The difference of course is the symbol between the f and g letters.
The circle 
notation means we're doing a function composition.
Writing 
is the same as saying 
where g is the inner function.
Here's an example
f(x) = x^2
g(x) = 3x
f( g(x) ) = ( g(x) )^2 ... note how x is replaced with g(x)
f( g(x) ) = ( 3x )^2
f( g(x) ) = 9x^2
-------------------
On the other hand, the dot notation means we multiply the f(x) and g(x) functions.
Going back to the previous example, we could say
$2 is the cost of one hat because if you multiply 8 by 4 you get 32. Then subtract 32 from 46 and you get 14 which you divide by 7 and get 2.
If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.
Your math should look like this: 538/8= about 67 pounds.
Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*
So, your answer should be *67* pounds.
*Use paper and a pencil! Sometimes doing mental math can be challenging with a problem like this. So use paper and a pencil, checking your answer wont hurt either!*
Answer:
50%
Step-by-step explanation:
72000-48000=24000
24000 is 50% of 48000
48000+24000=72000
It's 50%, im sorry if it's confusing
Answer:
37
Step-by-step explanation:
-3x^{2} + 1
replace (x) with (-2)
-3(-2)^{2} + 1
6^2 +1=36+1
=37
