what is f(x) = 0,5 (x-3)( x-5) in general form??​

Answers

Answer 1

Answer:

[tex]f(x)=0.5x^2-4x+7.5[/tex]

Step-by-step explanation:

The general form of a quadratic function is:

[tex]y=ax^2+bx+c[/tex]

We'll find the general form of the function:

[tex]f(x)=0.5(x-3)(x-5)[/tex]

Multiplying the expressions in parentheses:

[tex]f(x)=0.5(x^2-5x-3x+15)[/tex]

Simplifying:

[tex]f(x)=0.5(x^2-8x+15)[/tex]

Operating:

[tex]\mathbf{f(x)=0.5x^2-4x+7.5}[/tex]

A division of Chapman Corporation manufactures a pager. The weekly fixed cost for the division is $14,000, and the variable cost for producing x pagers/week in dollars is represented by the function V(x). $ V(x) = 0.000001x^3 - 0.01x^2 + 50x $ The company realizes a revenue in dollars from the sale of x pagers/week represented by the function R(x). $ R(x) = -0.02x^2 + 150x \; \quad \; (0 \leq x \leq 7500) $ (a) Find the total cost function C. What is the profit for the company if 2,600 units are produced and sold each week?

Answers

Answer:

P=$-303,424

Step-by-step explanation:

given data

fixed cost= $14,000

variable cost function

[tex]V(x) = 0.000001x^3 - 0.01x^2 + 50x[/tex]

revenue function

[tex]R(x) = -0.02x^2 + 150x \; \quad \; (0 \leq x \leq 7500)[/tex]

a. we know that total cost C=fixed cost plus variable cost

C=14000+0.000001x^3 - 0.01x^2 + 50x

[tex]C=14000+0.000001x^3 - 0.01x^2 + 50x[/tex]

profit is given as revenue minus the total cost

P=R(x)-C   (x=2600)

[tex]P=-0.02x^2 + 150x -(14000+0.000001x^3 - 0.01x^2 + 50x)[/tex]

substitute x=2600

[tex]P=-0.02(2600)^2 + 150(2600) -(14000+0.000001(2600)^3 - 0.01(2600)^2 + 50(2600))[/tex]

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59 (add 11 on both sides)

m = -48

Hope this helps!!

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59

you add the 11 to both sides crossing it out from the left side and then you get an equation that looks like this.

m = -59 + 11

find 2 consecutive integers whose sum is -97

Answers

Answer:

The first integer is: -49

The second integer: -49+1 = -48

Solution Check:

-49+(-48) = -97

Step-by-step explanation:

Let the first integer: [tex]x[/tex]

As we are looking for a consecutive integer, so

The second integer would be: [tex]x+1[/tex]

We know the sum of these two integers is -97. Thus, we can write this equation and solve for 'x'.

[tex]x+\left(x+1\right)=-97[/tex]

[tex]x+x+1=-97[/tex]

[tex]2x+1=-97[/tex]

[tex]2x=-98[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{-98}{2}[/tex]

[tex]x=-49[/tex]

Therefore,

The first integer is: -49

The second integer: -49+1 = -48

Solution Check:

-49+(-48) = -97

Each year, Andrea donates a total of $800 for scholarships at her local community college. This year, she wants the amount she donates for liberal arts to be three

times the amount she donates for scholarships for business. Determine the amount she will donate for each type of scholarship.

The equation is Andrea will donate $ for business scholarships and $ for liberal arts scholarships.

Answers

Answer:

The equation is [tex]L + B = \$800[/tex]

Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.

Step-by-step explanation:

Given

Represent Liberal Arts with L and Business with B

From the question, we have that:

[tex]L = 3 * B[/tex]

and

[tex]Total = \$800[/tex]

Required

Determine how much she donates for each

The total L + B is 800

i.e.

[tex]L + B = \$800[/tex]

Substitute 3 * B for L

[tex]3 * B + B = \$800[/tex]

[tex]3 B + B = \$800[/tex]

[tex]4B = \$800[/tex]

Solve for B

[tex]B =\$800/4[/tex]

[tex]B =\$200[/tex]

Recall that :

[tex]L = 3 * B[/tex]

[tex]L = 3 * \$200[/tex]

45 does not go into 285 evenly.
The quotient contains a repeating decimal.
The quotient contains a terminating decimal.
The quotient is 6.ModifyingAbove 3 with bar.
The quotient is 6.3.

Answers

Answer:

Step-by-step explanation:

The true statements are:

45 does not go into 285 evenly.

The quotient is 6 with a remainder of 15.

Here,

To divide 285 by 45, we perform the division:

  6

-------

45 | 285

  - 270

  -------

     15

The quotient is 6 with a remainder of 15.

Now, let's analyze the statements:

45 goes into 285 evenly. - False.

45 does not divide 285 evenly since there is a remainder of 15.

45 does not go into 285 evenly. - True.

As explained above, 45 does not divide 285 evenly, and there is a remainder of 15.

The quotient contains a repeating decimal. - False.

There is no repeating decimal in the quotient since the division is a whole number (6).

The quotient contains a terminating decimal. - False.

As mentioned earlier, there are no decimals involved in the quotient; it's a whole number.

The quotient is 6 with a bar above 3. - False.

The quotient is 6 with a remainder of 15, not 6.3.

In summary, the true statements are:

45 does not go into 285 evenly.

The quotient is 6 with a remainder of 15.

D. 2:5

Answers

Answer:

A. 5:6

Step-by-step explanation:

The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.

Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.

Therefore:

Scale factor = 25:30
