Answer:

f(1) = 15

f(n) = f(n-1) x n

Step-by-step explanation:

The sequence in recursive form is:

f(1) = 15

f(n) = f(n-1) x n

Using this recursive formula, we can find the value of any term in the sequence by calculating the value of the previous term and multiplying it by the index of the current term.

For example, to find the value of f(2), we would use the formula:

f(2) = f(1) x 2

f(2) = 15 x 2

f(2) = 30

Similarly, to find the value of f(3), we would use the formula:

f(3) = f(2) x 3

f(3) = 30 x 3

f(3) = 90

And to find the value of f(4), we would use the formula:

f(4) = f(3) x 4

f(4) = 90 x 4

f(4) = 360

We can continue using this formula to find the values of any term in the sequence.

(a) Volume of the solid generated by revolving the region bounded by the graph is 12.422 cubic units.

(b)

(i) The work done in stretching the spring from its natural length to a length of 10 in. is 54 lb.-in.

(ii) The work done in stretching the spring from a length of 7 in. to a length of 9 in. is approximately 13.5 lb.-in.

(a) To find the volume of the solid generated by revolving the region bounded by the graph[tex]x^2=y-2[/tex] and 2y-x-2=0 for 0≤x≤1 about y=3, we can use the method of cylindrical shells:

First, we need to find the limits of integration for the radius of the shells. Since we are revolving around y=3, the distance between y=3 and the curve x^2=y-2 will give us the radius of the shell.

Solving for y in [tex]x^2=y-2[/tex], we get[tex]y=x^2+2.[/tex] Substituting this into 2y-x-2=0, we get [tex]x=2y-2y^2-2.[/tex] So the limits of integration for the radius will be from [tex]3-(x^2+2) to 3-(2y-2y^2-2).[/tex]

Next, we need to find the height of the shells. This is simply the length of the interval of integration for x, which is 0 to 1.

So the volume of the solid is given by the integral:

[tex]V = \int (3-(x^2+2)) - (3-(2y-2y^2-2)) dx[/tex] from x=0 to x=1

Simplifying and evaluating the integral, we get:

V ≈ 12.422 cubic units.

Therefore, the volume of the solid generated by revolving the region bounded by the graph [tex]x^2=y-2[/tex] and [tex]2y-x-2=0[/tex] for 0≤x≤1 about y=3 is approximately 12.422 cubic units.

(b) (i) The work done in stretching the spring from its natural length of 6 in. to a length of 10 in. can be found using the formula:

W =[tex](1/2)k(d2^2 - d1^2)[/tex]

where k is the spring constant, d1 is the initial length, and d2 is the final length.

Given that the force required to stretch the spring from its natural length of 6 in. to a length of 8 in. is 9 lb., we can find the spring constant as follows:

k = F/(d2 - d1) = 9/(8-6) = 4.5 lb/in

So the work done in stretching the spring from its natural length of 6 in. to a length of 10 in. is:

W = [tex](1/2)(4.5)(10^2 - 6^2)[/tex]= 54 lb.-in.

Therefore, the work done in stretching the spring from its natural length to a length of 10 in. is 54 lb.-in.

(ii) To find the work done in stretching the spring from a length of 7 in. to a length of 9 in., we can use the same formula:

W =[tex](1/2)k(d2^2 - d1^2)[/tex]

Using the same spring constant of 4.5 lb/in, the work done is:

W = [tex](1/2)(4.5)(9^2 - 7^2)[/tex]≈ 13.5 lb.-in.

Therefore, the work done in stretching the spring from a length of 7 in. to a length of 9 in. is approximately 13.5 lb.-in.

A cone is a three-dimensional geometric form with a plane base and a smooth tapering vertex. A cone is made up of a collection of line segments, half-lines, its  lines that connect the apex of the common point at to every point on a base that is in a flat  other than the apex. 

