Determine the equation of the circle graphed below

Irina-Kira [14]

Answer:

$(x-1)^2+(y-6)^2=16$

Step-by-step explanation:

The equation of a circle is given by $(x-h)^2+(y-k)^2=r^2$ , where $(h,k)$ is the center of the circle and $r$ is the radius of the circle.

From the diagram, we can find the following:

the radius of the circle is 4
the center of the circle is located at (1,6)

Thus, we have:

$(x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}$

Simplify the following expression. 3^11/5 divided by 3^-9/5

san4es73 [151]

Answer:

Answer is 81.

Step-by-step explanation:

Given two expressions are $3^{\frac{11}{5} }$ and $3^{-\frac{9}{5} }$

Now we divide first expression by the second.

$\frac{3^{\frac{11}{5} }}{3^{-\frac{9}{5} } }$

$3^{\frac{11}{5} }.3^{\frac{9}{5} }$

$3^{\frac{11}{5}+\frac{9}{5}} = 3^{\frac{20}{5} }=3^{4}=81$

Therefore 81 is the answer.
