For this problem, type your answers directly into the provided text box. You may use the equation editor if you wish, but it is not required. Consider the following series. 3 Σa_₁n³e-n² n=1 Part 1 (2 points). State whether the series converges or diverges. Part II (3 points). Justify your result in part I by using an appropriate test (basic divergence test, integral test, basic comparison test, or limit comparison test). Make sure to briefly state how you applied the test.
By using the basic comparison test and limit comparison test for the series: 3Σn=1 to ∞ a₁n³e⁻ⁿ², The number π²/2 is a finite number, and the series 3Σn=1 to ∞ a₁n³e⁻ⁿ² is convergent.
Part 1: We need to identify whether the given series is converging or diverging.
Part II: We can use the basic comparison test to test the convergence of the given series. Let's compare the given series with another series that is easily recognizable and convergent. For
n ≥ 1, a₁n³e⁻ⁿ² > 0
We know that the series Σ a₁n³e⁻ⁿ² is convergent, which means that the sequence of terms must be converging to zero as well. This can be shown using the following limit statement.
lim n→∞ a₁n³e⁻ⁿ² = 0.
By comparing the series with a simpler convergent series, we can prove that the series is convergent. The simpler convergent series can be represented by the expression 3Σn=1 to ∞ 1/n². This series is known as the p-series with p = 2. We can use this series to perform a comparison test.
Let Sn be the nth partial sum of the given series. Thus,
3Σn=1 to ∞ a₁n³e⁻ⁿ² ≤ 3Σn=1 to ∞ 1/n²
Let's evaluate the second series using the formula for the sum of a p-series:
Σn=1 to ∞ 1/n² = π²/6
Thus, 3Σn=1 to ∞ a₁n³e⁻ⁿ² ≤ 3 x π²/6

The given identities can be verified using basic rules of exponentials and algebra. Here are the steps to verify the given identities:
(a) 1 = ∑_(n=1) ^∞▒〖10^(x)+2(-1) ^nln(x)〗0
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n. ∑_(n=1)^∞▒10^(x) = 10^x+10^x+...= (2/3) (10^x) (odd terms only)∑_(n=1)^∞▒〖(-1)^nln(x)〗= ln(x)-ln(x)+ln(x)-ln(x)+...= (0) (even terms only)
Thus, we have 1= (2/3) (10^x) + (0) = (2/3) (10^x) (b) e^x = ∑_(n=1) ^∞▒〖10^x+2n(x)〗
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.
∑_(n=1) ^∞▒10^(x) = 10^x+10^x+...= (1/2) (10^x) (even terms only) ∑_(n=1) ^∞▒〖2n(x)〗= 2(x)+2(2x) +2(3x) +...= 2x (1+2+3+...) = -x/(-1) ^2= -x
Thus, we have e^x= (1/2) (10^x) - x(c) e^(-x) = ∑_(n=1) ^∞▒〖10^x+2(-1) ^nln(x)〗0
We can use the same series from part (a) with x replaced by -x.
Thus, we have e^(-x) = (2/3) (10^(-x)) + (0) = (2/3) (1/10^x)
Similarly, e^x= (2/3) (10^x) Subtracting these two equations, we get: e^x - e^(-x) = (2/3) (10^x + 1/10^x) (answer) (d)
Cosh x = ∑_(n=0) ^∞▒〖10^x+2n(x)〗
Similar to part (b), we have two series, one for even values of n, and one for odd values of n.∑_(n=0)^∞▒10^(x) = 1+10^x+10^x+...= (1/2) (10^x) (even terms only)∑_(n=0)^∞▒〖2n(x)〗= 0+2x+2(2x)+2(3x)+...= 2x (1+2+3+...)= 2x(1/(-1)^2)= 2xThus, we have Cosh(x) = 1 + (1/2) (10^x) + 2x (e^x)(e^x - e^(-x)) / 2= 1 + (1/2) (10^x) + 2x (1 + (2/3) (10^x + 1/10^x)) (answer)(e) Sinh x = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗
Rewrite the sum to obtain two series, one for even values of n, and one for odd values of n.∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x+2^3x+2^5x+...= 2x(1+2^2+2^4+...)= 2x(2^0+2^2+2^4+...)= 2x(1/ (1-2^2))= -2x/3Thus, we have Sinh(x) = ∑_(n=1)^∞▒〖2^(2n-1)(x)〗= 2x/3 (answer)

Consider the function y x2-3x + 2. At what value of x is the slope of the tangent line equal to 5 Select one: 0 a,-4 O b. 4 O c. 2
The value of x at which the slope of the tangent line to the given function is equal to 5 is 4. Thus, the correct answer is option (b).
The incline of the digression line to the capability y=x²-3x+2 at some random point (x₀, y₀) on the bend is given by the subordinate of the capability by then. To find the worth of x for which the slant of the digression line is equivalent to 5, we want to separate the given capability and set it equivalent to 5 and afterward tackle for x.
Therefore, let's distinguish the function from x: dy/dx = 2x - 3 Now, we need to set this derivative to 5: 2x - 3 = 5. If we solve for x, we get: 2x = 8x = 4. This means that the value of x at which the tangent line to the given function is equal to 5 is 4. Accordingly, the right response is choice (b).

