Which of the following is and isn't a function? ( There may be more than one answer ). Explain Clearly

The series has an alternating sign since every term is positive, and |(an + 1 / an)| is decreasing to 9/49. Therefore, we can use the Alternating Series Test to conclude that the series converges.

Using the Ratio Test:

lim n -> [infinity] |(9^(n+1) / ((n+1)+1)7^(2(n+1) + 1)) / (9^n / (n+1)7^(2n + 1))|

= lim n -> [infinity] |(9^(n+1) / 7^(2n+3)) * ((n+1)7^(2n+1) / (n+2)7^(2n+3))|

= lim n -> [infinity] |(9 / 49) * (n+1) / (n+2)|

= 9/49

Since the limit is less than 1, the series converges.

In Chapter 2 of Volume II of Frankenstein, Victor Frankenstein concludes by stating, "for the first time I felt what the duties of a creator towards his creature were" (85). Victor's remark implies that he has finally realized that he has a responsibility towards the creature he has created, and that he must accept the consequences of his creation.

Victor recognizes that as the creator of the creature, he is morally obliged to ensure that the creature is well-treated and cared for. Victor expresses remorse for creating the monster and for failing to take responsibility for his actions as the creature's creator. He finally acknowledges his role in the creature's life and feels a sense of obligation to be there for him as his creator.

Victor understands the importance of having a sense of responsibility and accountability as a creator towards his creation. This demonstrates the theme of the novel, which is the dangers of playing God and the consequences that come with taking on a task that is beyond one's capabilities.

The exact rectangular coordinates for the polar coordinates (-10, 135°) are (5\(\sqrt{2}\), -5\(\sqrt{2}\)).

To convert polar coordinates to rectangular coordinates, we can use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

Given the polar coordinates (-10, 135°), where r is the distance from the origin (radius) and θ is the angle in degrees, we can apply these formulas.

x = (-10) * cos(135°)

y = (-10) * sin(135°)

To evaluate the trigonometric functions, we'll use the corresponding values from the unit circle:

cos(135°) = -\(\sqrt{2}\)/2

sin(135°) = \(\sqrt{2}\)/2

Substituting these values into the formulas, we have:

x = (-10) * (-\(\sqrt{2}\)/2)

y = (-10) * (\(\sqrt{2}\)/2)

Simplifying, we get:

x = 5\(\sqrt{2}\)

y = -5\(\sqrt{2}\)

The probability of x taking on a value between 75 to 90 is 0.25.

Given that x is a continuous random variable uniformly distributed between 65 and 85.To find the probability that x lies between 75 and 90, we need to find the area under the curve between the values 75 and 85, and add to that the area under the curve between 85 and 90.

The curve represents a rectangular shape, the height of which is the maximum probability. So, the height is given by the formula height of the curve = 1/ (b-a) = 1/ (85-65) = 1/20.Area under the curve between 75 and 85 is = (85-75) * (1/20) = (10/20) = 0.5Area under the curve between 85 and 90 is = (90-85) * (1/20) = (5/20) = 0.25.

6,702 = 6 thousands and 7 hundreds and 0 tens and 2 ones

\(= 6 \times 1000 + 7 \times 100 + 0 \times 10 + 2 \times 1\)

\(= 6000 + 700 + 2\).

Above, we have written the number 6,702 in expanded form, or as a SUM of its different parts according to place value. The digit 6 in the number 6,702 actually has the value 6,000 and the digit 7 actually signifies the value 700. This is why our number system is also called a place value system, because the value of a digit (like 6 or 7 in our example) depends on its placement within the number. In other words, the digit 6 in 6702 does not mean six but six thousand, because the six is placed in the thousands' place. The place of a digit determines its value. I'll go for 66.04 that's the closest.

Step-by-step explanation:

As we know that the slope-intercept form of the equation is

\(y=mx+b\)

Now, comparing the given equations with the slope-intercept form

a) y = 4/5x + 3

Here:

m = 4/5

Therefore, the slope of the equation y = 4/5x + 3 is: m = 4/5

b) y = -x + 1

Here:

m = -1

Therefore, the slope of the equation y = -x + 1 is: m = -1

b) y = 2x

Here:

m = 2

y-intercept = b = 0       ∵ y = mx+b here b is the y-intercept

Therefore, the slope of the equation y = 2x is:

m = 2 and

y-intercept = b = 0

3. The current price of the common stock is $40.

4. The stock price considering the company quitting business after 25 years is $46.81.

5. The stock price assuming constant dividends is $26.67.

6. The stock price assuming constant dividends and the company quitting business after 25 years is $25.88.

3. The current price of the common stock can be calculated using the dividend discount model. The formula for the stock price is P = D / (r - g), where P is the stock price, D is the dividend, r is the required return, and g is the growth rate. In this case, the dividend is $4, the required return is 15% (0.15), and the growth rate is 5% (0.05). Plugging these values into the formula, we get P = 4 / (0.15 - 0.05) = $40.

4. If the company quits business after 25 years, we need to calculate the present value of the dividends for those 25 years and add it to the final liquidation value. The present value of the dividends can be calculated using the formula PV = D / (r - g) * (1 - (1 + g)^-n), where PV is the present value, D is the dividend, r is the required return, g is the growth rate, and n is the number of years. In this case, D = $4, r = 15% (0.15), g = 5% (0.05), and n = 25. Plugging these values into the formula, we get PV = 4 / (0.15 - 0.05) * (1 - (1 + 0.05)^-25) = $46.81. Adding the final liquidation value, which is the future value of the stock price after 25 years, we get $46.81 + $0 = $46.81.

5. Assuming constant dividends, the stock price can be calculated using the formula P = D / r, where P is the stock price, D is the dividend, and r is the required return. In this case, the dividend is $4 and the required return is 15% (0.15). Plugging these values into the formula, we get P = 4 / 0.15 = $26.67.

6. If the company quits business after 25 years and assuming constant dividends, we need to calculate the present value of the dividends for those 25 years and add it to the final liquidation value. The present value of the dividends can be calculated using the formula PV = D / r * (1 - (1 + r)^-n), where PV is the present value, D is the dividend, r is the required return, and n is the number of years. In this case, D = $4, r = 15% (0.15), and n = 25. Plugging these values into the formula, we get PV = 4 / 0.15 * (1 - (1 + 0.15)^-25) = $25.88. Adding the final liquidation value, which is the future value of the stock price after 25 years, we get $25.88 + $0 = $25.88.

The ordered pairs for the system of equations f(x) = x^2 -2x + 3 and f(x) = -2x + 12 are (3, 6) and (-3, 18)

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0)

f(x) = x^2 -2x +3 and f(x) = -2x + 12

which means

x^2 -2x +3  = -2x + 12

x^2 -2x +3  + 2x - 12 = 0

x^2 -9 = 0

by factorizing we have

(x-3)(x+3) = 0

x = 3 or -3

when x = 3

f(x) = -2x + 12

f(3) = -2(3) + 12 which is 6

when x = -3

f(-3) = -2(-3) + 12 which is 18

ordered pairs are (3, 6) and (-3, 18)

In conclusion, (3, 6) and (-3, 18) are the ordered pairs

If your friend picks a number larger than 5, the possible choices are 6, 7, 8, 9, and 10.  The correct answer is C) 1/8.

There are 5 numbers from 6 to 10. Out of these 5 numbers, only one of them is an 8. Therefore, the probability of picking an 8 if the number is larger than 5 is 1/5. However, the question specifically asks for the odds of picking an 8, which is different from probability.

Odds are calculated by dividing the probability of the event occurring by the probability of the event not occurring. The probability of not picking an 8 is 4/5, since there are 4 numbers from 6 to 10 that are not 8. So the odds of picking an 8 are 1/5 divided by 4/5, which simplifies to 1/8.

If your friend picks a number larger than 5, the possible choices are 6, 7, 8, 9, and 10. There is only one instance of the number 8 within these options. Therefore, the odds of your friend picking an 8 are: 1 (instance of 8) / 5 (total possible choices) = 1/5

Probability is the branch of mathematics concerned with measuring the likelihood or chance of events occurring. It is a way to quantify uncertainty and can be applied to a wide range of fields, including statistics, finance, and science.

The probability of an event is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. If the probability of an event is 0.5, for example, it means that the event has an equal chance of occurring or not occurring.

There are two main types of probability: theoretical and experimental. Theoretical probability is based on mathematical models and calculations, while experimental probability is based on observations and experiments.

A cardioid is a mathematical curve that is commonly studied in geometry and calculus. It is defined by the equation r = 1 + cos(θ), where r is the radial distance from the origin and θ is the polar angle. The cardioid has a distinctive heart-shaped form, and it is a smooth curve that can have tangent lines at certain points.

