Linear equations are equations that have constant average rates of change, slope or gradient

A system of linear equations is a collection of at least two linear equations.

In this case, we have

Nancy

Initial = 400

Rate = 10

So, the equation is

y = 400 + 10x

700

Initial = 700

Spending = 20

So, the equation is

y = 700 - 20x

When they both have the same amount of money in the bank, we have

700 - 20x = 400 + 10x

Evaluate the like terms

30x = 300

Divide by 30

x = 10

Hence, they will both have the same amount in the bank after 10 weeks

We need to consider the general problem: \[-(ku')' + cu' + bu = f\]If we discretize by the finite element method with four elements.

On the first and last elements, we use linear shape functions, and on the middle two elements, we use quadratic shape functions. The resulting basis functions are given by:The basis functions ϕ1 and ϕ4 are linear while ϕ2 and ϕ3 are quadratic in nature. These basis functions are such that they follow the property of linearity and quadratic nature on each of the elements.

For the structure of the stiffness matrix K, we need to consider the discrete problem given by \[KU=F\]where U is the vector of nodal values of u, K is the stiffness matrix and F is the load vector. Considering the above equation and assuming constant values of k and c on each of the element we can write\[k_{1}\begin{bmatrix}1 & -1\\-1 & 1\end{bmatrix}+k_{2}\begin{bmatrix}2 & -2 & 1\\-2 & 4 & -2\\1 & -2 & 2\end{bmatrix}+k_{3}\begin{bmatrix}2 & -1\\-1 & 1\end{bmatrix}\]Here, the subscripts denote the element number. As we can observe, the resulting stiffness matrix K is symmetric and has a banded structure.

The element [1 1] and [2 2] are common to two elements while all the other elements are present on a single element only. Hence, we have four elements with five degrees of freedom. Thus, the stiffness matrix will be a 5 x 5 matrix and the structure of K is as follows:

$$\begin{bmatrix}k_{1}+2k_{2}& -k_{2}& & &\\-k_{2}&k_{2}+2k_{3} & -k_{3} & & \\ & -k_{3} & k_{1}+2k_{2}&-k_{2}& \\ & &-k_{2}& k_{2}+2k_{3}&-k_{3}\\ & & & -k_{3} & k_{3}+k_{2}\end{bmatrix}$$Conclusion:In this question, we considered the general problem given by -(ku')' + cu' + bu = f. We discretized it by the finite element method with four elements. On the first and last elements, we used linear shape functions, and on the middle two elements, we used quadratic shape functions. We sketched the resulting basis functions. The structure of the stiffness matrix K was then determined by ignoring boundary conditions. We observed that it is symmetric and has a banded structure.

\(\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)\)

Let assume that

\(\rm :\longmapsto\:y = {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)\)

We know,

\(\boxed{\tt{ {cosec}^{ - 1}x = {sin}^{ - 1}\bigg( \dfrac{1}{x} \bigg)}}\)

So, using this, we get

\(\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2x}{1 + {x}^{2} } \bigg)\)

Now, we use Method of Substitution, So we substitute

\( \red{\rm :\longmapsto\:x = tanz \: \rm\implies \:z = {tan}^{ - 1}x}\)

So, above expression can be rewritten as

\(\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2tanz}{1 + {tan}^{2} z} \bigg)\)

\(\rm :\longmapsto\:y = sin^{ - 1} \bigg( sin2z \bigg)\)

\(\rm\implies \:y = 2z\)

\(\bf\implies \:y = 2 {tan}^{ - 1}x\)

So,

\(\bf\implies \: {cosec}^{ - 1}\bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = 2 {tan}^{ - 1}x\)

Thus,

\(\rm :\longmapsto\:\dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)\)

\(\rm \:  =  \: \dfrac{d}{dx}(2 {tan}^{ - 1}x)\)

\(\rm \:  =  \: 2 \times \dfrac{1}{1 + {x}^{2} } \)

\(\rm \:  =  \: \dfrac{2}{1 + {x}^{2} } \)

Hence,

The velocity of the center of mass of the system is -9.16\(\hat{i}\) - 4.26\(\hat{j}\) m/s.

We must compute the weighted average of the velocities of the two masses in order to determine the velocity of the system's center of mass.

The equation: gives the center of mass's velocity (\(V_{cm}\)):

\(V_{cm}\) = (\(m_{A}\) × \(v_{A}\) + \(m_{B}\) × \(v_{A}\))/(\(m_{A}\) + \(m_{B}\))

\(m_{A}\) = 31 kg(mass of A)

\(m_{B}\) = 30 kg(mass of B)

\(v_{A}\) = 11\(\hat{i}\) - 20\(\hat{j}\) (velocity of A)

\(v_{B}\) = -30\(\hat{i}\) + 12\(\hat{j}\) (velocity of B)

Substituting the given values into the equation, we have:

\(V_{cm}\) = (31 kg × (11\(\hat{i}\) - 20\(\hat{j}\)) + 30 kg × (-30\(\hat{i}\) + 12\(\hat{j}\)))/(31 kg + 30 kg)

Simplifying the expression, we get:

\(V_{cm}\) = (341\(\hat{i}\) - 620\(\hat{j}\) - 900\(\hat{i}\) + 360\(\hat{j}\))/61 kg

\(V_{cm}\) = (-559\(\hat{i}\) - 260\(\hat{j}\))/61 kg

Therefore, the velocity of the center of mass of the system is approximately -9.16\(\hat{i}\) - 4.26\(\hat{j}\) m/s.

