Step-by-step explanation:

Length of the shorter diagonal of the parallelogram will be 18.46 feet

Let the Parallelogram ABCD with BD and AC as it’s diagonal

According to the question,

AB = 17 feet

AD = 11 feet

As the opposite sides of a parallelogram are parallel and equal

Therefore, AB = CD = 17 feet

                AD = BC = 11 feet

Also the longer diagonal, BD = 22 feet

In triangle BCD, using cosine formula

\(BD^{2}\) = \(CD^{2}\) + \(BC^{2}\)- 2BC.CD.CosC

\(22^{2}\) = \(17^{2}\) + \(11^{2}\) - 2(11)(17)Cos C

484 = 289 + 121 - 374CosC

-0.197 = Cos C

C = arc Cos(-0.197)

Therefore, C = \(110^{0}\)

Now ∠C + ∠D = \(180^{0}\)

101+  ∠D = 180

∠D = \(79^{0}\)

Now, in triangle ADC

\(AC^{2}\) = \(AD^{2}\) + \(CD^{2}\) - 2AD.CD.CosD

 \(AC^{2}\) = \(11^{2}\) + \(17^{2}\) - 2(11)(17)Cos79

\(AC^{2}\) = 121 + 289 - 374Cos79

\(AC^{2}\) = 410 -364(.19)

\(AC^{2}\) = 340.84

AC = sqrt(340.84)

AC = 18.46

Step-by-step explanation:

well, the first solution that comes to my mind is :

8/4 + 5/1 = 7/1

2 + 5 = 7

the reason : the only numerator I can "cut" into integer pieces is 8.

5 and 7 are prime numbers.

so, it tried to keep 5 and 7 whole, and then add a part of 8 to make this equation true. and that worked right away.

No, the student is not correct. There is nothing wrong with Python based on the observed outcome of 7 heads and 3 tails in 10 coin tosses.

The outcome of 7 heads and 3 tails can occur within the realm of possibility when simulating fair coin tosses. In fact, if you were to repeat the simulation multiple times, you would likely see a range of different outcomes, including 7 heads and 3 tails.

Python provides various libraries and functions for random number generation, such as `random` or `numpy`, which are widely used and trusted for simulations. These libraries use well-established algorithms to generate pseudo-random numbers that approximate true randomness for most practical purposes.

It's important to understand that randomness inherently includes variability and the possibility of observing unexpected outcomes. In a small number of trials, the observed outcomes may deviate from the expected probabilities.

Therefore, the student's claim that something is wrong with Python based solely on the observed outcome of 7 heads and 3 tails in 10 coin tosses is not justified. The outcome falls within the range of what can be expected through chance and randomness.

No, the student's claim that there is something wrong with Python is incorrect. Python is a programming language that can be used to simulate coin tosses accurately. The result of 7 heads and 3 tails obtained by the student's simulation is not unexpected or indicative of an error in Python.

Python is a versatile programming language commonly used for data analysis, scientific computing, and simulations. Simulating a coin toss in Python involves using random number generation to represent the probability of heads or tails. Since a fair coin has an equal probability of landing on heads or tails, the outcome of a large number of coin tosses should be close to a 50% heads and 50% tails distribution.

In the case of the student's simulation, getting 7 heads and 3 tails in 10 coin tosses is within the range of possible outcomes. While it may not perfectly reflect the expected 50/50 distribution due to the small sample size, it does not suggest any issue with Python itself. To gain more confidence in the simulation's accuracy, the student could run the simulation multiple times with a larger number of tosses and compare the results to the expected probabilities.

For n ≥ 459, Algorithm A is better than Algorithm B when B uses n√n operations.

To determine the value of n₀ for which Algorithm A is better than Algorithm B when B uses n√n operations, we need to find the point at which the number of operations for Algorithm A is less than the number of operations for Algorithm B.

Algorithm A: 10n log n operations

Algorithm B: n√n operations

Let's set up the inequality and solve for n₀:

10n log n < n√n

Dividing both sides by n gives:

10 log n < √n

Squaring both sides to eliminate the square root gives:

100 (log n)² < n

To solve this inequality, we can use trial and error or graph the functions to find the intersection point. After calculating, we find that n₀ is approximately 459. Therefore, For n ≥ 459, Algorithm A is better than Algorithm B when B uses n√n operations.

R-1.3: For \($n \geq 14$\), Algorithm A is better than Algorithm B when B uses \($n^2$\) operations.

R-1.4: Algorithm A is always better than Algorithm B when B uses \($n\sqrt{n}$\) operations.

R-1.3:

Algorithm A: \($10n \log n$\) operations

Algorithm B: \($n^2$\) operations

We want to determine the value of \($n_0$\) such that Algorithm A is better than Algorithm B for \($n \geq n_0$\).

We need to compare the growth rates:

\($10n \log n < n^2$\)

\($10 \log n < n$\)

\($\log n < \frac{n}{10}$\)

To solve this inequality, we can plot the graphs of \($y = \log n$\) and \($y = \frac{n}{10}$\) and find the point of intersection.

By observing the graphs, we can see that the two functions intersect at \($n \approx 14$\). Therefore, for \($n \geq 14$\), Algorithm A is better than Algorithm B.

R-1.4:

Algorithm A: \($10n \log n$\) operations

Algorithm B: \($n\sqrt{n}$\) operations

We want to determine the value of \($n_0$\) such that Algorithm A is better than Algorithm B for \($n \geq n_0$\).

We need to compare the growth rates:

\($10n \log n < n\sqrt{n}$\)

\($10 \log n < \sqrt{n}$\)

\($(10 \log n)^2 < n$\)

\($100 \log^2 n < n$\)

To solve this inequality, we can use numerical methods or make an approximation. By observing the inequality, we can see that the left-hand side \($(100 \log^2 n)$\) grows much slower than the right-hand side \($(n)$\) for large values of \($n$\).

Therefore, we can approximate that:

\($100 \log^2 n < n$\)

For large values of \($n$\), the left-hand side is negligible compared to the right-hand side. Hence, for \($n \geq 1$\), Algorithm A is better than Algorithm B when B uses \($n\sqrt{n}$\) operations.

So, for R-1.4, the value of \($n_0$\) is 1, meaning Algorithm A is always better than Algorithm B when B uses \($n\sqrt{n}$\) operations.

In 1.41414141..... (41) is the repeating numbers after decimal. Therefore, it's a rational number.

Irrational numbers can't be written in the form of \(\frac{p}{q}\).

Examples : π, √3, 1.41456......

Given number in the question is 6.56556555....

In this number numbers after decimal are not repeating.

Therefore, given number is irrational.

The value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

According to the given question.

We have an equation

2x + 2/y = 4w + 2

Since, we have to find the value of x for the given equation

2x + 2/y = 4w + 2

Thereofore,

2x + 2/y = 4w + 2

⇒ 2(x + 1)/y = 2(2w + 1)    (taking 2 common from both the sides)

⇒ (x + 1)/y = 2w + 1

⇒ (x + 1) = y(2w + 1)         (multiplying both the sides by y)

⇒ x + 1 = 2yw + y

⇒ x = 2yw + y - 1         ( subtracting 1 both the sides)

Hence, the value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

Therefore, the fluid force on the top side is 55838.08 lb.

Given, the area of the top side of a piece of sheet metal is 4 square feet and it is submerged horizontally in 7 feet of water.

The weight-density of water is 62.4 pounds per cubic foot.To find: the fluid force on the top side.Solution:Fluid force formula is given by,

F = ρ * g * V

Where, ρ is the density of the fluidg is the acceleration due to gravityV is the volume of the fluid displaced.Furthermore, the volume of fluid displaced is equal to the volume of the metal sheet submerged in the water.

Therefore,Volume of fluid displaced = Volume of metal sheet submerged in the water = area of metal sheet * depth submerged

Volume of metal sheet submerged in the water = 4 square feet * 7 feet

= 28 cubic feet

Now, calculate the fluid force on the top side of the metal sheet by using the fluid force formula.

F = ρ * g * V

Here, the density of water,

ρ = 62.4 pounds per cubic foot

g = 32.2 ft/s² (the acceleration due to gravity)

V = 28 cubic feet∴

F = 62.4 * 32.2 * 28 lb

= 55838.08 lb

Therefore, the fluid force on the top side is 55838.08 lb.

Step-by-step explanation:

The focal length of the lens is 20 cm. The image should be at 60 cm from the lens.

Given a plant placed 6 squares distant from a convex lens. Since the refracted rays are converging the given lens is a convex lens.

Here each square is 5 cm along the horizontal direction.

The ray from the top of the plant pass through the lens and cross the principal axis at a distance 4 squares from the lens.

Hence the focal length of the lens, f = 4 x 5 = 20 cm.

We have the lens formula for convex lens.

i.e., 1/f=1/v+1/u ,

where v is the distance of real image from the center of the lens, u is the distance of the object from the center of the lens and f the focal length of the lens.

Here, u = 6 x 5 = 30 cm

So in order to find where the real image is produced,

we have 1/v = 1/f - 1/u

Therefore, v = uf /u-f = 30 x 20 / 30-20 = 60 cm.

Thus the real image is formed at a distance of 60 cm from the center of the lens.
