Answer:

Books remaining in  Andrews book collection = 29 books

Explanation:

 Andrews book collection contains 60 books.

 He donates 15% of his books to the national library,

        Number of books to library = 60 x 15/100 = 9

 Sells 1/4 of his books to a book dealer,

        Book sold to book dealer = 60 x 1/4 = 15

 Sells 7 books on amazon.

 Books remaining = 60 - (9 + 15 + 7)

                              = 60 - 31

                              = 29

Books remaining in  Andrews book collection = 29 books

Irina18 [472]

Answer:

Step-by-step explanation:

Exponential growth function can be represented as follows

y = e^{bt}

Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or

dy / dt =by , or rate of increase depends upon y itself

dy / y = bdt

integrating on both sides

lny = bt

y = e^{bt}

It represents very fast increase in y .

The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.

For exponential decay function

y = e^{-bt}

The decay of   a radioactive material is an example of exponential decay function.
