The time taken for the smokestack A is 22.5 hours.

The time taken for the smokestack B is 45 hours.

The time taken for the smokestack is calculated as follows;

Let's the rate at which smokestack B emits pollution = r

Then smokestack A = 2r

Their total rate of pollution combined;

= r + 2r

= 3r

The total amount of pollution they emitted after 15 hours;

= 3r x 15

= 45r pollution

The time taken for each to emit the same amount;

rate of B = r pollution/hr

time of B = 45r/r = 45 hours

rate of A = 2r

time of A = 45r/2r = 22.5 hours

Main Answer:

c₁ = 2, c₂ = 4, a₁ = 6, a₂ = 0, b₁ = 0, b₂ = 0.

Explanation:

In the given problem, we are provided with a periodic signal x(t) and we need to determine the coefficients c₁, c₂, a₁, a₂, b₁, and b₂ using the given Fourier series representation.

Step 1: Find c₁ and c₂:

c₁ is the coefficient of cos(wo₁t) in x(t), and c₂ is the coefficient of cos(wo₂t) in x(t). In the given signal x(t) = 2cos(5t) + 4cos(15t) + 6sin(20t), we can see that there is no term of the form cos(wo₁t) or cos(wo₂t). Therefore, c₁ and c₂ both equal 0.

Step 2: Find a₁ and a₂:

a₁ is the coefficient of cos(wo₁t) in x(t), and a₂ is the coefficient of cos(wo₂t) in x(t). We can calculate these coefficients using the formula:

an = (2/T) * ∫[0 to T] x(t) * cos(nwot) dt

For the given signal x(t) = 2cos(5t) + 4cos(15t) + 6sin(20t), we have:

a₁ = (2/1) * ∫[0 to 1] (2cos(5t) + 4cos(15t) + 6sin(20t)) * cos(wo₁t) dt

  = (2/1) * ∫[0 to 1] (2cos(5t)) * cos(wo₁t) dt

  = (2/1) * ∫[0 to 1] (2cos(5t)) * cos(5t) dt

  = (2/1) * ∫[0 to 1] (2cos²(5t)) dt

  = (2/1) * [∫[0 to 1] cos²(5t) dt]

  = (2/1) * [∫[0 to 1] (1 + cos(10t))/2 dt]

  = (2/1) * [(t/2) + (sin(10t))/(20)] (evaluated from 0 to 1)

  = 1/2 + sin(10)/(10)

Similarly, a₂ = 0 as there is no term of the form cos(wo₂t) in the given signal.

Step 3: Find b₁ and b₂:

b₁ is the coefficient of sin(wo₁t) in x(t), and b₂ is the coefficient of sin(wo₂t) in x(t). We can calculate these coefficients using the formula:

bn = (2/T) * ∫[0 to T] x(t) * sin(nwot) dt

For the given signal x(t) = 2cos(5t) + 4cos(15t) + 6sin(20t), we have:

b₁ = (2/1) * ∫[0 to 1] (2cos(5t) + 4cos(15t) + 6sin(20t)) * sin(wo₁t) dt

  = (2/1) * ∫[0 to 1] (6sin(20t)) * sin(5t) dt

There are total 95040 number of different groups of 5 items can be selected from 12 distinct item.

According to the given question.

Total number of items, n = 12

Total numbers of items to be selected, r = 5

Since, we have to determine the number of different groups of 5 items that can be selected from 12 distinct items. So, we will find the number of different groups by permulation formula i.e.

\(^{n} P_{r} = \frac{n!}{(n-r)!}\)

Where,

\(^{n} P_{r}\) is the total number of permutations.

n is the total number of objects.

r is teh total number of objects to be selected.

Therefore,

The number of different groups or permutaions of 5 items that can be selected from 12 distinct group

\(^{12} P_{5}\)

\(= \frac{12!}{(12-5)!}\)

\(= \frac{12!}{7!}\)

\(= \frac{12\times11\times10\times9\times8\times7!}{7!}\)

= 12 × 11 × 10 × 9 × 8

= 95040

Hence, there are total 95040 number of different groups of 5 items can be selected from 12 distinct item.

y(t) = A*cos(sqrt(31/5)*t) + B*sin(sqrt(31/5)*t), where A and B are constants determined by the initial conditions.

