You're in luck i'm feeling the mood to do your homework :)

2) The table would change, the number of hydrogen and oxygen atoms would be the same ALWAYS.
3) 15 Hydrogen Atoms and 5 Nitrogen Atoms (5*3=15, 5*1=5)
4) Not so great with System of Equations, I feel like there is a value missing. It'd be much easier if I was given how many people went.

P = Rs 800
Rate = 8%
Time = 2 yrs .

To Find :-

Compound Interest .

Solution :-

We know CI as ,

> CI = P ( 1 + R/100)ⁿ

> CI = Rs 800 ( 1 + 10/100)²

> CI = Rs 800 × 11/10 × 11/10

> CI = Rs 968 .

F(x)=sqrt x+2; g(x)=sqrt 8x-6. FInd f(g(x))

zhenek [66]

Hello!

This question is an example of composition of functions. It is using range values of some given function as domain values of some other given function to find new range values. Remember that the domain of the composite function will be the same as the domain of the first function.

Given f(g(x)), for f = $\sqrt{x+2}$ , substitute x with g(x) = $\sqrt{8x-6}$ .

Therefore, $f(g(x))= \sqrt{\sqrt{8x-6} +2}$ .

Given f(x) = 3x + 2 and g(x) = 2x - 1, find (g(x))2.

valina [46]

Answer:

C (if the sign after the digit 1,2,3,4 is not minus !!!)

Step-by-step explanation:

$f(x)=3x+2\\\\g(x)=2x-1\\\\\\g^2(x)=(gog)(x)=g(g(x)=g(2x-1)=2(2x-1)-1=4x-2-1=4x-3\\\\\\if \ you\ means \ g(x)*g(x)\ then\\\\(g(x))^2=(2x-1)^2=4x^2-4x+1:\ answer \ C$
