Answer:

(x +4)^2 +(y +8)^2 = 64

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

(x -h)^2 +(y -k)^2 = r^2

The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...

(x +4)^2 +(y +8)^2 = 64

Hoochie [10]

Answer:

B. 5√3 is your answer.

Step-by-step explanation:

This is an equilateral triangle, which means that all external sides (that make up the triangle) have the same measurement.

This means that line segment AC = 10.

Solve for the measurement of line segment AB. Line Segment AB is 1/2 of AC, making it: 10/2 = 5

Line AB = 5

Line AD = 10

This is a 1, √3, 2 triangle, in which:

1 = 5

2 = 10

Solve for √3. Multiply √3 with the 1:

5 x √3 = 5√3

B. 5√3 is your answer.

What is a linear equation in math?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

$\frac{3^{2} * 3^{-5} }{4^{2} } = \frac{3^{-3} }{4^{-2} }$

$\frac{1}{3^{3} }$ ÷ $\frac{1}{4^{2} }$

$\frac{1}{27} * 16 = \frac{16}{27}$
