Given graph of f(x)=k/x and g(x)=x.T(3.16;3.16) is the point of intersection of f and g. Write down the domain of f

Answers

Answer 1

Answer: Hello,

As said T is the point of intersection of f and g, this means that there are only one point and that k=+1.

So dom f= $R ^(+)_0$ (x>0)

A color printer will print 8 pages per minute how many minutes will it take to print a report that has 136 pages

Answers

The given color printer prints 136 pages in 17 minutes with a rate of 8 pages per minute.

Given that,
A color printer will print 8 pages per minute how many minutes will it take to print a report that has 136 pages is to be determined.

What is the rate of change?

Rate of change is defined as the change in value with rest to the time is called rate of change.

Here,
rate of printing = 8 pages / minute
Now, for the printing of 136 pages,
Time = 136 / 8 = 17 minutes

Thus, the given color printer prints 136 pages in 17 minutes with a rate of 8 pages per minute.

You would have to divide 8 divided by 136... Here is the picture.

From a class of girls and boys the probability that one student chosen at random to answer a question will be a girl is 1/3 . If four boys leave the class , the probability that a student chosen at random to answer a question will be a girl is 2/5 . How many boys and girls are there in the class before the four boys leave ?

Answers

let the no. of girls be x and boys be y......
x/y=1/3
=>3x=y ...............(I)
now 4 boys leave the class is then
x/y-4=2/5
=>5x=2y-8
(I)=>5x=2(3x)-8
x=8
now 3x=y
=>y=24
therefore no. of girls is 8 and the no. of boy is 24..............

I need to find how many solutions does the system have.

Answers

From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)
