select the irrational number? A)√9 B)√12 C)√16 D)√20 E)√25 (there should be more than one answer)
GenaCL600 [577]
The answers are:
__________________________
    [B]:  "√12 " ;   AND:
__________________________
    [D]:  "<span>√20" .
__________________________
Note:  "Irrational numbers" have decimals that are:  1) non-terminating;  AND:  2) non-repeating.
__________________________
Consider the answer choices given; and consider the given information that there "should be no more than one answer.
__________________________________
Consider the following answer choices:
__________________________________
Choice A)  "</span><span>√9"  =  3 .  Rule out this choice.
__________________________________
Choice C)  "</span><span>√16" = 4 .  Rule out this choice.
__________________________________
Choice E)  "</span><span>√25" = 5.   Rule out this choice.
_________________________________
We are left with 2 (two) remaining answer choices:
    [B]:  "</span>√12"  ;  and:  [D]:  "<span>√20" .
_________________________________
If there are more than one answer, then these two choices should be the correct answer.   However, let us explore these two choices, using a calculator.
____________________________
    [B]:  </span>"√12"  =  3.4641016151377546

    [D]:  "√20"  =  4.4721359549995794
_________________________________
These two answer choices should the correct answers.

WILL GIVE BRAINLIST the answer is not 74​
olga nikolaevna [1]

Answer:

82

Step-by-step explanation:

180+148+xy=360

xy=32

arc=32=double the angle=16 degrees

Since both are radii they are equal. It is an isoceles triangle so angle x equals angle y.

180=16=164/2=82

I HAVE A MATH TEST PLZ HELP I'M GIVING OUT 50 POINTS PLZ<br><br> S.O.S I HAVE MATH
Nady [450]

Answer:

<em>Graph included as picture</em>

Step-by-step explanation:

To solve this, plot the given points on the graph

Draw a line through them.

Now select two of those values and we'll find the rate of change.

We'll be using (1,-1) and (3,3)

To find rate of change we will be using the formula: \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

y_{2} = 3\\y_{1} =-1\\x_{2} = 3\\x_{1} = 1

\frac{3-(-1)}{3-1} = \frac{4}{2} = 2

So the rate of change is 2

You will use this rate of change for your other function because they both have the same rate of change

Since we have the rate of change, we can create the slope intercept form formula: y = mx +b

Just substitute for the variables we know

m = rate of change/slope = 2

b = y-intercept = -3

y = 2x + -3

<em>[If you connected all the points in your graph, that's how you found the y-intercept]</em>

Now we have to create the formula for the second function.

We know it will have that same slope of 2

so we have y = 2x + b

To solve for b we can plug in the values we do have which would be (x,y) of (3,6)

6 = 2(3) + b

Now solve

6 = 6 + b

6 (-6) = 6 (-6) + b

0 = b

b = 0

This mean that the y-intercept will be on (0,0)

Plot that point

Now we finish the formula

y = 2x + 0

Connect the dots, make sure the line continues on both of them past the dots and now you have your graph!

I've included a picture of the graph for your reference. I hope this helps, don't be afraid to reach out with further questions!
