Answer:

Step-by-step explanation:

Let's solve for c.

6c−9d=111

Step 1: Add 9d to both sides.

6c−9d+9d=111+9d

6c=9d+111

Step 2: Divide both sides by 6.

6c

6

=

9d+111

6c=3/2 d+37/2

Answer:

c= 3/2 d+37/2

Second one

Let's solve for c.

5c−9d=103

Step 1: Add 9d to both sides.

5c−9d+9d=103+9d

5c=9d+103

Step 2: Divide both sides by 5.

5c

5

=

9d+103

5c =9/5 d+103/5

Answer:

c=8, d = -7

Step-by-step explanation:

6c - 9d = 111

5c - 9d = 103

Multiply the second equation by -1

-5c + 9d = -103

Add this to the first equation to eliminate d

6c - 9d = 111

-5c + 9d = -103

------------------------

c        = 8

Now we need to find 9

6c - 9d = 111

Substitute in c=8

6(8) -9d = 111

48 - 9d = 111

Subtract 48 from each side

49-48 -9d = 111-48

-9d =63

Divide each side by -9

-9d/-9 = 63/-9

d = -7

Answer: therefore A= 0.1 and B=0.85

Step-by-step explanation:

The values of 'a' and 'b' in the frequency table are 0.1 and 0.1

We have,

To complete the conditional relative frequency table, we need to find the values of the letters 'a' and 'b'.

We know that the total for each row and column should add up to 1.

So, we can use this information to set up two equations and solve for the values of 'a' and 'b'.

Equation 1:

0.9 + b = 0.88

This equation represents the total percentage of students aged 16 years who finish homework before 10 pm.

We subtract 0.9 and 0.88 from both sides to get:

b = 0.88 - 0.9

b = -0.02

This means that the value of 'b' is negative, which doesn't make sense.

So, we made an error in setting up the equation.

We can check the table to find the correct value of 'b'.

We know that the total for the column "Before 10 pm" should be 1.

This means that the sum of the percentages 0.9 and 'b' should be equal to 1.

So,

Equation 2:

0.9 + b = 1

Solving for 'b', we get:

b = 1 - 0.9

b = 0.1

Now, we can use Equation 2 to solve for 'a':

0.15 + a = 0.12

Subtracting 0.15 from both sides, we get:

a = 0.12 - 0.15

a = -0.03

Again, we get a negative value for 'a', which doesn't make sense.

So, we need to check our work again.

We know that the total for the row "16 years" should be 1.

This means that the sum of the percentages 0.9 and 'a' should be equal to 1.

So,

0.9 + a = 1

Solving for 'a', we get:

a = 1 - 0.9

a = 0.1

Therefore,

The values of 'a' and 'b' in the frequency table are 0.1 and 0.1

Answer:

14.3€

Step-by-step explanation:

Let:

[tex]C=Price\hspace{3}of\hspace{3}the\hspace{3}shirt\\P=Price\hspace{3}of\hspace{3}the\hspace{3}pants\\T=Total\hspace{3}cost[/tex]

Now, let's write the data provided by the problem, using algebraic notation.

The total cost of the clothes is 20€, so:

[tex]P+C=T\\\\P+C=20[/tex]

The price of the shirt is :

[tex]C=\frac{2}{5} P[/tex]

Replacing this value into the first equation:

[tex]P+\frac{2}{5} P=20[/tex]

Solving for P:

[tex]\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3[/tex]

So, the price of the pants is 14.3€ and the price of the shirt is:

[tex]C+14.3=20\\\\C=20-14.3=5.7[/tex]

Translation:

Deja que:

[tex]C=Precio\hspace{3}de\hspace{3}la\hspace{3}camisa\\P=Precio\hspace{3}del\hspace{3}pantalon\\T=Costo\hspace{3}total[/tex]

Ahora, escribamos los datos proporcionados por el problema, usando notación algebraica.

El costo total de la ropa es de 20 €, entonces:

[tex]P+C=T\\\\P+C=20[/tex]

El precio de la camisa es:

[tex]C=\frac{2}{5} P[/tex]

Reemplazando este valor en la primera ecuación:

[tex]P+\frac{2}{5} P=20[/tex]

Resolviendo para P:

[tex]\frac{7}{5} P=20\\\\P=\frac{100}{7} \approx 14.3[/tex]

Entonces, el precio del pantalón es de 14.3 € y el precio de la camisa es:

[tex]C+14.3=20\\\\C=20-14.3=5.7[/tex]

The price of the pants is 14.3€ and the price of the shirt is: [tex]C+14.3=20\n\nC=20-14.3=5.7[/tex].

Let:

[tex]C=Price\hspace{3}of\hspace{3}the\hspace{3}shirt\nP=Price\hspace{3}of\hspace{3}the\hspace{3}pants\nT=Total\hspace{3}cost[/tex]

Now, let's write the data provided by the problem, using algebraic notation.

The total cost of the clothes is 20€, so:

P+C=T\n\nP+C=20

The price of the shirt is :

C=(2)/(5) P

Replacing this value into the first equation:

P+(2)/(5) P=20

Solving for P:

[tex](7)/(5) P=20\n\nP=(100)/(7) \approx 14.3[/tex]

So, the price of the pants is 14.3€ and the price of the shirt is:

[tex]C+14.3=20\n\nC=20-14.3=5.7[/tex].

               =0                                   elsewhere

where 0<p<1 and n is a positive integer.

Total number of toaster in cartons(n) = 10.

