Answer:

y=1/3x+0 or y=1/3x

Step-by-step explanation:

find the slope by taking two points and putting them in

y2 - y1/x2 - x1

so, (3,1) and (6,2) becomes 2-1/6-3 or 1/3 so, slope is 1/3

then to find y intercept you can put a point (6,2) and slope (1/3) into slope intercept form y - y1 = m(x - x1)

y - 2 = 1/3(x-6)

when you solve this you get y = 1/3x + 0, so y intercept is 0. you can also see. this on the graph given

The value of the iterated integral ∫[1,0] ∫[3y,y] ∫[x+y,0] 12xy dz dx dy is 0.

What is integral?

The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.

To evaluate the iterated integral, let's start by integrating with respect to z first, then x, and finally y.

∫[1,0] ∫[3y,y] ∫[x+y,0] 12xy dz dx dy

Integrating with respect to z, we have:

∫[1,0] ∫[3y,y] [12xyz]_[x+y,0] dx dy

Next, we integrate with respect to x:

∫[1,0] ∫[3y,y] [12xy(x+y)]_[x+y,0] dy

Simplifying the limits of integration, we get:

∫[1,0] ∫[3y,y] [12xy(x+y) - 12xy(x+y)] dy

The terms involving (x + y) cancel out, resulting in:

∫[1,0] ∫[3y,y] 0 dy

Integrating with respect to y, we have:

∫[1,0] [0]_[3y,y] dy

Now we can evaluate the integral:

∫[1,0] 0 dy = 0

Therefore, the value of the iterated integral ∫[1,0] ∫[3y,y] ∫[x+y,0] 12xy dz dx dy is 0.

Integral: To evaluate the integral ∫(4x)dx by completing the square, we can rewrite the integrand as a perfect square. The integrand can be expressed as 4(x) = (2x)^2.

∫(4x)dx = ∫(2x)^2 dx

Now, we can integrate using the power rule for integration:

= (2/3)(2x)^3 + C

= (8/3)x^3 + C

Therefore, the integral of 4x with respect to x is (8/3)x^3 + C, where C represents the constant of integration.

Derivative: To find the derivative of the exponential function y = x * e^(r * x), we can use the product rule of differentiation.

Let's differentiate term by term:

dy/dx = d/dx (x * e^(r * x))

Applying the product rule, we have:

dy/dx = x * d/dx(e^(r * x)) + e^(r * x) * d/dx(x)

The derivative of e^(r * x) with respect to x is r * e^(r * x), and the derivative of x with respect to x is 1. Substituting these values, we get:

dy/dx = x * (r * e^(r * x)) + e^(r * x) * 1

dy/dx = r * x * e^(r * x) + e^(r * x)

Therefore, the derivative of the exponential function y = x * e^(r * x) with respect to x is r * x * e^(r * x) + e^(r * x).

a) The actual distance between towns K and L is: 100 km

b) As shown in the attached file

c) The bearing of town L from town K is 117 degrees.

The scale of the map is given as:

1 cm to represent 50 km

Now, when we measure the distance between K and L on the map, we see that it gives us a distance of 2 cm.

Using the scale of 1 cm: 50 km, we can say that:

Actual distance between towns K and L = (2 * 50)/1 = 100 km

b) Using a compass and it’s 3cm aiming down {South} as seen in the attached photo. Then a line was drawn aiming {South} with a ruler. On the end of the line the (x) point was put there to get the mark.

If 300 people were sampled instead of 200, and the confidence level remained the same, it would produce a more accurate result.

Sampling means selecting the group that you will actually collect data from in your research. For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students. In statistics, sampling allows you to test a hypothesis about the characteristics of a population.

This is because a larger sample size allows for a better representation of the population, providing a more accurate result. Additionally, with a larger sample size, the confidence interval of the sample would be narrower, indicating a higher level of confidence in the accuracy of the result.

2/5th of a number is 40% of that number.

