A surveyor has to determine the distance between points A and B that lie on opposite
banks of a river. Another point C is 450 m
from A, on the same side of the river, such
that BÂC = 45° and ACB = 55°. Find the
distance from A to B to the nearest meter

step-by-step explanation:

yes. we do proportions in probabilities.

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.
