Determine the equation of a circle with a center at (-4, 0) What is the equation of a circle with a center at (-4, 0)
that passes through the point (-2, 1) by following the that passes through the point (-2, 1)?
steps below.
x2 + (y + 4) =
1. Use the distance formula to determine the radius:
d = x2-x,)? +(y2-)?.
(x - 1)2 + (y + 2)2
(x + 4)2 + y² = 5
2. Substitute the known values into the standard form:
(x - h)2 + (y - k) = 1
(x + 2)2 + (y - 1)2 = 5

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
