Find the midpoint of the segment with the following endpoints.<br> (-3,6) and (3, 0)
otez555 [7]

The midpoint of the segment with endpoints (-3,6) and (3, 0) is (0, 3)

<h3>Midpoint of a line </h3>

From the question, we are to determine the midpoint of the segment with the given endpoints

The given endpoints are

(-3,6) and (3, 0)

Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is

((x₁+x₂)/2, (y₁+y₂)/2)

Thus,

The midpoint of the line with the endpoints (-3,6) and (3, 0) is

((-3+3)/2, (6+0/2)

= (0/2, 6/2)

= (0, 3)

Hence, the midpoint of the segment with endpoints (-3,6) and (3, 0) is (0, 3)

Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles
Angelina_Jolie [31]

40(1.25-t) is missing from the table

Time, speed, and distance are the three factors must be taken into account.

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed X Time

We provide both time and speed.

It is necessary to compute the distance.

55 miles per hour is the commuter speed

Worktime equals 1.25-T

Home-bound speed is 40 miles per hour.

1.25 seconds to get home

Time in Total = T + t = 1.25

Travel distance to home

Distance/Time x Speed

40 = Total Distance/t

Distance overall = 40 (1.25-t)

As a result, 40(1.25-t) is the right response.
