Solve for n.
21n=15
Please help

n =

Step-by-step explanation:

Given

21n = 15 ( divide both sides by 21 )

n = ← divide ( cancel) 15 and 21 by 3, thus

n =

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.

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
