what is this?
what does this mean
The problem begins by saying that 100 gallons of the mixture contains 3 percent of citrus extract
But we can see that if we put x=0 in the equation, then we find the equation tells us that the percentage of sodium extract is 3%
Sorry, not sodium, its citrus
Is that clear?
is citrus, where you got sodium?
So isn't that a contradiction
I told you not sodium, I miswrote it its citrus
I am currently working with sodium, and so that is an obvious slip of finger
i have a question i don't quite understand, i am preparing for a exam. A 100-gallon mixture of citrus extract and water is 3% citrus extract, and it needs to be diluted. The function f(x)=3/100+x represents the percentrage (in decimal form) of the miture that is citrus extract when x gallons of water are added. Find the domain of f(x). Then, find the percentage of citrus extract in the mixture after 50 gallons of water are added to it.
but where you got sodium from?
I miswrote it, it should be citrus not sodium
man, can you just go straigh to the problem plz plz, i need to know this before my test ,i already going to be late for 5 minutes
if you won't help me, just tell me,
Now according to the equation, when x=0 the percentage of citrus is 3
That means the starting point of the equation is 77% water and 3% citrus
So you can take out 77/100 times 100 gallons of water from it
As that is already there at the starting point
you must make a function?
So your domain is -77 to any higher number
I told you if you don't understand my arguments it will be difficult to understand the solutions
just keep going
You didn't even realize that I did a mistake
Pi wouldn't it be 97 rather than 77 percent water?
were would the trest 20 go..
ok, go straigh to the problem, geez, i am super late.
The lower boundary of x is -0.03 and the higher boundary is infinity
i just need this problem, the rest i understand
This is the answer to the first part of the question
Now for the second part, just put 50 into x and you will get the solution
what is the domain? the wsa the first part of the solution
Yes, the domain is-0.03 to infinity
what would the percentage of citrust extract in the mixture after gallons of water are added to it, 3/150, 1/50?
is the right?
Oh dear ther is a great mistake
what you mean?
By the expression 3/(x+100) you meant 3/100+x
Which are completely two different things
I worked on it according to the expression 3/100+x
3/100+x means \[3/100 + x\]
the is how it was in the book, you working on it right
Then you said it wrong when you said 3/150
It should be (3/100) + 50
then how you find the percentage of citrux extract in the mixture after 50 gallons of water are added/
where woluld the x go?
It should be (3/100) + 50
the is the answer?
If you are saying everyting correctly
But I have great doubts, that there is some error in what you typed
Just tell me one thing, is the expression 3 over 100+x or is it 3 over 100 plus x
i went , everything is correct. 3 over 100+x
Then all this time I have been doing it wrong
As by the expression 3/100+x its actually doesn't mean x over (100+x)
Iam sorry for the typos
Do you have any more time?
ok, go straigh to the answer., in two minutes i have to leave, for sure
