The standard matrix of the linear transformation "t" is a 4x2 matrix given by [9 -7] [1  2] [9  0] [1  0]

In this problem, we are given that "t" is a linear transformation from ℝ2 to ℝ4. A linear transformation can be represented by a matrix, where the columns of the matrix are the images of the basis vectors. In this case, we have the images of the basis vectors e1 and e2, te1 and te2, respectively.

Since e1=(1,0) and e2=(0,1), we can use the images te1 and te2 to construct the standard matrix of "t". The first column of the matrix corresponds to te1, which is (9, 1, 9, 1), and the second column corresponds to te2, which is (-7, 2, 0, 0).

Therefore, the standard matrix of "t" is the 4x2 matrix shown above, where each column represents the image of the corresponding basis vector.

To find the absolute maximum of the function f(x) = 1 - 3x^2 + 18x in the interval [0, 5], we need to evaluate the function at the critical points and endpoints of the interval.

First, we find the critical points by taking the derivative of f(x) and setting it equal to zero:

f'(x) = -6x + 18 = 0.

Solving this equation, we get x = 3 as the critical point.

Next, we evaluate f(x) at the endpoints of the interval:

f(0) = 1 - 3(0)^2 + 18(0) = 1,

f(5) = 1 - 3(5)^2 + 18(5) = 46.

Finally, we evaluate f(x) at the critical point:

f(3) = 1 - 3(3)^2 + 18(3) = 10.

Comparing the values, we can see that the absolute maximum of f(x) in the interval [0, 5] is f(5) = 46.

Therefore, the correct answer is (C) f(5).

To find the absolute maximum of the function f(x) = 1 - 3x^2 + 18x in the interval [0, 5], we evaluate the function at the critical points and endpoints of the interval.

The critical points are the points where the derivative of the function is either zero or undefined. To find the derivative of f(x), we differentiate the function with respect to x:

f'(x) = -6x + 18.

Setting f'(x) = 0, we solve for x: -6x + 18 = 0, which gives x = 3.

Now we evaluate f(x) at the critical point x = 3 and the endpoints of the interval:

f(0) = 1 - 3(0)^2 + 18(0) = 1,

f(3) = 1 - 3(3)^2 + 18(3) = 1 - 27 + 54 = 28,

f(5) = 1 - 3(5)^2 + 18(5) = 1 - 75 + 90 = 16.

Comparing these values, we find that the absolute maximum of f(x) in the interval [0, 5] is f(3) = 28, which corresponds to option (B).

The arc length of the curve r = θ² over the interval 0 ≤ θ ≤ 2π is 2π√5. The arc length formula for polar curves: L = ∫[a,b] √(r(θ)²+ (dr(θ)/dθ)²) dθ

To find the arc length of the curve r = θ²over the interval 0 ≤ θ ≤ 2π, we can use the arc length formula for polar curves:

L = ∫[a,b] √(r(θ)²+ (dr(θ)/dθ)²) dθ

In this case, r(θ) = θ^2, and we need to find the arc length for 0 ≤ θ ≤ 2π. Let's calculate it step by step:

1. Find dr(θ)/dθ:

  dr(θ)/dθ = d/dθ(θ²) = 2θ

2. Plug the values into the arc length formula:

  L = ∫[0,2π] √(θ² + (2θ)²) dθ

    = ∫[0,2π] √(θ² + 4θ²) dθ

    = ∫[0,2π] √(5θ²) dθ

    = ∫[0,2π] √(5)θ dθ

3. Simplify the integrand:

  √(5)θ dθ = √(5) * ∫[0,2π] θ dθ

4. Integrate ∫θ dθ:

  ∫θ dθ = (1/2)θ²

5. Evaluate the integral at the limits of integration:

  L = √(5) * [(1/2)(2π)² - (1/2)(0)²]

    = √(5) * [(1/2)(4π²)]

    = 2π√(5)

Therefore, the arc length of the curve r = θ² over the interval 0 ≤ θ ≤ 2π is 2π√(5).

The integral of 28sin(3t)cos²(3t)dt is equal to -7/36([tex]cos^3[/tex](3t)) + C, where C is the constant of integration.

