# points help show work

Consider the points (4,-7) and (-6, 13). (a) Find the midpoint. Show work. (b) If the point you found in (a) is the center of a circle, and the other two points are points on the circle, find...

# How do you find the x intercepts and y intercepts of a circle with a given circle besides graphing?

The circle is not in the formula already. The equation is x^2+y^2+4x-6y+4=0 Also I am not sure whether I should complete the square or not.

# Optimization Problems

# Optimization Problems

A piece of plexiglass is in the shape of a semicircle with radius 2 m. Determine the dimensions of the rectangle with the greatest area that can be cut from the piece of plexiglass.

# How to you put x^2+y^2=x+2 into the standard form of a circle without graphing?

I know the standard form of a circle is (x-h)^2+(y-k)^2=r^2 but I don't see how to put x^2+y^2=x+2 into that form.

# if the radius is 18 inches then what is the diameter

# Cirlce P is tangent to each side of ABCD. AB= 20, BC=11, and DC= 14. Let AQ= x and find AD

helppppppppppppppppp :(

# AB and AC are tangents to circle O, and OC= 5X. find OC.

AB= 14+4X AC= 19-6x Making clear OC is just the radius its not the whole diameter. Help me please! I don't know what to do after I make equal the two tangents (I know they are congruent)...
