(c) If a plane travels at x-110 mph for 3.5 hr, write an expression that represents the distance traveled. The expression that represents the distance traveled is mi. X

Answers

Answer 1

Answer:

Step-by-step explanation:

The distance traveled by the plane can be represented by the expression: distance = speed x time

In this case, the speed of the plane is given as x-110 mph and the time it travels is 3.5 hours.

So the expression for the distance traveled is:

distance = (x-110) * 3.5 miles

This expression represents the distance traveled in miles. The variable x represents the speed of the plane in mph.

Answers

Answer:

a) e^x (3 - e^x)^4 dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

e^x (3 - e^x)^4 dx = (e^x)^5 (3 - e^x)^4 / 5 + c

= (e^5x - 4e^4x + 6e^3x - 4e^2x + e^x) / 5 + c

b) 3e^2x √(1 + e²x) dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

3e^2x √(1 + e²x) dx = (3e^2x)^2 * (1 + e²x)^(3/2) / 2 + c

= (9e^4x + 3e^2x) / 2 + c

c) 3e^-2x / (1 + e^-2x)^3 dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

3e^-2x / (1 + e^-2x)^3 dx = -(3e^-2x)^2 / (1 + e^-2x)^2 + c

= -(9e^-4x) / (e^-4x + 2e^-2x + 1) + c

d) 4 cos 2x sin³ 2x dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

4 cos 2x sin³ 2x dx = -4 cos 2x (sin 2x)^4 / 4 + c

= -(cos 2x) (1 - cos 4x)^2 / 2 + c

e) sec² 3x tan³ 3x dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

sec² 3x tan³ 3x dx = -sec² 3x (tan 3x)^4 / 4 + c

= -sec² 3x (sec² 3x - 1)^2 / 4 + c

f) 2+tan ² x / cos² x dx

Using the formula [ f'(x)[f(x)"]dx =[ [f(x)]^n+1 / n+1] + c, where n = 1,

we have:

2+tan ² x / cos² x dx = ln|sec x| + c

It's worth noting that all these integrals are indefinite, which means that the constant c is arbitrary, and the actual antiderivative depends on the problem context.

The area of the shaded region is obtained as (π/√2) units².

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The diagram is labelled.

The values for area of z and y needs to be obtained.

The result will be in the form |y| + z as when the integration will be done, y will come out to be negative.

Now, x + z is the area of rectangle ABCD.

Verify whether x and y are equal in magnitude -

[tex]\begin{aligned}& x=\int_{\frac{\pi}{4}}^{\frac{\pi}{2}} \frac{\cos \theta}{\sin ^2 \theta} d \theta=\left[\frac{-1}{\sin \theta}\right]_{\frac{\pi}{4}}^{\frac{\pi}{2}} \\& =-1-(\sqrt{2}) \\& =\sqrt{2}-1\end{aligned}[/tex]

[tex]\begin{aligned}& y=\int_{\frac{\pi}{2}}^{\frac{3\pi}{4}} \frac{\cos \theta}{\sin ^2 \theta} d \theta=\left[\frac{-1}{\sin \theta}\right]_{\frac{\pi}{2}}^{\frac{3\pi}{4}} \\& =-(\sqrt{2})-(-1) \\& =-\sqrt{2}+1\end{aligned}[/tex]

This is equal to |y| = x.

So, |y| + z is equivalent to writing x + z.

Now the formula for area of rectangle ABCD is -

Area = length × breadth

Area = √2 - [(3π/4) - (π/4)]

Area = √2 - (π/2)

Area = (π/√2)

Therefore, the area is found to be (π/√2) units².

Let x represent the number of hours that Fin volunteers. Which is the equation that would answer this question?
x+ 2x +1.5 = 12
x+x+x+1.5 = 12
x+ 2(x+1.5) = 12
x+ (2x +1.5) = 12

Answers

The equation that would answer this question is x + (2x + 1.5) = 12. where x is the number of hours that Fin volunteers, and 2x + 1.5 represents the number of hours that each of his friends volunteers.

How to find the equation?

In this scenario, you can set up an equation that represents the total amount of time Fin and his friends volunteer. Let 'x' be the number of Finn's volunteer hours. His friends volunteer 1.5 hours more than Finn, so the number of hours each friend volunteers can be represented by x + 1.5. The total number of hours that all three friends volunteered can be expressed as:

x + (x + 1.5) + (x + 1.5) = 12

Expansion of the 2nd and 3rd terms:

x + x + 1.5 + x + 1.5 = 12

Combining the same terms:

3x + 4.5 = 12

Subtract 4.5 from both sides:

3x = 7.5

Divide both sides by 3:

x = 2.5

So Fin volunteers his 2.5 hours.

Answer:To show that Lorenz curves are always concave up on the interval [0, 1], we can use the definition of a Lorenz curve, which is L(x) = xp. Taking the second derivative of L(x) with respect to x gives us L''(x) = p. Since p is always greater than 0, L''(x) is always greater than 0. This means that L(x) is always concave up on the interval [0, 1].

Table of Lorenz values for p = 1.2, 1.5, 2.1, 2.5, 3, and 5:

a. The value of p that corresponds to the most equitable distribution of wealth is 1, as this would mean that the proportion of wealth held by each portion of the population is equal.

b. The value of p that corresponds to the least equitable distribution of wealth is 5, as this would mean that a small portion of the population holds a large proportion of the wealth.

