I'll do the first one to get you started
So we have g(f(x)) which means that we start with g(x) and replace the 'x' with 'f(x)' to get g(f(x))
g(x) = ( x - 4 )/2
g(f(x)) = ( f(x) - 4)/2 .... replace every x with f(x)
g(f(x)) = (2x+4-4)/2 .... replace f(x) on the right side with 2x+4
g(f(x)) = (2x+0)/2
g(f(x)) = (2x)/2
g(f(x)) = 1x/1
g(f(x)) = 1x
g(f(x)) = x
Let me know if you need help with the other one.
Answer:
V = (1/3)(π)(6 in)²(10 in) = 120π in³
Step-by-step explanation:
The volume of a cone of radius r and height h is V = (1/3)πr²h.
Here, that volume is V = (1/3)(π)(6 in)²(10 in) = 120π in³
Answer:
14/17
Step-by-step explanation:
Find the value to make the equation true
1) ?/1 = 14/17
x : 1 = 14 : 17
x = 1 * 14 : 17
x = 14 : 17
x = 14/17
Everyone got a calculator.....each weighed 16 oz.......gave them to 20 students.....20 * 16 = 320 total oz
16 oz = 1 lb
320/16 = 20 lbs <==
or, if u just think about it...u gave 16 oz to each student.....16 oz = 1 lb...so u gave 1 lb to each student....20 students = 20 lbs
Answer:
This problem is acually really simple.
Step-by-step explanation:
all you have to do is replace the a with a 3. SO It would look like this:
g(x)=3f(x)
hope this helps :)
