An entrepreneur estimates that the total profit (profit = total revenue minus total cost) from his proposed company will be give
Studentka2010 [4]
I found the same problem but with given choices:
A.1 year 
<span>B.2 years </span>
<span>C.3 years </span>
<span>D.4 years </span>
<span>E.6 years
</span>
profit = total revenue - total cost
p(x) = x³ - 4x² + 3x - 12

simply plug each choices to solve. answer must be 0.

A) p(1) = 1³ - 4(1²) + 3(1) - 12 = 1 - 4 + 3 - 12 = -12
B) p(2) = 2³ - 4(2²) + 3(2) - 12 = 8 - 16 + 3 - 12 = -17
C) p(3) = 3³ - 4(3²) + 3(3) - 12 = 27 - 36 + 9 - 12 = -12
D) p(4) = 4³ - 4(4²) + 3(4) - 12 = 64 - 64 + 12 - 12 = 0
E) p(6) = 6³ - 4(6²) + 3(6) - 12 = 216 - 144 + 18 - 12 = 78

It would take 4 years for the company to reach break-even point.

Use the quadratic formula to complete the table. To verify your solutions, graph the equations.
Anna007 [38]

Answer:

1) Value of Discriminant: -32

Solution Value(s):

x = -2/3 + 2√2i/3

x = -2/3 - 2√2i/3

2) Value of Discriminant: -44

Solution Value(s):

x = -1/3 + √11i/3

x = -1/3 - √11i/3

Step-by-step explanation:

The Discriminant is the part of the Quadratic Formula that is under the square root symbol.

If the Discriminant > 0 there are 2 real solutions.

If the Discriminant = 0 there is 1 real solution.

If the Discriminant < 0 there are 2 imaginary solutions.

Equation 1:

3x² + 4x + 4 = 0

Plug this into the Quadratic Formula and solve:

x = -4 ± √-32 all over 6

Value of Discriminant: -32

Obviously, this can be simplified more, but for now, all you need is what is under the square root. Since it is less than 0, there are going to be 2 imaginary solutions.

Continue simplifying to get to the Solution Values. You will end up here:

x = -2/3 ± 2√2i/3

Your two imaginary solutions are:

x = -2/3 + 2√2i/3

x = -2/3 - 2√2i/3

*Note: 2√2i is ALL over 3, not just the √2i*

You can convert this to decimal if you need (but I don’t suggest it):

x = -0.66666 + 0.942809i

x = -0.66666 - 0.942809i

Equation 2:

3x² + 2x + 4 = 0

Plug this into the Quadratic Formula and solve:

x = -2 ± √-44 all over 6

Value of Discriminant: -44

Obviously, this can be simplified more, but for now, all you need is what is under the square root. Since it is less than 0, there are going to be 2 imaginary solutions again.

Continue simplifying to get to the Solution Values. You will end up here:

x = -1/3 ± √11i/3

Your two imaginary solutions are:

x = -1/3 + √11i/3

x = -1/3 - √11i/3

You can convert this to decimal if you need (but I don’t suggest it):

x = -0.33333 + 1.10554i

x = -0.33333 - 1.10554i

Hope this helps!

In how many ways can president, vice-president, and secretary be chosen from 9 students?
Dominik [7]

Answer:

The answer is 27

Step-by-step explanation:

This is because each person can have up to three roles, and there are 9 students. So you can form an array, or a table to show your values. so if you have 9 rows and 3 coulombs and you can have 27 crosses in the array.
