R2000 is deposited into savings account .Six months, later and every six months thereafter R2000 is deposited into the account is 16%p. a. compounded half yearly how many payments will it take to accumulate R 100000?​

sorry not sure

step-by-step explanation:

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.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
