What is the solution of the inequality x^2-9x+18 less then or equal to zero? graph solution.

ANSWER

EXPLANATION

The given inequality is

This is the same as

The corresponding equation is

By the zero product principle,

We now plot the boundaries and test for the region that satisfies the inequality.

See attachment.

From the graph the solution is

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
