There are 70 historical fiction books in the school library. Historical fiction books make up 1/10 of the library's collection.

Gre4nikov [31]

Answer:

There are 700 books in Library Collections.

Step-by-step explanation:

Given:

Number of historical books = 70

The equation used to find the totals number of books in library collection.

$\frac{1}{10}b = 70$

where b⇒ Total number of books in library collections.

We need to find the Total number of books in library collections.

Solution:

$\frac{1}{10}b = 70$

Now by solving the above equation we get;

First we will multiply both side by 10 we get;

$\frac{1}{10}b \times 10= 70\times 10\\\\b =700$

Hence there are 700 books in Library Collections.

Using an exponential function, it is found that f(5.5) = 19.8.

<h3>What is an exponential function?</h3>

An exponential function is a function in which the growth rate is a percentage, modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the rate of change.

f(3.5) = 25 means that:

$ab^{3.5} = 25$

$a = \frac{25}{b^{3.5}}$

f(8.5) = 14 means that:

$ab^{8.5} = 14$

Hence:

$\frac{25}{b^{3.5}} \times b^{8.5} = 14$

$25b^5 = 14$

$b = \sqrt[5]{\frac{14}{25}}$

$b = 0.89$

$a = \frac{25}{0.89^{3.5}} = 37.59$

Hence, the function is given by:

$y = 37.59(0.89)^x$

Then, when x = 5.5:

$f(5.5) = 37.59(0.89)^{5.5} = 19.8$
