Given a table of data about total earnings and working hours,

Since its given that the data is proportional thus we can make an equation in terms of earning and working hours variable.

Let "e" be the earnings of Penelope and " h" be the total working hours

Thus,

e/h = 362/20

e = 18.1h

Therefore, a proportional equation for e in terms of h that matches the context will be  E = 18.1h.

The range of the progress of the construction company's six projects is 0.82.

The range of data is a measure of its spread. To calculate the range, you subtract the smallest value from the largest value.

The data for this problem is:

Project     Progress

 u                0.87

 v                0.31

 w               0.08

 x                0.05

 y                0.19

 z                0.5

In this case, the smallest value is 0.05 (project x) and the largest value is 0.87 (project u), so:

This means that the difference between the most advanced project and the least advanced project is 0.82. The range is an important measure of variability and helps in understanding the distribution of data, in this case, the progress of the construction projects.

The required integration-by-parts formula of given function is 5x (1/6) sin(6x) - (5/36) cos(6x) + C.

To evaluate the integral using integration-by-parts, we need to find two functions u and dv such that their derivative is equal to the integrated, and such that the anti-derivative of dv can be easily found. The integration-by-parts formula states that:

∫ uv = u(v) - ∫ v du

Let's choose u = 5x and dv = cos(6x) dx. Then, du = 5 dx and v = (1/6) sin(6x).

Using the integration-by-parts formula, we get:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - ∫ (1/6) sin(6x) 5 dx

The antiderivative of (1/6) sin(6x) 5 is (5/36) cos(6x), so:

∫ 5x cos(6x) dx = 5x (1/6) sin(6x) - (5/36) cos(6x) + C,

where C is the constant of integration.

The third side of triangle is 7/15.

The third side of a triangle must satisfy the triangle inequality, which states that the sum of any two sides must be greater than the third side. For a triangle with sides of 5 and 7 inches, the third side must be less than 5 + 7 = 12 inches. So, the possible lengths for the third side are 5, 6, 7, 8, 9, 10, 11 inches.

There are 15 total possible lengths for the strip, so the probability of randomly selecting a strip that can be used as the third side of a triangle with sides of 5 and 7 inches is 7/15.

Answer: cos(L) = 0.3684

Step-by-step explanation:

To solve, we need to identify what its asking first.

It wants us to find the value of the cos L

We know that Cosine is equivalent to the [tex]\frac{adjacent}{hypotenuse}[/tex] sides.

We also know that Cos L is an angle.

If we look at the picture, we first need to locate where L is. Then we need to find the cosine of it.

The adjacent side to L is 7.

The hypotenuse is 19.

we can rewrite this information into an equation:

[tex]cos (L)=\frac{7}{19}[/tex]

Since it wants cos L value to the nearest hundredth, we will use a calculator to divide.

cos(L) = 0.3684

After differentiation, The expression will be [tex]y = \frac{10}{9-t}[/tex].

Differentiation is one of the two central concepts in calculus, along with integration. Differentiation is a method for finding a function's derivative. Differentiation is a mathematical technique used to calculate the instantaneous rate of change of a function based on one of its variables. Velocity, or how quickly a distance varies in respect to time, is the most common example. Differentiation's opposite is finding an antiderivative.

If x and y are two variables, then dy/dx gives the rate of change of x in relation to y. A function's derivative is represented universally by the equation f'(x) = dy/dx, where y = f(x) is any function.

dy/dx

Now,

Given right expression is[tex]10(t+1)\frac{dy}{dt}-9y=9t[/tex]

[tex]9(y+t)=(10t-10)\frac{dy}{dt}[/tex]

After differentiation: [tex]\frac{s}{dx} (x^{n}) = nx^{n-1}[/tex]

The limit as x approaches 4 of f(x) is equal to -2 * 4^2 + 3 * 4 - 1 = 15.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is defined technically as a relation between a set of inputs and a set of potential outputs, where each input is associated to exactly one output. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The limit of f(x) as x approaches 4 is given by the value of f(4).

For x = 4, the definition of f(x) is:

-2x^2 + 3x - 1 = -2 * 4^2 + 3 * 4 - 1 = 15.

Therefore, the limit of f(x) as x approaches 4 is 15.

So, lim x→ 4 f(x) = 15.

The limit of f(x) as x approaches 4 is equivalent to -2 * 42 + 3 * 4 - 1 = 15.

The general term for the recurrence T(n) = 3T(n/2) + O(n) is O(nlog3). To get the answer, we should plug in k = log3. For the second recurrence, we cannot use the master theorem since it does not cover this case.

To solve this recurrence, we have to use the substitution method, where we guess a solution of the form T(n) = an^k and then prove that this is indeed a solution. This can be done by substituting the guessed solution back in to the recurrence. If the substitution works, then we have solved the recurrence. If not, we can try different values for a and k until the substitution works.

∫|sinx-cosx|dx

Using integration by parts, we can break this integral into two parts:

∫sinx dx - ∫cosx dx

Integrating each of these parts separately and substituting in the limits of integration from 0 to 2π, we get the following:

Since Fathi has $1.10 in his printing account, he will have -$59342.28 after printing the 474747-page PDF document.

Let's calculate how much Fathi will spend on printing the 474747-page PDF document.

Since Fathi is printing 2 pages on each side of a sheet, he uses 1/2 sheet of paper per 2 pages. And since each sheet of paper reduces his printing account balance by $0.25, he will spend $0.25 per 2 pages.

So, the cost per page is $0.25 / 2 = $0.125.

Now, we can calculate the total cost of printing the 474747 pages by multiplying the cost per page by the number of pages:

$0.125 * 474747 = $59343.38

Since Fathi has $1.10 in his printing account, he will have $1.10 - $59343.38 = -$59342.28 after printing the 474747-page PDF document.

Answer:

41/81

Step-by-step explanation:

There are a total of 4 blue marbles, 5 red marbles giving 9 total number of marbles

Let P(B₁) =Probability of getting a blue marble on the first draw

Let P(B₂) =Probability of getting a blue marble on the second draw

Let P(R₁) =Probability of getting a red marble on the first draw
Let P(B₂) =Probability of getting a red marble on the second draw

P(B₁) = Number of blue marbles ÷ total number of marbles = 4/9

Since the marble is replaced before the second draw, the total number of blue marbles and total number of both marbles is the same as for the first draw

P(B₂) = P(B₁) = 4/9 also

Probability of getting 2 blue marbles on 2 consecutive draws= P(B₁B₂)
= 4/9 x 4/9 = 16/81

P(R₁) = Number of red marbles ÷ total number of marbles = 5/9

P(getting a red marble on the second draw) = P(R₁R₂) = 5/9

Probability of getting 2 red marbles on 2 consecutive draws = P(R₁R₂)
= 5/9 x 5/9 = 25/81

Since we are asked the probability of getting 2 of the same color we can rephrase the same question as

P(two of same color) = P(B₁B₂ ∪ R₁R₂) = P(B₁B₂) + P(R₁R₂) = 16/81 + 25/81 = 41/81
