What’s the answer to the question

Answer: Mesocyclone

Step-by-step explanation:

1. (f∘c)'(t) = 10t⁴ * \(e^{(2t^5)\)

2. The directional derivative of f at the point (1, 2, 2) in the direction of the vector (5/√26)i + (5/√13)j is (80√26 + 60√13)/(√26√13).

3. ∂²f/∂x² = 484, ∂²f/∂y² = 1098, ∂²f/∂x∂y = 324, ∂²f/∂y∂x = 324.

1. Calculating (f∘c)'(t) using the first special case of the chain rule:

Let's start by evaluating f∘c, which means plugging c(t) into f(x, y):

f∘c(t) = f(c(t)) = f(2t², t³) = 5\(e^{(2t^2 * t^3)\) = 5\(e^{(2t^5)\)

Now, we can differentiate f∘c(t) with respect to t using the chain rule:

(f∘c)'(t) = d/dt [5\(e^{(2t^5)\)]

Applying the chain rule, we get:

(f∘c)'(t) = 10t⁴ * \(e^{(2t^5)\)

Final Answer: (f∘c)'(t) = 10t⁴ * \(e^{(2t^5)\)

2. Finding the directional derivative of f(x, y, z) = 2z²x + y³ at the point (1, 2, 2) in the direction of the vector 5/√26 i + 5/√13 j:

The directional derivative of f in the direction of a unit vector u = ai + bj is given by the dot product of the gradient of f and u:

∇f = (∂f/∂x, ∂f/∂y, ∂f/∂z) is the gradient of f.

∇f = (2z², 3y², 4xz)

At the point (1, 2, 2), the gradient ∇f is (2(2²), 3(2²), 4(1)(2)) = (8, 12, 8).

The directional derivative is given by:

D_u f = ∇f · u = (8, 12, 8) · (5/√26, 5/√13)

D_u f = 8(5/√26) + 12(5/√13) + 8(5/√26) = (40/√26) + (60/√13) + (40/√26)

Simplifying and rationalizing the denominator:

D_u f = (40√26 + 60√13 + 40√26)/(√26√13) = (80√26 + 60√13)/(√26√13)

Final Answer: The directional derivative of f at the point (1, 2, 2) in the direction of the vector (5/√26)i + (5/√13)j is (80√26 + 60√13)/(√26√13).

3. Finding all second partial derivatives of the function f(x, y) = xy⁴ + x⁵ + y⁶ at the point (2, 3):

To find the second partial derivatives, we differentiate f twice with respect to each variable:

∂²f/∂x² = ∂/∂x (∂f/∂x) = ∂/∂x (4xy⁴ + 5x⁴) = 4y⁴ + 20x³

∂²f/∂y² = ∂/∂y (∂f/∂y) = ∂/∂y (4xy⁴ + 6y⁵) = 4x(4y³) + 6(5y⁴) = 16xy³ + 30y⁴

∂²f/∂x∂y = ∂/∂x (∂f/∂y) = ∂/∂x (4xy⁴ + 6y⁵) = 4y⁴

∂²f/∂y∂x = ∂/∂y (∂f/∂x) = ∂/∂y (4xy⁴ + 5x⁴) = 4y⁴

At the point (2, 3), substituting x = 2 and y = 3 into the derivatives:

∂²f/∂x² = 4(3⁴) + 20(2³) = 324 + 160 = 484

∂²f/∂y² = 16(2)(3³) + 30(3⁴) = 288 + 810 = 1098

∂²f/∂x∂y = 4(3⁴) = 324

∂²f/∂y∂x = 4(3⁴) = 324

Therefore, ∂²f/∂x² = 484, ∂²f/∂y² = 1098, ∂²f/∂x∂y = 324, ∂²f/∂y∂x = 324.

The largest value of x that satisfies the inequality is approximately -1.8639.

To find the largest possible value of x that satisfies the inequality 1/(x + 2)⁶ > 1,000,000, we can start by rearranging the inequality:

1/(x + 2)⁶ > 1,000,000

Taking the reciprocal of both sides:

(x + 2)⁶ < 1/1,000,000

Now, let's take the sixth root of both sides:

x + 2 < (1/1,000,000)\(}^{1/6\)

Calculating the right side:

x + 2 < 0.1361

Subtracting 2 from both sides:

x < 0.1361 - 2

x < -1.8639

Therefore, the largest value of x that satisfies the inequality is approximately -1.8639.

Step-by-step explanation:

To find the perimeter of a triangle, add up the length of all three sides of the triangle.