To solve the integral, we can use the power reduction formula for cosine: cos²(x) = (1 + cos(2x))/2. Substituting this into the integral, we have:

∫28sin(3t)cos²(3t)dt = ∫28sin(3t)(1 + cos(2(3t))/2)dt

Expanding the term inside the integral, we get:

= ∫(28sin(3t) + 14sin(3t)cos(6t))dt

We can split this integral into two separate integrals:

= ∫28sin(3t)dt + ∫14sin(3t)cos(6t)dt

The first integral can be easily evaluated as -28/3cos(3t). To evaluate the second integral, we can use the product-to-sum formula:

sin(a)cos(b) = (1/2)(sin(a + b) + sin(a - b)).

Applying this formula, we have:

∫14sin(3t)cos(6t)dt = 14/2∫(sin(3t + 6t) + sin(3t - 6t))dt

= 7/2∫sin(9t)dt + 7/2∫sin(-3t)dt

= -7/18cos(9t) - 7/6cos(3t)

Combining the results of the two integrals, we have:

∫28sin(3t)cos²(3t)dt = -28/3cos(3t) - 7/18cos(9t) - 7/6cos(3t) + C

= -7/36([tex]cos^3[/tex](3t)) + C,

To evaluate the indefinite integral of ∫ sin(3x)cos(x) dx, we can use integration by parts. The integration by parts formula states that ∫ u dv = uv - ∫ v du, where u and v are differentiable functions.

Let's choose u = sin(3x) and dv = cos(x) dx. Taking the derivatives and integrals, we have du = 3cos(3x) dx and v = sin(x).

Using the integration by parts formula, we can rewrite the integral as ∫ sin(3x)cos(x) dx = -cos(x)sin(3x) + ∫ cos(3x)3cos(x) dx.

Simplifying the expression, we have ∫ sin(3x)cos(x) dx = -cos(x)sin(3x) + 3∫ cos^2(3x) dx.

Now, we can use the identity cos^2(θ) = (1 + cos(2θ))/2. Applying this identity to our integral, we have ∫ sin(3x)cos(x) dx = -cos(x)sin(3x) + 3/2 ∫ (1 + cos(6x)) dx.

The equation that represents the set of points P(x, y, z) that are twice as far from A(0, -1, 1) as from B(1, 2, 0) is:

√((x - 0)^2 + (y - (-1))^2 + (z - 1)^2) = 2√((x - 1)^2 + (y - 2)^2 + (z - 0)^2)

Let's break down the process to understand how this equation is derived.

First, we calculate the distance between a point P(x, y, z) and point A(0, -1, 1) using the distance formula in 3D space:

d1 = √((x - 0)^2 + (y - (-1))^2 + (z - 1)^2)

Similarly, we calculate the distance between the same point P(x, y, z) and point B(1, 2, 0):

d2 = √((x - 1)^2 + (y - 2)^2 + (z - 0)^2)

According to the given condition, the points should be twice as far from A as from B. Mathematically, this can be expressed as:

d1 = 2d2

Substituting the expressions for d1 and d2:

√((x - 0)^2 + (y - (-1))^2 + (z - 1)^2) = 2√((x - 1)^2 + (y - 2)^2 + (z - 0)^2)

This equation represents the set of points that are twice as far from A(0, -1, 1) as from B(1, 2, 0).

The set of points described by this equation forms a surface called a hyperboloid of one sheet. A hyperboloid of one sheet is a three-dimensional surface that resembles two opposing cones connected at their tips.

The volume of the solid under [tex]z = 3x + 5y^2[/tex] and above the region bounded by y = x and y = 4x in the first quadrant is (5/6) cubic units. The volume of the solid bounded by [tex]z = 16 - 22 - y^2[/tex] and [tex]z = x^2 + y^2 - 16[/tex] is (224/15)π cubic units. The area enclosed by r = cos(3θ) and the cardioid r = 1 + cos(θ) is (11/6)π square units.

To find the volume of the solid under the surface [tex]z = 3x + 5y^2[/tex] and above the region bounded by y = x and y = 4x, we can set up the integral in polar coordinates. The limits for the radius, r, can be determined by solving the equations y = x and y = 4x in polar coordinates, which gives us rcos(θ) = rsin(θ) and rcos(θ) = 4rsin(θ), respectively.

