Simplify completely 25 w to the sixth power over 10 w to the third power divided by 30 w squared over 5 w.

malfutka [58]

$\cfrac{25w^6}{10w^3}: \cfrac{30w^2}{5w}= \cfrac{5w^3}{2}* \cfrac{5w}{30w^2}= \cfrac{w}{2}* \cfrac{5w}{6}= \cfrac{5w^2}{12}$

victus00 [196]

The answer is 8/17 because you have to change the fractions to improper fractions then change the division sign to a multiplication sign. Then change the second fraction by flipping the two numbers then multiply and reduce.

Graph each circle given below right the center and the radius of each circle

Paraphin [41]

Answer:

Center: (-1,8)

Radius: 1

The graph is attached.

Step-by-step explanation:

The equation of the circle has the form:

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

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

The equation given in the problem is

$(x +1)^{2}+(y-8)^{2}=1$

Therefore:

h=-1

k=8

Then, the center is (-1,8) and radius is 1.

You can graph the circle with its center at the (-1,8) and a radius of 1 as you can see in the figure attached.
