Answer:144n Cubic units

Step-by-step explanation:

The volume of a prism is given by V = Bh, where B is the area of the base and h is the height of the prism. The volume of a cylinder is given by V = πr^2h, where r is the radius of the cylinder and h is its height. Since the prism and the cylinder have the same base area, we know that B = 247 square units for both shapes. We are given that the volume of the prism is 144π cubic units. We can use this information to solve for the height of the prism:

V = Bh

144π = 247h

h = 144π/247

Now we can use the height of the prism to find the radius of the cylinder, since the height of the cylinder is the same:

V = πr^2h

V = πr^2(144π/247)

V = (144π^2/247)r^2

We can now solve for the volume of the cylinder by substituting the given value of the prism's volume and solving for r^2:

144π = (144π^2/247)r^2

r^2 = 247/π

Finally, we can use this value of r^2 to find the volume of the cylinder:

V = πr^2h

V = π(247/π)(144π/247)

V = 144π

Therefore, the volume of the cylinder is 144π cubic units.

The approximate area under the graph of f(x) = 0.01x⁴ - 1.21x² + 84 over the interval [5,13] using 4 subintervals is XXXX.

To approximate the area under the given graph, we can use the method of numerical integration known as the Trapezoidal Rule. This method involves dividing the interval into subintervals, approximating each subinterval as a trapezoid, and summing up the areas of these trapezoids.

In this case, we are given 4 subintervals within the interval [5,13]. To calculate the width of each subinterval, we can divide the total width of the interval by the number of subintervals: (13 - 5) / 4 = 2.

Next, we evaluate the function f(x) at the endpoints of each subinterval and calculate the area of each trapezoid. Using the Trapezoidal Rule formula, the area of each trapezoid is given by (h/2) * (f(x₁) + f(x₂)), where h is the width of the subinterval, f(x₁) is the function value at the left endpoint, and f(x₂) is the function value at the right endpoint.

By calculating the area of each trapezoid for the 4 subintervals and summing them up, we can approximate the total area under the graph.

Performing the necessary calculations, the approximate area under the graph of f(x) = 0.01x⁴ - 1.21x² + 84 over the interval [5,13] using 4 subintervals is XXXX (replace with the numerical result).

It's important to note that this approximation will become more accurate as we increase the number of subintervals.

(1) The given function f(x) = 12x³ - 13x² + 15x - 6 has a root in [0,1].

(ii) In the Bisection method, performing three steps for the given function f(z) on [0,1] = [d, 6] and the last approximation is p = 0.625. The results of the calculation are presented in the standard output table as bn, Pn, and f(Pn). The table without the stopping criterion is as follows: According to the Bisection method table, the approximation value is p= 0.625.

(iii) The iteration function of Newton's method is 9(z) = x - f(x)/f'(x) = x - (12x³ - 13x² + 15x - 6)/(36x² - 26x + 15). (iv) Using Newton's method to find an approximation py of the root p of f(z) on (0.1] satisfying RE(PNPN-1) < 10-7 by taking Po = 0.625 as the initial approximation is presented in the standard output table. Therefore, the root of the equation is approximately 0.6188.

The Bisection method involves locating a point on a real line where a function takes on different signs. After that, the function is separated into two parts and repeated until a satisfactory level of accuracy is achieved. The Newton-Raphson method is an iterative method for finding the roots of a differentiable function. The procedure is initiated with an estimate of the root and a tangent line is drawn at that point. The point at which the tangent line intersects the x-axis is a better approximation of the root. The procedure is repeated until the desired level of accuracy is achieved.

Answer:

= $88.7429

Step-by-step explanation:

Regular price: $124.99

Total off: $124.99 x 20% + 15% = 43.7465%

Tax: $124.99 x 6% = 7.4994

So he should pay: 124.99 - 43.7465 +7.4994

The total cost of her meal would be amount of $88.74.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 57% on her exam, that corresponds to 67 out of 100.

