Which of these numbers is irrational?

An irrational number is not ending and non repeating

Square root of 16=4

Square root of 100=10

Square root of 36=6

These are all rational

The square root of 15=3.872983

The answer is square root of 15

B.

Step-by-step explanation:

We have been given four numbers. We are asked to find the irrational number from our given number.

A.

Since we can write 4 as a fraction, therefore, is a rational number.

B.

Since our given number has non-terminating non repeating decimal, therefore, is an irrational number.

C.

Since we can write 6 as a fraction, therefore, is a rational number.

D.

Since we can write 10 as a fraction, therefore, is a rational number.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
