The equation of a circle with a center of (h,k) with a radius of "r" is
(x-h)^2 +(y-k)^2=r^2

looking at the given equation,
5x^2 +5y^2=20
divide 5 to both sides to get
x^2+y^2 =4

now compare that to the equatio of a circle shown above

31

Step-by-step explanation: you have to change day into 24 and hour into 1 since there are 24 hours in a day so once you do that if you divide the left equation by 24 to match the denominators then you have to divide the numerator(744) by 24 as well to get pounds on the right side which comes out to be 31

Hope this helps

What is the perimeter
Westkost [7]

Answer:

The answer to your question is:  letter D

Step-by-step explanation:

First we need to find the distances between the points,

distance AB = 8       get it just by counting the points in the graph

distance AC = 9       get it just by counting the points in the graph

To know the distance BC, use the pythagorean theorem

         c2 = a2 +b2

         c2 = 8² + 9²

         c² = 64 + 81

          c² = 145

         c = 12.04

Finally, perimeter = AB + AC + BC

                              = 8 + 9 + 12.04

                               = 29.04 units
