Answer:
a) [tex][0,10]\cup[62,183][/tex], b) [tex][10, 62]\cup[183,+\infty][/tex], c) 3, d) Third-Order Polynomial, negative leading coefficient, e) [tex]t = 183\,s[/tex], f) [tex]2.81g[/tex]
Step-by-step explanation:
a) The intervals over which the acceleration is increasing are:
[tex][0,10]\cup[62,183][/tex]
b) The intervals over which the acceleration is decreasing are:
[tex][10, 62]\cup[183,+\infty][/tex]
c) There are three turning points.
d) The amount of turning points indicates the minimum degree of a polynomial function. The minimum model is a third-order polynomial. The leading coefficient must be negative, since acceleration decreases and turns negative as time goes by and higher degree means a major growth.
e) The greatest acceleration occurs at [tex]t = 183\,s[/tex].
f) The maximum acceleration is [tex]2.81g[/tex]