The Gini Index is a measure of income inequality, where a value of 0 represents perfect equality (everyone has the same income) and a value of 1 represents perfect inequality (one person has all the income). The Gini Index is calculated as the ratio of the area between the Lorenz curve and the line of equality to the total area beneath the line of equality.

To find A and B for the Gini index we can use the following integral:

A = ∫(L(x) - x) dx from 0 to 1

B = ∫(x - L(x)) dx from 0 to 1

We can then solve the integral for each specific function of L(x) = xp to find the specific value of A and B.

Answers

The fastest speed of the bird of species A is 185 mph and the fastest speed of the bird of species B is 37 mph

What is an equation?

An equation is an expression showing the relationship between numbers and variables.

Let a represent the top speed of bird A and b represent the top speed of bird B.

A bird of species ​ A, when diving, can travel 5 times as fast as a bird of species B top speed, hence:

a = 5b

a - 5b = 0     (1)

If the total speeds for these two birds is 222 miles per hour, hence:

a + b = 222    (2)

To solve by elimination method, subtract equation 2 from 1, hence:

-6b = -222

Dividing by -6:

b = 37

Answers

The smaller number is 15 and the larger number is 36.

Let x and y be the smaller and larger numbers, respectively.

From the given information, we know:

y = x + 21 (because the larger number is 21 more than the smaller number)

x + y = 51 (because the sum of the two numbers is 51)

We can substitute the first equation into the second equation to find the value of x:

x + (x + 21) = 51

x + x + 21 = 51

2x = 30

x = 15

Now that we know the value of x, we can use the first equation to find the value of y:

y = x + 21

y = 15 + 21

y = 36

Answers

The amount  of marginal product of the 13th worker is 10 units of output, which is the difference between the quantity of output when L = 12 (122) and when L = 13 (132).

The marginal product of the 13th worker can be calculated as follows:

Marginal product = Quantity of output for L = 13 - Quantity of output for L = 12

Marginal product = 132 - 122

Marginal product = 10 units of output

The marginal product of the 13th worker is the additional output created by hiring one additional worker. This is calculated by taking the difference between the quantity of output when the number of workers is 12 and when it is 13. In this case, the quantity of output when L = 12 is 122, and when L = 13 it is 132, so the marginal product is 10 units of output. This calculation shows that the 13th worker is adding 10 units of output to the firm's total production. This is an important concept in production economics, as it helps firms determine the optimal number of workers to hire in order to maximize their output and profits.

decide whether each proposed multiplication or division of measurements is possible. if it is possible, write the result in the last column of the table.

Answers

1. The unit g/cm³ is valid. So, division of measurements is possible.

2. The unit mm is valid. So, division of measurements is possible.

3. The unit L² is not valid. So, multiplication of measurements is not possible.

What are measurement units?

The group of units used to quantify different physical quantities collectively known as the units of measurement. Since ancient times, we have measured these things using many units, including length, mass, volume, current, and temperature.

1. 63g/7cm³ = 9 g/cm³

The density of a substance indicates how dense it is in a given area. Mass per unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a particular physical characteristic of a specific thing.

The unit g/cm³ is a unit for measuring density.

Therefore, the division of measurements is possible.

2. The m or mm must be converted so that the units are the same.  

1 m = 1000 mm.

Convert the meters to mm:  

0.080 m = 80 mm.

480 mm²/80 mm = 6 mm

The word "area" refers to a free space. A shape's length and width are used to compute its area. Unidimensional length is expressed in terms of feet (ft), yards (yd), inches (in), etc.

The mm² is a unit for measuring area.

The m is a unit for measuring length or width.

Therefore, the division of measurements is possible.

3.  (4.5 dL) × (0.70 L)

Liquid volume is a term used to describe how much 3-D space a given amount of liquid takes up.

Volume of a liquid is measured in litres (L).

Squaring Litres doesn't make any sense.

Therefore, the multiplication of measurements is not possible.

it is possible to have a function with an infinite number of critical points. also, it is possible to have a function where every point is a critical point. g

Answers

A function with an infinite number of critical points can be expressed as a continuous function with a derivative that is equal to zero at every point in its domain.

For example, the function f(x) = 0 has an infinite number of critical points since its derivative f'(x) = 0 for every x in its domain. Alternatively, a function that has every point as a critical point can be expressed as a function with a derivative that is always equal to zero. For example, the constant function f(x) = c has a derivative f'(x) = 0 for every x in its domain, and thus every point in its domain is a critical point.

In addition, an example of a function with every point as a critical point is the constant function, f(x) = c, where c is a constant. The derivative of this function is f'(x) = 0, which means that the derivative is zero for all values of x. Therefore, every point of the constant function is a critical point.

Joseph has a bag filled with 2 red, 4 green, 15 yellow, and 9 purple marbles. Determine P(not purple) when choosing one marble from the bag.

A. 70%
B. 50%
C. 30%
D. 20%

Answers

The probability of randomly selecting a marble that is not purple is 70%, so the correct option is A.

How to find the probability?

We know that there are:

2 red marbles4 green marbles15 yellow marbles9 purple marbles

For a total number of 2 + 4 + 15 + 9 = 30

There are a total of 30 marbles on the bag, the probability of randomly selecting a marble that is not purple, is equal to the quotient between the number of marbles that are not purple and the total number of marbles.

21 marbles are not purple, then the probability is:

P = (21/30)*100%

P = 0.7*100%

P = 70%

The correct option is a.
