How long will it take for the money to triple? compounded continuously.

If e^(rt) is 3, then taking logarithms tells you

... rt = ln(3)

So, the time to triple the amount is

... t = ln(3)/0.0275 ≈ 39.95 . . . . years

The working out that is shown in the picture appears to be correct.

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
