Identify the center and the radius of a circle with equation (x-4)^2+(y+2)^2=9

center:(4,-2)

Radius: 3 units

Step-by-step explanation:

The standard equation of a circle is given as , where (h,k) is the center and r is the radius of the circle.

The given equation is .

We compare to the standard equation of the circle to get;

and

Hence the center of the circle is (4,-2).

Also, we have

Therefore

units.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