Horizontal Tangent Line:

A horizontal tangent line is a tangent line that is parallel to the x-axis. To find the points on the cardioid at which there is a horizontal tangent line, we need to find the points where the derivative of the curve is equal to zero in the x direction. The derivative of r = 1 + cos(θ) with respect to θ is -sin(θ), and the derivative of r with respect to x is cos(θ). Setting these two derivatives equal to zero, we have:

-sin(θ) = 0

cos(θ) = 0

The first equation has a solution when θ = n * π, where n is an integer. The second equation has solutions when θ = (2n + 1) * π/2, where n is an integer. When θ = n * π, the cardioid is at its maximum value, and when θ = (2n + 1) * π/2, the cardioid is at its minimum value. These points correspond to horizontal tangent lines on the cardioid.

Vertical Tangent Line:

A vertical tangent line is a tangent line that is perpendicular to the x-axis. To find the points on the cardioid at which there is a vertical tangent line, we need to find the points where the derivative of the curve is equal to zero in the y direction. The derivative of r with respect to y is sin(θ), and setting this derivative equal to zero, we have:

sin(θ) = 0

This equation has solutions when θ = (2n) * π/2, where n is an integer. These points correspond to vertical tangent lines on the cardioid.

Singular Point:

A singular point is a point on the curve at which the curve is not smooth and its tangent line is undefined. To find the singular points on the cardioid, we need to find the points where the second derivative of the curve is equal to zero. The second derivative of r = 1 + cos(θ) with respect to θ is -cos(θ), and setting this derivative equal to zero, we have:

-cos(θ) = 0

This equation has solutions when θ = n * π, where n is an integer. These points correspond to singular points on the cardioid.

In conclusion, the points on the cardioid at which there is a horizontal tangent line are given by θ = n * π and θ = (2n + 1) * π/2. The points at which there is a vertical tangent line are given by θ = (2n) * π/2. The singular points are given by θ = n * π. These points can be used to study the properties and behavior of the cardioid in more detail.

Answer:

Step-by-step explanation:

You want the measures of the angles marked m° and n° in the given figure.

The Claim, Evidence, Reasoning (CER) model tells us an explanation consists of:

Claim: The measure of m° is 63°.

Evidence: Angle m° is one of three angles in the figure that form a straight angle.

Reasoning: The measure of a straight angle is 180° (definition). The sum of the angles is equal to the whole (angle addition theorem).

  m° +90° +27° = 180°

  m° = 63° . . . . add -117° to both sides (addition property of equality)

Claim: The measure of n° is 28°.

Evidence: Angle n° is one of two angles in the figure that form a right angle.

Reasoning: The square corner signifies a right angle, whose measure is 90°. The angle addition theorem tells us that angle is the sum of the two angles into which it is divided:

  90° = 62° + n°

  28° = n° . . . . . . . add -62° to both sides (addition property of equality)

Step-by-step explanation:

Given

\(p = 60\%\)

\(n = 4\)

Required

The distribution of x

The above is an illustration of binomial theorem where:

\(P(x) = ^nC_x * p^x *(1 - p)^{n-x}\)

This gives:

\(P(x) = ^4C_x * (60\%)^x *(1 - 60\%)^{n-x}\)

Express percentage as decimal

\(P(x) = ^4C_x * (0.60)^x *(1 - 0.60)^{n-x}\)

\(P(x) = ^4C_x * (0.60)^x *(0.40)^{4-x}\)

When x = 0, we have:

\(P(x=0) = ^4C_0 * (0.60)^0 *(0.40)^{4-0}\)

\(P(x=0) = 1 * 1 *(0.40)^4\)

\(P(x=0) = 0.0256\)

When x = 1

\(P(x=1) = ^4C_1 * (0.60)^1 *(0.40)^{4-1}\)

\(P(x=1) = 4 * (0.60) *(0.40)^3\)

\(P(x=1) = 0.1536\)

When x = 2

\(P(x=2) = ^4C_2 * (0.60)^2 *(0.40)^{4-2}\)

\(P(x=2) = 6 * (0.60)^2 *(0.40)^2\)

\(P(x=2) = 0.3456\)

When x = 3

\(P(x=3) = ^4C_3 * (0.60)^3 *(0.40)^{4-3}\)

\(P(x=3) = 4 * (0.60)^3 *(0.40)\)

\(P(x=3) = 0.3456\)

When x = 4

\(P(x=4) = ^4C_4 * (0.60)^4 *(0.40)^{4-4}\)

\(P(x=4) = 1 * (0.60)^4 *(0.40)^0\)

\(P(x=4) = 0.1296\)

So, the probability distribution is:

\(\begin{array}{cccccc}x & {0} & {1} & {2} & {3} & {4} \ \\ P(x) & {0.0256} & {0.1536} & {0.3456} & {0.3456} & {0.1296} \ \end{array}\)