A measurement of three-dimensional space is volume. It is frequently expressed quantitatively using  US-standard units ,SI-derived units, as well as several imperial  Volume and the notion of length are connected.

Let the new radius x and the old radius as r. The formed volume was 175 cubic cm, and the new container height is 5 cm,

V = [tex]\frac{1}{3}\pi r^2h[/tex], where V is the volume, r is the radius, and h is the height, is the formula for a cone volume.

We can construct an equation using the previous volume:

175 =    [tex]\frac{1}{3}\pi r^2h[/tex]

the height is same for new and old container , so,:

175 =[tex]\frac{1}{3}\pi r^2*5[/tex]

175 = [tex]\frac{5}{3}\pi r^2[/tex]

By multiplying both sides by (5/3)

[tex]r^2 = \frac{175*3}{5*\pi}[/tex] ≈ 22.3 use [tex]\pi[/tex]=3.14

Therefore, the old container  radius is 4.72 cm.

now,We subtract the old radius from the new radius for  determine how much the radius must increase to s the new container:

x - r ≈ 4 - 4.72 ≈ -0.72

We can say with 95% confidence that the population variance σ2 lies within the interval [155.25, 570.06].

To construct a 95% confidence interval for the population variance σ2, we can use the chi-square distribution.

First, we need to calculate the chi-square values for the upper and lower limits of the confidence interval. We use the formula:

chi-square upper = (n-1)*s^2 / χ^2(α/2, n-1)

chi-square lower = (n-1)*s^2 / χ^2(1-α/2, n-1)

where n is the sample size, s is the sample standard deviation, α is the level of significance (0.05 for 95% confidence interval), and χ^2 is the chi-square distribution function.

Plugging in the values, we get:

chi-square upper = (25-1)*14^2 / χ^2(0.025, 24) = 43.98

chi-square lower = (25-1)*14^2 / χ^2(0.975, 24) = 15.14

Next, we can use these chi-square values to calculate the confidence interval for σ2:

confidence interval = [(n-1)*s^2 / chi-square upper, (n-1)*s^2 / chi-square lower]

Plugging in the values, we get:

confidence interval = [(25-1)*14^2 / 43.98, (25-1)*14^2 / 15.14]

Answer:

  51.2 inches

Step-by-step explanation:

You want the length of a mural whose hypotenuse is 96 inches if the scale drawing has a length of 8 inches and a hypotenuse of 15 inches.

The ratios of corresponding lengths will be the same:

  drawing length / drawing hypotenuse = mural length / mural hypotenuse

  8 in / 15 in = mural length / 96 in

Multiplying the equation by 96 in, we have ...

  (96 in)·8/15 = mural length

  51.2 in = mural length

The mural is 51.2 inches long.

The double integral of x² 2y over the given region (bounded by y = x, y = x³, and x > 0) is 2/35.

To solve this double integral, we need to integrate the function x² 2y over the given region in the xy-plane.

The region is bounded by the curves y = x and y = x³, and the line x = 0.

First, we need to determine the limits of integration. Since x > 0,

we can integrate from x = 0 to x = 1.

For each value of x in this range, the lower bound of y is given by y = x, and the upper bound is given by y = x³.

Therefore, we need to integrate with respect to y from y = x to y = x³ for each value of x in the range [0, 1].

So, the double integral can be written as:

∫(0 to 1) ∫(x to x³) x² 2y dy dx

Integrating with respect to y first, we get:

Therefore, the double integral of x² 2y over the given region is 2/35.

Answer:

The common difference is 2.

Answer:

The common difference of the arithmetic sequence 14, 16, 18 is **2**.

In any arithmetic sequence, each term is equal to the previous term plus the common difference. So, the second term is equal to the first term plus the common difference. In this case, the second term, 16, is 2 more than the first term, 14. Therefore, the common difference is 2.

We can also find the common difference by subtracting any two consecutive terms in the sequence. For example, we can subtract the second term from the third term to get 18 - 16 = 2.