Solving these equations yields r = 0 and r = 4/(sin(θ) - cos(θ)). Integrating the function 3r(cos(θ)) + 5(r²)(sin(θ))² with respect to r from 0 to 4/(sin(θ) - cos(θ)) and integrating with respect to θ from 0 to π/4, the volume is given by the double integral of the function, which evaluates to (5/6) cubic units.

For the volume of the solid bounded by the paraboloids [tex]z = 16 - 22 - y^2[/tex]and [tex]z = x^2 + y^2 - 16[/tex], we need to find the intersection curves of the two surfaces in polar coordinates. Setting the two equations equal to each other and simplifying gives [tex]y^2 = x^2 + 6[/tex]. By substituting r²sin²(θ) for y²and [tex]r^2cos^2([/tex]θ) for x², we obtain r²sin²(θ) = r²cos²(θ) + 6. Rearranging the equation gives r = √(6/(sin²(θ) - cos²(θ))).

To find the limits of integration for θ, we set sin²(θ) - cos²(θ) = 0, which yields sin²(θ) = cos²(θ). This occurs when θ = π/4 or θ = 3π/4. Integrating the function (16 - 22 - r²sin²(θ)) - (r²cos²(θ) - 16) with respect to r from 0 to √(6/(sin²(θ) - cos²(θ))) and integrating with respect to θ from π/4 to 3π/4, the volume evaluates to (224/15)π cubic units.

To find the area enclosed by r = cos(3θ) and the cardioid r = 1 + cos(θ), we need to determine the intersection points of the two curves. Setting r = cos(3θ) equal to r = 1 + cos(θ) gives cos(3θ) = 1 + cos(θ). Simplifying this equation yields 4cos^3(θ) - 3cos(θ) = 1.

By graphing or applying numerical methods, we find the values of θ that satisfy this equation, which are θ = π/6 and θ = 5π/6. Integrating the function r with respect to θ from π/6 to 5π/6, the area enclosed by the curves is given by the integral of r²/2 with respect to θ, which evaluates to (11/6)π square units.

Based on this assumption, the estimated population 25 years after the town council started tracking the population data would be approximately  82,150 people.

To estimate the population of the town 25 years after the town council started tracking the population data, we need to know the growth rate of the town's population. If we have the growth rate, we can use it to project the population in the future.

Assuming a constant growth rate, we can use the exponential growth formula:

P = P0 * (1 + r)^t

where P is the future population, P0 is the initial population, r is the growth rate, and t is the time in years.

Since we don't have the growth rate or the initial population, we cannot provide an exact answer. However, we can make an estimate based on assumptions.

If we assume a certain annual growth rate, we can apply it to the current population. Let's say the current population is 50,000 people. We can plug in the values into the formula as follows:

P = 50,000 * (1 + r)^25

This equation will give us an estimate of the population 25 years into the future based on the assumed growth rate. To obtain a rounded estimate to the nearest 100 people, we can round the result to the nearest hundred.

For example, if we assume a 2% annual growth rate:

P = 50,000 * (1 + 0.02)^25 ≈ 50,000 * 1.643 = 82,150

The volume of the solid formed by rotating the region bounded by the lines y = 2 - x, y = 2 - 2x, and y = 0 about the line x = 3 can be found using the method of cylindrical shells.

To find the volume using cylindrical shells, we integrate the circumference of each shell multiplied by its height and thickness. In this case, the shells are formed by rotating the region bounded by the lines y = 2 - x, y = 2 - 2x, and y = 0 about the line x = 3.

To set up the integral, we consider a small vertical strip of thickness dx at a distance x from the line x = 3. The height of the strip is given by the difference between the upper and lower curves, which is (2 - x) - (2 - 2x) = x.

The circumference of the shell is given by 2π times the distance from the axis of rotation (x = 3). Hence, the circumference is 2π(3 - x). The volume of each shell is then given by the product of the circumference and height: 2π(3 - x) * x * dx.

To calculate the total volume, we integrate this expression from the lower limit of x = 0 to the upper limit of x = 1, as these are the x-values where the curves intersect. Evaluating the integral will give us the volume of the solid formed by rotating the given region about x = 3.

