Ten data points are in the scatterplot shown, along with a line of best fit. Which of the following best estimates
the predicted value of y, when x = 6.5?

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3

How many zeros does this polynomial function, y=(x-8)(x+3)^2

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).
