If 5 adult movie tickets cost $25, how much do 11 tickets cost?

The task is to find f '(0.4) for the function f(x) = ∫[0 to x] arcsin(t) dt. The possible answers are: 0.081, 0.412, 0.389, and 1.091. The closest value to 0.4115 is 0.412. Thus, the answer is 0.412.

To find f '(0.4), we need to differentiate the function f(x) with respect to x. Applying the Fundamental Theorem of Calculus, we have f '(x) = arcsin(x). Therefore, to find f '(0.4), we substitute x = 0.4 into the derivative expression: f '(0.4) = arcsin(0.4). Evaluating this trigonometric function, we find that arcsin(0.4) is approximately 0.4115. Among the given options, the closest value to 0.4115 is 0.412. Thus, the answer is 0.412.

According to the United Nations, the current world population as of 2021 is approximately 7.9 billion people. The units used to measure this estimate is in billions. I used the United Nations website to locate this information.

The world population has increased by approximately 800 million people over the last 10 years. I used the same United Nations website to locate this information. Looking at the table below, the population growth in the last ten years is significantly higher than the growth between 1950-1960. In the 1950s, the world population was around 2.5 billion, and it grew to around 3 billion by the end of the decade. In comparison, over the last ten years, the world population has grown from 6.9 billion to 7.9 billion. To compare the growth over different periods of time, I looked at the percentage change in population growth and calculated it for each decade. This allowed me to compare the growth rates between different periods of time.

There are several factors that influence population growth. These include birth rates, death rates, migration, and age structure. Birth rates and death rates are influenced by factors such as access to healthcare, education, and economic conditions. Migration can also have a significant impact on population growth, as it can either add to or subtract from a country's population. Age structure, or the proportion of the population in different age groups, can also affect population growth. For example, a country with a large proportion of young people may experience higher population growth than a country with an older population.

The two integers can be represented by variables, let's say 'x' and 'y'. the two integers are x = 8 and y = 19.

From the given information, we can establish two equations to form a linear system.

Equation 1: The sum of two integers is 27.

x + y = 27

Equation 2: The larger integer is 30 less than twice the smaller.

x = 2y - 30

To solve this system, we can use substitution or elimination method. Let's use the substitution method.

Substitute the value of x from Equation 2 into Equation 1:

2y - 30 + y = 27

Combine like terms:

3y - 30 = 27

Add 30 to both sides:

3y = 57

Divide both sides by 3:

y = 19

Now substitute the value of y back into Equation 1:

x + 19 = 27

Subtract 19 from both sides:

x = 8

Therefore, the two integers are x = 8 and y = 19.

Step-by-step explanation:

The solution triangle is attached below :

Since we have a right angled triangle, we can apply trigonometry to obtain the angle ladder makes with the ground;

Let the angle = θ

Tanθ = opposite / Adjacent

Tanθ = 50/30

θ = tan^-1(50/30)

θ = 59.036°

θ = 59.04°

The length of ladder can be obtained using Pythagoras :

Length of ladder is the hypotenus :

Hence,

Hypotenus = √(adjacent² + opposite²)

Hypotenus = √(50² + 30²)

Hypotenus = √(2500 + 900)

Hypotenus = 58.309

Length of ladder = 58.31 inches

Answer:

59°

58.3 inches

Step-by-step explanation:

Here is the full question :

A ladder is placed 30 inches from a wall. It touches the wall at a height of 50 inches from the ground. The angle made by the ladder with the ground is degrees, and the length of the ladder is inches.

Please check the attached image for a diagram explaining this question

The angle the ladder makes with the ground is labelled x in the diagram

To find the value of x given the opposite and adjacent lengths, use tan

tan⁻¹ (opposite / adjacent)

tan⁻¹  (50 / 30)

tan⁻¹ 1.667

= 59°

the length of the ladder can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

√(50² + 30²)

√(2500 + 900)

√3400

= 58.3 inches

Length of outer boundary =30m

So area of outer boundary =30×30

= 900m²

Length of inner boundary of path=30-1= 29m

Inner area =29×29 =841m²

So area of path is= outer area - inner area

=900- 841

= 59m²

The Mean Absolute Percentage Error (MAPE) for a four-month moving average method applied to the given patient data is 13.7196%.

To calculate the MAPE using a four-month moving average method, we need to find the average of the absolute percentage errors for each month's forecasted value compared to the actual value.