The equation of the vertical asymptote is x = 1.

Given functions are:f(x) = log(y(13x + 8y - 2)),h(x) = log3|x|,g(x) = |log5(x)|.

We are supposed to find the domain and range of each function and the equation of the vertical asymptote of g(x).

Domain and range of f(x): Domain of f(x) is all the values of x for which (13x + 8y - 2) > 0, as log is defined only for positive values, or y > 2/8 - 13x/8 or y > (2 - 13x)/8.

So, the domain of f(x) is the set of all real numbers such that (2 - 13x)/8 < y.

Range of f(x) is all the real numbers. As for every value of x, y can take all the real numbers.

Domain and range of h(x): Domain of h(x) is the set of all the values of x for which |x| > 0 or x < 0 or x > 0.

So, the domain of h(x) is (-∞, 0) U (0, ∞).

As |x| > 0, the range of h(x) is all the real numbers or (-∞, ∞).

Domain and range of g(x): Domain of g(x) is the set of all values of x for which |log5(x)| exists.

As log5(x) exists only for positive values of x, |log5(x)| exists for x > 0.

The domain of g(x) is (0, ∞).

As |log5(x)| can take all the real numbers, the range of g(x) is (-∞, ∞).

Equation of vertical asymptote of g(x): For the equation of vertical asymptote, the denominator of a function should be zero, and the numerator should not be zero.

Here, the denominator is not x, but |log5(x)|.If log5(x) = 0,x = 1. So, we have a vertical asymptote at x = 1.

To find the expression for (f(x + h) - f(x)) / h for the function f(x) = -x² - 2x - 4, we substitute f(x + h) and f(x) into the formula and simplify the expression.

Using the derivative formula we derive the expression.We start by evaluating f(x + h) and f(x) individually. For f(x + h), we substitute x + h into the function: f(x + h) = -(x + h)² - 2(x + h) - 4. Expanding and simplifying, we get f(x + h) = -x² - 2hx - h² - 2x - 2h - 4.

Next, we substitute x into the function f(x): f(x) = -x² - 2x - 4.

Now, we can calculate the numerator of our expression, f(x + h) - f(x). Substituting the corresponding values, we have (-x² - 2hx - h² - 2x - 2h - 4) - (-x² - 2x - 4). Simplifying this expression, we get -2hx - h² - 2h.

Finally, we divide the numerator by h to get our desired expression: (-2hx - h² - 2h) / h. By canceling out h terms, we simplify it further to -2x - h - 2. Thus, the expression (f(x + h) - f(x)) / h for f(x) = -x² - 2x - 4 is -2x - h - 2.

The relative rate of change for the function f(t) = 15√t - 2, we need to take the derivative of f(t) with respect to t. Therefore, the relative rate of change at t = 6 is approximately 0.374.

To find the relative rate of change for the function f(t) = 15√t - 2, we need to take the derivative of f(t) with respect to t.

Taking the derivative, we have:

f'(t) = (15/2) * (1/√t)

The relative rate of change is given by the absolute value of the derivative divided by the function itself. So, the relative rate of change is:

Relative rate of change = |f'(t)/f(t)|

Substituting the values into the formula, we get:

Relative rate of change = |(15/2) * (1/√t) / (15√t - 2)|

Simplifying further, we have:

Relative rate of change = |1 / (2√t - (2/15√t))|

Now, to evaluate the relative rate of change at t = 6, we substitute t = 6 into the relative rate of change equation:

Relative rate of change at t = 6 = |1 / (2√6 - (2/15√6))|

Calculating the expression, we get:

Relative rate of change at t = 6 = |1 / (2√6 - (2/15√6))| ≈ 0.374

Therefore, the relative rate of change at t = 6 is approximately 0.374.

The limiting amount of salt in the tank as t goes to infinity is:(C(0) + (γ/30)) × 0 - (γ/30) = - (γ/30) grams or zero.The limiting amount of salt in the tank as t goes to infinity is zero.

