Answer:

Step-by-step explanation:

For higher-degree polynomials I find it extremely useful to use a graphing calculator to find the zeros.

The usual approaches are ...

__

1. Rational roots will be factors of 10, so ±1, ±2, ±5, or ±10. The signs are all positive, so there are no positive real roots. The sum of odd-degree coefficients is the same as the sum of even-degree coefficients, so -1 is one of the roots. Removing that using synthetic division gives you ...

   f(x) = (x +1)(x^2 +11 +10)

The quadratic (more or less obviously) factors as (x+1)(x+10), so the complete factorization is ...

  f(x) = (x +1)^2(x +10)

and the zeros are {-10, -1, -1}.

__

2. Rational roots will be factors of 18, so will be ±1, ±2, ±3, ±6, ±9, ±18. The sum of coefficients is 0, so x=1 is a root. The rule of signs tells you that there are 2 positive real roots, so there is one more positive real root. Synthetic division tells you the factoring so far is ...

  f(x) = (x -1)(x^3 +2x^2 -9x -18)

We note that the first two coefficients have the same ratio as the last two, so we can factor by grouping.

  x^3 +2x^2 -9x -18 = x^2(x +2) -9(x +2) = (x^2 -9)(x +2)

Factoring the difference of squares gives you the complete factorization, hence all of the roots. (The zeros are the values of x that make the factors zero.)

  f(x) = (x -1)(x +2)(x -3)(x +3)

The zeros are {-3, -2, 1, 3}.

The points that are in the solution set of the given system of inequalities are (2, 0), (0, 2), and (0, 3).

a relationship between two expressions or values that are not equal to each other is called 'inequality.

To determine which point is in the solution set of the given system of inequalities, we need to check each point to see if it satisfies both inequalities.

A) (2, 0)

Plugging in the values of x=2 and y=0 into the inequalities, we get:

2+0 ≥ 2 which is true, and

4(2)+0 ≥ -1 which is true.

Therefore, point A (2, 0) is in the solution set of the given system of inequalities.

B) (0, 2)

Plugging in the values of x=0 and y=2 into the inequalities, we get:

0+2 ≥ 2 which is true, and

4(0)+2 ≥ -1 which is true.

Therefore, point B (0, 2) is in the solution set of the given system of inequalities.

C) (0, 3)

Plugging in the values of x=0 and y=3 into the inequalities, we get:

0+3 ≥ 2 which is true, and

4(0)+3 ≥ -1 which is true.

Therefore, point C (0, 3) is in the solution set of the given system of inequalities.

D) (0, -1)

Plugging in the values of x=0 and y=-1 into the inequalities, we get:

0+(-1) ≥ 2 which is false, and

4(0)+(-1) ≥ -1 which is false.

Therefore, point D (0, -1) is not in the solution set of the given system of inequalities.

Hence, the points that are in the solution set of the given system of inequalities are (2, 0), (0, 2), and (0, 3).

Step-by-step explanation:

%decrease = 1800 - 500 * 100

__________

1800

%decrease = 1300/1800 * 100

% decrease = 72.2%

Average attendance in 2003 = 1800

Average attendance in 2004 = 500

Decrease in attendance = 1800 - 500 = 1300

Decrease percentage in attendance

[tex] = \frac{1300}{1800} \times 100[/tex]

[tex] = \frac{13}{18} \times 100[/tex]

[tex] = \frac{13}{9} \times 50[/tex]

Answer:

x=19.5 or 19 1/2

Step-by-step explanation:

To find what x is we need to get x on one side of the equal sign with the numbers on the other side, but first, we need to add the same variables and numbers together.

Add:

4x+12=90

Move the 12 to the other side by subtracting 12 on both sides (You use the inverse of what you want to move to the other side)

4x+12-12=90-12

4x=78

Divide:

You need to divide 4x by 4 (Since 4x is the same thing as 4*x you need the inverse of multiplication to reverse it which is division)

x=19.5 or 19 1/2 (Since 1/2 is the same thing as 0.5)

i'll answer the question after you clarify for me,  if f(x) =-2x +3

then f (this is what you need to clarify for me please, theres 2 end parenthesis, but no start parenthesis and 2 numbers and 2 equal signs. what needs solved?)

Step-by-step explanation:

By looking at the table, we can see that the value for g(x) is always f(x)-1. Thus we can conclude that

[tex]g(x) = 4^x-1[/tex]

Now, think about the graph. For every value of y in f(x), the value of y in g(x) will be reduced by one. This means that the graph is translated down 1 unit!

The domain of both functions is actualy the same, that is, [tex]x\in\mathbb{R}[/tex].

However, the range won't be the same. As [tex]x[/tex] approaches negative infinity, the exponentials always approaches zero. Thus, f(x) has range between zero and positive infinity. But, for g(x), we are subtracting one unit from the Y values, therefore the range will be between negative one and positive infinity. In conclusion, their range is different.

Answer:

Company B

Step-by-step explanation:

Company A is the best investment decision. Why? its total probability of profit and breaking even is the greatest of all the three companies. Also, its the probability of making a profit is higher than that of making a loss.

The chance that a company will not make a loss is the sum of its break-even probability and that of its profitability. This probability for all companies is given below:

The probability of Loss is highest in Company B so this is not the best option.

The probability of profit is lowest in Company C so this is not the best option. Hence, A is the best investment decision.
