Acircle is defined by the equation given below.
x2 + y2 –x- 2y - 11/4 = 0
what are the coordinates for the center of the circle and the length of the radius?
á (-1/2,-1), 4 units
b. (1/2,1), 4 units
c. (1/2,1), 2 units
d. (-1/2,-1), 2 units

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this

Common ratio, exponential function, half-life that's all i have so
