Answer:
0, 17
3 1/2, 5
<u>-3 1/2, -12</u>
17
Step-by-step explanation:
First label the 2 points.
A = (3, 1/2, 5), B = (3, 1/2, -12)
Then calculate the vector from A to B:
And then calculate it's length by the formula:
, where x, y, z are the coordinates related to the vector.
Start with
Add 2x to both sides:
Subtract 21 from both sides:
Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:
So, the answer is
solution is: plus -2
Answer: -7
Step-by-step explanation: The sea level is at 0 so 0-7= -7
