X Katelyn incorrectly simplified an expression using the steps shown below.
(3 x 10^) (9 x 10) + 0.0002
(27 x 10-2) + 0.0002
= (27 x 10-2) + (2 x 10-4)
= (0.27 x 10 4) + (2 x 10-4)
= 2.27 x 10-8
Which of the following equations from Katelyn's steps are false?
Select all that apply.
Х
(3 x 104) (9 x 10²) + 0.0002 = (27 x 10-2) + 0.0002
(27 x 10-2) + 0.0002 = (27 x 10-2) + (2 x 10-4)
(27 x 10-2) + (2 x 10-4) = (0.27 x 10-4) + (2 x 10-4)
(0.27 x 10-4) + (2 x 10-) = 2.27 x 10-8

What values of c and d make the equation true?

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