First, we calculate the four-month moving average for each month using the provided data:

Moving Average for Month 1 = (593 + 464 + 618 + 765) / 4 = 610

Moving Average for Month 2 = (464 + 618 + 765 + 553) / 4 = 600

Moving Average for Month 3 = (618 + 765 + 553 + 731) / 4 = 666.75

Moving Average for Month 4 = (765 + 553 + 731 + 647) / 4 = 674

Moving Average for Month 5 = (553 + 731 + 647) / 3 = 643.67

Moving Average for Month 6 = (731 + 647) / 2 = 689

Moving Average for Month 7 = 647

Next, we calculate the absolute percentage error for each month's forecasted value compared to the actual value:

APE for Month 1 = |(610 - 593) / 593| = 0.0287

APE for Month 2 = |(600 - 464) / 464| = 0.2927

APE for Month 3 = |(666.75 - 618) / 618| = 0.0789

APE for Month 4 = |(674 - 765) / 765| = 0.1183

APE for Month 5 = |(643.67 - 553) / 553| = 0.1630

APE for Month 6 = |(689 - 731) / 731| = 0.0575

APE for Month 7 = |(647 - 647) / 647| = 0

Finally, we find the average of the absolute percentage errors and multiply it by 100 to obtain the MAPE:

MAPE = (0.0287 + 0.2927 + 0.0789 + 0.1183 + 0.1630 + 0.0575 + 0) / 7 * 100 ≈ 13.7196%

Therefore, the value of MAPE (in percent) for the four-month moving average method applied to the given patient data is approximately 13.7196%.

the possible values of r are 1 + i and 1 - i.

(1) Consider the following ode

:(x²−1)y"(x)+3xy'(x)+3y=0

We check if x = 100 is an ordinary point. For that, we find the first two derivatives of the coefficient functions given by

p(x) = 3x/(x² - 1) and q(x) = 3/(x² - 1)².

p(x) = (3(x² - 1) + 3x.2x)/(x² - 1)² = 6x/(x² - 1)²p'(x)

= (6(x² - 1)² - 6x.2(x² - 1).2x)/(x² - 1)⁴

= 6(x⁴ - 2x² + 1)/(x² - 1)⁴

Clearly, both p(x) and p'(x) are analytic at x = 100. Thus, x = 100 is an ordinary point.

The given ode is of the form:

p(x)y''(x) + q(x)y'(x) + r(x)y(x) = 0where p(x) and q(x) are analytic at x = 100. Therefore, the radius of convergence of the power series solution around x = 100 is given by

R = min{|x - 100| : x is a singular point}

For the given ode, x = ±1 are singular points.

Therefore,

R = min{|100 - 1|, |100 - (-1)|} = 99(2) Consider the ode again:(x²−1)y"(x)+3xy'(x)+3y=0At x = 1, we have p(1) = 3/0 and q(1) = 3/4. Therefore, x = 1 is a regular singular point. Thus, the power series solution of the form

8y(x) = (x - 1)Σan(x − 1)^(r-n)

where a0 is nonzero and r is a root of the indicial equation:

r(r - 1) + 3r + 3 = 0

which simplifies tor² + 2r + 3 = 0

Using the quadratic formula, we have:

r = (-2 ± √4 - 4(3))/2 = -1 ± i

Therefore, the possible values of r are

-1 + i and -1 - i.(3)

Consider the ode again:(x²−1)y"(x)+3xy'(x)+3y=0At x = -1,

we have p(-1) = -3/4 and q(-1) = 3/0.

Therefore, x = -1 is a regular singular point.

Thus, the power series solution of the form

y(x) = (x + 1)Σan(x + 1)^n

where a0 is nonzero and r is a root of the indicial equation:

r(r + 1) - 3r + 3 = 0

which simplifies tor² - 2r + 3 = 0

Using the quadratic formula, we have:

r = (2 ± √4 - 4(3))/2 = 1 ± i

Therefore, the possible values of r are 1 + i and 1 - i.

Answer:

A. m(arc BC) = 16°

B. m(arc BAC) = 344°

Step-by-step explanation:

From the picture attached,

AB is the diameter of the circle.

Since, measure of an arc is always same as the central angle of arc.

Therefore, m(arc AC) = m(∠ADC) = 164°

m(arc AB) = 180°

m(arc BC) = 360° - m(arc AB) + m(arc AC)

                = 360° - (180° + 164°)

                = 360° - 344°

                = 16°

m(arc BAC) = m(arc AB) + m(arc AC)

                   = 180° + 164°

                   = 344°

Using Phythagoras Theorem:-

\( \sf \hookrightarrow \: {(AC)}^{2} = {(AB)}^{2} +{(BC)}^{2} \)

\( \sf \hookrightarrow \: {(x)}^{2} = {(11)}^{2} +{(15)}^{2} \)
