Selections 2, 3, 5, 6 are polynomials.
1 and 4 are not. The coefficients don't have to be integers, but the powers of the variables need to be positive integers. In 1, you have x^-1. in 4, you have x^(1/2).
Answer:
any order where 2 is the last number in the sequence
Step-by-step explanation:
the ten-thousand place in 12,345 is 5.
ex: 3,8,9,5,2
5,9,8,3,2
8,9,5,3,2
For this case we have an equation of the form:

Where,
h0: initial height
v0: initial speed
a: acceleration
Substituting values we have:

Rewriting we have:
