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.