Let C(t) be the concentration of salt at time t, V(t) be the volume of the mixture at time t, and m(t) be the amount of salt in the mixture at time t.Step 1:We know that 2 liters of the mixture enter and exit the tank at the same rate. Therefore, the volume V(t) in the tank is constant.V(t)

= 120 liters for all t.Step 2:Let us consider a small time interval, dt.The amount of salt entering the tank in dt minutes is:2 × γ g/liter × 2 liters/min × dt

= 4γdt g  The amount of salt leaving the tank in dt minutes is:C(t) × 2 liters/min × dt

= 2C(t)dt g Therefore, the increase in the amount of salt in the tank during dt minutes is:d[m(t)]

= (4γdt - 2C(t)dt) gStep 3:Integrating this expression with respect to t, we get:m(t)

= 4γt - 2 ∫[C(t)]dt Where the integral is taken over time 0 to time t.Step 4:We know that V(t)

= 120 liters for all t.Therefore, the concentration C(t) is given by:C(t)

= m(t)/V(t)

= (4γt - 2 ∫[C(t)]dt) / 120 liters Simplifying, we get:120C(t) + 2 ∫[C(t)]dt

= 4γtWe can differentiate this expression with respect to t to obtain a differential equation that governs C(t).Differentiating, we get:120(dC(t)/dt) + 2C(t)

= 4γOr, dC(t)/dt + (1/60)C(t)

= γ/30This is a first-order linear differential equation.Step 5:Solving this differential equation using an integrating factor, we get:C(t)

= (C(0) + (γ/30))(e^(-t/60)) - (γ/30)where C(0) is the initial concentration of salt in the tank.Step 6:As t approaches infinity, the exponential term e^(-t/60) approaches zero. The limiting amount of salt in the tank as t goes to infinity is:(C(0) + (γ/30)) × 0 - (γ/30)

The derivative of f(z) is  found to be f'(z) = [z⁵+i(z²-3z²sin(1/z) - 2z cos(1/z))]/(z³+i)².

Given function:

f(z)=z⋅sin(1/z )/ z^3+i 1)

Domain of the function:

Here, we see that the denominator of the function is `z^3 + i`,

where i is the imaginary unit, and therefore never equals zero.

Hence, the domain of f(z) is all complex numbers, i.e. f(z) is defined for all z ∈ C.

2) Cauchy-Riemann equations:

Let us consider f(z) = u(x,y) + iv(x,y),

where u(x,y) is the real part and v(x,y) is the imaginary part of f(z).

The Cauchy-Riemann equations are as follows:

∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x

Differentiability: Now, we'll show that the function f(z) is differentiable by verifying that it satisfies the Cauchy-Riemann equations.

We have,

`f(z) = z⋅sin(1/z )/ z^3+i`.

Let us express this in terms of its real and imaginary parts, i.e.

`f(z) = u(x,y) + iv(x,y)`.

We have:

u(x,y) = x sin(1/x² + y²)/(x³ + y³)i

(x,y) = y sin(1/x² + y²)/(x³ + y³)

Using the Cauchy-Riemann equations, we get:

∂u/∂x = sin(1/x² + y²)/(x²(x³ + y³)) - 3x²y²sin(1/x² + y²)/(x⁴ + 2x²y² + y⁴)

∂v/∂y = sin(1/x² + y²)/(y²(x³ + y³)) - 3x²y²sin(1/x² + y²)/(x⁴ + 2x²y² + y⁴)

∂u/∂y = (2xy)/(x³ + y³)cos(1/x² + y²) - 3xy²sin(1/x² + y²)/(x⁴ + 2x²y² + y⁴)

∂v/∂x = (2xy)/(x³ + y³)cos(1/x² + y²) - 3x²y sin(1/x² + y²)/(x⁴ + 2x²y² + y⁴)

It can be shown that ∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x for all z ≠ 0.

Therefore, f(z) satisfies the Cauchy-Riemann equations and is differentiable at all points in its domain.

Analyticity: Since f(z) is differentiable at all points in its domain, it is analytic.

Derivative of the function: Using the quotient rule of differentiation, we get:

f'(z) = [z³+i(3z²) - (z⋅sin(1/z)(3z²-2z))]/(z³+i)²

= [z⁵+i(z²-3z²sin(1/z) - 2z cos(1/z))]/(z³+i)²
