A)the density of |x| is f(|x|) = 1/(1-0) = 1. B) the density of p|x| is f(p|x|) = 1/(p-0) = 1/p. C) the density of -ln|x| is f(-ln|x|) = 1/(∞-0) = 0. D) the density of sin(x) is f(sin(x)) = 1/(sin(1)-(-sin(1))).

(a) To find the density of |x|, we need to consider the range of values that |x| can take. Since x is uniformly distributed on the interval (-1, 1), the absolute value of x can take values between 0 and 1. The density function of |x| is given by f(|x|) = 1/(b-a), where a and b are the lower and upper bounds of the interval. In this case, a = 0 and b = 1. Therefore, the density of |x| is f(|x|) = 1/(1-0) = 1.

(b) To find the density of p|x|, we need to consider the range of values that p|x| can take. Since x is uniformly distributed on the interval (-1, 1), p|x| can take values between 0 and p. The density function of p|x| is given by f(p|x|) = 1/(b-a), where a and b are the lower and upper bounds of the interval. In this case, a = 0 and b = p. Therefore, the density of p|x| is f(p|x|) = 1/(p-0) = 1/p.

(c) To find the density of -ln|x|, we need to consider the range of values that -ln|x| can take. Since x is uniformly distributed on the interval (-1, 1), -ln|x| can take values between 0 and ∞. The density function of -ln|x| is given by f(-ln|x|) = 1/(b-a), where a and b are the lower and upper bounds of the interval. In this case, a  = 0 and b = ∞. Therefore, the density of -ln|x| is f(-ln|x|) = 1/(∞-0) = 0.

(d) To find the density of sin(x), we need to consider the range of values that sin(x) can take. Since x is uniformly distributed on the interval (-1, 1), sin(x) can take values between -sin(1) and sin(1). The density function of sin(x) is given by f(sin(x)) = 1/(b-a), where a and b are the lower and upper bounds of the interval. In this case, a = -sin(1) and b = sin(1). Therefore, the density of sin(x) is f(sin(x)) = 1/(sin(1)-(-sin(1))).

The value of the expression is 4.

The code :

int a[4] = {1, 2, 3, 4};

int *p = a;

what is *(p + 3)?

The variable a is an array of integers, and the variable p is a pointer to the first element of the array.

The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.

Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.

Therefore, the value of the expression is 4.

Here is a breakdown of the code:

int a[4] = {1, 2, 3, 4}: This line declares an array of integers called a and initializes it with the values 1, 2, 3, and 4.

int *p = a; This line declares a pointer to an integer called p and initializes it with the address of the first element of the array a.

what is *(p + 3)?: This line asks what the value of the expression *(p + 3) is.

The expression *(p + 3) is the value of the element of the array that is 3 elements after the element that p points to.

Since p points to the first element of the array, the expression *(p + 3) is the value of the fourth element of the array, which is 4.

Answer:  < -4/5,  3/5>

This is equivalent to writing < -0.8, 0.6 >

======================================================

Explanation:

Draw an xy grid and plot the point (-4,3) on it. Draw a segment from the origin to this point. Then draw a vertical line until reaching the x axis. See the diagram below.

We have a right triangle with legs of 4 and 3. The hypotenuse is \(\sqrt{4^2+3^2} = \sqrt{16+9} = \sqrt{25} = 5\) through use of the pythagorean theorem.

We have a 3-4-5 right triangle.

Therefore, the vector is 5 units long. This is the magnitude of the vector.

Divide each component by the magnitude so that the resulting vector is a unit vector pointing in this same direction.

Therefore, we go from < -4, 3 > to < -4/5,  3/5 >

This is equivalent to < -0.8, 0.6 > since -4/5 = -0.8 and 3/5 = 0.6

Side note: Unit vectors are useful in computer graphics.

therefore the value of x is x = 1.28

To find the area of a verandah 1 m wide constructed outside a room 5.5 m long and 4 m wide.

The area of the verandah is 45.5 m².

We need to find the area of the overall rectangular structure (room + verandah) and subtract the area of the room.

Area of the overall rectangular structure = (length + 2 × width) × (width + 1)

Area of the room = length × width

Area of the verandah = Area of the overall rectangular structure - Area of the room.

Given, Length of the room = 5.5 m

the Width of the room = 4 m

Width of the verandah = 1 m.

Area of the overall rectangular structure = (length + 2 × width) × (width + 1)

= (5.5 + 2 × 4) × (4 + 1)

= 13.5 × 5

= 67.5 m²

Area of the room = length × width

= 5.5 × 4

= 22 m²

Area of the verandah = Area of the overall rectangular structure - Area of the room

= 67.5 - 22

= 45.5 m²

Therefore, the area of the verandah is 45.5 m².

The modified Reynolds analogy, also known as the Chilton-Colburn analogy, is expressed mathematically as Nu = f * Re^m * Pr^n. It relates the convective heat transfer coefficient (h) to the skin friction coefficient (Cf) in fluid flow. This equation is widely used in heat transfer analysis and design applications involving forced convection.

The modified Reynolds analogy is a useful tool in heat transfer analysis, especially for situations involving forced convection. It provides a correlation between the heat transfer and fluid flow characteristics. The Nusselt number (Nu) represents the ratio of convective heat transfer to conductive heat transfer, while the Reynolds number (Re) characterizes the flow regime. The Prandtl number (Pr) relates the momentum diffusivity to the thermal diffusivity of the fluid.