Probability of number of success on an individual trial p= 10% = 0.10

[tex]\therefore P(X=3)= C(10,3)(0.10)^3(1-0.10)^{10-3}[/tex]

                    [tex]=\frac{10!}{3!(10-3)!}(0.10)^3)(0.90)^7[/tex]

Height of the pole from the ground = 12 ft

Adjacent distance from the pole = 10 ft

We have to find the length of the rope attached by Scott to secure the pole.

According to the question :

In forma  right angled triangle as shown in the figure.

We have to find the measure of the hypotenuse.

Length of rope = Hypotenuse measure

Let the length of the rope = "h" ft

Using Pythagoras formula.

⇒ [tex](hypotenuse)=\sqrt{opposite^2+ adjacent^2}[/tex]

⇒ Plugging the values.

⇒ [tex]h=\sqrt{12^2 + 10^2}[/tex]

⇒ [tex]h=\sqrt{144 + 100}[/tex]

Question:

59 Revenue. The revenue (in dollars) from the sale of x infant car seats for infants is given by

R(x) =60·x - 0.025·x² 0 ≤ x ≤ 2400

(A) Find the average change in revenue if production is changed from 1,000 car seats to 1,050 car seats.

(B) Use the four-step process to find

(C) Find the revenue and the instantaneous rate of change of revenue at a production level of 1,000 car seats, and write a brief verbal interpretation of these results

Answer:

(A) $437.5

(B) R'(x) = 60 - 0.05·x

(C) $10

Step-by-step explanation:

(A) Here we have the change in revenue when production is increased from 1,000 car seats to 1,050 car seats is given as follows;

R(1050) - R(1000) = 60×1050 - 0.025×1050² - (60×1000 - 0.025×1000²)

R(1050) - R(1000) = 63000 - 27562.5 - 35000 = $437.5

(B) R'(x) is given by

Step 1. R(x + h) = 60·(x+h) - 0.025·(x+h)²

Step 2  R(x + h) - R(x) = 60·(x+h) - 0.025·(x+h)² -  60·x - 0.025·x² = [tex]-\frac{h^2+(2x-2400)h}{40}[/tex]

Step 3

[tex]\frac{R(x+h)- R(x)}{h} = -\frac{h^2+(2x-2400)h}{40 \times h} = -\frac{h +2x - 2400}{40}[/tex]

Step 4

[tex]\lim_{h \to 0} \frac{R(x+h)- R(x)}{h} = \lim_{h \to 0} -\frac{ h +2x - 2400}{40}[/tex]

∴  R'(x) = 60 - 0.05·x

(c) The revenue at a production level of 1000 car seats is

R(1000) = (60×1000 - 0.025×1000²) = $35,000

The instantaneous rate of change of revenue is given as follows

R'(x) = 60 - 0.05·x = 60 - 0.05×1000 = $10.

A) The average change in revenue when production is changed from 1,000 car seats to 1,050 car seats is $8.75. B) The derivative of the revenue function R1(x) with respect to x is R′1(x) = 60 - 0.05x. C) At a production level of 1,000 car seats, the revenue is $35,000 and the instantaneous rate of change of revenue is $10.

(A) To find the average change in revenue, we need to calculate the change in revenue and divide it by the change in the number of car seats produced. Let's calculate:

(B) To find R′1(x), we need to calculate the derivative of the revenue function R1(x) with respect to x. Let's differentiate:

R′1(x) = d/dx(60x - 0.025x2) = 60 - 0.05x

(C) At a production level of 1,000 car seats, the revenue is $35,000. The instantaneous rate of change of revenue (also known as the marginal revenue) at this production level can be found by substituting x = 1,000 into R′1(x):

R′1(1000) = 60 - 0.05(1000) = 60 - 50 = $10. The revenue at this production level is $35,000 and the instantaneous rate of change of revenue is $10, which represents the additional revenue obtained from producing one additional car seat.

Answer:

x^6 - (8/5)x^5 - 3x^3 + C.

Step-by-step explanation:

f(x) = 6x^5 - 8x^4 - 9x^2.

Using the general form antiderivative of Ax^m = Ax(m+1) / (m+1)+ C:

Antiderivative = 6 * x^(5+1) / 6 - 8 * x^(4+1) / 5 - 9 * x^(2+1) / 3 + C

=  6x^6/6  - 8x^5/5 - 9x^3/3 + C

= x^6 - (8/5)x^5 - 3x^3 + C.

Differentiating:

f'(x) = 6x^(6-1) - 8 x^(5-4) - 9x^(3-1) + 0

f'(x) = 6x^5 - 8x^4 - 9x^2.

The most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2 is F(x) = x^6 - 8/5 * x^5 - 3x^3 + C, where C is the constant of the antiderivative.

To find the most general antiderivative of the given function f(x) = 6x5 − 8x4 − 9x2, we need to perform the process of integration, which is the reverse of differentiation. The antiderivative F(x) will be found by integrating each term of the function separately.
The antiderivative of f(x) will then be:  

F(x) = ∫6x5 dx - ∫8x4 dx - ∫9x2 dx,

Transitioning to the next step by applying the power rule for integration, we add 1 to the exponent and divide by the new exponent, we obtain

F(x) = 6/6 * x^(5+1) - 8/5 * x^(4+1) - 9/3 * x^(2+1) + C

Simplified, the antiderivative F(x) becomes:  

F(x) = x^6 - 8/5 * x^5 - 3x^3 + C,

where C is the constant of the antiderivative.
