Why is the product of a rational number and an irrational number Irrational?

Because the product is always non-termination,non-repeating decimal.

Step-by-step explanation:

If we have is irrational;   is rational such that , then is irrational.

A way to represent this is:

Note that we have a contradiction, because is not a rational number, as I stated in the beginning. Therefore, ab is irrational.

A

Step-by-step explanation:

Multiplying an irrational number by a rational number will always be an irrational number because irrational numbers do not repeat and terminate.

So for example multiplying pi by a rational like two you will have an irrational number because pi is an irrational number.

= 6.28318530718  as you could see that is an irrational number because there is no repetition or termination.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
