Justice hopes to build a fence around his garden he measures and determined that he needs 24 feet of fencing when he arrives at
Sunny_sXe [5.5K]

Answer:

It  will cost  $72 Justice to fence in his garden.

Step-by-step explanation:

Total length of the fencing around the garden =  24 feet

Cost of fencing per inch = $0.25

Now, as we know 1 foot  =  12 inches

⇒  24 feet =  24 x 12 inch  = 288 inches

⇒ 24 feet  =  288 inches

Hence, the total length of  fencing   =  288 inches.

Now, Total cost of Fencing

=Total length of fencing x Cost of fencing par inch

=  288 inches x ($0.25)

=  $ 72

or, the total cost of fencing = $72

Hence, it  will cost  $72 Justice to fence in his garden.

1 Point<br> The circle below is centered at (-3, 2) and has a radius of 3. What is its<br> equation?
arlik [135]

Answer:

(x + 3)^2 + (y - 2)^2 = 9

Step-by-step explanation:

<u>Equation for a circle:  (x – h)^2 + (y – k)^2 = r^2</u>

<u />

<u>Step 1:  Determine what h, k, and r are</u>

<em>h is the x value of the point:  -3</em>

<em>k is the y value of the point:  2</em>

<em>r is the radius of the circle:  3</em>

<u>Step 2:  Plug in and solve</u>

(x – h)^2 + (y – k)^2 = r^2

(x – (-3))^2 + (y – (2))^2 = (3)^2

<em>(x + 3)^2 + (y - 2)^2 = 9</em>

<em />

Answer:  (x + 3)^2 + (y - 2)^2 = 9
