Final answer:
The total number of elements in vector P can be determined by calculating the range between the start and end points of the vector, and then dividing that range by the step size. In this case, there are 5 elements in vector P.
Step-by-step explanation:
The total number of elements in vector P, represented by the expression P = linspace(2,10,5), can be determined by calculating the range between the start and end points of the vector, and then dividing that range by the step size. In this case, the range is 10 - 2 = 8, and the step size is (8 / (5-1)) = 2. Therefore, there are 5 elements in vector P.
