Simplify the square root of:
√32

4

Step-by-step explanation:

factor the square root of 32

to get a total of 32, you do 4 times 4, which is 16

16 times 2 =32

16 is a perfect square so it's outside of the square root symbol, but you can't find the square root of 2 without it being irrational.

So,

final 4

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
