EXTREAMLY URGENT WhAT is the distance formula for the distance between points K and L?

Step-by-step explanation:

The distance formula for (x, y, z) is the same as the distance formula for (x, y), but with just one more added variable:

If that is the case, we just plug in x, y, and z. But wait, we are missing point K coordinates. Simple enough. Point K is just a translation of point L by moving to the left. That means the coordinates are the same except for x, which will be -3 (so the coordinates would be (-3, 3, -3)). That just leaves us to plug it into the equation:

Simplifying it down gives you the answer in the answer. If you want to find an exact value, simply plug it into the calc. That will give you d = 3.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
