7 0

Answer:

Total = 800 books

Step-by-step explanation:

It is given that,

In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.

There if the library has 240 non-fiction books.

Let non fiction books are 3x and fiction books are 7x.

ATQ,

3x=240

x=80

Fiction books = 7x = 7(80) = 560

Total no of books = fiction books + non-fiction books

= 240 + 560

=800

Hence, the total no of books are 800.

Solve the equation below using a graphing
UNO [17]

Answer:

<em>x = 0.05</em>

<em>x = 1.57</em>

Step-by-step explanation:

The given equation is:

e^x-\ln 2x = 3.7

Moving all terms to the left side:

e^x-\ln 2x - 3.7=0

Now we define a function:

y=f(x)=e^x-\ln 2x - 3.7

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57
