The equation for a circle with center (h, k) is (x - h)2 + (y - k)2 = r2. if a circle is modeled by the equation (x - 4)2 + (y + 6)2 = 49, what is the center of the circle? a) (4, 6) b) (4, −6) c) (−4, 6) d) (−4, −6)

Given that abcd is a rhombus, what is the value of x?

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
