Answer: what’s you’re question
Step-by-step explanation:
(2.5 x 10^-8)(9 x 10^-10) = (2.5 x 9) x (10^(-8 + (-10))) = 22.5 x
10^(-8 - 10) = 2.25 x 10^1 x 10^-18 = 2.25 x 10^(1 + (-18)) = 2.25 x
10^(1 - 18) = 2.25 x 10^-17
Step-by-step explanation: So when graphing this problem, we start at -3 on our number line with an open dot because <em>k</em> is less than but not equal to -3. I have shown this in the image attached below.
We then draw an arrow going to the left to represent all number less than -3.
Finally, we put our answer in set notation which is shown below.
{K: k < -3}
All this means is that if we take any number less than -3, this will be a solution for the inequality <em>k < -3</em>.
6 x 94
= 6(90 + 4)
= 6 x 90 + 6 x 4
= 564