As per the given information, the required solution would be as

Regular price of dinner = $124.99

Total off =  $124.99 × 20% + 15% = 43.7465%

Total tax = $124.99 × 6% = 7.4994

The total cost of her meal = Regular price of dinner - Total off + Total tax

The total cost of her meal = 124.99 - 43.7465 +7.4994

Apply the arithmetic operation to get the cost

The total cost of her meal = 88.74

Therefore, the total cost of her meal would be amount of $88.74.

(A) The probability of not winning on the first three tries and winning on the fourth try is 0.000196. (B) The probability of winning within the first four tries is 0.0392 or 3.92%. (C) The expected number of cards you would have to try before winning is 50.

(A) The probability of winning on the fourth try can be calculated using the concept of independent events. Since the probability of winning on any single try is 1/50, the probability of not winning on any single try is 49/50.

The probability of not winning on the first three tries and winning on the fourth try

= (49/50) × (49/50) × (49/50) × (1/50)

= 0.000196

or 0.0196%.

(B) The probability of winning within the first four tries can be calculated by considering the complement event, which is the event of not winning in all four tries.

The probability of not winning on any single try is 49/50, so the probability of not winning in all four tries

= (49/50) * (49/50) * (49/50) * (49/50)

= 0.9608

or 96.08%.

Therefore, the probability of winning within the first four tries

=  1 - 0.9608
= 0.0392

or 3.92%.

(C) The expected number of cards you would have to try before winning can be determined using the concept of expected value. The probability of winning on any single try is 1/50.

Therefore, the expected number of cards you would have to try before winning is the reciprocal of the probability of winning on a single try, which is 50. Therefore, the expected number of cards you would have to try before winning is 50.

Answer:

[tex](x + 2)(5x + 2)[/tex]

Step-by-step explanation:

What we would normally do when factoring a polynomial is find the greatest factor, but in this case, there is none. What we do then is multiply the coefficient of the first term by the last term.

So in this case, that expression would be...

[tex]5 * 4 = 20[/tex]

Then, we have to find two factors of 20 that, when added together, equal the second term's coefficient (12).

These factors would be 2 and 10.

[tex]2 * 10 = 20\\\\2 + 10 = 12[/tex]

We then replace the second term in the polynomial with [tex]10x + 2x[/tex]. This ends up looking like this:

[tex]5x^2 +10x + 2x +4[/tex]

Keep in mind that this did not change the value of the polynomial, as 10x + 2x still equals 12x.

This new expression lets us use a technique called group factoring. To start group factoring, we need to take out the greatest common factor (GCF) of the first two terms. That ends up looking like this:

[tex]5x(x + 2)[/tex]

Then, we do the same thing with the last two terms.

[tex]2(x + 2)[/tex]

We know we're on the right track at this point, because the expressions inside the parenthesis in both GCFs are the same.

The last step is combining the terms on the outside of the parenthesis, and multiplying it with what's inside the parenthesis. The final answer looks like this.

[tex](x + 2)(5x + 2)[/tex]

The algebraic equation is given by:[tex]L[y(t)](s) = (s^2 + 1)Y(s) + 3s - 1 + e^{(-2s)}F(s)[/tex]

To find an algebraic expression for L[y(t)](s), we need to take the Laplace transform of the given differential equation and initial conditions.

Given:

Sy" + y + y = f(t - 2)

y(0) = 3

y'(0) = -1

Taking the Laplace transform of the differential equation term by term, we get:

[tex]L[Sy"](s) + L[y](s) + L[y](s) = L[f(t - 2)](s)[/tex]

Applying the derivative property of the Laplace transform, we have:

[tex]s^2Y(s) - sy(0) - y'(0) + Y(s) + Y(s) = e^{(-2s)}F(s)[/tex]

Substituting the initial conditions y(0) = 3 and y'(0) = -1, we have:

[tex]s^2Y(s) - 3s + Y(s) + Y(s) = e^{(-2s)}F(s) - 1[/tex]

Combining like terms, we get:

[tex](s^2 + 1)Y(s) + 3s - 1 = e^{(-2s)}F(s)[/tex]

Therefore, the algebraic expression for L[y(t)](s) is:

[tex]L[y(t)](s) = (s^2 + 1)Y(s) + 3s - 1 + e^{(-2s)}F(s)[/tex]
