Answer:

9(5 + 8)

Step-by-step explanation:

To solve the radical equation √4z²-13z+9+3=3z, we need to get rid of the radical sign in order to isolate the variable.

First, we can add 9 to both sides to get:

√4z²-13z+12=3z+9

Then we can square both sides of the equation:

4z²-13z+12 = 9z²+27z+81

Now, we can rearrange the equation to get:

9z²-40z+69 = 0

Now we can use the quadratic formula to find the solutions for z:

z = (40 ± √(40²-4969)) / 2*9

z = (40 ± √(1600-2772)) / 18

z = (40 ± √(-1172)) / 18

Since the square root of a negative number is an imaginary number, this equation has no real solutions, which means that there are no values of z that will make the equation true.

So the radical equation √4z²-13z+9+3=3z doesn't have any solution.

Product A: $8 (loss),

Product B:  $16 (loss),

Product C: $10 (profit),

Product D: $9 (profit),

Product E: $8 (profit).

The sum of the quantities divided by the total value of purchases and sales yields the unit value of a group of similar goods. As a result, it represents a quantity-weighted average of the various prices at which the good is bought and sold.

Given inventory,

                      Product Cost               Selling Price

A                            $130                          $150

E                               $50                         $70

a sales commission equal to 10% of the selling price and shipping costs equal to 10%,

Product A :

the unit value is given by,

Value = selling price - (product cost + sales commission + shipping cost)

= $150 - ($130 + 10% x selling price + 10% x product cost)

= $150 - ($130 + 10% x $150 + 10% x $130)

= $150 - ($130 + $15 + $13)

= -$8 = $8 (loss)

Product B :

Value = selling price - (product cost + sales commission + shipping cost)

= $190 - ($170 + 10% x selling price + 10% x product cost)

= $190 - ($170 + 10% x $190 + 10% x $170)

= $190 - ($170 + $19 + $17)

= -$16 = $16 (loss)

Product C :

Value = selling price - (product cost + sales commission + shipping cost)

= $170 - ($130 + 10% x selling price + 10% x product cost)

= $170 - ($130 + 10% x $170 + 10% x $130)

= $170 - ($130 + $17 + $13)

= $10 = $10 (profit)

Product D :

Value = selling price - (product cost + sales commission + shipping cost)

= $120 - ($90 + 10% x selling price + 10% x product cost)

= $120 - ($90 + 10% x $120 + 10% x $90)

= $120 - ($90 + $12 + $9)

= $9 = $9 (profit)

Product E :

Value = selling price - (product cost + sales commission + shipping cost)

= $70 - ($50 + 10% x selling price + 10% x product cost)

= $70 - ($50 + 10% x $70 + 10% x $50)

= $70 - ($50 + $7 + $5)

The inverse demand function is P = 2400 + 5Q

Given that

Q = 480 - 0.2P

We simply make P the subject of the formula

So, we have

0.2P = 480 - Q

Divide by 0.2

P = 2400 + 5Q

To find the marginal revenue function, we can use the inverse demand function P = 2400 + 5Q, and take the derivative of this function with respect to Q.

The derivative of P with respect to Q is dP/dQ = 5. This represents the change in price for a one unit change in the quantity of operations performed.

So the Marginal Revenue function is MR = dP/dQ * Q = 5Q

To maximize profit, the doctor should equate marginal revenue to marginal cost, which is

MC = dAVC/dQ

So, we have

MC = d(2Q² - 15Q + 400)/dQ

Evaluate

MC = 4Q - 15.

So, we have

5Q = 4Q - 15

Q = -15

Take the absolute value

Q = 15

So, the number of operations is 15

We have

P = 2400 + 5Q

This gives

P = 2400 + 5 * 15

Evaluate

P = 2475

To find the profit, we need to subtract the total cost from the total revenue.

