Answer:

0.73 yrs

Step-by-step explanation:

if t is time in years

quarterly

600 = 200(1 + 0.06625/4)^4t

3 = (1 + 0.06625/4)^4t

ln3 = 4tln(1. + 06625/4)

t = ln3 / (4ln1.0165625)

t = 16.7198 yrs

continuously

600 = 200e^(0.06875t)

3 = e^(0.06875t)

ln3 = 0.06875t

t = ln3 / 0.06875

t = 15.9798 years

Δt = 16.7198 - 15.9798 = 0.73 yrs

Answer:

see below

Step-by-step explanation:

All of the given data sets have x-values that are sequential with a difference of 1. That makes it easy to determine the sort of sequence the y-values make.

first choice: the y-values have a common difference of -2. This will be matched by a linear model.

second choice: the y-values have a common difference of +2. Again, this will be matched by a linear model.

third choice: the y-values have a common ratio of -2. This will be matched by an exponential model.

fourth choice: the y-value differences are 3, 5, 7, increasing by a constant amount (2). This is characteristic of a sequence that has a quadratic model.
