HELP PLEASE 20 POINTS

390

Step-by-step explanation:

We need to find the slope of the data

m = (y2-y1)/(x2-x1)

    = (90-60)/(4-2)

    =30/2

    = 15

y = 15x +b

Let (10,180) =x,y

180 = 15*10 +b

180 = 150+b

Subtract 150 from each side

180-150 =150+b-150

30=b

The equation is y = 15x+30

We want to rent it for 24 hours

y = 15*24 +30

360+30

y = 390

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
