Given below is the odd-number function. which of the following are equal to o(20)? check all that apply. o(n) = 2n - 1 a. o(19) + 1 b. the twentieth odd number c. 39 d. 19

In order for us to determine the value of O(20), we just have to substitute 20 to the n’s of the function.

                                                O(n) = 2n – 1

Substituting,

                                              O(20) = 2(20) – 1= 39

Thus, the answer is letter C. It should be noted also that this is also the 20th odd number, so letter B is also acceptable. 

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
