When searching for the value 10 in the array [2, 3, 5, 6, 9, 13, 16, 19], a recursive binary search algorithm will return false since the element is not found in the array.
About Binary Search Algorithm
The binary search algorithm, applied on arrays are of recursive type. The broad strategy is to look at the middle item on the list. The procedure of the binary search algorithm is either terminated (key found), the left half of the list is searched recursively, or the right half of the list is searched recursively, depending on the value of the middle element.
The function carrying out the binary search algorithm in a code returns true if the desired element is found in the array, else returns false. Since the element 10 is not present in the given array: [2, 3, 5, 6, 9, 13, 16, 19], the binary search algorithm will return false.

Inferential statistics enables you to draw conclusions ("inferences") from descriptive statistics, which describes data (such as a chart or graph). Using inferential statistics, you can draw conclusions about a population using data from samples. Using inferential statistics, you can try to discover whether the sample data from a tiny sample of people can forecast whether the medication will be effective for everybody (i.e. the population). There are several techniques to accomplish this, including post-hoc (advanced) testing and generating a z-score, which shows where your data would fall in a normal distribution.

6. Redo Problem #3 assuming that dividends are constant and the company quits business after 25 years. (5)

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 value of the constant A can be obtained by using the normalization condition that the integral of the PDF function over the entire possible range of X must be equal to 1. So, we can write the following integral to solve for
A:(∫f(x) dx) from 0 to π/2=∫A sin(x) dx= A [-cos(x)] evaluated at π/2 and 0= -A(cos(π/2) - cos(0))= A (1 - 0) =1. Therefore, the value of the constant A is 1. b. The CDF of the given random variable X is given as follows:
F(x)=∫f(x)dx from 0 to x, for 0 < x < π/2=∫sin(x) dx from 0 to x= [-cos(x)] evaluated at x and 0= -cos(x) - (-cos(0))= 1 - cos(x) for 0 < x < π/2=1 for x ≥ π/2. So, the corresponding CDF is as follows:
F(x) = 1 - cos(x) for 0 < x < π/2F(x) = 1 for x ≥ π/2c. The expected value or mean of the given random variable X can be obtained using the following formula:
E(X) = ∫xf(x)dx from 0 to π/2=∫x sin(x) dx from 0 to π/2= [-x cos(x)] evaluated at π/2 and 0 - ∫-cos(x) dx from 0 to π/2= -0 + cos(0) - ([-cos(x)] evaluated at π/2 and 0)= 0 + 1 - (-1)= 2. So, the expected value of the given random variable X is 2.
d. The variance of the given random variable X can be obtained using the following formula:
Var(X) = E(X²) - [E(X)]²=∫x² f(x)dx from 0 to π/2 - [E(X)]²=∫x² sin(x)dx from 0 to π/2 - (2)²= [-x² cos(x)] evaluated at π/2 and 0 + ∫2x cos(x)dx from 0 to π/2 - 4= -0 + π²/4 - 4 + (2 sin(x) + 2x cos(x)) evaluated at π/2 and 0= π²/4 - 2 - 4 + 2 + 2π= π²/4 + 2π - 6. So, the variance of the given random variable X is π²/4 + 2π - 6
Hence, the answer is: a. The value of the constant A is 1.b. The corresponding CDF is : F(x) = 1 - cos(x) for 0 < x < π/2F(x) = 1 for x ≥ π/2c. The expected value or mean of the given random variable X is 2. d. The variance of the given random variable X is π²/4 + 2π - 6

Simple harmonic motion can be modelled with a sin function that has a period of 2pie. A maximum is located at x = pie/4. A minimum will be located at x = Зpie/4 5pie/4 pie 2pie
Simple harmonic motion can be represented by a sine function with a period of 2π. The maximum point occurs at x = π/4, and the minimum point will be located at x = 3π/4, 5π/4, and so on.
In simple harmonic motion, an object oscillates back and forth around an equilibrium position. The motion can be described by a sinusoidal function, typically a sine or cosine. For a sine function with a period of 2π, one complete cycle occurs over the interval from 0 to 2π.
Given that the maximum point of the motion is located at x = π/4, this represents the displacement of the object at the peak of its oscillation. To find the location of the minimum point, we need to determine when the displacement is at its lowest.
Since the period is 2π, the complete cycle repeats every 2π units. Therefore, the minimum point will occur at x = 3π/4, 5π/4, 7π/4, and so on, which are all equivalent to adding or subtracting 2π to the initial minimum point at x = π/4.
In summary, for simple harmonic motion modeled by a sine function with a period of 2π, the maximum point is located at x = π/4, and the minimum points will occur at x = 3π/4, 5π/4, 7π/4, and so on, which are all multiples of π/4 plus or minus 2π.

A regular hexagon has 6 lines of symmetry. These lines of symmetry divide the hexagon into 6 congruent parts.
The lines of symmetry of a regular hexagon are the lines that pass through the center of the hexagon and connect opposite vertices or connect the midpoints of opposite sides.Therefore, answer is b. 6
For 3rd Question:
If a trapezoid is located entirely in quadrant II, then all of its points will have a positive x-coordinate and a negative y-coordinate. When the trapezoid is reflected across the x-axis, the x-coordinates of all of its points will stay the same, but the y-coordinates will become positive. Therefore, the new trapezoid will be located entirely in quadrant I.
Quadrant II \(\tt ----------\longrightarrow\) Quadrant I
(x, -y) \(\tt ----------\longrightarrow\) (x, -y)
As you can see, the point (x, y) is located in quadrant II, but its reflection (x, -y) is located in quadrant I.
Therefore, the new trapezoid will be located in quadrant 1.
So the answer is b. 1.
\(\hrulefill\)
For 4th Question:
If all the coordinates of triangle ABC are from quadrant II to quadrant I, then the triangle must have been reflected across the x-axis.
This is because the x-coordinates of all the points in quadrant II are negative, but the x-coordinates of all the points in quadrant I are positive.
When a point is reflected across the x-axis, its x-coordinate stays the same, but its y-coordinate is negated.
Quadrant II \(\tt ----------\longrightarrow\) Quadrant I
(x, y)\(\tt ----------\longrightarrow\)(x, -y)
As you can see, the point (x, y) is located in quadrant II, but its reflection (x, -y) is located in quadrant I.
Therefore, the triangle must have been reflected across the x-axis.
So the answer is c. reflection.

the length of a rectangle is increasing at a rate of 5 cm/s and its width is increasing at a rate of 7 cm/s. when the length is 11 cm and the width is 9 cm, how fast is the area of the rectangle increasing (in cm2/s)?
The area of the rectangle is increasing at a rate of 122cm²/s if the length of the rectangle is 11 cm and the width is 9 cm.
The area of a rectangle can be described as the product of the length and width of that rectangle, therefore;
Area = L × W
Here L represents length and W represents the width
Now by differentiating using the product rule;
dA/dt = (dL/dt)(W) + (dW/dt)(L)
As the length is 11 cm and the width is 9 cm and the length is increasing at a rate of 5 cm/s and its width is increasing at a rate of 7 cm/s; substituting these values in the equation;
dA/dt = (5)(9) + (7)(11)
dA/dt = 45 + 77
dA/dt = 122
Hence, the area of the rectangle is increasing at the rate of 122cm²/s.
