give the mclaurin series for f ( x ) = cos ( x 2 ) .

Answers

Answer 1
Sure, I can help you with that.

The Maclaurin series for f(x) = cos(x^2) is:

f(x) = 1 - x^4/2! + x^8/4! - x^12/6! + ...

This can be derived from the Maclaurin series of cos(x) using the chain rule and the fact that the derivative of x^2 is 2x.

Consider the following series. 7n + 18-n n = 1 Determine whether the geometric series is convergent or divergent. Justify your answer. • Converges; the series is a constant multiple of a geometric series. Converges; the limit of the terms, ap, is 0 as n goes to infinity. O Diverges; the limit of the terms, an, is not 0 as n goes to infinity. O Diverges; the series is a constant multiple of the harmonic series. If it is convergent, find the sum. (If the quantity diverges, enter DIVERGES.)

Answers

Diverges. Series is not a geometric series as it does not have a common ratio. However, we can rewrite the series as:
7n + 18-n = 7n(1 + 18(-1/n))
As n approaches infinity, the second term inside the parentheses approaches 1, so we can write:
7n(1 + 18(-1/n)) ≈ 7n(1 + 0) = 7n
Thus, we can see that the series is a constant multiple of the series 7n, which is a geometric series with a common ratio of 7. Since the common ratio is greater than 1, the series diverges.

To determine if the series is convergent or divergent, we should  find the limit of the terms as n goes to infinity.
The series can be rewritten as: (7n) + (18(-n)n)

As n goes to infinity, the term 7n will also go to infinity. Meanwhile, the term 18(-n)n will approach 0 since any number

raised to a negative power becomes smaller as n increases. However, the 7n term dominates the series, so the limit of

the terms is not 0 as n goes to infinity.
Therefore, the series is divergent.  Diverges; the limit of the terms, an, is not 0 as n goes to infinity.

Simplify: 2 4/5-1 2/5

Answers

Answer:

Step-by-step explanation:

24/5-12/5=12/5

To simplify 2 4/5 - 1 2/5, we first need to convert the mixed numbers into improper fractions.

Step 1: Convert the mixed numbers to improper fractions:

2 4/5 = (2 x 5 + 4)/5 = 14/5

1 2/5 = (1 x 5 + 2)/5 = 7/5

Step 2: Subtract the two improper fractions:

14/5 - 7/5 = (14 - 7)/5 = 7/5

Step 3: Convert the resulting fraction back into a mixed number, if necessary:

7/5 can be written as 1 2/5

Therefore, 2 4/5 - 1 2/5 = 1 2/5

The behavior of the integral of [tex]2e^(-x)[/tex] dx, given by the function [tex]-2e^(-x) + C[/tex], shows an exponential decay.

To algebraically determine the behavior of the integral of [tex]2e^(-x) dx[/tex], we need to perform the integration and observe the resulting function.

Step 1: Integrate the function with respect to x:
We want to find the integral ∫[tex]2e^(-x) dx[/tex]. To do this, we apply the integration rule ∫[tex]e^(ax) dx = (1/a)e^(ax) + C[/tex], where a is a constant and C is the integration constant.

In our case, a = -1. So, the integral becomes:
∫[tex]2e^(-x) dx = (1/-1) * 2e^(-x) + C = -2e^(-x) + C[/tex]

Step 2: Analyze the behavior of the function:
Now that we have the integral, we can observe its behavior. The resulting function is [tex]-2e^(-x) + C[/tex], which is an exponential decay function with a negative coefficient. As x approaches positive infinity, [tex]e^(-x)[/tex] approaches 0, making the function approach the constant value C. Similarly, as x approaches negative infinity, [tex]e^(-x)[/tex] approaches infinity, making the function approach negative infinity.

In summary, the behavior of the integral of [tex]2e^(-x)[/tex] dx, given by the function [tex]-2e^(-x) + C[/tex], shows an exponential decay. As x increases, the function approaches a constant value, while as x decreases, the function approaches negative infinity.

There are M green and N red apples in the box. We start removing randomly one apple at a time from the box until we remove all the green apples. What is the probability that there is no apple left in the box after that? What is the probability that there are exactly k apples left after that?

Answers

Based on probability, the response to the question is,

[tex]a).\ (\frac{N}{(M+N)} )^M\\\\b).\ C(N+k-1,k)^*((\frac{M}{M+N} )^M)^*((\frac{(N+k-1)}{(M+N)} )^k)[/tex]

What is Probability?

Probability measures the likelihood or probability of an event happening. It is a number between 0 and 1, where 0 signifies an unlikely occurrence (one that would never happen) and 1 denotes an expected event (one that would happen frequently). Events between 0 and 1 have probabilities between 0 and 1, and the closer an event's probability approaches 1, the more probable it is to occur.

After removing all of the green apples, there is a chance that there won't be an apple in the box [tex](\frac{N}{(M+N)} )^M[/tex].

This is so that there are always less apples overall and fewer green apples overall after each removal. On the first draw, there is a chance of removing a green apple of M / (M + N).

On the second draw, there is a chance of removing another green apple (M-1) / (M + N - 1) until all M green apples have been taken out. These probabilities can be combined to determine the likelihood that all M green apples are taken out of the box, leaving nothing inside.

