Suppose that the price per unit in dollars of a cell phone production is modeled by p=55−0.0125x, where x is in thousands of pho

nes produced, and the revenue represented by thousands of dollars is R=x⋅p. Find the production level that will maximize revenue.

Answer: At x = 2200 level of production, it will get maximum revenue.

Step-by-step explanation:

Since we have given that

p = 55-0.0125x

and Revenue function is given by

R=x.p\\\\R=x(55-0.0.125x)\\\\R(x)=55x-0.0125x^2

We will take the first derivative of it.

R'(x)=55-0.025x

Now,we will find the critical points :

55-0.025x=0\\\\0.025x=55\\\\x=\dfrac{55}{0.025}\\\\x=2200

and R''(x)=-0.025<0, so it will get maximum revenue.

Hence, At x = 2200 level of production, it will get maximum revenue.

The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car. The auto repair shop on Second A
Lilit [14]

Answer:

3 hours

Step-by-step explanation:

Let's express number of hours required for servicing as: x

The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car.

This is expressed mathematically as:

$15 + $10 × x

= 15 + 10x

The auto repair shop on Second Avenue charges no flat fee but $15 an hour for servicing a car

This is expressed as:

$15 × x

= 15x

The number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at both shops is calculated as:

Charges by Auto repair shop on First street = Charges by Auto repair shop on Second Avenue

15 + 10x = 15x

15 = 15x - 10x

15 = 5x

5x = 15

x = 15/5

x = 3 hours

Therefore, the number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at either auto repair shops is 3 hours

I really need help with this fast!!
ss7ja [257]

Answer:

Hello. y=1/2x-2

Step-by-step explanation:

The line that is perpendicular to this line ،its slope must be 1/2

So:

y - y0 = m(x - x0) \\ y - 2 =  \frac{1}{2} (x - 8)  \\ y =  \frac{1}{2} x  - 2

Rewrite the equation by completing the squares x^2-x-20
yuradex [85]

Answer:  x = ¹/₂ ± √⁸¹

                     ------------

                            2

Step-by-step explanation:

First write out the equation

x² - x - 20

Now we now write the equation by equating to 0

x² - x - 20 = 0

We now move 20 to the other side of the equation. So

x² - x    =  20,

We now add to both side of the equation square of the half the coefficient of the (x) and not (x²) which is (1) . So, the equation now becomes

x² - x + ( ¹/₂ )² = 20 + ( ¹/₂ )²

x² - ( ¹/₂ )²       = 20 + ¹/₄

( x - ¹/₂ )²       = 20  + ¹/₄, we now resolve the right hand side expression into fraction

( x - ¹/₂ )²          =  ⁸¹/₄ when the LCM is made 4

Taking the square root of both side to remove the square,we now have

x - ¹/₂               =  √⁸¹/₄

x - ¹/₂               =     √⁸¹/₂

Therefore,

                    x = ¹/₂ ± √⁸¹

                          -----------

                               2
