Answer:
x*(x+2)= 63 7 and 9
Step-by-step explanation:
The domain would be -2, the x-intercept.
Answer:
x=5
Step-by-step explanation:
I was working on this problem also.
Maybe my version will help, too.
You need to sketch f given the information you have.
f'(x) is approximately a a cubic polynomial which means f will look like a quartic (think W)
f slopes down (negative slope) to x=2 and then slopes down again...this is a horizontal tangent.
f then slopes down to to x=5 where is has a minimum and then slopes up.
if im not wrong
Answer:
Number of carbon atoms present in the sample are 391.
Step-by-step explanation:
We are given that,
Ratio of carbon to hydrogen atoms = 1 : 4
It is given that a sample of methane consists of 1564 hydrogen atoms.
Let the carbon atoms in the sample = x
So, we have the relation,
i.e. 
i.e. 
i.e. x= 391
Hence, the number of carbon atoms present in the sample are 391.
Here You Go.
5.8, 5 2/5, 4.33, 4.25
By converting them to decimals, you can sort them out even more easily. This is the strategy to use.