Answer: The height of the tree is 35.4 ft.

Step-by-step explanation:

14.16/1.2 = 11.8

3 * 11.8 = 35.4

we need to multiply this number by 100 to get the  as a percentage:

0.1806 * 100 = 18.06%

The probability of choosing a senior can be calculated using the formula:

P(senior) = (102/562) * 100

P(senior) = 18.06%

This means that there is an 18.06% chance of choosing a senior if a student is randomly selected from the school.

First, we need to calculate the total number of students in the school by adding together the number of students in each class:

Total = 165 + 145 + 114 + 102 = 562

Next, we need to calculate the probability of choosing a senior by taking the number of seniors enrolled in the school (102) and dividing it by the total number of students in the school (562).

102/562 = 0.1806

Finally, we need to multiply this number by 100 to get the probability as a percentage:

The length of BC is B. 2.20 cm

As per the known fact, the linear angle is 180°. As per this writing the equation -

∠ BC + 168 = 180

∠ BC = 180 - 168

∠ BC = 12°

Now, using formula  for calculation of length of arc -

Length = angle/360×2πr, where r refers to radius

Calculating radius as -

Radius = diameter ÷ 2

Radius = 21 ÷ 2

Radius = 10.5 centimeters

Now keep the values in formula to find the length of arc, which is the value of BC

Length = 12/360×2×3.14×10.5

Length = 252×3.14/360

Length = 2.2 centimeters

The Maclaurin series for the following function determines its radius of convergence r. f(x) = ln 1 x 1 − x converges on the interval (-1, 1).

To find the Maclaurin series for f(x) = ln(1-x)/(1-x), we first note that this function is equal to the derivative of ln(1-x) with respect to x. Therefore, the Maclaurin series for f(x) converges on the interval (-1, 1).

Using the power series expansion for ln(1-x), we have:

ln(1-x) = -x - x^2/2 - x^3/3 - ...

f(x) = (1/(1-x))(-1 - x - x^2/2 - x^3/3 - ...) * (1/(1-x))

f(x) = -1 - 2x - 3x^2 - 4x^3 - ...

Since the limit is equal to 1, the radius of convergence is:

r = 1/lim n->infinity |a(n+1)/a(n)| = 1/1 = 1

Therefore, the Maclaurin series for f(x) converges on the interval (-1, 1).

This integral will give us the volume of the solid under the surface z = 1 + x²y² and above the region enclosed by x = y² and x = 4.

The summing of discrete data is indicated by the integration. To determine the functions that will characterize the area, displacement, and volume that result from a combination of small data that cannot be measured separately, integrals are calculated.

To find the volume of the solid under the surface z = 1 + x²y² and above the region enclosed by x = y² and x = 4, we can set up a double integral over the given region.

First, let's find the limits of integration for the variables x and y by considering the given equations x = y² and x = 4.

The region enclosed by x = y² and x = 4 can be visualized as a parabolic shape between x = 4 and x = 16 (since 4 is the square of 2, and 16 is the square of 4).

So, the limits of integration for x are from 4 to 16.

For each x value within this range, the limits of integration for y will be from the lower curve y = √x to the upper curve y = √4 = 2 (since the parabolic shape is symmetric about the y-axis).

Therefore, the limits of integration for y are from √x to 2.

Now we can set up the double integral:

∬(R) (1 + x²y²) dy dx,

where R represents the region of integration.

Integrating with respect to y first, the inner integral becomes:

∫[√x, 2] (1 + x²y²) dy,

Integrating this with respect to y gives:

[y + (x²y³)/3] evaluated from √x to 2.

Substituting the limits of integration:

[(2 + (8x²)/3) - (√x + (x²√x)/3)],

Now, we integrate this expression with respect to x:

∫[4, 16] [(2 + (8x²)/3) - (√x + (x²√x)/3)] dx.

Evaluating this integral will give us the volume of the solid under the surface z = 1 + x²y² and above the region enclosed by x = y² and x = 4.

The librarian can purchase at most 1100 paperback books and no hardback books; 191 hardback books and no paperback books; or 336 paperback books and 156 hardback books for a total cost of $4,400. in discount.

Let x be the number of paperback books and y be the number of hardback books that the head librarian at the Washington County Library will purchase in discount.

The total amount spent is given by the equation 4x + 23y. She has at most $4,400 to spend on the books.The constraint is given by the equation 4x + 23y ≤ 4400. Let's plot this constraint in the xy-plane below:To determine the vertices of the feasible region, we solve the system of equations4x + 23y = 4400y = 0x = 0The two equations above give the coordinates of the point (0, 0).

Now, we have two more systems of equations to solve. They are4x + 23y = 4400 and y = 0.Substituting y = 0 in the first equation above, we get4x + 0 = 4400, which gives x = 1100. Thus, the first point is (1100, 0).4x + 23y = 4400 and x = 0.Substituting x = 0 in the first equation above, we get0 + 23y = 4400, which gives y = 191.304... ≈ 191. Therefore, the second point is (0, 191).Now we are left with only one equation:4x + 23y = 4400.We solve for y in this equation:4x + 23y = 440023y = 4400 - 4xy = (4400 - 4x)/23.The third point is found by solving this equation. We get y ≈ 156.174, x ≈ 336.57 ≈ 337.The third point is approximately (337, 156).

The feasible region is the shaded triangle bounded by the lines x = 0, y = 0, and 4x + 23y = 4400:
