Find the midpoint of the line segment joining the points r(1,4) s(-3,7)

We can find the midpoint by finding the average between the two points.

We have r(1, 4) and s(-3, 7).

The formula for midpoint is .

Let's plug in 1 and -3 in and plug in 4 and 7 in .

Simplify the top numbers so now we have:

Simplify even further and now we have:

-1, 11/2

So the midpoint of the line segment is (-1, 11/2).

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
