The zeros of this functions are -4, 2, -4, and -4.

-4 is a multiple zero and has multiplicity 3.

2 is a zero.  I would call it a simple zero, since it's only a zero once (AKA has multiplicity of 1).

Is this a "pick one answer" or "pick all correct answers"?

The number of electoral votes each state is assigned is determined by the size of its population every ten years. The chart show
sattari [20]

Answer:

D. Q_3=47

Step-by-step explanation:

We have been given a table that represents the the number of electoral votes California was assigned each decade of the past century. We are asked to find the 3rd quartile of our given data.

The number of votes are: 9, 13, 13, 22, 25, 32, 40, 45, 47, 54, 55.

We will use upper quartile formula to solve our given problem.

Q_3=\frac{3}{4}*(n+1)^{\text{th term}}, where, n represents the number of elements in the data set.

We can see that our data set has 11 data points, so upon substituting n=11 in above formula we will get,

Q_3=\frac{3}{4}*(11+1)^{\text{th term}}

Q_3=\frac{3}{4}*(12)^{\text{th term}}

Q_3=3*3^{\text{th term}}

Q_3=9^{\text{th term}}

Now let us count 9th term of our data set. Upon counting our data set from left to right we can see that 9th term of our data set is 47, therefore, 3rd quartile of our given data is 47 and option D is the correct choice.

2x^2 +5x+3/x^2+2x+1​
german

Answer:

\frac{2x+3}{x+1}

Step-by-step explanation:

2x² + 5x + 3 = (x + 1) (2x + 3)

x² + 2x + 1 = (x + 1) (x + 1)

(x + 1) cancels out because there is one in the denominator and the numerator, leaving you with the answer.

Hope this helps!
