A ship is stationary at sea. A tugboat is 21 km away at a bearing of 080°, and a yacht is 18 km from the tugboat at a bearing of 120°.
Draw a scale diagram showing the positions of the three vessels.
Use a scale of 1 cm : 3 km.
Use your diagram to find the distance of the yacht from the ship to the nearest km.

answer: the common difference is -0.10

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.
