Determine the
constant of
proportionality.

Step-by-step explanation:

Time is 2 miles 110 is 55 miles per hr

5 hrs *55 mph= 275

12*55= 660

Yes it is in proportion.

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.
