1. kian is driving 48 miles per hour and is starting to merge onto the highway; therefore, he must
increase his speed. he gradually accelerates at a rate of 7 miles per hour for several seconds.
a. substitute the initial velocity and constant acceleration into the formula to write an equation to
represent the distance kian travels.
b. use the quadratic formula to determine the roots of the equation. what do the roots represent in
the context of the problem situation? explain your reasoning.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
