Answer:

x≠-1,1

Step-by-step explanation:

f(g(x)) is a composition where g(x) is is substituted for x in f(x).

Recall, f(x) is 2/x. So we write 2/|x|-1. This places x in the denominator and 0 cannot be in the denominator x. Any value of x that makes the denominator 0 will not be in the domain.

|x|-1=0

|x|=1

x=1,-1

8. 36.8 = [11.5 – (2.5 X 3)]2
Anestetic [448]

Answer:

[11.5-(2.5*3)]^2=16

Step-by-step explanation:

We want to evaluate [11.5-(2.5*3)]^2

Let us evaluate within the parenthesis first:

[11.5-(2.5*3)]^2=[11.5-(7.5)]^2

\implies [11.5-(2.5*3)]^2=[11.5-7.5]^2

We again subtract within the bracket to obtain:

[11.5-(2.5*3)]^2=[4]^2

This finally gives us:

[11.5-(2.5*3)]^2=16

26.891 to the nearest ten thousands place
Ahat [919]

the number isn't large enough to round to the nearest ten thousandths.

 that would be the 4th digit to the right of the decimal point, so we would need the 4th and 5th numbers to the right in order to round the answer.

A 16-ounce package of frozen vegetables costs $2.10. How much would you expect a 12-ounce package to cost?
statuscvo [17]
Hi!

We need to find the cost per ounce. 
2.10/16 = 0.13125

It costs 0.13125 per ounce. 

Now find the cost of 12 ounces. 
12 * 0.13125 = $1.58

The answer is $1.58

Hope this helps! :)
