Determine the equation of the circle graphed below.
Diano4ka-milaya [45]

Answer:

(x - 6)^2 + (y - 2)^2 = 4

Step-by-step explanation:

Required

The equation of the circle

The equation of a circle is:

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

Where:

Center = (h,k)

radius \to r

From the graph, we have

(h,k) = (6,2)

r = 2

So:

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

(x - 6)^2 + (y - 2)^2 = 2^2

(x - 6)^2 + (y - 2)^2 = 4

Jelanis family is putting a fence around their yard. They need 106 feet of fencing. The length of the yard is 5x+8. Find the len
aleksley [76]

Answer:

The length of the yard is 48\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of the yard required to be fenced is equal to

P=(5x+8)+2(3x-1)+2(x-2)\\P=13x+2

P=106\ ft

so

106=13x+2

solve for x

13x=106-2

13x=104

x=104/13=8\ ft

Find the length of the yard

5x+8=5(8)+8=48\ ft