The binomial coefficient indicates the likelihood that exactly k apples remain in the box after all the green apples have been removed,

[tex]C(N+k-1, k) * ((\frac{M}{(M+N)} )^M) * ((\frac{(N+k-1)}{(M+N)} )^k)[/tex]

This is due to the fact that C(N+k-1, k) methods for choosing which of the remaining (N+k-1) apples are red, and the likelihood that this

choice will be made is [tex](\frac{(N+k-1)}{(M+N)} )^k*((\frac{M}{(M+N)} )^M)[/tex].

Let the total number of participants be P. Then, the number of children is (P-125), and the number of girls is (P-125) × (1-B/(P-125)), where B is the number of boys, put all values:

(P-125) × (1-B/(P-125)) = (P-B-125)/2

Simplifying the above equation, we get:

B² - 250B + (P-125)² = 0

We know the quadratic formula;

B = (250 ± √(250² - 4×(P-125)²))/2

Since B must be an integer, only the positive root is possible, and it must be a whole number.
Therefore, we can solve for P by trying out integer values for B until we find one that gives a whole number for P. Trying out values, we find that B = 100 gives P = 200, which is a whole number.

find the first four terms of the taylor series for the function 3/x about the point α = 2 . (your answers should include the variable x when appropriate.

Answers

The first four terms of the Taylor series for 3/x about the point α = 2 are: 3/2 - (3/4)(x-2) + (3/4)(x-2)² - (9/16)(x-2)³.

To find the Taylor series for a function, we need to calculate its derivatives at the point of expansion and then substitute those values into the general formula for the Taylor series. The general formula for the Taylor series of a function f(x) about a point a is:

f(x) = f(a) + f'(a)(x-a)/1! + f''(a)(x-a)²/2! + f'''(a)(x-a)³/3! + ...

Here, we want to find the Taylor series for the function f(x) = 3/x about the point α = 2. First, we will calculate the derivatives of f(x):

f(x) = 3/x

f'(x) = -3/x²

f''(x) = 6/x³

f'''(x) = -18/x⁴

Now we can substitute these derivatives into the general formula for the Taylor series to get:

f(x) = f(2) + f'(2)(x-2)/1! + f''(2)(x-2)²/2! + f'''(2)(x-2)³/3! + ...

We can calculate the first few terms of this series:

f(2) = 3/2

f'(2) = -3/4

f''(2) = 3/4

f'''(2) = -9/16

Substituting these values into the series, we get:

3/x = 3/2 - (3/4)(x-2) + (3/4)(x-2)² - (9/16)(x-2)³ + ...

So the first four terms of the Taylor series for 3/x about the point α = 2 are 3/x = 3/2 - (3/4)(x-2) + (3/4)(x-2)² - (9/16)(x-2)³

(Give the smallest integer value of n for which this is true.] 6

Answers

To find the smallest value of n for which the sum of the series is accurate to within 0.00001, we need to use the formula for the remainder of a convergent series:

R_n = |S - S_n|

where R_n is the remainder, S is the sum of the series, and S_n is the sum of the first n terms.

We want R_n to be less than or equal to 0.00001, so we have:

|R_n| ≤ 0.00001

Substituting the given values, we get:

|(2n+1)^4/5 - 51| ≤ 0.00001

Simplifying and taking the fifth root, we get:

2n+1 ≤ (51.00001)^(1/4)

2n+1 ≤ 3.1673

n ≤ 1.5836

Since n has to be an integer, the smallest value of n that satisfies this inequality is n = 1.

Therefore, we need at least 1 term of the series to get a sum accurate to within 0.00001.

Note: This is a bit of a tricky question because the given series converges very quickly, so only one term is needed to get a sum accurate to within 0.00001.
To determine how many terms of the series are needed so that the sum is accurate to within 0.00001, we can use the remainder estimation theorem.

Given the desired remainder, 0.00001, and the error tolerance, 0.0005, we can find the smallest integer value of n that satisfies these conditions. Since the series is a convergent alternating series, the remainder is less than the absolute value of the (n+1)th term. Therefore, we need to find the smallest integer value of n for which:

|(2n + 1)^(-4)/51| < 0.00001

Solving for n, we can determine the smallest value that meets this criterion. By trial and error or using a calculator, we can find that the smallest integer value of n that satisfies this condition is n = 6.

Answers

The temperature ratio T2/T1 = I^(γ-1), and for small disturbances, the change in entropy ΔS ≈ n * R * 2 * (γ - 1) * ε.

