The average rate of change of g(x) between x=4 and x=7 is 5/6 which statement must be true

Δy = 15/6 = 5/2 = 2.5

Step-by-step explanation:

rate of change is slope so change in f(x) over shange in x

5/6 = Δy/7-4

5/6 = Δy/3

5/6*3/1 = Δy

Δy = 15/6 = 5/2 = 2.5

correct answer:

i^31 = -i

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
