Classify the following into monomials, binomial and trinomials.

Degger [83]

A monomial is an expression containing a single term.
A binomial is an expression having two terms.
A trinomial is an expression having three terms.

Here -6 is a monomial having a single term -6.
-5 + x is a binomial containing two terms -5 and x.
32x - y is a binomial having two terms 32x and -y.
6x² + 5x - 3 is a trinomial having three terms 6x², 5x and -3.
z² +2 is a binomial having two terms z² and 2.

Answer:

a) The vertex of the graph is $(h,k) = (0, 31)$ , b) $a = -16$ , c) The equation of the parabola is $f(t) = -16\cdot t^{2}+31$ .

Step-by-step explanation:

a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.

The vertex of the graph is $(h,k) = (0, 31)$ .

b) If we know that $(h,k) = (0, 31)$ , $f(t) = a\cdot (t-h)^{2} + k$ and $(t,f(t)) = (1,15)$ , then the value of $a$ is:
