When a number is written in scientific notion, how can you tell right away whether or not it is or than or equal to one?

Well, to know right away whether or not a number is equal to 1, you need to know what 1 is in scientific notation. 1 * 10^0. Easy enough :) To know if the number is greater than one, any positive number multiplied by 10^a number higher than 0 is greater than one. As well as any number greater than one multiplied by 10^0 or a positive number. For numbers less than one, the way to know is if the number is being multiplied by 10 ^ a negative number. I hope this helps :)

Slope formy2-y1/x2-x1(-2,-3) and (3,7))/ ) = 10/5the slope is 2the answer is bhope this !

Wow. that is a really cool question.