Here, the sides of the triangle are "x+6", "x+6", and "2x-10". When you add up all three sides of the triangle, it should be equal to the perimeter, 30. So:

(x+6) + (x+6) + (2x-10) = 30

We can simplify this equation:

(2 * (x+6)) + (2x-10) = 30

2x + 12 + 2x - 10 = 30

4x + 2 = 30

Answer D: 4x + 2 = 30

The completely factored form of the polynomial is 7x² (x + 6) (x - 4)

Given,

The polynomial ; 7x⁴ + 14x³ - 168x²

We have to find the complete factored form of this polynomial;

Polynomial;

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable).

Here,

The polynomial is  7x⁴ + 14x³ - 168x²

Now,

Factorize the polynomial using common factors;

That is,

7x⁴ + 14x³ - 168x²

7x² (x² + 2x - 24)

Solve x² + 2x - 24 using quadratic formula;

That is,

\(\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}\) = \(\frac{-2(+-)\sqrt{2^{2} -4*1*-24} }{2*1}\) = \(\frac{-2(+-)\sqrt{4-96} }{2}\) = -2±√-92 / 2

Now,

Solve

-2 + √-92 / 2 = 3.79 ≈ 4

Solve

-2 - √-92 / 2 = -5.79 ≈ -6

Then,

The factors will be (x - 4) and (x + 6)

So,

7x² (x + 6) (x - 4) will be the factored form of the polynomial.

Option B. False is the answer. We can say it is False, using the Similarity of the triangle concept.

What is a Similar Triangle?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "." If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. The polygon with three sides is a triangle. In order for two triangles to be comparable, their corresponding sides must be in proportion to one another and their corresponding angles must be the same.

Properties of Similar Triangle:

1. Despite having the same form, each might have different sizes.

2. There are no matching angles that are not equal.

3. Similar equivalent side ratios exist.

Formula:

Two triangles are said to be similar if their respective sides are proportionate and their corresponding angles are congruent. As a result, using another triangle, we may determine the dimensions of one triangle. With the use of the formulae shown below, we can determine the pertinent angles and side lengths for triangles ABC and XYZ if they are two comparable triangles.

B = Y, C = Z, and A = X

BC/YZ = AC/XZ when AB/XY =

The set of all two-letter strings can be thought of as an ordered pair of two letters, where each letter can be selected from the alphabet {a, b, ..., z}.

Since there are 26 letters in the alphabet, there are 26 choices for the first letter in the string. For the second letter, however, there are only 25 choices, since we cannot repeat the letter selected for the first position. Thus, the number of different two-letter strings is the product of the number of choices for each letter, which is 26 * 25 = 650.

This problem illustrates the concept of counting principles, specifically the product rule of counting. The product rule states that the total number of outcomes for a sequence of events is the product of the number of outcomes for each event. In this case, the two events are the selection of the first letter and the selection of the second letter. By applying the product rule, we can easily determine the total number of possible two-letter strings.

This type of problem is commonly encountered in combinatorics, which is the branch of mathematics concerned with counting and arranging objects. The ability to count and calculate the number of possible outcomes is important in many fields, including probability theory, statistics, and computer science.

The critical value of z for each hypothesis  test is 2.326

In this question, we are asked to use Excel to find the critical value of z for each hypothesis test. We are given a 2 percent level of significance for a two-tailed test. To find the critical value, we can use the NORM.S.INV function in Excel. The syntax for this function is =NORM.S.INV(probability).

We can enter the probability as 1 - (alpha / 2) for a two-tailed test, where alpha is the level of significance. We can then round the result to three decimal places.

To find the critical value for a 2 percent level of significance, two-tailed test, we can follow these steps:

Step 1: Calculate the value of alpha

Alpha = 2% = 0.02

Step 2: Calculate

1 - (alpha / 2)1 - (alpha / 2)

= 1 - (0.02 / 2)

= 0.99

Step 3: Use the NORM.S.INV function in Excel=NORM.S.INV(0.99)

This gives us a critical value of z = 2.326.

Therefore, the critical value of z for the hypothesis test with a 2 percent level of significance and a two-tailed test is 2.326.

Answer is given below :

Step-by-step explanation:

If the test statistic value falls within the critical region, we reject the null hypothesis (H0) at the given significance level (α).

If the test statistic value falls outside the critical region, we do not reject the null hypothesis.

To determine the decision regarding the null hypothesis based on a test statistic value and a critical region, we need to compare the test statistic value to the critical value(s) of the test.

Since the question does not provide information about the significance level or the directionality of the test, we cannot determine the critical region or make a decision about the null hypothesis based on the test statistic value alone.

More information is needed to interpret the result of the test.

At the specified significance level (), we reject the null hypothesis (H0) if the test statistic value is inside the crucial zone.

If the test statistic result is outside of the acceptable range, the null hypothesis is not rejected.

The test statistic value to the test's critical value(s) in order to decide whether to reject the null hypothesis based on a test statistic value and a crucial area.

We cannot establish the crucial area or choose the null hypothesis based only on the test statistic value since the question does not specify the significance level or directionality of the test.
