Answer:

diameter = 8 miles

Step-by-step explanation:

Area of a circle = πr²

πr² = 50.24

3.14*r² = 50.24

r²= $\frac{50.24}{3.14}\\\\$

r² = 16

r² = 4²

r=√4²

r = 4 miles

diameter = 2 *radius = 2*4 = 8 miles

Describe the transformation done to y = 1/x to get y = 1/4x -12?

BabaBlast [244]

The transformation is done to y=1/x to get y=1/4x-12. We defined a turning point in the equation which will indicate the point in the graph.

We changed the form from y=x to y=x+c. In this case, we use 1/2 for the and constant C value which is -12.

Find center and radius<br> (x-3)^2+y^2=8

Flauer [41]

Answer:

<h2>Center: (3, 0)</h2><h2>Radius: 2√2</h2>

Step-by-step explanation:

The equation of a circle in standard form:

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

(h, k) - center

r - radius

We have the equation:

$(x-3)^2+y^2=8\to(x-3)^2+(y-0)^2=(\sqrt8)^2$

Therefore

the center: $(3,\ 0)$

the radius: $r=\sqrt8\to r=\sqrt{4\cdot2}\to r=\sqrt4\cdot\sqrt2\to r=2\sqrt2$

Rewrite the equation below so that it does not have fractions.

lidiya [134]

Answer:

$\frac{15}{20} x-2=\frac{8}{20}$

Step-by-step explanation:

$\frac{3}{4} x-2=\frac{2}{5}$

3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that

$\frac{3}{4} =\frac{15}{20}$

$\frac{2}{5} =\frac{8}{20}$

$\frac{15}{20} x-2=\frac{8}{20}$

You can then multiply both sides by twenty to solve this equation.

Hope this helps.
