Find the vertex, focus and equation of the directrix for the conic given by (x + 1)^2 = -20(y - 3). sketch a graph of this conic

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 23 = 10x a. -1.93, 11.93 b. 1.93, -11.93 c. 1.93, 11.93 d. -1.93, -11.93

Interpret the following expression (5y^2-7)^3/(2y)^2

Ofin . (2,4) (2,1) a. y= 2 b. x= 2 c. x= -2 d. y= 2x
