Question

Applications of Parabolar-Projectile motion. An object which is thrown or projected into the

Answer 1

Answer:

a) iii. 2

b) ii. 81.2 m

c) iv. Trinomial

d) iii. Quadratic polynomial

Explanation:

Polynomial is an expression consisting of variables and coefficients, involving operations of addition, subtraction, multiplication.

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

Given the polynomial:

P(t)=-5t² + 40t + 1.2

Where t is the time and P(t) is the distance covered.

a) The degree of the polynomial is 2.

b) At t = 4:

P(4)= -5(4)² + 40(4) + 1.2 = 81.2 m

c) Since the polynomial has 3 terms, i.e. (-5t², 40t and 1.2). Hence the polynomial is a trinomial

d) The polynomial have a degree of 2, hence it is a Quadratic polynomial.
