The answer is A so pick that
2.32*103 = 2.39E3, or 2.39*10^3
This result is likely wrong because I first thought your 103 literally meant 103. Now it seems that you meant 10^3 (10 to the third power). So, ignore the above result and multiply again: 2.32*10^3. This is already in scientific notation.
4.2*10^4 is already in scientific notation.
4.2*10^(-2) is already in scientific notation.
5700=1.7*10^3 (answer in scientific notation)
6548000= 6.55*10^(-6) (in scientific notation)
Cause it’s -$75 he would have to put $75 to achieve a balance of $0
I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!
- Midpoint formula is
.

So starting with this one, we will be solving for the coordinates of the unknown endpoint separately. Starting with the x-coordinate, since we know that the midpoint x-coordinate is 5 and the x-coordinate of N is 2, our equation is set up as such:
From here we can solve for the x-coordinate of Q.
Firstly, multiply both sides by 2: 
Next, subtract both sides by 2 and your x-coordinate is 
With finding the y-coordinate, it's a similar process as with the x-coordinate except that we are using the y-coordinates of the midpoint and endpoint N.

<u>Putting it together, the missing endpoint is (8,4).</u>
<em>(The process is pretty much the same with the other problems, so I'll go through them real quickly.)</em>

<u>The missing endpoint is (7,2).</u>

<u>The missing endpoint is (-5,1).</u>
