To find the power series expansion about x=0 for the general solution to the given differential equation, let's assume a power series solution of the form:

w(x) = ∑(n=0 to ∞) a_n x^n

where a_n represents the coefficients of the power series.

Differentiating w(x) with respect to x, we have:

w'(x) = ∑(n=0 to ∞) a_n*n*x^(n-1) = ∑(n=1 to ∞) a_n*n*x^(n-1)

Differentiating w'(x) with respect to x, we have:

w''(x) = ∑(n=1 to ∞) a_n*n*(n-1)*x^(n-2) = ∑(n=0 to ∞) a_(n+2)*(n+2)*(n+1)*x^n

Now, substituting these expressions into the differential equation, we get:

∑(n=0 to ∞) a_(n+2)*(n+2)*(n+1)*x^n - 8x^2 * ∑(n=1 to ∞) a_n*n*x^(n-1) + ∑(n=0 to ∞) a_n*x^n = 0

To simplify this equation, we need to separate the terms and adjust the indices:

a_2*2*1 + a_3*3*2*x + ∑(n=2 to ∞) a_(n+2)*(n+2)*(n+1)*x^n - 8∑(n=1 to ∞) a_n*n*x^n + ∑(n=0 to ∞) a_n*x^n = 0

Grouping the terms with the same power of x, we have:

[2a_2 - 8a_1] + [6a_3 - 8a_2]x + ∑(n=2 to ∞) [a_(n+2)*(n+2)*(n+1) - 8a_n*n]x^n + ∑(n=0 to ∞) a_n*x^n = 0

Equating the coefficients of each power of x to zero, we can find the expressions for a_2, a_3, and the terms up to order 3:

2a_2 - 8a_1 = 0  =>  a_2 = 4a_1

6a_3 - 8a_2 = 0  =>  a_3 = (8/6)*a_2 = (8/6)*4a_1 = (16/3)a_1

The terms up to order 3 are:

a_0 + a_1*x + 4a_1*x^2 + (16/3)a_1*x^3

The rate of change of volume dV/dt when the height is 1 cm is approximately equal to -2,820 π/3 cm³/h.

Let V be the volume of the block of ice, h be the height of the block of ice, and r be the radius of the block of ice. It is given that r = 30 cm, h = 10 cm, and dh/dt = -2 cm/h. We need to find the rate of change of volume dV/dt when the height is 1 cm.

To find the rate of change of volume dV/dt, we can use the chain rule of differentiation.

dV/dt = dV/dh × dh/dt

We know that the volume of a right circular cone is given by:

V = 1/3 πr²h

When the radius is constant, we get:

dV/dh = 1/3 πr²dh/dh = 1/3 πr²

Also, we know that dh/dt = -2 cm/h.

Substituting the values of r, h, and dh/dt in the formula for dV/dt, we get:

dV/dt = (1/3 × π × (30)²) × (-2)= -2,820 π/3

The rate of change of volume is approximately equal to -2,820 π/3 cm³/h. The negative sign shows that it is decreasing.

Answer:

  g(2a) = 8a

Step-by-step explanation:

Put the argument where the variable is and simplify.

  g(a) = 4a

  g(2a) = 4(2a) = 8a

  g(2a) = 8a

(A) dA/dt = 0.02A - 1000

    A(0) = $24,500

(B) A = (1000 ± Ke^t) / 0.02

(C) t = ln(1000 / K) years

(A) To write the differential equation (DE) model for the time rate of change of money in the account, we consider that the money in the account is continuously compounded with an annual interest rate of 2%. The rate of change of money in the account, dA/dt, is given by the difference between the continuous deposit and the continuous withdrawal.

dA/dt = 0.02A - 1000

Here, 0.02A represents the continuous interest earned on the account balance, and 1000 represents the continuous withdrawal.

The initial condition is A(0) = $24,500, as given in the problem.

(B) To solve the initial value problem (IVP) and find the amount of money in the account as a function of time, we can separate variables and integrate the differential equation:

1/(0.02A - 1000) dA = dt

Integrating both sides:

∫(1/(0.02A - 1000)) dA = ∫dt

Applying integration, we get:

ln(|0.02A - 1000|) = t + C

where C is the constant of integration.

Taking the exponential of both sides:

|0.02A - 1000| = e^(t + C)

Since the constant of integration C can be positive or negative, we can rewrite the equation as:

0.02A - 1000 = ±e^t * e^C

Simplifying further:

0.02A - 1000 = ±Ke^t

Here, K represents the constant resulting from combining the constants e^C.

Solving for A, we have:

0.02A = 1000 ± Ke^t

A = (1000 ± Ke^t) / 0.02

(C) To determine when the money will run out, we set A(t) = 0 and solve for t:

(1000 ± Ke^t) / 0.02 = 0

1000 ± Ke^t = 0

±Ke^t = -1000

Since e^t is always positive, the equation implies that K must be negative to satisfy the equation. Thus, we can rewrite it as:

-Ke^t = -1000

Dividing both sides by -K, we get:

e^t = 1000 / K

Taking the natural logarithm of both sides:

t = ln(1000 / K)

Therefore, the money will run out at t = ln(1000 / K) years.

In programming, a loop is a control structure that allows us to execute a block of code repeatedly. A for loop is a type of loop that is commonly used when we need to repeat a set of instructions for a specific number of times.

In this case, we want to print the integers 0 through 39, each value on a separate line.

Here's an example of a for loop in Python that accomplishes this:

for i in range(40):

   print(i)

In this loop, the variable `i` takes on the values 0 through 39, one at a time, on each iteration of the loop. The range(40) function generates a sequence of integers from 0 to 39, which is used to control the loop.

The print() function outputs the value of `i` to the console on each iteration, followed by a newline character which creates a new line for each value.

To break this down further, the 'for' keyword initiates the loop and the `in` keyword specifies the range of values for the loop. The `range()` function generates a sequence of integers starting at 0 and ending at 39.

The `print()` function outputs each value to the console followed by a newline character which creates a new line for each value. This loop will execute a total of 40 times, printing each value on a separate line.

In summary, the for loop is a powerful and flexible tool in programming that allows us to automate repetitive tasks. In this example, we used a for loop to print the integers 0 through 39, each on a separate line, in a concise and efficient manner.

a)  Yes, V is a function of x.

b) V(11)  = 9680 in³ ; V(23) = 5290 in³

c) domain is [0, 27].

Given

V = x²(135 - 5x), where x is the length of each side of the cross section (in inches).

(a) Yes, V is a function of x.

To prove it, check whether each value of x gives a unique value of V.

If every value of x corresponds to a unique value of V, then it is a function of x.

(b) If V = V(x), V(11) and V(23) are :

To find V(11), substitute x = 11 in V(x) equation.

V(11) = 11²(135 - 5 * 11)

= 11²(80)

= 9680 in³

To find V(23), substitute x = 23 in V(x) equation.

V(23) = 23²(135 - 5 * 23)

= 23²(10)

= 5290 in³

(c) Since it is not possible to have a negative length of a side of a box, x cannot be negative.

Therefore, the domain must be x ≥ 0.

Also, the volume of a box cannot be negative, so we set V(x) ≥ 0.

Therefore,

x²(135 - 5x) ≥ 0

x(135 - 5x) ≥ 0

x(5x - 135) ≤ 0

x ≤ 0 or x ≤ 27

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The given quadratic function f(x) = -0.5x² + 10 models the height of the archway at a distance of x feet from the center of the arch.

Since the archway has vertical sides, the maximum height of the archway occurs at its center, which is the vertex of the parabolic function.

The x-coordinate of the vertex of a quadratic function f(x) = ax² + bx + c is given by -b/2a.

In this case, the quadratic function is f(x) = -0.5x² + 10, so its vertex is at x = -b/2a = -0 / (2 * (-0.5)) = 0.

Therefore, the maximum height of the archway occurs at x = 0.

Substituting x = 0 into the quadratic function f(x) = -0.5x²+ 10, we get:

f(0) = -0.5(0)² + 10 = 10

Therefore, the height of the archway at its center is 10 feet.

Since the archway has vertical sides, its height will be 10 feet at a distance of 0 feet from the center on both sides.

We need to find the horizontal distance between the two points where the height of the archway is also 10 feet.

Substituting f(x) = 10 into the quadratic function f(x) = -0.5x² + 10, we get:

10 = -0.5x² + 10

Simplifying this equation, we get:

x² = 20

Taking the square root of both sides, we get:

x = ±√(20) ≈ ±4.47

Therefore, the two points where the height of the archway is 10 feet are at x = -4.47 and x = 4.47. The distance between these two points is:

distance = 2 * 4.47 = 8.94 feet (rounded to two decimal places)

Therefore, the walls of the archway are approximately 8.94 feet apart.

Find the diagram attached

From the diagram

<PQT =<TRS = 40

Since the triangle STR is isosceles, here,

<TSR =<TRS = 40

Also the sum of angle in a triangle is 189, hence:

Arc SR+<TSR +<TRS = 18₩

ArcSR +40+40=180

ArcSR +80=180

ArcSR = 180-80

ArcSR = 100degrees

Hence the measure of SR is 100degrees

The measure of arc SR is 100°. The correct option is the third option - 100°

From the question, we are to determine the measure of arc SR.

The measure of arc SR = <STR

Now, we will determine the measure of <STR

In the diagram, T is the center of the circle.

∴ TP and TQ are radii.

Then, we can conclude that ΔPQT is an isosceles triangle.

Recall: Base angles of an isosceles triangle are equal.

∴ <PQT = <TPQ = 40°

Now, consider ΔPQT

<QTP + <TPQ + <PQT = 180° (Sum of angles in a triangle)

<QTP + 40° + 40° = 180°

<QTP + 80° = 180°

<QTP = 180° - 80°

<QTP = 100°

Also, in the diagram, <QTP and <STR are vertically opposite angles

NOTE: Vertically opposite angles are equal

That is, <QTP = <STR

∴ <STR = 100°

Hence, the measure of arc SR is 100°. The correct option is the third option 100°
