Answer:

5144

12

Step-by-step explanation:

The function p=x^2-24x+5000 is incorrect as its roots are imaginary b^2-4ac=576-4\times 5000=-19424.

So, the correct function is

p=-x^2+24x+5000

Differentiating with respect to x we get

p'=-2x+24

Equating with zero

0=-2x+24\\\Rightarrow x=\dfrac{24}{2}\\\Rightarrow x=12

Double derivative of the function

p''=-2

So, the function is maximum at x=12

Maximum profit is

p=-x^2+24x+5000=-12^2+24\times 12+5000\\\Rightarrow p=5144

The maximum profit made by the company is 5144

The number of clients required to make the maximum profit is 12.

Six times a number is at least four less than eight times the number. If x represents the number, which will help find the numbe
jeyben [28]

Answer:

The inequation 6x ≥ 8x - 4 can be used to find the solution.

The solution is x ≤ 2

Step-by-step explanation:

If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4

6x ≥ 8x - 4

Solving the inequation;

Subtracting 6x each side:

0 ≥ 8x - 6x -4

Summing 4 each side

4 ≥ 2x

Dividing by 2 each side

2 ≥ x

2 greater or equal than x is the same as:

x ≤ 2

C. -X to the 3rd power, 4x to the second power and 5x all share the common factor or X, therefore you put it outside the parenthesis. What you have left is -X to the second power minus 4x minus 5.

The slope f '(x) at each point (x, y) on a curve. y = f (x) is given along with a particular point (a, b) on the curve. Use this
Advocard [28]

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

            x^3          x^2

f(x) = 9--------- + 4------- - 4x + C

               3            2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.  

The solution is

            x^3          x^2

f(x) = 9--------- + 4------- - 4x - 7,   or   f(x) = 3x^3 + 2x^2 - 4x - 7

               3            2

Help someone please!! don’t understand
Citrus2011 [14]
Radical 2 = 1.4 So 1.4 * 6 = 8.4

a^2 + b^2 = c^2

8.4^2 + 8.4^2 = square root of c

70.56 + 70.56 = 141.12 ≈ 141

Then you must find the square root of 141 which is 11.874 ≈ 11.9

Side a = 8.4
Side b = 8.4
Side c = 11.9
