Answer:
The coordinates of the midpoint of the two vertices are
(0,2) (Third option)
Step-by-step explanation:
<u>Coordinates Of A Midpoint
</u>
Given a pair of points in the plane

the coordinates of the midpoint of both points are


The vertices given in the figure are

So the x-coordinate of their midpoint is

And the y-coordinate of their midpoint is

So the coordinates of the midpoint of the two vertices are
(0,2), the third option

Answer:
67.5
Step-by-step explanation:
- When you calculate the 10% of AED75, it is equal to AED7.5
- Then you subtract AED7.5 from AED75 which is AED67.5
The formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid is p = s + dgh, where s is the atmospheric pressure, d is the density of the liquid, and gas the acceleration due to gravity.
p = s + dgh
dgh = p - s
h = (p - s)/dg
Which formula represents h in terms of p, s, d, and g? Formula B is correct.

A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
