If the distance covered by an object in time t is given by s(t) = 5t^2+ t + 2, where s(t) is in meters and t is in seconds, what is the distance covered in the interval between 1 second and 4 seconds?

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
