Question

The number of books in a small library increases according to the function B =

7800e0.03t, wheretis measured in years. How many books will the library have after 7
years?​

Answer 1

9625books

Explanation:

If the number of books in the library increases according to the function

B = 7800e0.03t, the number of books that will be there after 7years can be gotten by simply substituting the value of t =7 into the modeled function as shown:

B =7800e0.03t,

B = 7800e^0.03(7)

B = 7800e^0.21

B = 7800×1.234

B = 9625.2

This shows that there will be approximately 9625books in the library after 7years
