Approximate the value of each expression shown. Explain your reasoning.
a.√ 38
b. √ 79

a.√ 38  =

b. √ 79 =

Step-by-step explanation:

Here we have , to find Approximate value of each expression shown.

We know that , A square root of a number is a value that, when multiplied by itself, gives the number.  Example: 4 × 4 = 16, so a square root of 16 is 4.  Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root.  Example: √36 = 6 (because 6 x 6 = 36)

a.√ 38

We know that value of √36 = 6 , and here we have √ 38 which value will be slightly greater then 6 Let's find out:

⇒

⇒

b. √ 79

We know that value of √81 = 9 , and here we have √ 79 which value will be slightly less then 9 Let's find out:

⇒

⇒

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
