Answer:

240

Step-by-step explanation:

Given that each book on a certain shelf is labeled by a single category. For every 2 history books, there are 7 fantasy books and for every 3 fantasy books, there are 5 reference books

Let history, fantasy and reference books be x,y,z

Then x:y =2:7, y:z = 3:5

Or x:y:z =6:21:35

Now when we double x:y we get

x:y = 4:7 while y:z=3:5

we get

x:y:z = 12:21:35

Original fantasy books = $\frac{21}{62}$

New fantasy books = $\frac{21}{68}$

Difference = 0.3387-0.3088

=0.299

Approxly 3 is differene equivalent to 60

So new X = $60*12/3\\=240$

In this composite function, (f◦g)(x) where f(x)=(X-3) and g(x)=X^2 what is (f◦g)(x) when x=1?

Alekssandra [29.7K]

Answer:

When x = 1, (f◦g)(x) is -2.

Step-by-step explanation:

Composite function:

The composite function of f and g is given by:

$(f \circ g)(x) = f(g(x))$

In this question:

$f(x) = x - 3, g(x) = x^2$

Composite function:

The composite function is:

$f(g(x)) = f(x^2) = x^2 - 3$

At x = 1

$(f \circ g)(1) = 1^2 - 3 = 1 - 3 = -2$

When x = 1, (f◦g)(x) is -2.
