The value of julie's savings account can be modeled by the function s(x) = 5,000(1.025)0.7x, where x is the number of years since 1980. what is the approximate growth rate of the savings account? 1.0.72%2.1.74%3.2.50%4.18.87%

#3

Step-by-step explanation:

from the formula given, the part "(1.025)" would be the growth factor or rate.

This part has a formula:

(1 + r)

where r is rate

So substituting, we get:

So, in pecentage, we have to multiply, thus we get:

0.025 * 100 = 2.5%

Answer choice #3

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
