Answer:

Option B is correct

Step-by-step explanation:

Given: h(x)=\frac{1}{x^2+1} is the result of the composition f(g(x)).

Also, g(x)=x^2+1

To find: f(x)

Solution:

Take f(x)=\frac{1}{x}

Now check whether h(x) is equal to f(g(x)) or not.

First find f(g(x))

f(g(x))=f(x^2+1)=\frac{1}{x^2+1}

Also, h(x)=\frac{1}{x^2+1}

Therefore,

h(x)=f(g(x))

So,

Option B is correct

One month, ruby worked 6 more hours than Issac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hour
garik1379 [7]
Ruby's hours will represent x+6
Svetlana's hours will represent 4(x+6)
Issac will represent x.

The equation would read:
x+(x+6)+(4(x+6))=126
x+x+6+4x+24=126
6x+30=126
Subtract 30 from both sides.
6x=96
Divide 6 on both sides to get x by itself.
x=16

So:
Issac worked 16 hours
Ruby worked 22 hours
Svetlana worked 88 hours.

To check your answer, plug in the values:
16+22+88=126
126=126

Hope this helps.

Anybody Can Figure This One Out ?
Karo-lina-s [1.5K]
So from 1150 to 230 lbs of flour remaining...
The percentage decrease was by 
percentage decrease = ((b-a)/b)*100
b is the original value
a is the other value
p= ((1150-230)/1150)*100
p = (920 /1150) * 100
p = (0.8) * 100
p = 80

The percentage decrease is 80% from 1150 to 230 lbs of flour.

Hope this helps :)
