What perfect square is between 10 and 20?

16

Step-by-step explanation: 16 would be the only perfect square that is between 10 and 20. A perfect square means that a whole number multiplied by itself will give us 16. In this case, if we multiply 4 × 4 we get a product of 16 so 16 would be classified as a perfect square.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the correct answer is 1: 2
