- (a) P has degree 3, two local
maxima , and twolocal minima . - (b) P has degree 3 and no local maxima or minima.
- (c) P has degree 4, one
local maximum , and no local minima.
(a)
![Check Mark](/static/check-mark.png)
To check: The given statement is true or not.
Answer to Problem 4E
The given statement is not true.
Explanation of Solution
Given:
The polynomial P has 3 degree. The given polynomial has two local maxima and two local minima.
Calculation:
Let us consider a polynomial P of degree n.
Then the graph of P has at most
Local extrema is the points on the graph that has maximum and minimum value.
If a polynomial has 3 degree then the no of extrema is 2.
The given statement is that polynomial has 2 local maxima and 2 local minima that means there are 4 local extrema, but the polynomial have only 2 extrema.
Thus, the given statement is not true.
(b)

To check: The given statement is true or not.
Answer to Problem 4E
The given statement is true.
Explanation of Solution
Given:
The polynomial P has 3 degree. The given polynomial has no local maxima or minima.
Calculation:
Let us consider a polynomial P of degree n.
Then the graph of P has at most
Local extrema is the points on the graph that has maximum and minimum value.
If a polynomial has 3 degree then at most 2 local extrema, but there is no minimum number for local minima and maxima.
So, it may be possible that there should not be any local maxima or minima.
Thus, the given statement is true.
(c)

To check: The given statement is true or not.
Answer to Problem 4E
The given statement is true.
Explanation of Solution
Given:
The polynomial P has 4 degree. The given polynomial has one local maximum and no minima.
Calculation:
Let us consider a polynomial P of degree n.
Then the graph of P has at most
Local extrema is the points on the graph that has maximum and minimum value.
If a polynomial has 4 degree then at most 3 local extrema, but there is no minimum number for local minima and maxima.
So, it may be possible that there should one local maximum and no local minima.
Thus, the given statement is true.

- Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.arrow_forwardThe velocity of a particle moves along the x-axis and is given by the equation ds/dt = 40 - 3t^2 m/s.
