The height of the ball in metres is given as:

where xis time, in seconds.
At the instant that the ball is thrown, the time is 0 seconds. This means that the height will be h(0):

The height of the ball is 20 metres.
Answer: The answer is a polynomial in two variables with degree 3.
Step-by-step explanation: We are given to write the properties of the polynomial

We can see that the polynomial 'p' contains two unknown variables 'x' and 'y'.
Also, the degree of the polynomial is the degree of the expression 
Therefore, the degree of the polynomial will be 2 + 1 = 3.
Thus,
(i) the polynomial has two unknown variables 'x' and 'y', and
(ii) Its degree is 3.