The given differential equation is 5y′′ + 31y = 0. To solve this second-order linear homogeneous differential equation, we assume the solution is of the form y(t) = e^(rt), where r is a constant to be determined. Substituting this into the equation, we get:

5r^2*e^(rt) + 31e^(rt) = 0

Dividing both sides by e^(rt), we obtain the characteristic equation:

5r^2 + 31 = 0

Solving this quadratic equation for r, we find:

r^2 = -31/5

Taking the square root of both sides:

r = ±sqrt(-31/5) = ±i*sqrt(31/5)

Since complex numbers are not allowed in the answer, we can express the solution in terms of sines and cosines using Euler's formula:

e^(i*theta) = cos(theta) + i*sin(theta)

Using this, we can rewrite the solution as:

y(t) = A*cos(sqrt(31/5)*t) + B*sin(sqrt(31/5)*t)

Here, A and B are determined by the initial conditions. We are not given specific initial conditions, so we cannot determine their values.

The solution to the given differential equation is y(t) = A*cos(sqrt(31/5)*t) + B*sin(sqrt(31/5)*t), where A and B are constants determined by the initial conditions.

The value 111.958 represents the y-intercept of the equation f(x) = 9.607x + 111.958.

In the context of the scenario, the y-intercept is the value of the dependent variable (number of fish deaths per year) when the independent variable (pollution index of the lake, represented by x) is equal to zero.

Interpreting the y-intercept (111.958) in this scenario, it means that when the pollution index of the lake is at zero (indicating no pollution), the model predicts that there would still be 111.958 fish deaths per year.

In practical terms, this suggests that there might be other factors contributing to the fish deaths apart from pollution. It could be natural causes, fishing activities, or other environmental factors not accounted for in the model.

It is important to note that the y-intercept provides the initial value or baseline when the independent variable has no effect, but it may not reflect the complete relationship between the variables. The slope of the equation (9.607) indicates the rate of change in fish deaths for each unit increase in the pollution index.

The predicted college gpa be for a student whose current high school

gpa = 3.2 is 2.9718.

In statistics, a scalar response and one or more explanatory factors are modeled using a linear approach called linear regression. Simple linear regression is the scenario in which there is only one explanatory variable; multiple linear regression is the scenario in which there are numerous explanatory variables.

When predicting a variable's value based on the value of another variable, linear regression analysis is utilized. The dependent variable is the one you're trying to forecast. The independent variable is the one that you are utilizing to forecast the value of the other variable.

The linear regression for Y (dependent variable) on X (independent variable) is given by:

Y = a + bX

where,

a be the y-intercept

b be the slope of the line

When the slope is positive (or negative), the regression line is presumed to be increasing, which gives rise to the characteristics for the assumption (or decreasing).

For a = 0.719, b = 0.704, and X = 3.2, the predicted college GPA exists,

Y′ = 0.719 + (0.704 \(*\) 3.2) = 2.9718

Therefore, the predicted college gpa be for a student whose current high school gpa = 3.2 is 2.9718.

tan M = \(\frac{3\sqrt{11} }{15} = \frac{\sqrt{11} }{5}\)

The value of x in the equation x degree + x degrees + 90 degrees + x/2 degree = 360 degrees is 108.

In order to solve for x in the equation:

X degree + x degree + 90 degree + x/2 degree = 360 degrees

We can start by simplifying the equation:

X + x + 90 + x/2 = 360

Combining like terms:

3/2x + X + 90 = 360

Next, let's isolate the terms involving x on one side of the equation:

3/2x + x = 360 - 90

Simplifying:

5/2x = 270

To solve for x, we need to multiply both sides of the equation by 2/5:

(2/5)(5/2x) = (2/5)(270)

x = 540/5

x = 108

Therefore, the value of x in the equation x degree + x degrees + 90 degrees + x/2 degree = 360 degrees is 108.
