An electric household current can be modelled by , where V is the voltage, in volts, and t is the time, in seconds. The electric field is the negative derivative of the voltage. Determine a formula for the electric field (EF).

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest

the answer is that it is true
