One leg of a right triangle measures 10 inches while the other leg measure square root of 21 inches. What is the length of its hypotenuse?

11 inches

Step-by-step explanation:

hypotenuse² = leg₁² + leg₂²

                     =10² + (√21)²

                    = 100 + 21

                    = 121

Hypotenuse = √ 121 = √11*11 = 11 inches

10^2+√21^2= 100+21= 121

square root of 121= 11

Answer is 11 inches

Step-by-step explanation:

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.
