The perimeter would be 20’

All the sides add up to equal 20 feet (4+4+6+6)

Answer: Option C

$AC = 2\pi$

Step-by-step explanation:

The arc length is calculated as

$L = \theta * R$

Then

$AC = \theta * R$

We know that

$BC = 24\ ft$

If BC is the diameter of the circumference then the radius R is:

$R = \frac{BC}{2}$

$R = \frac{24}{2}$

$R = 12\ ft$

Now we convert the anglo from degrees to radians $\theta= 30\° * \frac{\pi}{180\°}\\\\\theta=\frac{1}{6}\pi$

Finally

$AC = \frac{1}{6}\pi * 12$

$AC = 2\pi$

Write the equation of the circle with center (3, 2) and (−6, −4) a point on the circle.

yulyashka [42]

The equation for a circle is as followed:

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

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

We are given (h,k) and need to find the radius. To do so, we can use the distance formula to find the distance from the center to the point on the circle:

$d= \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

Plug in the two points:

$d= \sqrt{(3-(-6))^2+(2-(-4))^2}$

$d= \sqrt{(9)^2+(6)^2}$

$d= \sqrt{117}$

If the distance from the center to the edge of the circle is the square root of 117, then r^2 = 117.

The answer is:

$(x-3)^2+(y-2)^2=117$

Find the solutions of the inequality. Show your work. 4b – 3 > –1

Gwar [14]

So we have to find b we are going to try to isosiate b
4b - 3 > -1 now we are going to isosiate the b so add 3 from both side and get 4b > 2