The temperature ratio T2/T1 in terms of the pressure ratio P2/P1 can be found using the adiabatic process equation for an ideal gas. For an adiabatic process, the equation is:

P1 * V1^γ = P2 * V2^γ

Where γ is the heat capacity ratio (Cp/Cv). Since P2/P1 = I, we can rewrite the equation as:

V1^γ = V2^γ * I

From the ideal gas law, we know that P1 * V1 / T1 = P2 * V2 / T2, so:

V1 / T1 = V2 / T2 * I

Now, we can substitute V1^γ from the first equation into the second equation:

T2 / T1 = I^(γ-1)

For the change in entropy, we can use the formula:

ΔS = n * Cv * ln(T2 / T1) + n * R * ln(V2 / V1)

Substituting the temperature ratio and the volume ratio, we get:

ΔS = n * R * [(γ - 1) * ln(I) + ln(I^(γ - 1))]

For small disturbances, where I = 1 + ε and ε << 1, we can use the approximation ln(1 + ε) ≈ ε:

ΔS ≈ n * R * (γ - 1) * ε + n * R * (γ - 1) * ε

ΔS ≈ n * R * 2 * (γ - 1) * ε

A. x=-3
B. x=3
C. x=10
D. x=-6

Answers

Answer:

B. x = 3

--------------------

Given equation:

    [tex]x+1=\sqrt{19-x}[/tex]

Square both sides, considering 19 - x ≥ 0  ⇒ x ≤ 19:

(x + 1)² = 19 - x

Solve the quadratic equation by factoring:

x² + 2x + 1 = 19 - xx² + 3x - 18 = 0x² + 6x - 3x - 18 = 0x(x + 6) - 3(x + 6) = 0(x - 3)(x + 6) = 0x - 3 = 0 and x + 6 = 0x = 3 and x = - 6

The matching choice is B.

17. sketch each angle. then find its reference angle. show your calculations. a. 13pi/8

Answers

The reference angle for 138 is 58.


Let's first sketch the angle and then find its reference angle using the terms you mentioned.

Step 1: Sketch the angle 13π/8
To sketch the angle, first, we need to determine its position on the coordinate plane. Since 13/8 is greater than  (or 8/8), it's located in the third quadrant. As a full circle is 2 (or 16/8), we can determine the angle measured counterclockwise from the positive x-axis as:
Angle = 13π/8

Step 2: Find the reference angle
A reference angle is an acute angle formed between the terminal side of the angle and the x-axis. In the third quadrant, the reference angle is calculated as:
Reference Angle = Angle - π

Now we substitute the values:
Reference Angle = 13π/8 - 8π/8 = 5π/8

So, the reference angle for 138 is 58.

Answers

The value of x that satisfies the given conditions is approximately 7.

Given that KLMN is similar to PQRS. This means that the corresponding sides of these two angles are proportional. We can use this property to set up a proportion between the sides of the two angles.

Let LM and RQ be corresponding sides in the two triangles, and let KN and SP be the other corresponding sides. Then we have:

LM/RQ = KN/SP

Substituting the given values, we get:

(4x + 4)/48 = (7x - 9)/60

To solve for x, we cross-multiply, which gives us:

(4x + 4) * 60 = (7x - 9) * 48

Expanding both sides, we get:

336x - 432 = 240x + 240

Simplifying and solving for x, we get:

96x = 672

x = 7

Therefore, the value of x that satisfies the given conditions is approximately 7.

What is the product of 50% of 30 and 25% of 40?​

Answers

Answer:

50% of 30 is 15. 25% of 40 is 10. So, the product of 50% of 30 and 25% of 40 is 150.

Here's the calculation:

```

(50/100) * 30 * (25/100) * 40 = 150

```

Step-by-step explanation:

6. An oil company wants to lay a pipeline from its offshore drilling rig to a storage tank on shore, as illustrated in the accompanying figure. The rig (point R) is 3 miles offshore (point A), and the storage tani (point B) is 8 miles down the shoreline. The cost of laying pipe underwater is $800 per mile and along the shoreline is $400 per mile. Point P is the point on shore where the underwater pipe connects with the shoreline pipe. Where should point P be located so as to minimize the cost of laying pipe? Show the function and domain you need to optimize. Provide a complete answer and state units. R (Oil rig) 3 mi Shoreline B (Storage tank) 8 mi

Answers

The units for the cost function C(x,y) are dollars, and the units for x and y are miles.

To minimize the cost of laying the pipeline:

Point P should be located 1.5 miles down the shoreline from the storage tank (point B).

To show this, let x represent the distance from point B to point P along the shoreline, and y represent the distance from point P to the rig (point R) underwater.

Then, the total cost of laying the pipeline can be represented by the function C(x,y) = 800y + 400(8-x).

Since the distance from point A to point R is 3 miles, we know that x + y = 3. Solving for y in terms of x, we get y = 3-x.

Substituting this into the cost function, we get C(x) = 800(3-x) + 400(8-x) = 3200 - 400x.

To minimize this function, we can take the derivative and set it equal to zero:

C'(x) = -400.

Therefore, there is no critical point, but the function is decreasing as x increases.

Since x represents the distance from point B to point P along the shoreline, we want to minimize x while still satisfying the constraint that x + y = 3.

This means that y must be maximized, which occurs when x = 1.5.

Therefore, point P should be located 1.5 miles down the shoreline from the storage tank (point B) and 1.5 miles from the rig (point R) underwater.

The domain of the function we optimized was x in [0,8] (the distance along the shoreline from point B to the right) since we cannot have a negative distance or a distance greater than 8 miles along the shoreline.

The units for the cost function C(x,y) are dollars, and the units for x and y are miles.