The common difference of an arithmetic sequence is always constant. This means that the difference between any two consecutive terms in the sequence will always be the same. In this case, the difference between any two consecutive terms is 2.

The measure of arc FE is 27degrees,angle m<B is 112degrees, <GHJ = <GIJ = 73⁰ , m<S = 90 degrees in the given circles

The sum of angle in the triangle DEF is 180 degrees

mFE = <D

Recall that <D+<E+<F = 180⁰

<D+63+90 = 180

<D = 180-153

<D = 27 degrees

Hence the measure of arc FE is 27degrees

6) For this circle geometry, we will use the theorem

The sum of Opposite side of a cyclic quadrilateral is 180 degrees.

A + C = 180

m<A + 101 = 180

m<A = 180-101

m<A = 79degrees

Similarly

B + D = 180

m<B + 68 = 180

m<B = 180-68

m<B = 112degrees

7) The sum of angle in a circle is 360, hence;

arcGJ+68+31+115 = 36p

arcGJ = 360 - 214

arcGJ = 146⁰

Since the angle at the centre is twice angle at the circumference, then;

<GHJ = 1/2 arcGJ

<GHJ = 1/2(146)

<GHJ = 73⁰

<GHJ = <GIJ = 73⁰ (angle in the same segment of the circle are equal)

8) Recall that the sum of Opposite side of a cyclic quadrilateral is 180 degrees.

P + R = 180

57 + <R = 180

m<R = 180-57

m<R = 123degrees

Similarly, m<Q+m<S = 180⁰

Since the triangle in a semi circle is a right angled triangle, hence m<Q = 90 degrees (triangle PQR is a right angled triangle)

m<S = 180 - 90

Let c be the number of child tickets sold, and let a be the number of adult tickets sold.

We know that the price of a child ticket is $5.60, and the price of an adult ticket is $9.40.

From the problem statement, we know that 177 tickets were sold in total, so:

c + a = 177

We also know that the total revenue from ticket sales was $1352.20, so:

5.60c + 9.40a = 1352.20

Now we have a system of two equations with two variables. We can solve for a by using the first equation to express c in terms of a, and then substituting into the second equation:

c + a = 177 --> c = 177 - a

5.60c + 9.40a = 1352.20

Substituting c = 177 - a into the second equation, we get:

5.60(177 - a) + 9.40a = 1352.20

Expanding and simplifying:

992.20 - 5.60a + 9.40a = 1352.20

3.80a = 360

a = 95

The standard errors of the proportion for sample sizes of 40, 80, and 120 are 0.0733, 0.0518, and 0.0422, respectively,

How to calculate the standard error of the proportion?

To calculate the standard error of the proportion for a population with a proportion equal to 0.32 and sample sizes of 40, 80, and 120, we can use the formula:

Standard Error (SE) = √[(p * (1 - p)) / n]

where p is the proportion (0.32), and n is the sample size.

For a sample size of 40:
SE = √[(0.32 * (1 - 0.32)) / 40]
SE ≈ 0.0733 (rounded to 4 decimal places)

For a sample size of 80:
SE = √[(0.32 * (1 - 0.32)) / 80]
SE ≈ 0.0518 (rounded to 4 decimal places)

For a sample size of 120:
SE = √[(0.32 * (1 - 0.32)) / 120]
SE ≈ 0.0422 (rounded to 4 decimal places)

So, for a population with a proportion equal to 0.32, the standard errors of the proportion for sample sizes of 40, 80, and 120 are approximately 0.0733, 0.0518, and 0.0422, respectively, when rounded to 4 decimal places.

y = -5*( x² + 12x) - 176

y = -5*( x² + 2*6x) - 176

Now we can add and subtract 6² = 36 then we will get:

y = -5*( x² + 2*6x + 36 - 36) - 176

y = -5*( (x + 6)² - 36) - 176

y = -5(x + 6)² - 356

Which means that the vertex is at (-6, -356)
