The probability of obtaining an increasing (non-decreasing) sequence after 4 draws with replacement from 6 balls labelled 1-6 is 1/15.

To explain the answer, we can first consider the number of possible combinations of four numbers that can be drawn from the six numbers. Since each draw is done with replacement, each draw has the same probability and the same six numbers can be chosen. Thus, there are 6 x 6 x 6 x 6 = 1296 possible combinations.

Next, we can calculate the number of possible increasing (non-decreasing) sequences. If the first number drawn is 1, then the remaining three numbers must be greater than or equal to 1. Thus, the second number can be 1, 2, 3, 4, 5, or 6, the third number can be 1, 2, 3, 4, 5, or 6, and the fourth number must be 6. There are 6 x 6 x 1 = 36 possible increasing sequences if the first number drawn is 1. If the first number drawn is 2, then the second number can be 2, 3, 4, 5, or 6 and the remaining two numbers must be greater than or equal to 2. Thus, the third number can be 2, 3, 4, 5, or 6, and the fourth number must be 6. There are 5 x 5 x 1 = 25 possible increasing sequences if the first number drawn is 2. This process can be repeated for the remaining numbers, 3, 4, 5, and 6. The total number of increasing (non-decreasing) sequences is the sum of these possibilities, which is 36 + 25 + 15 + 6 + 1 = 83.

Therefore, the probability of obtaining an increasing (non-decreasing) sequence after 4 draws with replacement from 6 balls labelled 1-6 is 83/1296 = 1/15.

A 7075-T6 aluminum alloy is loaded in tension. Initially the 10mm x 100mm x 500mm plate has a 4-mm single-edge through-the-thickness crack. first, the 7075-T6 aluminum alloy's maximum tensile stress has to be determined. Then, using the maximum tensile stress and the Griffith theory, the maximum allowable tensile stress can be calculated

.A) Validity of the TestInitially, the 10mm x 100mm x 500mm plate has a 4-mm single-edge through-the-thickness crack. As a result, the tensile test cannot be deemed valid since the presence of a crack may alter the aluminum alloy's tension stress and disrupt the test's accuracy. This means that the test specimen must be free of defects such as scratches, notches, cracks, etc.

B) Calculation of the Maximum Allowable Tensile StressA 7075-T6 aluminum alloy has an ultimate tensile strength of 572 MPa and a fracture toughness of 24.9 MPa√m. the material in this case is ductile, the maximum allowable tensile stress (σm) can be calculated asσm

= [(2 × γ · E) / πa] 1/2where a is the length of the crack, E is Young's modulus, and γ is the surface energy.γ = √(2σf y

= 78.6 N/m (σf is the fracture stress, and G is the fracture toughness)σf

= 572 MPaG

= 24.9 MPa√mE

= 71.7 GPa (from table)We can substitute the values of E, γ, a, and σf into the above equation.σm

= [(2 × 78.6 N/m × 71.7 GPa) / π × 4 × 10⁻⁶ m] 1/2σm

Let's call the length of each of the other two sides x. Since the triangle is isosceles, it has two sides of equal length. Therefore, the perimeter of the triangle can be expressed as 6 + x + x Simplifying this equation, we get  2x + 6 We know that the perimeter is 22 cm so we can set up an equation and solve for x. 22 = 2x + 6 Subtracting 6 from both sides, we get  16 = 2x Dividing both sides by 2, we get x=8

The missing sides are;

1) 25

2) 29

3) 14

4) 19

5) 46

6) 4

For a right triangle with an angle θ, the trigonometric ratios are defined as follows:

Sine (sin): the ratio of the length of the side opposite the angle to the length of the hypotenuse. So, sin(θ) = opposite/hypotenuse.

Cosine (cos): the ratio of the length of the adjacent side to the length of the hypotenuse. So, cos(θ) = adjacent/hypotenuse.

1) sin 29 = 12/x

x = 12/sin 29

x = 25

2) Cos 16 = x/30

x = 30 cos 16

= 29

3) Tan 58 = 22/x

x = 22/Tan 58

x = 14

4) Tan 51 = x/15

x = 15 tan 51

if two sides of a triangle are 7 then their sum is only 14 and it would need to be greater than the third side of 15

Answer:

80 degrees

Step-by-step explanation:

What we see in this drawing is a triangle formed by three lines. In order to solve this problem, we need to know that when two lines intersect, the two angles formed are supplementary (meaning they add up to 180 degrees). For example, the 150-degree angle, and the angle right next to it (the angle on the left side of the triangle) add up to 180 degrees. This means that the left-most angle of the triangle is 180-150, which is 30 degrees

We can figure out the topmost angle of the triangle using the same method. We know that the angle outside the triangle is 130 degrees, so the angle right next to it (in this case, right below it), is 180-130, or 50 degrees.

Next, we use the fact that triangles are 180 degrees on the inside to figure out the third angle (the one on the right, right next to angle 1). We know that the other two angles are 30 and 50 degrees, and if you add that up, you get 80 degrees. The last angle, then, is 180-80, or 100 degrees.

Lastly, we know that the rightmost angle of the triangle and angle 1 add up to 180 degrees. In other words, 100+Angle1=180. Therefore, Angle 1 is 180-100 or 80 degrees.

The transfer function of the system, Y(s)/X(s), is Y(s)/X(s) = (y(s) - 4s^3X(s) + 8X(s) + s^2y(0) + sy'(0) + 4s^2x(0) + 4sx'(0))/(s^3 - 1).

The given differential equation represents a system described by a transfer function. To find the transfer function of the system, we need to take the Laplace transform of the equation.

Let's denote the Laplace transform of y(t) as Y(s) and the Laplace transform of x(t) as X(s), where s is the complex frequency.

Taking the Laplace transform of each term of the given differential equation, we get:

s^3Y(s) - s^2y(0) - sy'(0) - y(s) + 4s^3X(s) - 4s^2x(0) - 4sx'(0) - 8X(s) = 0

Now, let's rearrange the equation to solve for Y(s) in terms of X(s):

s^3Y(s) - y(s) + 4s^3X(s) - 8X(s) = s^2y(0) + sy'(0) + 4s^2x(0) + 4sx'(0)

Y(s)(s^3 - 1) = y(s) - 4s^3X(s) + 8X(s) + s^2y(0) + sy'(0) + 4s^2x(0) + 4sx'(0)

Dividing both sides by (s^3 - 1), we get:

Y(s) = (y(s) - 4s^3X(s) + 8X(s) + s^2y(0) + sy'(0) + 4s^2x(0) + 4sx'(0))/(s^3 - 1)

Therefore, the transfer function of the system, Y(s)/X(s), is:

Y(s)/X(s) = (y(s) - 4s^3X(s) + 8X(s) + s^2y(0) + sy'(0) + 4s^2x(0) + 4sx'(0))/(s^3 - 1)

This transfer function relates the Laplace transform of the output, Y(s), to the Laplace transform of the input, X(s).

First multiply through by 5 to eliminate the fraction

That's

Step-by-step explanation:

(a) The least integer n for which f(x) is o(\(x^n\)) is 4

(b) f(x) is not o(\(x^n\)) for any integer n.

(c) The least integer n for which f(x) is o(\(x^n\)) is 2.

(d) The least integer n for which f(x) is \(o(x^n)\) is 4.

(a) To determine the order of growth of f(x), we need to find a function g(x) such that limx→∞ f(x)/g(x) = 0. Let g(x) = \(x^4\). Then:

limx→∞ f(x)/g(x) = limx→∞ (\(2x^2 / x^4\) log(x)) = limx→∞ (2 / (\(x^2\) log(x)))

Using L'Hopital's rule:

limx→∞ (2 / (\(x^2\) log(x))) = limx→∞ (\(2x^{(-2)}\) / log(x) +\(4x^{(-3)} / log(x)^2\)) = 0

Therefore, f(x) is o(\(x^4\)). The least integer n for which f(x) is o(\(x^n\)) is 4.

(b) Let g(x) = \(x^7\). Then:

limx→∞ f(x)/g(x) = limx→∞ (\(3x^7 / x^7 (log(x))^4\)) = limx→∞ (\(3 / (log(x))^4\))

Using L'Hopital's rule four times:

limx→∞ (\(3 / (log(x))^4\)) = limx→∞ (\(3 (4!) / (log(x))^4\)) = ∞

Therefore, f(x) is not o(\(x^n\)) for any integer n.

(c) Let g(x) = \(x^2\). Then:

limx→∞ f(x)/g(x) = limx→∞ \((x^4 / (x^2 + 1)(x^4 + 1))\) = 0

Therefore, f(x) is o\((x^2)\). The least integer n for which f(x) is o(\(x^n\)) is 2.

(d) Let \(g(x) = x^4\). Then:

limx→∞ f(x)/g(x) = limx→∞ \((x^3 (5log(x)) / x^4)\) = limx→∞ (5 log(x) / x) = 0

Therefore, f(x) is\(o(x^4)\). The least integer n for which f(x) is \(o(x^n)\) is 4.

Answer: 3

Step-by-step explanation:

The required polar form of the equation is \(Z = 5/2cos30 - 5/2sin30i.\)

For the complex number z = (5sqrt(3))/4 - 5/4 * i the polar form is to be determined.

The number that constitutes real and imaginary numbers are called complex numbers. The standard form of complex number = a + bi

\(z = 5\sqrt{3}/4 - 5/4i\)
the polar form complex numbner  can be given as
\(z = rcos\theta +rsin\theta i\)   - - - - - -(1)
where r = \(\sqrt{a^2+b^2}\)
and \(\theta=tan^-\frac{b}{a}\)

Since a = 5√3/4 and b = -5/4
\(r = \sqrt{(5\sqrt{3}/4)^2+(5/4)^2}\)
r = 10/4
r = 5/2
Now,
\(\theta=tan^-\frac{b}{a}\)
\(\theta=tan^-\frac{-5/4}{5\sqrt{3}/4 }\\\theta=tan^-\frac{1}{\sqrt{3} }\\\theta=tan^-(-tan30)\\\theta=-30\)

Now the polar form is given by substituting the values of r and \(\theta\) in equation 1
Here,
\(z = 5/2cos30 +5/2sin(-30)i\\z = 5/2cos30-5/2sin30 i\)

Thus, the required polar form of the equation is \(Z = 5/2cos30 - 5/2sin30i.\)

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.
