Which is the equation of a parabola with a directrix at y = 2 and a focus at (5, 0). Y = one fourth(x − 5)2 1 y = one fourth(x 1)2 − 5 y = −one fourth(x 1)2 − 5 y = −one fourth(x − 5)2 1.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

stops on an even number.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
