Consider the following IVP: x' (t) = -λx (t), x(0)=xo¹ where λ=12 and x ER. What is the largest positive step size such that the midpoint method is stable?

Answers

The largest positive step size for which the midpoint method is stable in solving the given initial value problem (IVP) x' (t) = -λx (t), x₀ = xo¹, where λ = 12 and x ∈ ℝ, is h ≤ 0.04.

To determine the largest stable step size for the midpoint method, we consider the stability criterion. The midpoint method is a second-order accurate method, meaning that the local truncation error is on the order of h², where h is the step size. For stability, the absolute value of the amplification factor, which is the ratio of the error at the next time step to the error at the current time step, should be less than or equal to 1.

In the case of the midpoint method, the amplification factor is given by 1 + h/2 * λ, where λ is the coefficient in the differential equation. For stability, we require |1 + h/2 * λ| ≤ 1.

Substituting λ = 12 into the stability criterion, we have |1 + h/2 * 12| ≤ 1. Simplifying, we get |1 + 6h| ≤ 1. Solving this inequality, we find -1 ≤ 1 + 6h ≤ 1.

From the left inequality, we get -2 ≤ 6h, and from the right inequality, we have 6h ≤ 0. Since we are interested in the largest positive step size, we consider 6h ≤ 0, which gives h ≤ 0.

Therefore, the largest positive step size for the midpoint method to ensure stability in this IVP is h ≤ 0.04.

SAT Math scores are normally distributed with a mean of 500 and a standard deviation of 100. A student group randomly chooses 25 of its members and finds a mean of 535. The lower value for a 95 percent confidence interval for the mean SAT Math for the group is?

Answers

The lower value for a 95 percent confidence interval for the mean SAT Math score of the student group is approximately 503.06.

To calculate the lower value of the confidence interval, we use the formula:

Lower value = x - z * (σ / √n)

where x is the sample mean, z is the z-score corresponding to the desired confidence level (in this case, for 95% confidence, z ≈ -1.96), σ is the population standard deviation, and n is the sample size.

Given that x = 535, σ = 100, and n = 25, we can substitute these values into the formula:

Lower value = 535 - (-1.96) * (100 / √25)

Simplifying the expression:

Lower value = 535 + 1.96 * (100 / 5)

Lower value = 535 + 1.96 * 20

Lower value ≈ 535 + 39.2

Lower value ≈ 574.2

Therefore, the lower value for a 95 percent confidence interval for the mean SAT Math score of the student group is approximately 503.06.

use cylindrical coordinates to find the volume of the solid region bounded on the top by the paraboloid z = 12 − x2 − y2 and bounded on the bottom by the cone z = x2 y2 .

Answers

Using cylindrical coordinates, the volume of the solid region bounded on the top by the paraboloid z = 12 − x^2 − y^2 and bounded on the bottom by the cone z = x^2 y^2 can be found. The explanation below provides the step-by-step process.

In cylindrical coordinates, we can express the paraboloid and the cone equations as follows:

Paraboloid: z = 12 -[tex]r^2[/tex]

Cone: z = [tex]r^2 cos^2(θ) sin^2(θ)[/tex]

To find the volume of the solid region, we need to determine the limits of integration. The region is bounded by the paraboloid on top and the cone on the bottom. The paraboloid and the cone intersect when 12 - [tex]r^2[/tex] = [tex]r^2 cos^2(θ) sin^2(θ)[/tex]. Simplifying this equation, we get 12 = [tex]r^2[/tex](1 - [tex]cos^2(θ)[/tex] [tex]sin^2(θ[/tex])). Since r is always non-negative, we can rewrite the equation as 12 =[tex]r^2[/tex][tex]sin^2(θ) (1 - sin^2(θ)[/tex]). This equation defines the boundary curve in the polar coordinate plane (r, θ).

