7. mis the midpoint of qr and m has
coordinates (-2, 6). q has coordinates
(8, -10). what are the coordinates of r?
nges to the original content are the responsibility of the instructor.
i need on number 7

R(- 12, 22 )

Step-by-step explanation:

Using the midpoint formula

(8 + ) = = - 2

Multiply both sides by 2

8 + = - 4 ( subtract 8 from both sides )

= - 12

----------------------------------------------

(- 10 + ) = = 6

Multiply both sides by 2

- 10 + = 12 ( add 10 to both sides )

= 22

The coordinates of R = (- 12, 22 )

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
