!an astronaut must perform a repair at 30m outside her spaceship. it moves at a speed of 2m/minute. she took 20 minutes to complete the repair then she returned to the ship. during its release it uses an average of 760 ml of oxygen per minute. what is the amount of oxygen used by the astronaut during its exit? show your calculations

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.
