Answer:
Table 3
Step-by-step explanation:
In a proportional relationship there must be a constant rate of change.
The first table:
6-5 / 9-7 = 1/2
5-3 / 7-4 = 2/3
These are not equal so it is not proportional.
The second table:
10-8 / 150-120 =2/30
8-5 / 120-75 = 3/45
These are not equal so it is not proportional
The third table:
10-8 / 12-10 =2/2 = 1
8-6 / 10-8 =2/2 = 1
These are equal so this table is proportional.

The distance in scientific notation is 5.6x10^5 miles. ^ is to the power of. Start from the right of a number and count the number of spaces till you get between the first two numbers, and that is how you get your exponent. It would be a different case if you had a decimal number though. For example the scientific notation of 0.00000256 would be 2.5x10^-6. You would count the number of spaces from the left to right and the exponent would be a negative.
