What is the equation of the circle with: center (5, 7) and point on the circle: (-2, 8)

Step-by-step explanation:

Hi there!

Equation of a circle: where the circle is centered at and r is the radius

Plug in the center (5,7)

Plug in the given point (-2,8) to solve for r²

Therefore, r² is equal to 50. Plug this back into

I hope this helps!

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
