a) True. If lim n → [infinity] an = 0, then by definition of convergence, for any ε > 0 there exists an N such that for all n > N, |an| < ε. Thus, an is convergent.

b) False. If sin(20) > 0, then the series diverges (by comparison to the harmonic series), and if sin(20) ≤ 0, then the series oscillates and does not converge.

c) True. If lim n→[infinity] an = L, then by definition of convergence, for any ε > 0 there exists an N such that for all n > N, |an - L| < ε/2. Thus, for all n > N, |a(2n+1) - L| ≤ |a(2n+1) - an| + |an - L| < ε/2 + ε/2 = ε, so lim n→[infinity] a(2n+1) = L.

d) True. If −1 < α < 1, then as n→[infinity], αn approaches 0 from above (if α > 0) or below (if α < 0), and since it is always positive, it must approach 0.

e) False. For example, if an = (-1)^n and bn = (-1)^(n+1), then both sequences diverge but their sum is identically 0.

Answer:

\(y=sin^{-1}x\)

Step-by-step explanation:

Given: A point is \((0,2\pi)\)

To find: function whose graph passes through the given point

Solution:

A trigonometry explains the relationship between the sides and the angles of the triangle.

The inverse trigonometric functions \(sin^{-1}x\,,\,cos^{-1}x\,,\,tan^{-1}x\) help to find the value of an unknown angle of a right triangle when length of two sides are given.

Consider \(\sin y=x\)

Put \(y=2\pi\)

\(sin 2\pi=0\)

So, point \((0,2\pi)\) satisfies the function \(y=sin^{-1}x\)

Therefore, graph of function \(y=sin^{-1}x\) passes through \((0,2\pi)\)

Answer:

Step-by-step explanation:

We need to find the slope first, and we'll use the formula rise/run.

6 - -9/ -3 - 5 =  15/-8.

Our slope is -15/8.

Now, we need to find the y-intercept, which is b.

y = mx+b.

m is the slope, so y=-15/8x+b

Now, let's replace x  with 5 from that point and replace y with -9 from that same point.

-9 = -(15/8)(5) + b

-72/8 = -75/8 + 3/8

So, the equation is y= -15/8x + 3/8

The decrease in diameter of the bar due to the applied load is -0.005434905d and the final diameter of the bar is 1.005434905d.

A compressive load of 80,000 lb is applied to a bar with a circular section of 0.75 in diameter and a length of 10 in.

if the modulus of elasticity of the bar material is 10,000 ksi and the Poisson's ratio is 0.3.

We have to determine the decrease in diameter of the bar due to the applied load.

Let d be the initial diameter of the bar and ∆d be the decrease in diameter of the bar due to the applied load, then the final diameter of the bar is d - ∆d.

Length of the bar, L = 10 in

Cross-sectional area of the bar, A = πd²/4 = π(0.75)²/4 = 0.4418 in²

Stress produced by the applied load,σ = P/A

= 80,000/0.4418

= 181163.5 psi

Young's modulus of elasticity, E = 10,000 ksi

Poisson's ratio, ν = 0.3

The longitudinal strain produced in the bar, ɛ = σ/E

= 181163.5/10,000,000

= 0.01811635

The lateral strain produced in the bar, υ = νɛ

= 0.3 × 0.01811635

= 0.005434905'

The decrease in diameter of the bar due to the applied load, ∆d/d = -υ

= -0.005434905∆d

= -0.005434905d

The final diameter of the bar,

d - ∆d = d + 0.005434905d

The value of z that should be used when making a 93% confidence interval for p is Z=1.81 that is option D.

The z score is a measure of how many standard deviations a raw score is below or above the population mean. It will be positive if the value is more than the mean and negative if it is less than the mean. It is often referred to as the standard score. It represents the number of standard deviations an entity has from the mean.

To utilise a z-score, both the mean and the population standard deviation must be known. The z score calculates the likelihood of a score occuring within a standard normal distribution. It also allows us to compare scores from various samples. A table for the values of, representing the values of the cumulative distribution function of the normal distribution, is known as a

At 93% confidence, the significance level is,

ɑ= 1-0.93

The critical point of the function z = x² + y² - 4xy + 2 is (0, 0). It is a local minimum since the discriminant is positive and the second partial derivative with respect to x is positive.

The given function is z = x² + y² - 4xy + 2. To find the critical points of the function, we need to find its partial derivatives with respect to x and y and equate them to zero. Then, we can solve the resulting system of equations to obtain the critical points.

The partial derivatives of the function with respect to x and y are ∂z/∂x = 2x - 4y and ∂z/∂y = 2y - 4x. Equating both partial derivatives to zero, we get x = 2y and y = 2x. Solving these two equations, we get x = y = 0, which is the only critical point of the function.  

To classify the critical point, we need to compute the second partial derivatives of the function with respect to x and y at (0, 0). The discriminant of the Hessian matrix is D = ∂²z/∂x² ∂²z/∂y² - (∂²z/∂x∂y)². Since the discriminant is positive and ∂²z/∂x² > 0, the critical point (0, 0) is a local minimum of the function.