The total revenue is found by multiplying the price by the quantity of operations performed: TR = P * Q = 2475 * 15 = 37125

The total variable cost is found by multiplying the average variable cost by the quantity of operations performed: TVC = AVC * Q = (2Q^2 - 15Q + 400) * Q = 2Q^3 - 15Q^2 + 400Q

The total fixed cost is the fixed cost that doesn't change regardless of the level of output : TFC = $8000

The total cost is the sum of the total variable cost and total fixed cost: TC = TVC + TFC = 2Q^3 - 15Q^2 + 400Q + $8000

The profit is the difference between total revenue and total cost:

π = TR - TC = 37125 - (2Q^3 - 15Q^2 + 400Q + $8000)

When Q = 15,

profit is π = 37125 - (2(15)^3 - 15(15)^2 + 400(15) + $8000)

An a non real solution uses non real numbers to solve the equation, which cannot be solved with real numbers. Back to the school answer: A non-real solution to a math equation is a solution that has “imaginary numbers” (also called “complex numbers”) in it because it cannot be solved with real numbers.

Step1

We need to find equation that has exactly two real and two non real solutions

2 real  and 2 non real solution means 4 solutions

x³ equation has maximum of 3 solutions

So we ignore equation that has largest exponent x³

We ignore options B  and D

Let check option A

x⁴ 36x² =0

factor the left hand side

Factor out x^2

x² (x² -36)=0

WE set each factor =0  and solve for x

x² =0  so x=0

x²  - 36 =0 so x= +-6

So solutions are x=0, x=6 , x= -6. Only 3 real solutions we got

LETS check with option C

x⁴  - 5x² -36=0

Factor left hand side

(x² -9)(x² +4)=0

set each factor =0  and solve for x

x² -9 =0  so x= -3, + 3

The volume of the solid is 32/3.

The volume of the solid whose base is bounded by the circle x2 + y2 = 4 and the cross sections perpendicular to the x-axis are squares can be calculated using the formula for the volume of a solid of revolution. This formula states that the volume is equal to the integral of the area of the cross sections from the lower limit to the upper limit.

Since the cross sections are squares, the area of each cross section is given by the equation A = x2. The lower limit is given by the equation x2 + y2 = 4, which is x=-2, and the upper limit is x=2. Thus, the volume is given by the integral ∫(-2)2x2dx = 8∫x2dx = 8(x3/3)|(-2)2 = 8(2^3/3 - (-2)^3/3) = 8(8/3 - -8/3) = 32/3. Therefore, the volume of the solid is 32/3.

c) Given that the boy thinks he chose a blue pen, there is a 96% probability that he actually chose a blue pen.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The following probabilities are given -

A 75% probability that a pen is blue.

A 25% probability that a pen is green.

If a pen is blue, an 80% probability that the boy thinks it is a blue pen.

If a pen is blue, a 20% probability that the boy thinks it is a green pen.

If a pen is green, a 90% probability that the boy thinks it is a green pen.

If a pen is green, a 10% probability that that the boy thinks it is a blue pen.

a) The probability that the boy picks up a blue pen and recognizes it as blue.

There is a 75% probability that he picks up a blue pen.

There is a 80% probability that he recognizes a blue pen as blue.

So, the equation will be -

P = 0.75 × 0.8

P = 0.6

Therefore, there is a 60% probability.

b) The probability that the boy chooses a pen and thinks it is blue.

There is a 75% probability that he picks up a blue pen.

There is a 80% probability that he recognizes a blue pen as blue.

There is a 25% probability that he picks up a green pen

There is a 10% probability that he thinks a green pen is blue.

So, the equation will be -

P = (0.75 × 0.80) + (0.25 × 0.10)

P = 0.6 + 0.025

P = 0.625

Therefore, there is a 62.5% probability.

c) Given that he thinks he chose a blue pen, the probability that he actually chose a blue pen.

There is a 62.5% probability that he thinks that he choose a blue pen.

There is a 60% probability that he chooses a blue pen and think that it is blue.

So, the equation will be -

P = 0.6/0.625

P = 0.96
