The lengths of the sides of a triangle are in the ratios 2:6:7 The length of the longest side of the triangle is 24.5 cm.
Work out the perimeter of the triangle.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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.
