Answer: choice 1) 4

-----------------------------

Explanation:

The equation x^3+6x^2-x-10 = 0 is the same as 1x^3+6x^2-x-10 = 0
The first term is 1x^3 and the last term is -10
Pull away the coefficient of the first term and it is 1

Focus on the first coefficient (1) and the last term (-10)

List out the factors of each:
Factors of 1: -1 and 1
Factors of -10: -10, -5, -2, -1, 1, 2, 5, 10

Divide the factors of the last term (-10) over the factors of the first coefficient (1) to get...
-10/(-1) = 10
-10/(1) = -10
-5/(-1) = 5
-5/(1) = -5
-2/(-1) = 2
-2/(1) = -2
-1/(-1) = 1
-1/(1) = -1

10/(-1) = -10
10/(1) = 10
5/(-1) = -5
5/(1) = 5
2/(-1) = -2
2/(1) = 2
1/(-1) = -1
1/(1) = 1

The unique results we get are: -1, 1, -2, 2, -5, 5, -10, 10

So those are the possible rational roots of x^3+6x^2-x-10 = 0
This rules out choice 2, choice 3, choice 4. The only thing left is choice 1. 
The value 4 is not a possible rational root of x^3+6x^2-x-10 = 0

So that's why choice 1 is the answer

What are the period and amplitude of the function?
umka2103 [35]

Answer:

The period of function is 5 and amplitude is 3.

Step-by-step explanation:

<em>The period of the function is the time interval after which it repeats itself.</em>

It means the time interval after which the same value of graph is attained.

In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.

Thus the time interval is (10 - 5) 5 seconds.

<em>Amplitude is the maximum value attained by the graph in the complete interval.</em>

In the above case, the maximum value attained is 3.
