==================================

The Millau Viaduct, at 1125 ft, is the highest bridge in the world and overlooks the river Tarn in France. An object is dropped from the top of the bridge. Neglecting air resistance, the height of the object at time t seconds is given by the polynomial function P(t) = -16t2+ 1125. Find the height of the object when t = 6 seconds.

933 ft.

1177 ft.

549 ft.

1317 ft.

Adding and Subtracting Polynomials

Which term best describes the expression?

There are 3 terms in the polynomial (a term is a part that is added or subtracted), so this

is a trinomial.

monomial

binomial

trinomial

not a polynomial

==========================

What is the degree of the term below?

5x3

The degree of a polynomial is the highest exponent. If there is multiple variables, then

the degree is the term with the highest sum of the exponents.
