Find all the real fourth roots of 0.0001.

0.01

-0.1 and 0.1

0.1

-0.01 and 0.01

-0.1 and 0.1

Step-by-step explanation:

A fourth root is a number which multiplied by itself 4 times gives 0.0001.

Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.

0.1*0.1*0.1*0.1 = 0.0001

So the real fourth roots are -0.1 and 0.1.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
