Write the equation of the circle centered at (4, - 9) with diameter 16. HELP A GIRL OUT

Mathematics
1 answer:
iragen [17]3 years ago

Answer:

16= (x-4)^2 +(y+9)^2

Step-by-step explanation:

hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2

r= the radius (in your case you have the diameter so you do not need to square it)

(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)

a nice rating would help out

3 ( x + 1) = 2 ( x + 11)    Use the Distributive Property
   3x + 3 = 2x + 22      Subtract 2x from both sides
     x + 3 = 22              Subtract 3 from both sides
           x = 19

Ian buys a rectangular water cooler that has a volume of 4 1/16 cubic feet. The water cooler is 1 1/4 feet long and 1 feet wide.
mestny [16]
To find the height of the water cooler, you will use the formula for finding the volume of a rectangular prism and solve for the missing height.

V = lwh
4 1/16 = 1 1/4 x 1 x h; simplify the right
<u>4 1/16</u> = <u>1 1/4 h</u>; divide both sides by 1 1/4
1 1/4      1 1/4
h = 3 1/4 feet

The height of the water cooler is 3 1/4 feet.
