When firing a handgun , you should hold the handgun (d) at arm's length , from the body .

When firing a handgun, it is recommended to hold it at arm's length, from your body. This allows for proper control and aim of the firearm, as well as providing a buffer between you and the potential dangers of the discharge.

Holding the handgun too close to your body can also interfere with accuracy and control, as your arms may obstruct the movement of the gun. It's important to follow manufacturer guidelines and seek proper training and follow all safety procedures when handling handgun to ensure responsible and safe use.

The intensity of the light after it has passed through the second filter is zero.

The intensity of unpolarized light passing through a polarizing filter with an axis making an angle θ with the polarization direction is given by I = I0cos²θ.

In this case, the first filter has an axis making an angle of 40.0o with the vertical.

Therefore, the intensity of light passing through the first filter is I = I0cos²40.0o.

The second filter has a horizontal axis, which means it is perpendicular to the polarization direction of the light passing through it.

Therefore, the intensity of light passing through the second filter is given by I = I1cos²90o, where I1 is the intensity of light passing through the first filter.

Putting these equations together, we get:
I = I0cos²40.0o × cos²90o
I = I0cos²40.0o × 0
I = 0

Therefore, the intensity of light passing through the second filter is zero.

This is because the polarization direction of the light passing through the first filter is perpendicular to the axis of the second filter, which means all the light is blocked by the second filter.

In conclusion, the intensity of the light after it has passed through the second filter is zero.

The probability of getting (i) a king of red suit = 1 / 26 (ii) a face card = 3 / 13 (iii) a red face card = 3 / 26 (iv) a queen of black suit = 1 / 26 (v) a jack of hearts = 1 / 52 (vi) a spade = 1 / 4

Given, Total number of cards in a deck = 52 cards

(i) Probability of getting a king of red suit - A deck contains two red kings, one each in hearts and diamonds.

Therefore, P(getting a king of red suit) = (Number of kings of red suit) / (Total number of cards in the deck)

= 2 / 52= 1 / 26

(ii) Probability of getting a face card - A deck contains 12 face cards (4 Jacks, 4 Queens and 4 Kings)

Therefore, P(getting a face card) = (Number of face cards) / (Total number of cards in the deck)

= 12 / 52= 3 / 13

(iii) Probability of getting a red face card - A deck contains 6 red face cards (2 Jacks, 2 Queens and 2 Kings)

Therefore, P(getting a red face card) = (Number of red face cards) / (Total number of cards in the deck)

= 6 / 52= 3 / 26

(iv) Probability of getting a queen of black suit - A deck contains two black queens, one each in clubs and spades.

Therefore, P(getting a queen of black suit) = (Number of queens of black suit) / (Total number of cards in the deck)= 2 / 52= 1 / 26

(v) Probability of getting a jack of hearts - A deck contains only one jack of hearts

Therefore, P(getting a jack of hearts) = (Number of jacks of hearts) / (Total number of cards in the deck)= 1 / 52

(vi) Probability of getting a spade - A deck contains 13 spades

Therefore, P(getting a spade) = (Number of spades) / (Total number of cards in the deck)

The given data in the problem is that a key delivers 32 liters of water in 5 minutes. We are required to calculate how much time it will take to fill 288 liters of water.So, let's proceed with the solution,Step 1: We need to find out how many liters of water is filled in one minute. We can use the unitary method to solve the problem. We know that 32 liters of water is filled in 5 minutes. Hence, in one minute, the amount of water filled would be32/5 = 6.4 litersStep 2: Now, we need to find the time required to fill 288 liters of water. Again, we can use the unitary method. We have found out that the amount of water filled in one minute is 6.4 liters. Therefore, the time required to fill 288 liters of water would be 288/6.4 = 45 minutes.Therefore, the time taken by the key to fill 288 liters of water is 45 minutes.

