Answer:
(2,20)
Step-by-step explanation:
The given function is
To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;
For the first point we substitute x=3 and f(x)=250
This is true.
For the second point (2,20), we put x=2 and y=20 to get:
This is false, hence (2,20) does not lie on this curve.
For (1,10), we have:
This is also true
Finally for (2,50), we have;
This is also true.
Answer:
As the model is shown below.
As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.
The value of fifth part of each of them is 1/5.
If we consider each part of a thing as one,
So, total number of parts = 15
Total thing=3
So, the answer of the above model is 3÷ 15.
Out of all the options which are 15÷15 , 3÷115 , 3÷15, 15÷15 →3÷15 is correct.
