The student covers a total distance of 22.05 kilometers in a week's time, walking between the park and the house each day.

To find the total distance covered by the student in a week's time, we need to calculate the distance covered in one round trip (from the house to the park and back) and then multiply it by the number of round trips in a week.

Given that the difference between the park and house is 1 kilometer and 575 meters, we can convert it to a total distance of 1.575 kilometers.

In a round trip, the student covers twice the distance between the park and the house, which is 1.575 kilometers * 2 = 3.15 kilometers.

Now, we need to determine how many round trips the student makes in a week. Let's assume the student makes one round trip each day.

Since there are 7 days in a week, the total distance covered by the student in a week's time is 3.15 kilometers * 7 = 22.05 kilometers.

Answer:

4% of 50% of 5 is 0.1

Use a calculator.

(Answer was deleted for "incorrect" as it was correct as that's what I got as an answer.)

The given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

To show continuity, we need to verify that the partial derivatives of ψ and φ with respect to x and y are equal. Let's calculate these partial derivatives:

∂ψ/∂x = 2y

∂ψ/∂y = 2x

∂φ/∂x = 2x

∂φ/∂y = -2y

From the above calculations, we can see that the partial derivatives of ψ and φ with respect to x and y are equal. Therefore, the condition for continuity, which requires the equality of partial derivatives, is satisfied.

To show irrotational flow, we need to verify that the curl of the velocity vector is zero. The velocity vector can be obtained from the stream function ψ and velocity potential φ as follows:

V = ∇φ x ∇ψ

Taking the curl of V:

∇ x V = ∇ x (∇φ x ∇ψ)

Using vector calculus identities and simplifying the expression, we find:

∇ x V = 0

Since the curl of the velocity vector is zero, the condition for irrotational flow is satisfied.

Therefore, based on the calculations and verifications, we can conclude that the given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

Step-by-step explanation:

Given,

the radius(r)of the cone's base = 8 cm

the height(h)of the cone = 8 cm

then the volume of cone

= 1/3 πr²h

= (1/3×22/7×8²×8 (substituting the value of r and h )

=(1/3×22/7×64×8)cm³

=(12544/21)cm³

=597.333cm³(ans)

If you face any doubt related to the solution please ask me

The volume of the cone is 536.38 cubic cm if the radius of the cone is 8 cm and the height of the cone is 8 cm.

The volume of a cone is the amount of space possessed by a cone in a three-dimensional plane. A cone contains a circular base, which suggests the base is made of a radius and diameter.

The volume can be defined as a three-dimensional space enclosed by an object or thing.

The formula for the volume of the cone,

\(\rm V=\dfrac{1}{3} \pi r^2h\)

r = radius of the circular base

h= perpendicular height of the cone

Here, r = 8 cm

h = 8 cm

So the volume of the given cone will be,

\(\rm V=\dfrac{1}{3} \pi r^2h\\\\\\=\dfrac{1}{3}\times\dfrac{22}{7}\times8^2\times8\\\\\\\)

V  = 536.38 cubic m

Volume =536.38 cubic cm

Thus, the volume of the cone is 536.38 cubic cm if the radius of the cone is 8 cm and the height of the cone is 8 cm.

The increasing the difference between sample means will result in a larger t statistic. This means that the difference between the two sample means is more likely to be statistically significant and less likely to be due to chance.

the t statistic is calculated by taking the difference between the sample means and dividing it by the standard error of the difference. When the difference between sample means increases, the numerator of the t statistic increases, while the denominator (the standard error) remains relatively constant. This leads to a larger t statistic and a smaller p-value, indicating stronger evidence against the null hypothesis.

increasing the difference between sample means has a significant effect on the independent-measures t statistic. It increases the strength of the evidence against the null hypothesis, making it more likely that the difference between the two groups is real and not due to chance.

A common everyday counting unit that is used to mean 12 of an object is a Dozen

Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.

Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."

A dictionary with keys 'normalize' and 'alpha' and values [True, False] and [1, 10, 100] respectively can be used to perform a grid search.

Grid search is a technique used to find the optimal hyperparameters for a machine learning model. In the case of determining if normalization should be used and testing different values of alpha, we need to provide the algorithm with a range of values for each hyperparameter. This can be done using a dictionary.

The keys in the dictionary would be 'normalize' and 'alpha', representing the hyperparameters we want to search for. The values for 'normalize' would be [True, False], representing the options for normalizing the data or not. The values for 'alpha' would be [1, 10, 100], representing the different values of alpha to test.

This dictionary can then be passed as an argument to the grid search algorithm, which will then perform a search through all possible combinations of these hyperparameters, evaluating the performance of the model for each combination and determining the optimal set of hyperparameters.

Step-by-step explanation:

Answer:

small triangle area = 1/2(8)(14) = 56 m²

bigger triangle area = 1/2(16)(14) = 112 m²

biggest triangle area = 1/2(24)(14) = 168 m²

there's 2 bigger triangles so you pick the bigger one you want

Answer:

smaller triangle area = 56m²

larger triangle area = 112m²

total area = 168m²

Step-by-step explanation:

Area of triangle = \(\frac{bh}{2}\)

where b = base length and h = height

smaller triangle dimensions

base length= 8m

height = 14m

* plug in the values into the formula *

\(area=\frac{8*14}{2} \\8*14 =112\\\frac{112}{2}=56\\A=56m^2\)

so we can conclude that the area of the smaller triangle is 56 square meters

larger triangle dimensions

base length = 16m

height = 14m

* plug in the values into the formula *

\(area=\frac{16*14}{2} \\16*14=224\\\frac{224}{2} =112\\A=112m^2\)

so we can conclude that the area of the larger triangle is 112 square meters

total area = the sum of the two triangle's area

total area = 112 + 56

112 + 56 = 168

hence the total area is 168 square meters

Hi , I can't understand the question...I think you have forgotten to give some value for variables... because it's not possible to get the answer without the value of variables

The given function is C(x) = 936 + 80x + 0.12x^2, where x represents the number of mountain bikes produced daily. The average cost function is also given by C(x).
To make the mountain bike as affordable as possible, the company should target a production level of 333.33 mountain bikes daily, where the average cost function is at its minimum. Rounded to 2 decimal places, the answer is

c = 333.33.

First, let's correct the given cost function: C(x) = 936x + 80x^2 + 0.12x^3. Now, we'll use the terms "function," "average," and "increases."

To find the average cost function, we need to divide the total cost function, C(x), by the number of mountain bikes produced daily, x. Let A(x) represent the average cost function:

A(x) = C(x) / x

Now, let's substitute C(x) into this equation:

A(x) = (936x + 80x^2 + 0.12x^3) / x

Simplify by canceling out an x term:

A(x) = 936 + 80x + 0.12x^2

To find the production level c where the average cost function decreases and then increases, we need to find the minimum point on the A(x) curve. To do this, we'll differentiate A(x) with respect to x to obtain the first derivative:

A'(x) = 80 + 0.24x

Now, set the first derivative equal to zero and solve for x:

80 + 0.24x = 0

0.24x = -80

x = c = -80 / 0.24

Round to 2 decimal places:

c ≈ 333.33

So, to make the mountain bike as affordable as possible, the company should target a production level of approximately 333.33 mountain bikes daily.
