2. Jaclyn estimates the square root of 50 in the following way:
/50 = 2/ 25 = 2 □5=10
(A) Explain why her reasoning is incorrect.
(B) Estimate the square root of 50 to the nearest tenth without using your calculators. Show your work.

(B) 7.1 is the estimated square  root of 50

Step-by-step explanation:

A. √50 =  √2 √25

= 5√2.

Jaclyn did not take the square root of 2.

B. We estimate the square root of 2.

Trial and improvement:

It must lie between 1 and 2 so we try 1.5:

1.5 * 1.5 = 2.25

Its  < 1.5 so try 1.4

1.4 * 1.4 = 1.96.

So it is a little above 1.4.

Try 1.45:

1.45 * 1.45                        

     1.45

  *  1.45

            725

          5800

         14500

       2.1025

= 2.1025.

- this is above 2 so the answer is between 1.40 and 1.45 but closer to 1.4.

A good estimate is 1.42

So the square root of 50 is about 5*1.42 = 7.1

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.

i believe the answer is 323 ft