True/False: if the probably of committing a type ii error is 0.20, then the computed value for power is 0.80.
False. Type II error and power are complementary probabilities. The power of a statistical test is the probability of rejecting the null hypothesis when it is false (i.e., correctly detecting a significant effect or difference).
On the other hand, the type II error is the probability of failing to reject the null hypothesis when it is false (i.e., failing to detect a significant effect or difference).
Therefore, if the probability of committing a type II error is 0.20, then the power of the test is 1 - 0.20 = 0.80. This means that there is an 80% chance of correctly detecting a significant effect or difference.
However, we cannot determine the power of a statistical test from the probability of committing a type II error alone. We would need additional information such as the sample size, effect size, alpha level, and variability to calculate the power of the test.

Determine whether the given differential equation is exact. If it is exact, solve it. (If it is not exact, enter NOT.) dy/ dx = 9xe^x – y + 6x2
The given differential equation is not exact. To determine if a differential equation is exact, we need to check if its partial derivatives satisfy a specific condition.
In this case, the given equation is dy/dx = 9xe^x – y + 6x^2. Let's find the partial derivatives of the expression on the right-hand side with respect to y and x.∂/∂y (9xe^x – y + 6x^2) = -1∂/∂x (9xe^x – y + 6x^2) = 9e^x + 12x
The condition for exactness is that these partial derivatives are equal: ∂/∂y (∂/∂x) = ∂/∂x (∂/∂y). However, in this case, we have -1 ≠ 9e^x + 12x, which means the equation is not exact.As the equation is not exact, we cannot directly solve it by finding a potential function. Other methods, such as using integrating factors or applying specific techniques for solving non-exact equations, may be required.

In Canada, the rate of inflation (i.E. How much things cost) is about 2.0%/year. In other words, the real value of your money is worth 2.0% less each year. Imagine you have $2250 in savings under your mattress
Answer:
Step-by-step explanation:
If you have $2250 as against an inflation rate of 2% every year, this then means that after the first year, the value of your money becomes

What is Fundamental Theοrem οf Calculus?Tο find the value οf f(6), we can use the Fundamental Theοrem οf Calculus. Accοrding tο the theοrem, if f(x) is cοntinuοus οn an interval [a, b] and F(x) is an antiderivative οf f(x) οn that interval, then the definite integral οf f(x) frοm a tο b is equal tο F(b) - F(a).
Given that f'(x) is cοntinuοus, we can apply the theοrem tο the integral:
∫₅₆ f'(x) dx = f(6) - f(5)
We are given that ∫₅₆ f'(x) dx = 19, and f(5) = 11. Plugging in these values, we have:
19 = f(6) - 11
Tο sοlve fοr f(6), we add 11 tο bοth sides:

ODE solutions using Laplace transforms
Solve the following initial value problem using Laplace transforms:
y" - 2y = e^x, y(0) = 0, y'(0) = 0.
The solution of the given differential equation using the Laplace transform is y(t) = 1 − [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].
Given differential equation is y″−2y = eˣ, y(0) = 0, y′(0) = 0. We will solve it using Laplace transforms.
To solve the given differential equation using the Laplace transform, take the Laplace transform of each term of the differential equation. Then solve for Y(s) and find y(t) by taking the inverse Laplace transform.
Here, we take L{y} for Y(s) and L{y''} and L{y'} for s²Y(s) and sY(s) respectively.
L[y′′] − 2L[y] = L[eˣ] s²Y(s) − s⋅y(0) − y′(0) − 2Y(s)
= 1s − 1.0 − 0 − 2Y(s)
= 1s − 1
We have to rearrange the terms of the above equation in order to get Y(s) on one side.
Y(s) = 1s(s−2)(s−1) = As+Bs−2+Cs−1.
Using partial fraction expansion, A=1, B=1, and C=−2.
So,Y(s) = 1s+(1s−2)−2s−1.
We can write Y(s) as follows.Y(s) = 1s−(1s−2)+2s−1.
Then find the inverse Laplace transform of Y(s) to get the solution y(t).
y(t) = L − 1{Y(s)} = L − 1{1s} − L − 1{1s−2} + L − 1{2s−1}
= 1 − [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].
Therefore, the solution of the given differential equation using Laplace transform is y(t) = 1 − [tex]e^{2t}[/tex] + 2 [tex]e^{-t}[/tex].
