Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.
A.
. The result is still a polynomial; therefore, answer A is incorrect.
B.
with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.
C.
. The result is still a polynomial; therefore, answer C is incorrect.
D.. The result is still a polynomial; therefore, answer D is incorrect.

D.
Answer:
Step-by-step explanation:
The above question is in the form of an exponential decay. The equation for an exponential decay is given by:
where y and x are variables, b < 1, a is the initial value of y (that is the value of y when x = 0).
Let y represent the number of trees left and x represent the number of months. Given that there is currently 2.5 billion trees, therefore a = 2.5 * 10⁹, b = 0.5% = 0.005. The equations becomes:
