This question is designed to be answered without a calculator. If f(x) = cos(In x) and f'(x) = g(x) - sin(In x), then g(x) = 01/11 1 2x 1 2x

Answers

The value of function g(x) is -1/2. Therefore, the correct answer is option C.

To solve this problem, we will use the basic rule of derivatives that states, if f(x)=g(x), then f'(x)=g'(x). Therefore, in this problem, we can rewrite the equation as f'(x)=g(x)- sin(ln x). We can then take the derivative of both sides:

f''(x)=g'(x)-cos(ln x).

Since f(x) is second-order differentiable and g(x) is first-order differentiable, we know that f'(x))=g'(x). Therefore, we can equate the two expressions to solve for G'(x) on the left side.

g'(x)=-1/2 cos(ln x).

Since g'(x) can be written as the derivative of g(x), we can then conclude that the answer to the problem is C) -1/2.

Therefore, the correct answer is option C.

If cosθ = - 7/9 and theta is in Quadrant III, find tanθ cotθ + csc θ.

Answers

The Pythagorean identity and the location of the angle θ, used to find the trigonometric ratios, indicates;

tan(θ)·cot(θ) + cscθ = (√(32) - 9)/√(32)

What is the Pythagorean identity?

The Pythagorean identity states that for all values of the angle θ, we get; cos²θ + sin²θ = 1

According to the Pythagorean identity, therefore, we get the following equation; sin²θ = 1 - cos²θ

sin²θ = 1 - (-7/9)² = 32/81

The angle θ is in Quadrant III, therefore, sinθ will be negative, which indicates;

sin(θ) = -√(32)/9

tan(θ) = (-√(32)/9)/(-7/9) = √(32)/7

cot(θ) = 1/tan(θ)

Therefore; cot(θ) = 1/(√(32)/7) = 7/√(32)

csc(θ) = 1/sin(θ)

Therefore; csc(θ) = 1/(-√(32)/9) = -9/√(32)

Therefore; tan(θ) × cot(θ)  + csc(θ) = 1 + (-9/√(32)) = (√(32) - 9)/√(32)

(a) To find the work needed to stretch the spring from 32 cm to 37 cm, we need to calculate the difference in potential energy. The potential energy stored in a spring is given by the equation:

Where PE is the potential energy, k is the spring constant, and x is the displacement from the natural length of the spring.

Given that the natural length of the spring is 24 cm and the work needed to stretch it from 24 cm to 42 cm is 2 J, we can find the spring constant:

2 J = (1/2)k(1764 - 576)

2 J = (1/2)k(1188)

Dividing both sides by (1/2)k:

4 J/(1/2)k = 1188

8 J/k = 1188

k = 1188/(8 J/k) = 148.5 J/cm

Now, we can calculate the work needed to stretch the spring from 32 cm to 37 cm:

Work = PE(37 cm) - PE(32 cm)

     = (1/2)(148.5 J/cm)(37^2 - 24^2) - (1/2)(148.5 J/cm)(32^2 - 24^2)

     ≈ 248.36 J

Therefore, the work needed to stretch the spring from 32 cm to 37 cm is approximately 248.36 J.

(b) To find how far beyond its natural length a force of 25 N will keep the spring stretched, we can use Hooke's Law:

F = kx

Where F is the force, k is the spring constant, and x is the displacement from the natural length.

Given that the spring constant is k = 148.5 J/cm, we can rearrange the equation to solve for x:

x = F/k

 = 25 N / 148.5 J/cm

 ≈ 0.1683 cm

Therefore, a force of 25 N will keep the spring stretched approximately 0.1683 cm beyond its natural length.

Answers

The volume of the parallelepiped with the given vertices is 648 cubic units.

To find the volume of a parallelepiped, we can use the formula V = |a · (b × c)|, where a, b, and c are the vectors representing the three adjacent edges of the parallelepiped.

Let's find the vectors representing the three adjacent edges:

a = (11 - 5, -7 - (-1), -9 - (-5)) = (6, -6, -4)

b = (12 - 5, 3 - (-1), -4 - (-5)) = (7, 4, 1)

c = (2 - 5, 5 - (-1), -11 - (-5)) = (-3, 6, -6)

Now, we can calculate the cross product of vectors b and c:

b × c = (4 * (-6) - 1 * 6, 7 * (-6) - 1 * (-3), 7 * 6 - 4 * (-3)) = (-30, -42, 54)

Finally, we can find the volume:

V = |a · (b × c)| = |(6, -6, -4) · (-30, -42, 54)| = |(-180) + (-252) + (-216)| = 648

Therefore, the volume of the parallelepiped is 648 cubic units.

Answers

I is a linear transformation.Let A be an invertible matrix and λ be an eigenvalue of A. Prove, using the definition of an eigenvalue, that is an eigenvalue of A-¹.

(4)The Definition of Eigenvalue: If A is a square matrix, a scalar λ is said to be an eigenvalue of A if there exists a non-zero vector x such that Ax = λx.Proof: Let's assume that λ is an eigenvalue of A, so by definition, there exists a non-zero vector x such that Ax = λx. Now let's look at the equation:

Ax = λx ⇒ A-¹Ax = A-¹λx ⇒ Ix = A-¹λx ⇒ λA-¹x = x,

which indicates that λ is an eigenvalue of A-¹. Moreover, since A is invertible, A-¹ exists. Hence the proof is completed.

If A is an invertible matrix that is diagonalisable, prove that A-¹ is diagonalisable.

(4)Proof: Suppose A is diagonalizable, so there exists a diagonal matrix D and an invertible matrix P such that

A = PDP-¹.

Now consider A-¹ = (PDP-¹)-¹= PD-¹P-¹. So A-¹ can be written in the form of a product of 3 invertible matrices, thus A-¹ is invertible. Now consider the equation A-¹x = λx. We can see that x≠0 since A-¹ is invertible. Now we can solve this equation:

A-¹x = λx ⇒ PD-¹P-¹x = λx ⇒ D-¹Px = λPx.

Now since D is diagonal and P is invertible, we can easily observe that D-¹ is diagonal. Hence we can conclude that A-¹ is diagonalizable.Let V and W be vector spaces and :

VW be a linear transformation. For v € V, prove that T(-v) = -T(v).

(3)Proof: We know that T is a linear transformation; therefore, we have T(-v) = T((-1)v) = -1T(v) = -T(v), since -1 is a scalar and it commutes with the linear transformation.Let T:

M22 → M22 be defined by T(A) = A+AT. Show that I is a linear transformation. (6)Proof: We need to prove that I is a linear transformation. That means:

For all A,B ∈ M22, and for all k ∈ R, T(kA+B) = kT(A)+T(B) and T(A+B) = T(A)+T(B). So, let's consider T(kA+B) first:

T(kA+B) = (kA+B)+(kA+B)T ⇒ T(kA+B) = kA+B+kAT+BT ⇒ T(kA+B) = k(A+AT)+(B+BT) ⇒ T(kA+B) = kT(A)+T(B). Now let's consider T(A+B):

T(A+B) = (A+B)+(A+B)T ⇒ T(A+B) = A+AT+BT+B+BT² ⇒ T(A+B) = T(A)+T(B). Hence I is a linear transformation.

A certain manufacturer estimates that the total weekly cost in producing q units is C(q) = 2000 + 2q – 0.00019² 0≤ ≤6000, dollars. (a) What is the actual cost incurred in producing the 1001st and the 2001st unit? (b) What is the marginal cost when q = 1000 and 2000?

Answers

(a) The actual cost incurred in producing the 1001st unit is 4000.799 dollars.

(b) The marginal cost when q = 1000 is dC/dq evaluated at q = 1000.

(a) To find the actual cost incurred in producing the 1001st and the 2001st unit, we can substitute the values of q into the cost function C(q) = 2000 + 2q - 0.00019q^2.

For the 1001st unit (q = 1001):

C(1001) = 2000 + 2(1001) - 0.00019(1001)^2

Calculating this expression will give us the actual cost incurred for producing the 1001st unit.

For the 2001st unit (q = 2001):

C(2001) = 2000 + 2(2001) - 0.00019(2001)^2

Similarly, calculating this expression will give us the actual cost incurred for producing the 2001st unit.

The actual cost incurred in producing the 1001st unit is 4000.799 dollars.

(b) The marginal cost represents the rate at which the cost changes with respect to the number of units produced. Mathematically, it is the derivative of the cost function C(q) with respect to q, i.e., dC/dq.

To find the marginal cost when q = 1000, we can differentiate the cost function C(q) with respect to q and evaluate it at q = 1000:

dC/dq = d/dq(2000 + 2q - 0.00019q^2)

Evaluate dC/dq at q = 1000 to find the marginal cost.

Similarly, to find the marginal cost when q = 2000, differentiate the cost function C(q) with respect to q and evaluate it at q = 2000.

Once we have the derivatives, we can substitute the corresponding values of q to find the marginal costs.

B) The marginal costs are:

C'(1000) = 1.62

C'(2000) = 1.24

How to find the actual cost and the marginal cost?

(a) To find the actual cost incurred in producing the 1001st and the 2001st unit, we need to substitute the values of q into the cost function C(q).

Given:

C(q) = 2000 + 2q - 0.00019*q²

For the 1001st unit (q = 1001):

C(1001) = 2000 + 2(1001) - 0.00019(1001)²

C(1001) = 3,811.6

For the 2001st unit (q = 2001):

C(2001) = 2000 + 2(2001) - 0.00019(2001)²

C(2001) = 5,241.2

(b) The marginal cost represents the rate of change of the total cost with respect to the number of units produced. To find the marginal cost at q = 1000 and 2000, we need to take the derivative of the cost function C(q) with respect to q.

Given:

C(q) = 2000 + 2q - 0.00019*q²

Taking the derivative:

C'(q) = dC(q)/dq = 2 - 20.00019q

Now, let's calculate the marginal cost when q = 1000:

C'(1000) = 2 - 20.000191000

Calculating:

C'(1000) = 2 - 20.000191000

C'(1000) = 2 - 0.38

C'(1000) = 1.62

The marginal cost when q = 1000 is $1.62.

Next, let's calculate the marginal cost when q = 2000:

C'(2000) = 2 - 20.000192000

Calculating:

C'(2000) = 2 - 20.000192000

C'(2000) = 2 - 0.76

C'(2000) = 1.24

Answers

The slope of the function V(x) = 19.4 + 2.3a represents the rate of change of the value of the investment per month.

In this situation, the slope of the function V(x) = 19.4 + 2.3a provides information about the rate at which the value of the investment changes with respect to time (months). The coefficient of 'a', which is 2.3, represents the slope of the function.

The slope of 2.3 indicates that for every one unit increase in 'a' (representing the number of months), the value of the investment increases by 2.3 thousand dollars. This means that the investment is growing at a constant rate of 2.3 thousand dollars per month.

It is important to note that the intercept term of 19.4 (thousand dollars) represents the initial value of the investment. Therefore, the function V(x) = 19.4 + 2.3a implies that the investment starts with a value of 19.4 thousand dollars and grows by 2.3 thousand dollars every month.

Answers

Function `f(x, y) = sin(y)e^(-y) + 8` is differentiable at the point `(0, π)`

To verify that the function `f(x, y) = sin(y)e^(-y) + 8` is differentiable at the point `(0, π)`, we will use the following theorem:

Suppose `f(x,y)` is a function of two variables with continuous partial derivatives in a region containing the point `(a,b)`. If `f(x,y)` is differentiable at `(a,b)`, then `f(x,y)` is continuous at `(a,b)`.Since `f(x, y) = sin(y)e^(-y) + 8` is a sum of two functions that are both differentiable, it follows that `f(x, y)` is differentiable.

We will show that both partial derivatives exist at `(0, π)`.fy(x, y) = cos(y)e^(-y) - sin(y)e^(-y) = e^(-y) cos(y) - e^(-y) sin(y) = e^(-y) (cos(y) - sin(y))fy(0, π) = e^(-π) (cos(π) - sin(π)) = -e^(-π) = -1 / e^πfz(x, y) = 0fz(0, π) = 0Since both partial derivatives exist at `(0, π)` and are continuous, it follows that `f(x, y)` is differentiable at `(0, π)`.

Summary:The partial derivatives `fy(x, y)` and `fz(x, y)` are `fy(x, y) = cos(y)e^(-y) - sin(y)e^(-y)` and `fz(x, y) = 0` respectively.Both partial derivatives are continuous at `(0, π)` which means `f(x, y)` is differentiable at `(0, π)`.

Answers

Answer:

x = 7

y = 13

Step-by-step explanation:

We are told that the numbers 1, 2, x, 11, y, 14 are in ascending order.

Therefore, x must be somewhere between 2 and 11, and y must be somewhere between 11 and 14.

[tex]\hrulefill[/tex]

Median

The median is the middle value of a data set when all the data values are placed in order of size.

There are 6 numbers in the data set. As this is an even number of data values, the median is the mean of the middle two data values, i.e. the mean of the numbers in 3rd and 4th position.

The two data values in 3rd and 4th position are x and 11.

Given the median is 9, we can set up the following equation and solve for x:

[tex]\begin{aligned}\dfrac{x+11}{2}&=9\\\\2 \cdot \dfrac{x+11}{2}&=2 \cdot 9\\\\ x+11&=18\\\\x+11-11&=18-11\\\\x&=7\end{aligned}[/tex]

Therefore, the value of x is 7.

[tex]\hrulefill[/tex]

Mean

The mean of a data set is the sum of the data values divided by the number of data values. Therefore, if the mean is 8, we can set up the following equation:

[tex]\dfrac{1+2+x+11+y+14}{6}=8[/tex]

Substitute the found value of x into the equation, and solve for y:

[tex]\begin{aligned}\dfrac{1+2+7+11+y+14}{6}&=8\\\\\dfrac{y+35}{6}&=8\\\\6 \cdot \dfrac{y+35}{6}&=6 \cdot 8\\\\y+35&=48\\\\y+35-35&=48-35\\\\y&=13\end{aligned}[/tex]

Therefore, the value of y is 13.

By using the cofactor expansion method along the first row, we calculated the determinant of the matrix A to be 39.

To find the determinant of the given matrix A using cofactor expansion, we'll expand along the first row. Let's denote the determinant as det(A).

Expanding along the first row, we have:

det(A) = 0 * C₁₁ - 1 * C₁₂ + 4 * C₁₃

Now let's calculate the cofactor for each entry in the first row:

C₁₁ = (-1)^(1+1) * det(A₁₁) = det(2 3; 8) = 2 * 8 - 3 * 0 = 16

C₁₂ = (-1)^(1+2) * det(A₁₂) = det(1 3; -3 8) = 1 * 8 - 3 * (-3) = 17

C₁₃ = (-1)^(1+3) * det(A₁₃) = det(1 2; -3 8) = 1 * 8 - 2 * (-3) = 14

Now substitute these values into the cofactor expansion:

det(A) = 0 * 16 - 1 * 17 + 4 * 14

Answers

That ~ is an equivalence relation and defined the operation [x] + [y] = [x+y] on R/~, showing that it is well-defined. Hence, ~ is an equivalence relation. Therefore, [a+b] = [x+y], and the operation + is well-defined.

(a) To prove that ~ is an equivalence relation, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any x∈R, we have x~x because x − x = 0 ≤ Z.

Symmetry: If xy, then x − y ≤ Z. Since the inequality is symmetric, y − x = -(x − y) ≥ -Z, which implies yx.

Transitivity: If xy and yz, then x − y ≤ Z and y − z ≤ Z. By adding these inequalities, we get x − z ≤ (x − y) + (y − z) ≤ Z + Z = 2Z, which implies x~z.

Hence, ~ is an equivalence relation.

Find the acute angle between the two curves at their points of intersection. 1- r= 1+ sinθ 2- r= 1 + 2 cosθ.

Answers

The acute angle between the two curves r = 1 + sinθ and r = 1 + 2cosθ at their points of intersection is α = arctan(3).

The two curves given by the equations r = 1 + sinθ and r = 1 + 2cosθ intersect at certain points.

To find the acute angle between the two curves at their points of intersection, we need to determine the angles of the tangents to the curves at those points.

First, let's find the points of intersection by equating the equations:

1 + sinθ = 1 + 2cosθ

sinθ = 2cosθ

Dividing both sides by cosθ:

tanθ = 2

This implies that the angles θ at the points of intersection satisfy the equation tanθ = 2.

One solution is θ = arctan(2).

Next, we find the slopes of the tangents to the curves at the points of intersection by taking the derivatives of the equations with respect to θ:

For the first curve, r = 1 + sinθ:

dr/dθ = cosθ

For the second curve, r = 1 + 2cosθ:

dr/dθ = -2sinθ

At θ = arctan(2), the slopes of the tangents are:

For the first curve, dr/dθ = cos(arctan(2)) = 1 / [tex]\sqrt(5)[/tex]

For the second curve, dr/dθ = -2sin(arctan(2)) = -2 / [tex]\sqrt(5)[/tex]

To find the acute angle between the two curves, we use the relationship between the slopes of two lines, m1 and m2:

tan(α) = |[tex](m_1 - m_2) / (1 + m_1m_2)[/tex]|

Substituting the values of the slopes, we get:

tan(α) = |((1 / [tex]\sqrt(5)[/tex]) - (-2 / [tex]\sqrt(5)[/tex])) / (1 + (1 / \[tex]\sqrt(5)[/tex])(-2 / [tex]\sqrt(5)[/tex]))|

Simplifying this expression, we find:

tan(α) = |-3 / (3 - 2)| = |-3 / 1| = 3

Therefore, the acute angle α between the two curves at their points of intersection is α = arctan(3).

In summary, the acute angle between the two curves at their points of intersection is α = arctan(3).

In summary, given a simple dataset with 30 points, the following steps were performed: (a) OLS estimation was used to calculate the coefficients β^0 and β^1 for the regression of Y on X.

(b) the predicted value of Y was calculated for each observation; (c) the residuals were calculated for each observation; (d) the Explained Sum of Squares (ESS), Total Sum of Squares (TSS), and Residual Sum of Squares (RSS) were calculated separately; (e) the coefficient of determination R^2 was calculated; (f) the predicted value of Y was determined when X equals the last digit of the CUNY ID plus one; and (g) the interpretation of β^0 and β^1 was provided.

In detail, to calculate the OLS estimates of coefficients β^0 and β^1, a regression model of Y on X was fitted using the given dataset. β^0 represents the intercept term, which indicates the value of Y when X is zero. β^1 represents the slope of the regression line, indicating the change in Y corresponding to a unit change in X.

The predicted value of Y for each observation was obtained by plugging the corresponding X value into the regression equation. The residuals were then calculated as the difference between the observed Y values and the predicted Y values. ESS represents the sum of squared differences between the predicted Y values and the mean of Y, indicating the variation explained by the regression model.

TSS represents the total sum of squared differences between the observed Y values and the mean of Y, representing the total variation in Y. RSS represents the sum of squared residuals, indicating the unexplained variation in Y by the regression model. R^2, also known as the coefficient of determination, was calculated as ESS divided by TSS, indicating the proportion of total variation in Y explained by the regression model. Finally, the predicted value of Y was determined when X equals the last digit of the CUNY ID plus one, allowing for an estimation of Y based on the given information.

Find general solution. y(4) - y" = 5e +3

Answers

The general solution of the given differential equation is y(t) = c₁e^t + c₂e^-t + 5/2 sin(t) + c₃cos(t) + c₄sin(t).

We are given the differential equation as:

y(4) - y" = 5e + 3

For solving this differential equation, we will use the method of undetermined coefficients. The characteristic equation is given by:

r⁴ - r² = 0

r²(r² - 1) = 0

r₁ = 1, r₂ = -1, r₃ = i, r₄ = -i

The complementary function (CF) will be:

yCF = c₁e^t + c₂e^-t + c₃cos(t) + c₄sin(t)

We can observe that the non-homogeneous part (NHP) of the given differential equation is NHP = 5e + 3.

We will assume the particular integral (PI) as:

yPI = Ae^t + Be^-t + Ccos(t) + Dsin(t)

Differentiating yPI with respect to t:

y'PI = Ae^t - Be^-t - Csin(t) + Dcos(t)

y"PI = Ae^t + Be^-t - Ccos(t) - Dsin(t)

y'''PI = Ae^t - Be^-t + Csin(t) - Dcos(t)

Substituting all the above values in the given differential equation, we get:

y(4)PI - y"PI = 5e + 3

(A + B)e^t + (A - B)e^-t + (C - D)cos(t) + (C + D)sin(t) - (A + B)e^t - (A - B)e^-t + Ccos(t) + Dsin(t) = 5e + 3

2Ccos(t) + 2Dsin(t) = 5e + 3

C = 0, D = 5/2

Substituting the values of C and D in the particular integral, we get:

yPI = Ae^t + Be^-t + 5/2 sin(t)

Hence, the general solution of the given differential equation is:

y(t) = yCF + yPI = c₁e^t + c₂e^-t + 5/2 sin(t) + c₃cos(t) + c₄sin(t)

long leg = x√3 = a√3

Given:

a=3√3

Find: b

solution:

b is long leg:

long leg = x√3 = a√3

b = a√3

b = 3√3 *√3

b= 3*3

b=9

Answer:

b = 9

Step-by-step explanation:

The given right triangle is a special type of triangle called a 30-60-90 triangle, as its interior angles are 30°, 60° and 90°.

The sides of a 30-60-90 triangle are in the ratio 1 : √3 : 2.

Therefore, the formula for the ratio of the sides is x : x√3 : 2x where:

x is the shortest side opposite the 30° angle.x√3 is the side opposite the 60° angle.2x is the longest side (hypotenuse) opposite the right angle.

From observation of the given diagram, we can see that side a is opposite the 30° angle. Given that a = 3√3, then x = 3√3.

Side b is opposite the 60° angle.

Therefore, to find the value of b, substitute x = 3√3 into the expression for the side opposite the 60° angle:

[tex]\begin{aligned}\implies b&=x\sqrt{3}\\&=3 \sqrt{3} \cdot \sqrt{3}\\&=3 \cdot 3\\&=9\end{aligned}[/tex]

Answers

The values of x, y, and z do not satisfy all three equations simultaneously.

To solve the triangular system using back-substitution, we start from the last equation and substitute the values into the previous equations.

Given equations:

2y + 3z = 10 ...(1)

2y - z = 3 ...(2)

3z = 15 ...(3)

From equation (3), we can solve for z:

3z = 15

z = 15/3

z = 5

Now, substitute the value of z into equation (2):

2y - z = 3

2y - 5 = 3

2y = 3 + 5

2y = 8

y = 8/2

y = 4

Finally, substitute the values of y and z into equation (1):

2y + 3z = 10

2(4) + 3(5) = 10

8 + 15 = 10

23 = 10

How much will each of those equal payments be if interest is 10% per year ? $12404.86 $1293.43 $12444.86 $1266.67 33

Answers

Therefore, each of the equal payments will be approximately $1,293.43.

To calculate the equal payments, we can use the concept of present value. We need to determine the present value of the total repayment amount, considering the interest rate of 10% per year.

The original repayment amounts were $2,000 and $1,800, which were due 60 days ago and 30 days ago, respectively. We need to calculate the present value of these two amounts.

Using the formula for present value, we have:

[tex]PV = FV / (1 + r)^n[/tex]

Where PV is the present value, FV is the future value, r is the interest rate, and n is the time period in years.

For the $2,000 repayment due 60 days ago, the present value is:

[tex]PV_1 = $2,000 / (1 + 0.1)^{(60/365)[/tex]

≈ $1,918.13

For the $1,800 repayment due 30 days ago, the present value is:

[tex]PV_2 = $1,800 / (1 + 0.1)^{(30/365)[/tex]

≈ $1,782.30

Now, we need to determine the equal payments that will be made today, 60 days from today, and 120 days from today.

Let's denote the equal payment amount as P.

The total present value of these equal payments should be equal to the sum of the present values of the original repayments:

[tex]PV_1 + PV_2 = P / (1 + 0.1)^{(60/365)} + P / (1 + 0.1)^{(120/365)}[/tex]

$1,918.13 + $1,782.30 =[tex]P / (1 + 0.1)^{(60/365)} + P / (1 + 0.1)^{(120/365)}[/tex]

$3,700.43 = P / 1.02274 + P / 1.04646

The center of gravity for the region R, bounded by the curves y = 2x, y = 9 - x², and the y-axis, can be found by evaluating the integrals for the x-coordinate, y-coordinate, and mass density.

To find the center of gravity, we need to compute the integrals for the x-coordinate, y-coordinate, and mass density. The x-coordinate is given by x = (1/A) ∬ xρ(x, y) dA, where ρ(x, y) represents the mass density. Similarly, the y-coordinate is given by y = (1/A) ∬ yρ(x, y) dA. In this case, the mass density is 6(x, y) = xy.

The integral for the x-coordinate can be written as x = (1/A) ∬ x(xy) dy dx, and the integral for the y-coordinate can be written as y = (1/A) ∬ y(xy) dy dx. We need to evaluate these integrals over the region R. By calculating the integrals and performing the necessary calculations, we can determine the values of x and y that represent the center of gravity.

A.B = [[0, 1, 4], [-1, 2, 0], [-1, 4, 8]] . B

Step 2: Subtract A.B from both sides of the equation to isolate X:

Let's solve for y at x = 2:x5 + 3y dx - x dy = 0Using exact differential equation,x5 dx + (- x)dy + 3y dx = 0This equation is an exact differential equation since the partial derivative of the term including y with respect to x and the term including x with respect to y are equal.d(x5)/dy = 0d(-x)/dx = -1.

Hence, integrating the above equation we get the general solution which can be expressed as,F(x5, y) = C, where C is an arbitrary constant.Now, putting x = 1, y = 2 in the above equation, we get:C = 5.1 + 3.2 = 11.

Therefore,F(x5, y) = 11Now, let's differentiate F(x5, y) = 11 with respect to x5 to get the value of y as required.df/dx5 = 0implies ∂F/∂x5 dx5 + ∂F/∂y dy = 0,

On substituting the values we have,∂F/∂x5 = 5x44∂F/∂y = 3ySo we have,5x44 dx5 + 3y dy = 0Substituting x5 = 25 and x = 2, we get,125/11 + 3y dy = 0.

Thus,3y dy = -125/11dy = -125/33Hence, y = -125/99Therefore, the value of y is -125/99 when x = 2.

The given differential equation is:x5 + 3y dx - x dy = 0We are supposed to find the value of y at x = 2.Using the concept of an exact differential equation, we have,x5 dx + (- x)dy + 3y dx = 0.

Now, for this differential equation to be an exact differential equation, the partial derivative of the term including y with respect to x and the term including x with respect to y must be equal.d(x5)/dy = 0d(-x)/dx = -1.

On integrating the above equation we get,F(x5, y) = C, where C is an arbitrary constant.Now, substituting the given values, x = 1 and y = 2 in the above equation we get,C = 5.1 + 3.2 = 11.

Thus, the general solution to the given differential equation can be given as,F(x5, y) = 11The value of y can be found by differentiating F(x5, y) with respect to x5.df/dx5 = 0.

implies ∂F/∂x5 dx5 + ∂F/∂y dy = 0On substituting the values we have,∂F/∂x5 = 5x44∂F/∂y = 3ySo we have,5x44 dx5 + 3y dy = 0.
Substituting x5 = 25 and x = 2, we get,125/11 + 3y dy = 0Thus,3y dy = -125/11dy = -125/33Hence, y = -125/99.

Answers

Graham initially agreed to make three payments of $18,000.00 each in 2 months, 7 months, and 10 months. Therefore, Graham should make the third payment in approximately 1 year and 1 month.

To find the time it will take to make the third payment of $10,000.00, we can use the formula for the future value of a series of payments:

FV = P * [(1 + r)^n - 1] / r

Where FV is the future value, P is the payment amount, r is the interest rate per period, and n is the number of periods.

In this case, the future value (FV) is $10,000.00, the payment amount (P) is $10,000.00, the interest rate (r) is 9% per year or 0.09 per month, and we need to solve for n.

Plugging in the values, we have:

$10,000.00 = $10,000.00 * [(1 + 0.09)^n - 1] / 0.09

Simplifying the equation, we get:

1 = (1.09)^n - 1

Solving for n, we find:

n = log(1.09)

Using a calculator, we find that log(1.09) is approximately 0.0862.

Since each period represents one month, the answer is approximately 0.0862 years, which is equivalent to 0.0862 * 12 = 1.0344 months.

Therefore, Graham should make the third payment in approximately 1 year and 1 month.

Answers

To solve the given initial value problem y" + 4y = -12sin(2x), y(0) = 1.8, y'(0) = 5.0, we can use the method of undetermined coefficients to find a particular solution and then combine it with the complementary solution.

Step 1: Find the complementary solution:

The complementary solution is the solution to the homogeneous equation y" + 4y = 0.

The characteristic equation is r² + 4 = 0, which has roots r = ±2i. Therefore, the complementary solution is y_c(x) = c₁cos(2x) + c₂sin(2x), where c₁ and c₂ are arbitrary constants.

Step 2: Find a particular solution:

We can guess a particular solution of the form y_p(x) = A sin(2x) + B cos(2x), where A and B are constants to be determined. Substituting this into the differential equation, we get:

-4A sin(2x) - 4B cos(2x) + 4(A sin(2x) + B cos(2x)) = -12sin(2x)

Simplifying, we have:

-4B cos(2x) + 4B cos(2x) = -12sin(2x)

0 = -12sin(2x)

This equation holds for all values of x, so there are no restrictions on A and B. We can set A = 0 and B = -3 to obtain a particular solution y_p(x) = -3cos(2x).

Step 3: Find the general solution:

The general solution is the sum of the complementary solution and the particular solution:

y(x) = y_c(x) + y_p(x) = c₁cos(2x) + c₂sin(2x) - 3cos(2x)

Simplifying further, we have:

y(x) = (c₁ - 3)cos(2x) + c₂sin(2x)

Step 4: Apply the initial conditions:

We are given y(0) = 1.8 and y'(0) = 5.0. Substituting these values into the general solution, we get:

1.8 = (c₁ - 3)cos(0) + c₂sin(0) = c₁ - 3

5.0 = -2(c₁ - 3)sin(0) + 2c₂cos(0) = -2(c₁ - 3)

Simplifying these equations, we have:

c₁ = 4.8

c₂ = -2.5

Therefore, the solution to the initial value problem is:

y(x) = 4.8cos(2x) - 2.5sin(2x)