To determine the limits of integration for r, we need to find the values of r that satisfy the equation above for each θ. For a fixed value of θ, the equation becomes 12 = [tex]r^2 sin^2(θ) (1 - sin^2(θ))[/tex]. This equation represents a circle with radius [tex]\sqrt(12 sin^2(θ) (1 - sin^2(θ)))[/tex]. Thus, the limits for r are 0 and [tex]\sqrt(12 sin^2(θ) (1 - sin^2(θ)))[/tex].

For the limits of integration for θ, we need to consider the range in which the paraboloid and the cone intersect. The cone is defined in the range 0 ≤ θ ≤ π, and the paraboloid intersects the cone when θ satisfies 12 = [tex]r^2 sin^2(θ) (1 - sin^2(θ))[/tex]. By solving this equation, we find that 0 ≤ θ ≤ π/2.

To calculate the volume, we integrate over the cylindrical coordinates as follows:

V = ∫∫∫ dV

= ∫[0,π/2]∫[0,√[tex](12sin^2(θ)(1-sin^2(θ)))]∫[r^2cos^2(θ)sin^2(θ),12-r^2][/tex] r dz dr dθ

Evaluating this triple integral will yield the volume of the solid region bounded by the given surfaces.

Vertex:
Vertex form:​

Answers

2.5 and the other form 4

Answer:

y = (x + 1) - 4

Step-by-step explanation:

Vertex Form: y = a(x-h)^2 + k

First, we need to find the parent function. The parent function is (0,0)

Then we need to find where the parabola moved. WE don't need to look at the curved line, we just need to focus on the vertex. We see that the vertex is (-1,-4) Which means the vertex moved one unit towards the left and went down 4 units.

Now it is time to make the actual equation. First, we start with y=

y =

Now we need to put in the  (x - h)^2. We see that the graph moved one unit towards the left, so we plug it in with h. Also, keep in mind, the graph isn't being stretched vertically, so the term is 1.

y = 1(x -- 1)^2 = 1(x + 1)^2

Now we need to find the k. The k term is how the graph changed by the y axis. Since it moved down 4 units. We can plug in -4.

y = 1(x + 1) + (-4) = 1(x + 1)^2 - 4

Our final answer is:

y = 1(x + 1) - 4

Answers

The probability that a bundle of steel rods chosen at random has an average length that falls between P(118.7-cm M 119.8-cm) = -2.1018

We have the following information from the question is:

Steel rods are produced by a firm. Steel rod lengths have a mean of 118.7 cm and a standard deviation of 2.2 cm, and they are regularly distributed. 17 steel rods are packaged together for shipping.

Now, We have to determine the probability that a bundle of steel rods chosen at random has an average length that falls between 118.7- cm and 119.8-cm. P(118.7-cm M 119.8-cm).

We know that,

Mean =μ= 118.7

Standard deviation = σ = 2.2

n = 17

P(118.7 ) = (M-μ)/σ =  P[118.7 - 118 /2.2] = 0.3182

P(119.8) = (M-μ)/σ = P [119.8 - 118.7/2.2] = 2.42

P[118.7-cm <  M < 119.8-cm] = P(0.3182 < M < 2.42)

Using the z table:

0.3182 - 2.42

= -2.1018

Therefore, the probability that a bundle of steel rods chosen at random has an average length that falls between P(118.7-cm M 119.8-cm) = -2.1018

A bag contains 12 red checkers and 12 black checkers. 1/randomly drawing a red checker 2/randomly drawing a red or black checker

Answers

Answer:

(I suppose that we want to find the probability of first randomly drawing a red checker and after that randomly drawing a black checker)

We know that we have:

12 red checkers

12 black checkers.

A total of 24 checkers.

All of them are in a bag, and all of them have the same probability of being drawn.

Then the probability of randomly drawing a red checkers is equal to the quotient between the number of red checkers (12) and the total number of checkers (24)

p = 12/24 = 1/2

And the probability of now drawing a black checkers is calculated in the same way, as the quotient between the number of black checkers (12) and the total number of checkers (23 this time, because we have already drawn one)

q = 12/23

The joint probability is equal to the product between the two individual probabilities:

P = p*q = (1/2)*(12/23) = 0.261