The tangent function is defined as the ratio of the sine function to the cosine function, and it is periodic with a period of pi. It has vertical asymptotes at odd multiples of pi/2.
The tangent function can be represented by the following equation:
y = tan(x)
Where x is the angle measured in radians.
If we want to shift the graph of the tangent function by a certain amount, n, in the horizontal direction, we can use the following equation:
y = tan(x + n(pi))
Where n is an integer.
For example, if n = 2, then the graph of the tangent function would be shifted 2pi units to the left, and the equation would be:
y = tan(x - 2pi)
If n = 3, then the graph of the tangent function would be shifted 3pi units to the left, and the equation would be:
y = tan(x - 3pi)

If we shift the origin without changing the direction and point P(x, y) is changed to P(X, Y) then the new coordinates will be x = X + h and y = Y + k.

Shifting of origin is the phenomenon of changing the coordinates of the origin which is generally (0, 0) to another point which has coordinated (h, k). This phenomenon is usually carried out graphically. This is done when there is difficulty to solve the problems in coordinate geometry when we take the origin at (0, 0).

If we shift the origin which is at P(x, y) to another point (h, k) then the coordinates of new point P(X, Y) will be

x = X + h and y = Y + k

If h is positive, then coordinates will be x = X + h and if h is negative then coordinates will be x = X - h. If k is positive, then coordinates will be y = Y + k and if k is negative then coordinates will be y = Y - k.

We need μ - 0.5σ^2 = 0, or equivalently:

μ = 0.5σ^2

In Example 5.4, we have the following:

The stock price at time t, St, is modeled as a geometric Brownian motion with constant drift and volatility, such that dSt = μSt dt + σSt dWt, where μ is the drift rate, σ is the volatility, and dWt is a Wiener process increment.

Taking the natural logarithm of both sides, we get d ln(St) = (μ - 0.5σ^2)dt + σdWt.

Letting Xt = ln(St), we have dXt = (μ - 0.5σ^2)dt + σdWt.

From the problem statement, we have that Xi = ei, where ei ~ N(0,1) for i = 1, 2, ..., n, where n is the number of time steps.

We want to find values of μ and σ such that Mn = exp(1/n Σi=1^n Xi) = exp(1/n Σi=1^n ei) = exp(1/n En) is a martingale, where En is the average of the N(0,1) random variables.

Using the fact that exp(a+b) = exp(a)exp(b), we have:

Mn+1 = exp(1/(n+1) Σi=1^(n+1) Xi) = exp(1/(n+1) Σi=1^n Xi)exp(Xn+1)

For Mn+1 to be a martingale, we need:

E[Mn+1 | Fn] = Mn

where Fn is the filtration up to time n. Since Xi are independent and identically distributed, we have:

E[Mn+1 | Fn] = E[exp(1/(n+1) En+1 + 1/(n+1) Σi=1^n ei) | Fn] = Mn exp(1/(n+1) E[en+1])

where en+1 ~ N(0,1). Note that E[en+1] = 0 and Var[en+1] = 1.

Thus, we need:

Mn exp(1/(n+1) E[en+1]) = Mn

or equivalently:

exp(1/(n+1) E[en+1]) = 1

Taking the logarithm of both sides, we get:

1/(n+1) E[en+1] = 0

or:

E[en+1] = 0

Therefore, we need μ - 0.5σ^2 = 0, or equivalently:

μ = 0.5σ^2

This is the same condition as in Example 5.4, which ensures that the lognormal stock prices follow a martingale.

The values of the missing angles and sides after dilation are:

m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

Thus, by way of scale factor we can say that:

BC/B'C' = BD/B'D' = 36/18 = 2

B'D' = ¹/₂BD = ¹/₂ * 22 = 11

The median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution in statistics and probability theory. It could be considered "the intermediate" value for a set of data.

An ordered data set's median is its middle number. The mean is calculated as the product of all values divided by all possible values.

The entire distance traveled by the object in a specific amount of time is its average speed. A scalar quantity, average speed, exists. The magnitude serves as its representation, and it lacks direction.

The typical wind speeds for two nations have been provided to us.
