The correct question is given below:

Find the moment of inertia about the x-axis of a thin plate with density δ=5 bounded by the circle x2+y2=16. Then use your result to find Iy and Io.

the area of triangle $AMN$ is 8 square cm.

To find the area of triangle $AMN$, we need to determine the lengths of its base and height.

In square $ABCD$ with side length 4 cm, $N$ is the midpoint of side $BC$, so $BN = NC = \frac{1}{2} \cdot 4 = 2$ cm.

Similarly, $M$ is the midpoint of side $CD$, so $CM = MD = \frac{1}{2} \cdot 4 = 2$ cm.

Now, we can see that $AM$ is the height of triangle $AMN$ and has a length of 4 cm, as it is parallel to side $AD$ of the square.

$AN$ is the base of triangle $AMN$ and has a length of $BN + CM = 2 + 2 = 4$ cm.

Therefore, the area of triangle $AMN$ is given by:

$A_{AMN} = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 4 \times 4 = 8$ square cm.

The critical value for this test is -2.485 for the t-test for a left-tailed test with n=27 and α=0.01.

The critical value(s) for the t-test for a left-tailed test with n=27 and α=0.01 can be found using a t-distribution table.

Using the table with 26 degrees of freedom (n-1) and an alpha level of 0.01, we find the value of t to be -2.485. Since this is a left-tailed test, the critical value is the negative of the t-value. Therefore, the critical value for this test is -2.485.

The critical value is important in hypothesis testing as it helps us determine the cutoff point beyond which we reject the null hypothesis. In a left-tailed test, the critical value is the point on the t-distribution that has an area of alpha (0.01 in this case) to its left. If the calculated t-statistic falls beyond this critical value, we reject the null hypothesis.

The number of days in which Meena would be able to complete the work alone is 24 days.

In order to determine the number of days in which Meena would be able to complete the work alone, we would have to assign variables to the amount of time taken by Mala, Meena, and Vinay, and then translate the word problem into an algebraic equation as follows;

Note: Combined work rate = 1/x + 1/y + 1/z

Based on the information provided, we have the following equations that models the work rate by each person;

1/(x + y) = 10 ⇒ 1/10 = x + y    ........equation 1.

1/(y + z) = 12 ⇒ 1/12 = y + z    ........equation 2.

1/(x + z) = 15 ⇒ 1/15 = x + z    ........equation 3.

x + y + y + z + x + z = 1/10 + 1/12 + 1/15

2(x + y + z) = 15/60

2(x + y + z) = 1/4

x + y + z = 1/8

From equation 2, we have:

x + (y + z) = 1/8

x + 1/12 = 1/8

x = 1/8 - 1/12

x = 1/24

x = 24 days.

Yes, each vector in R4 can be written as a linear combination of the columns of matrix A.

To explain this, first, we must convert matrix A into its reduced row echelon form. This is done by performing row operations so that the leading (i.e. leftmost non-zero) entry in each row is a 1.

By doing this we can see that the columns of the matrix A form a basis for R4, which means that any vector in R4 can be written as a linear combination of the columns of A.

To be more specific, we can show that the columns of A span R4 by showing that the columns are linearly independent. To do this, we solve the equation Ax = 0, where x is the vector of unknowns. We can see that the only solution to this equation is x = 0, which implies that the columns of A are linearly independent and therefore span R4.

This means that any vector in R4 can be written as a linear combination of the columns of A. In other words, any vector in R4 can be expressed as a linear combination of the columns of A, which means that the columns of A span R4.

1. The solution to the first differential equation is given by e^2yx - ysin(xy) + y^2 + C = 0, where C is an arbitrary constant.

2. The general solution to the second differential equation is x(3x - y^2) = C, where C is a positive constant.

To solve the first-order differential equations, let's solve them one by one:

1. (e^2y - ycos(xy))dx + (2xe^2y - xcos(xy) + 2y)dy = 0

We notice that the given equation is not in standard form, so let's rearrange it:

(e^2y - ycos(xy))dx + (2xe^2y - xcos(xy))dy + 2ydy = 0

Comparing this with the standard form: P(x, y)dx + Q(x, y)dy = 0, we have:

P(x, y) = e^2y - ycos(xy)

Q(x, y) = 2xe^2y - xcos(xy) + 2y

To check if this equation is exact, we can compute the partial derivatives:

∂P/∂y = 2e^2y - xcos(xy) - sin(xy)

∂Q/∂x = 2e^2y - xcos(xy) - sin(xy)

Since ∂P/∂y = ∂Q/∂x, the equation is exact.

Now, we need to find a function f(x, y) such that ∂f/∂x = P(x, y) and ∂f/∂y = Q(x, y).

Integrating P(x, y) with respect to x, treating y as a constant:

f(x, y) = ∫(e^2y - ycos(xy))dx = e^2yx - y∫cos(xy)dx = e^2yx - ysin(xy) + g(y)

Here, g(y) is an arbitrary function of y since we treated it as a constant while integrating with respect to x.

