Answer:

At x = 2 and 10.

Step-by-step explanation:

Given : The cost of producing x hundred items is given by the equation C(x) = x^2-3x + 7

The revenue generated from sales of x hundred units is given by the equation R(x) = -x^2 + 21x-33

To Find :What values of x will the company break even?

Solution:

Cost function : C(x) = x^2-3x + 7

Revenue function : R(x) = -x^2 + 21x-33

Now to find the company break even :

-x^2 + 21x-33= x^2-3x + 7

24x= 2x^2+40

12x= x^2+20

x^2-12x+20=0

x^2-10x-2x+20=0

x(x-10)-2(x-10)=0

(x-2)(x-10)=0

So, x = 2,10

Hence the company break even at x = 2 and 10.

Jose equation is -4(x+2) = 8x+16 says to jill “I can solve for the variable in this equation in at least 4 different ways
erastovalidia [21]

Answer:

that is step 1 and step 2 and step3

step 4

Let's solve your equation step-by-step.

−4(x+2)=8x+16

Step 1: Simplify both sides of the equation.

−4(x+2)=8x+16

(−4)(x)+(−4)(2)=8x+16(Distribute)

−4x+−8=8x+16

−4x−8=8x+16

Step 2: Subtract 8x from both sides.

−4x−8−8x=8x+16−8x

−12x−8=16

Step 3: Add 8 to both sides.

−12x−8+8=16+8

−12x=24

Step 4: Divide both sides by -12.

−12x

−12

=

24

−12

x=−2

Answer:

x=−2

A rectangular steel plate expands as it is heated. Find the rate of change of area with respect to temperature T when the width
trapecia [35]

Answer:

The variation rate is 4.07 × 10⁻⁵ cm²/ºC

Step-by-step explanation:

The relationship of the change in length as a function of the temperature, which are given in this problem can be written by the expression for the area of ​​a rectangle

a = L × W

Differentiating both sides,

\frac{da}{dT} = \frac{d(LW)}{dT}

\frac{da}{dT} = W \frac{dL}{dT} + L \frac{dW}{dT}

The values ​​they give us are

\frac{dL}{dT} = 1.1 × 10⁻⁵ cm/ºC

\frac{dW}{dT} = 8.9 × 10⁻⁶ cm/ºC

W = 1.6  cm

L= 2.6 cm

Substituting the values ​​and calculating

\frac{da}{dT} = (1.6 × 1.1 × 10⁻⁵) + (2.6 × 8.9 × 10⁻⁶)

\frac{da}{dT} = (1.76 × 10⁻⁵) + (2.31 × 10⁻⁵)

\frac{da}{dT} =  4.07 × 10⁻⁵ cm²/ºC

The variation rate is 4.07 × 10⁻⁵ cm²/ºC
