ........ (1)

Now, the interior dimensions of a tank are 82.5 inches long, 58.5  inches wide, and 81.875 inches tall.

So, L = 82.5 inches, W = 58.5 inches and H = 81.875 inches.

Therefore, V = (82.5 × 58.5 × 81.875) = 395149.22 cubic inches.

Hence, the approximate volume of the tank is 395149.22 cubic inches. (Answer)

Simplify.
WITCHER [35]

Answer:

20x + 22

Step-by-step explanation:

34- 4x + 12x -12 +12x

step 1: 34 - 12 = 22

now you have left: -4x + 12x +12x

step 2: 12x +12x = 24x

step 3: 24x - 4x = 20x

Now you will combine the two answers you got: 20x +22

Hope this helps :)
