What is the area of a regular hexagon that has a radius of 20 inches.

Over which interval is the graph of f(x) = x2 + 5x + 6 increasing?

Rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