The equation incorporates the friction factor (f) to account for the energy dissipation due to fluid flow. The values of the constants m and n depend on the flow conditions and geometry, and they are determined experimentally or by empirical correlations. The modified Reynolds analogy is widely used in engineering calculations and design of heat exchangers, cooling systems, and other applications involving heat transfer in fluid flow.

The correct statement that represents "Patricia is not a writer unless both Sam is an actor and Roberta is an actress" is option (d) (s & r) -> p.

The statement "Patricia is not a writer unless both Sam is an actor and Roberta is an actress" can be represented using logical connectives. Let's break down the statement:

- Patricia is not a writer: ~p (negation of Patricia being a writer)

- Sam is an actor: s

- Roberta is an actress: r

The statement "Patricia is not a writer unless both Sam is an actor and Roberta is an actress" implies that if both Sam is an actor (s) and Roberta is an actress (r), then Patricia is not a writer (~p).

This can be expressed using the implication operator (->), where (s & r) represents both Sam being an actor and Roberta being an actress, and ~p represents Patricia not being a writer. Therefore, the correct statement is (s & r) -> ~p, which is equivalent to (s & r) -> p after applying negation (~) to both sides.

The x-component of fluid acceleration in terms of x and y is 2.

To find the x-component of fluid acceleration (ax), we need to differentiate the x-component of velocity (u) with respect to time.

However, the given equations provide the expressions for u in terms of x and y, not time. Therefore, we need to differentiate u with respect to x and y instead.

Given: u = 2x + y^2

To find the x-component of fluid acceleration (ax), we differentiate u with respect to x while treating y as a constant:

ax = ∂u/∂x = ∂(2x + y^2)/∂x = 2

The probability of drawing a green ball first, a yellow ball second, and a red ball third is \(\frac{1}{21}\)

To calculate the probability of drawing a green ball first, a yellow ball second, and a red ball third, we need to consider the number of favorable outcomes (where the balls are drawn in the desired order) and the total number of possible outcomes.

The total number of balls in the urn is 4 (red) + 2 (green) + 3 (yellow) = 9 balls.

First, let's calculate the probability of drawing a green ball first.

There are 2 green balls out of the total 9 balls in the urn. So the probability of drawing a green ball first is \(\frac{2}{9}\).

After drawing a green ball, there are now 8 balls remaining in the urn (4 red and 3 yellow).

Therefore, the probability of drawing a yellow ball second is \(\frac{3}{8}\).

Finally, after drawing a green ball and a yellow ball, there are 7 balls left in the urn, with 4 of them being red.

Thus, the probability of drawing a red ball third is \(\frac{4}{7}\).

To calculate the overall probability, we multiply the probabilities of each individual event:

P(green first, yellow second, red third) = P(green first) * P(yellow second) * P(red third)

= \(\frac{2}{9} * \frac{3}{8}* \frac{4}{7}\)

Calculating this expression we finally obtain:

P(green first, yellow second, red third)

= \(\frac{24}{504}\)

= \(\frac{1}{21}\)

The area of the surface generated by rotating the parametric curve about the x-axis is π/8.

To find the area of the surface generated by rotating the parametric curve about the x-axis, we can use the formula for the surface area of revolution:

\(A = \int\limits^a_b {2\pi y} \sqrt{(\frac{dx}{d\theta})^2+ (\frac{dy}{d\theta})^2} \, dx\)

In this case, the given parametric equations are:

\(x = cos^3\theta\\\\y = sin^3\theta\)

Let's calculate the derivatives of x and y with respect to θ:

\(\frac{dx}{d\theta} = -3cos^2\theta sin\theta\\\\\frac{dy}{d\theta} = 3sin^2\theta cos\theta\\\)

Now we can substitute these values into the surface area formula:

\(A = \int_{0}^{\pi /2} {2\pi sin^3\theta} \sqrt{(-3cos^2\theta sin\theta)^2+ (3sin^2\theta cos\theta)^2} \, d\theta\)

Simplifying the expression inside the square root:

\(A = \int_{0}^{\pi /2} {2\pi sin^3\theta} \sqrt{9cos^4\theta sin^2\theta+ 9sin^4\theta cos^2\theta} \, d\theta\)

\(A = \int_{0}^{\pi /2} {2\pi sin^3\theta} \sqrt{9cos^2\theta sin^2\theta(cos^2\theta +sin^2\theta)} \, d\theta\)

\(A = \int_{0}^{\pi /2} {2\pi sin^3\theta} \sqrt{9cos^2\theta sin^2\theta} \, d\theta\)

\(A = \int_{0}^{\pi /2} {2\pi sin^3\theta} \quad 3cos^2\theta sin^2\theta \, d\theta\)

\(A = 6\pi \int_{0}^{\pi /2} {sin^4\theta} \quad cos^2\theta d\theta\)

Now, we can use a trigonometric identity to simplify the integral. The identity is:

\(Sin^2\theta = \frac{1-cos2\theta}{2}\)

Using this identity, we can rewrite the integral as:

\(A = 6\pi \int_{0}^{\pi /2} {(\frac{1-cos2\theta}{2})^2 } \quad cos^2\theta d\theta\)

Simplifying further:

\(A = 6\pi \int_{0}^{\pi /2} {(\frac{1+cos^22\theta-2cos2\theta}{4}) } \quad cos^2\theta d\theta\)

\(A = 3\pi /2\int_{0}^{\pi /2} {cos\theta-2cos2\theta cos\theta+\frac{1}{4} cos^3\theta} d\theta\)

Evaluating the limits of integration:

\(A = 3\pi /2[\frac{1}{2} sin\theta-\frac{1}{3} cos^3\theta+\frac{1}{12} cos^32\theta]^{\pi /2}_0\)