Now, differentiate f(x, y) with respect to y to find Q(x, y):

∂f/∂y = e^2x - xcos(xy) + g'(y) = Q(x, y)

Comparing the coefficients of Q(x, y), we have:

g'(y) = 2y

Integrating g'(y) with respect to y, we get:

g(y) = y^2 + C

Therefore, f(x, y) = e^2yx - ysin(xy) + y^2 + C.

The general solution to the given differential equation is:

e^2yx - ysin(xy) + y^2 + C = 0, where C is an arbitrary constant.

2. x(yy' - 3) + y^2 = 0

Let's rearrange the equation:

xyy' + y^2 - 3x = 0

To solve this equation, we'll use the substitution u = y^2, which gives du/dx = 2yy'.

Substituting these values in the equation, we have:

x(du/dx) + u - 3x = 0

Now, let's rearrange the equation:

x du/dx = 3x - u

Dividing both sides by x(3x - u), we get:

du/(3x - u) = dx/x

To integrate both sides, we use the substitution v = 3x - u, which gives dv/dx = -du/dx.

Substituting these values, we have:

-dv/v = dx/x

Integrating both sides:

-ln|v| = ln|x| + c₁

Simplifying:

ln|v| = -ln|x| + c₁

ln|x| + ln|v| = c₁

ln

|xv| = c₁

Now, substitute back v = 3x - u:

ln|x(3x - u)| = c₁

Since v = 3x - u and u = y^2, we have:

ln|x(3x - y^2)| = c₁

Taking the exponential of both sides:

x(3x - y^2) = e^(c₁)

x(3x - y^2) = C, where C = e^(c₁) is a positive constant.

This is the general solution to the given differential equation.

The dimensions of the rhombus are given below.

Since H is the center of the rhombus, all sides are equal in length.

Let x be the length of each side. Then, we can use the Pythagorean theorem to solve for x:

DE = (EF/2)^2 + (DF/2)^2

DE² = (13/2)^2 + (18/2)^2

DE² = 169/4 + 324/4

DE² = 123.25

DE = sqrt(493)/2

Since DEFG is a rhombus, all sides are equal in length. Thus, we have:

EF = FG = 13

FG = GH = DE = 11.10

GH = HE = EF = 13

The expected value of the perimeter of a rectangle with side lengths X and Y+1 (where X is a geometric random variable with parameter p=.25 and Y is a Poisson random variable with parameter λ=4) is 18 and that the expected value of its area is 20.

To find the expected value of the perimeter of the rectangle, we need to first find the expected values of X and Y.

The expected value of a geometric random variable with parameter p is given by E(X) = 1/p. Therefore, in this case, E(X) = 1/p = 1/.25 = 4.

The expected value of a Poisson random variable with parameter λ is also λ. Therefore, in this case, E(Y) = λ = 4.

Since X and Y are independent, the expected value of the product XY is simply the product of their individual expected values. Therefore, E(XY) = E(X)E(Y) = 4*4 = 16.

Now, we can use these expected values to find the expected value of the perimeter of the rectangle. The perimeter is given by P = 2(X + Y + 1). Therefore,

E(P) = 2(E(X) + E(Y) + 1)

= 2(4 + 4 + 1)

= 18

So the expected value of the perimeter of the rectangle is 18.

To find the expected value of the area of the rectangle, we simply multiply the expected values of X and Y+1. Therefore,

E(Area) = E(X(Y+1))

= E(XY + X)

= E(XY) + E(X)

= 16 + 4

= 20

So the expected value of the area of the rectangle is 20.

a) The range is 14.

b) The sample variance is 20.78.

c) The sample standard deviation is 4.56.

a) Range

The range of a given set of data values is the difference between the maximum and minimum values in the set. In this case, the maximum value is 15 and the minimum value is 1. So, the range is:

Range = maximum value - minimum value

Range = 15 - 1

Range = 14

b) Sample variance

To calculate the sample variance, follow these steps:

1. Calculate the sample mean (X). To do this, add up all of the data values and divide by the total number of values:

n = 9

∑x = 7 + 4 + 6 + 12 + 8 + 15 + 1 + 9 + 13 = 75

X = ∑x/n = 75/9 = 8.33

2. Subtract the sample mean from each data value, square the result, and add up all of the squares:

(7 - 8.33)² + (4 - 8.33)² + (6 - 8.33)² + (12 - 8.33)² + (8 - 8.33)² + (15 - 8.33)² + (1 - 8.33)² + (9 - 8.33)² + (13 - 8.33)² = 166.23

3. Divide the sum of squares by one less than the total number of values to get the sample variance:

s² = ∑(x - X)²/(n - 1) = 166.23/8 = 20.78

Therefore, the sample variance is 20.78 (rounded to two decimal places).

c) Sample standard deviation

To calculate the sample standard deviation, take the square root of the sample variance:

s = √s² = √20.78 = 4.56

Therefore, the sample standard deviation is 4.56 (rounded to two decimal places).