In order to calculate the percentage of a given number that is equal to 2/5 of that number, we must first convert the fraction to percentage form, which is as follows:

= 2/3 * 100

= 0.4 * 100

= 40%

We will use the following example to validate the aforementioned process:

Assume that it is 50.

First, 2/5 of 50 equals 2/5 * 50, or 20.

Second, 40% of 50 equals 40/100 * 50 = 0.4 * 50 = 20.

The equality of the two results is evident.

2/5 of a number is therefore 40% of that number.

What is a simple definition of a function?

As a set of inputs with one output for each, a function is defined as a relationship between them. A function, expressed simply, is an association between inputs where each input is connected to one and only one output. A domain, codomain, or range exists for every function. A function is often represented by the notation f(x), where x represents the input.

The equation of a vertical parabola written in vertex form is equal to

     f(x) = a(x - h )² + k

where

a is a coefficient

substitute

 f(x) = a( x - 2)²  - 8

Find the value of the coefficient a

take one point from the graph

(0,0)

substitute in the equation

 0 = a(0 -2)² - 8

 0 = 4a - 8

  a = 2

The function’s equation written in vertex form is

          f(x) = 2(x - 2)²- 8

Part b) What is the function’s equation written in factored form?

we know that

The equation of a vertical parabola written in factored form is equal to

  f(x) = a(x - x₁)(x- x₂)

Remember that the x-intercept is the value of x when the value of the function is equal to zero

Looking at the graph

The zeros or x-intercepts of the function are

x=0 and x=4

so

 f(x) = a(x- 0)(x- 4)

 f(x) = ax(x - 4)

The graph of 3x-2y≤6 is the third graph, for 3x-2y<6 is the first graph, for 3x-2y>6 is the fourth graph and for 3x-2y≥6 is the second graph. The solution has been obtained using concept of linear inequality.

What is linear inequality?

A linear inequality is one that would produce a linear equation if the equals relation were used instead of the inequality. When multiplying or dividing both sides by a negative number in order to solve the inequality, the direction of the inequality is reversed. The entire set of solutions to an inequality is known as the solution set.

We are given for graphs, of which two graphs are dotted and two are simple straight line graphs.

The dotted graphs are drawn for the inequalities having < or >

Whereas the simple straight line graphs are drawn for the inequalities having ≤ or ≥.

Now, to notice the shaded pattern, we will see whether the equations are true for (0,0) or not

1. 3x-2y≤6

⇒ 0≤6

So, the equation is true for the point.

Hence, the third graph represents this equation.

2. 3x-2y<6

⇒ 0<6

So, the equation is true for the point.

Hence, the first graph represents this equation.

3. 3x-2y>6

⇒ 0>6

So, the equation is false for the point.

Hence, the fourth graph represents this equation.

4. 3x-2y≥6

⇒ 0≥6

So, the equation is false for the point.

Hence, the second graph represents this equation.

Hence, the graphs are matched with the inequalities.

Since, there are multiple questions so, the question answered above is attached below.

The standard deviation of returns is 0.0665 when a person is holding stock and there are three possible outcomes.

To calculate the expected return, we multiply the probability of each state by its corresponding return and sum them up:

Expected return = (20% * 18%) + (55% * 9%) + (25% * -5%)

Expected return = 0.20 * 0.18 + 0.55 * 0.09 + 0.25 * (-0.05)

Expected return = 0.036 + 0.0495 - 0.0125

Expected return = 0.073

The expected return is 7.30%.

To calculate the standard deviation of returns, we need to find the variance first. The variance is calculated as the weighted sum of squared deviations from the expected return:

Variance = (20% * (18% - 7.30%)^2) + (55% * (9% - 7.30%)^2) + (25% * (-5% - 7.30%)^2)

Variance = 0.20 * (0.1077)^2 + 0.55 * (0.0177)^2 + 0.25 * (-0.123)^2

Variance = 0.00232 + 0.000173 + 0.001903

Variance = 0.004423

The standard deviation is the square root of the variance:

Standard deviation = √(0.004423)

Standard deviation = 0.0665

Therefore, the value obtained is 0.0665.