Step-by-step explanation:

The statement " An interval estimate is a range of values within which the actual value of the population parameter, such as μ, may fall" is true.

An interval estimate is a range of values within which the actual value of the population parameter, such as μ, may fall with a certain degree of confidence. The interval estimate is based on sample data and statistical methods, and it provides a measure of the uncertainty associated with the estimate of the population parameter.

Interval estimates are important in statistics because it is often not possible to determine the true population parameter with absolute certainty. Instead, statistical inference provides us with a range of plausible values for the parameter based on the data that has been collected. This range of plausible values is called a confidence interval.

The strongest correlation is -0.4.

Option C is correct.

Correlation is a statistical term that expresses how closely two variables are related linearly (meaning they change together at a constant rate). It's a typical tool for describing simple relationships without stating a cause and effect link.

When the result is closer to +1 (positive correlation) or -1 (negative correlation), the strongest correlation is considered (negative correlation).

A positive correlation coefficient means that the value of one variable is directly related to the value of another.

Here -0.4 is the closest value to 1.

To solve the system of equations using the elimination method, we'll eliminate one variable by adding or subtracting the equations.

Let's go through the steps: Given equations: 2x + 4y = 10.  -2x + y = -15. To eliminate the variable 'x', we can add the two equations together: (2x + 4y) + (-2x + y) = 10 + (-15). Simplifying the equation: 2x - 2x + 4y + y = -5. Combining like terms: 5y = -5. Dividing both sides by 5: y = -1(Answer).  Now, substitute the value of 'y' back into one of the original equations to solve for 'x'. Let's use equation (2): -2x + (-1) = -15. Simplifying the equation: -2x - 1 = -15. Adding 1 to both sides: -2x = -15 + 1.  -2x = -14.  Dividing both sides by -2: x = 7(Answer).

Therefore, the solution to the system of equations is (x, y) = (7, -1). Looking at the answer choices, the correct option is B) (7, -1).

When dealing with the simultaneous occurrence of two events A and B, the probability can be determined by using the probability of one event and the conditional probability of the other event given that the first event has occurred. Both P(A) * P(B|A) and P(B) * P(A|B) are valid ways to calculate this probability.

The concept of probability is fundamental in various fields such as mathematics, statistics, and even in everyday life. The probability of the simultaneous occurrence of two events A and B is a critical concept in probability theory. According to the definition, the probability of A and B occurring at the same time is equal to the probability of A multiplied by the conditional probability of B given that A has occurred. This equation is also valid in the reverse case, where the probability of B and A occurring simultaneously is equal to the probability of B multiplied by the conditional probability of A given that B has occurred.

Understanding the relationship between the probability of two events and their conditional probabilities is essential in predicting the likelihood of these events happening together. In real-life situations, this concept can be used to determine the probability of two events such as the success of a product launch and the corresponding increase in sales. The probability of these two events occurring simultaneously can be predicted by analyzing the probability of the product launch's success and the conditional probability of sales increasing given that the product launch is successful.

The average velocity for the [3,4] is 27m/s and for [4,5] is 37m/s

The average velocity can be found by taking the derivative of the position function and evaluating it at the midpoint of the interval.

The average velocity on the interval [3,4] is given by (s(4) - s(3)) / (4 - 3), which is equal to (s(4) - s(3)) / 1. Using the position function, s(t) = 5t^2 - 8t + 13, we find that s(4) = 5(4²) - 8(4) + 13 = 61 and s(3) = 5(3²) - 8(3) + 13 = 34. Therefore, the average velocity on the interval [3,4] is (61 - 34) / 1 = 27 m/s.

The average velocity on the interval [4,5] is given by (s(5) - s(4)) / (5 - 4), which is equal to (s(5) - s(4)) / 1. Using the position function, s(t) = 5t² - 8t + 13, we find that s(5) = 5(5²) - 8(5) + 13 = 98 and s(4) = 5(4²) - 8(4) + 13 = 61.

The value of the integral is 8pi/5^5. To evaluate this expression, we need to set up the triple integral in spherical coordinates, since the ball has a spherical shape with center at the origin.

We have:

yyyb sx^2 + y^2 + z^2 dV

In spherical coordinates, we have:

x = r sin(phi) cos(theta)
y = r sin(phi) sin(theta)
z = r cos(phi)

where r is the distance from the origin to the point (x, y, z), phi is the angle between the positive z-axis and the line connecting the origin to the point, and theta is the angle between the positive x-axis and the projection of the line onto the xy-plane.

Since the ball has center at the origin and radius 5, we have:

0 <= r <= 5
0 <= phi <= pi
0 <= theta <= 2pi

Using the Jacobian transformation, we have:

dV = r^2 sin(phi) dr dphi dtheta

Substituting into the integral, we have:

yyyb sx^2 + y^2 + z^2 r^2 sin(phi) dr dphi dtheta

= yyyb s(r^4 sin(phi)) dr dphi dtheta

= s(0 to 5) s(0 to pi) s(0 to 2pi) r^4 sin(phi) dr dphi dtheta
