A vector diagram showing the vector OE denoted by a + 2b is as attached.

Vector diagrams can be used to improve visualization and understanding of the magnitude and direction of vectors, and more importantly how multiple vectors interact.

For example, if Peter is pushing a heavy container towards the west, while John is pulling it in the northwest direction, in what direction does the container actually move?

A vector diagram is what will be useful in finding the answer.

Now, we see the vectors  OC and OD denoted by a + b and a − b in the attached diagram. Now, if we want to find a + 2b, we know that a + b will be a resultant but by use of vector analysis, we can plot a + 2b as seen in the first vector diagram attached.

Step-by-step explanation:

To find the median in a set of data, we first need to arrange the numbers in ascending order.

2,3,3,5,5,5,5,7,8

The median is the middle value of the set. Since there is an even number of data points in this set, the median is the average of the two middle values, which are 5 and 5.

So the median = (5+5)/2 = 5.

A concentration of the majority of  Muslim population of the country is on one island, leading to ethnic separatism.

Ethnic Separatism is the process by which a nation or ethnic group makes efforts to become more autonomous from the central government of a state, or even secedes, when it is unhappy with any combination of social, economic, and political conditions in the nation in which it is located.

When an ethnic group actively works to assert its rights and importance, ethnic nationalism is the result. When it serves the interests of the state, governments may support ethnic nationalism as a project; however, for a variety of reasons, ethnic nationalism may also pose a threat to the state. Separatism based on ethnicity is one of these causes. Find out what ethnic separatism is, some examples of it, and more by continuing to read.

To determine: the triangle's third side's length.

Since b and c are the lengths of a triangle's sides, let S be the length of the angle that bisects the given sides.

Suppose that angle A is 2α.

ABC's area is equal to (1/2) bcsin2α.

ADC's area is (1/2) bSsinα.

ADB = (1/2) cSsinα Area

Area of ABC is equal to Area of ADC plus Area of ADB.

The equation is (1/2) bcsin2α = (1/2) bSsinα + (1/2) cSsinα.

=> bcsin2α = (b + c) Ssinα

=> bc2sinαcosα =  (b + c) Ssinα

=> cosα =  (b + c) S /2bc

cos2α = 2cos²α  - 1

Answer:

[tex]\displaystyle{f'(x)=\dfrac{9}{4}x\left(8x^4+x^2-1\right)^{\frac{1}{8}}(16x^2+1)}[/tex]

Step-by-step explanation:

Given the function [tex]\displaystyle{f(x)=\sqrt[8]{\left(8x^4+x^2-1\right)^9}}[/tex]. We can rewrite the function in exponential form as [tex]\displaystyle{f(x)=\left(8x^4+x^2-1\right)^{\frac{9}{8}}}[/tex]. Here, we have to know the power rules and the chain rule:

[tex]\displaystyle{f(x) = u^n \to f'(x) = nu^{n-1} \cdot \dfrac{du}{dx}}[/tex]

Therefore, from the above formula, we will have:

[tex]\displaystyle{f'(x)=\dfrac{9}{8}\left(8x^4+x^2-1\right)^{\frac{9}{8}-1} \cdot \dfrac{d}{dx}\left(8x^4+x^2-1\right)}\\\\\displaystyle{f'(x)=\dfrac{9}{8}\left(8x^4+x^2-1\right)^{\frac{9}{8}-\frac{8}{8}} \cdot \dfrac{d}{dx}\left(8x^4+x^2-1\right)}\\\\\displaystyle{f'(x)=\dfrac{9}{8}\left(8x^4+x^2-1\right)^{\frac{1}{8}} \cdot \dfrac{d}{dx}\left(8x^4+x^2-1\right)}[/tex]

Next, we derive the function 8x⁴ + x² - 1 by applying the power rules:

[tex]\displaystyle{f(x) = x^n \to f'(x) = nx^{n-1} \cdot \dfrac{dx}{dx} \to f'(x)=nx^{n-1}}[/tex]

Also, deriving any constants will result in 0 always.

Therefore:

[tex]\displaystyle{\dfrac{d}{dx}\left(8x^4+x^2-1\right)} = 4\cdot 8 x^{4-1} + 2\cdot x^{2-1} - 0}\\\\\displaystyle{\dfrac{d}{dx}\left(8x^4+x^2-1\right)} = 32x^3 + 2x}[/tex]

Thus, we will have:

[tex]\displaystyle{f'(x)=\dfrac{9}{8}\left(8x^4+x^2-1\right)^{\frac{1}{8}} \cdot (32x^3+2x)}\\\\\displaystyle{f'(x)=\dfrac{9}{8}\left(8x^4+x^2-1\right)^{\frac{1}{8}} \cdot 2x(16x^2+1)}\\\\\displaystyle{f'(x)=\dfrac{9}{4}x\left(8x^4+x^2-1\right)^{\frac{1}{8}}(16x^2+1)}[/tex]

Therefore, the derivative is:

[tex]\displaystyle{f'(x)=\dfrac{9}{4}x\left(8x^4+x^2-1\right)^{\frac{1}{8}}(16x^2+1)}[/tex]

or you can rewrite in the form of surd as:

The  95% confidence interval for the true average dollar loss in burglaries rounded to the nearest dollar amount is 629 to 727

The variance of  a variate X is the arithmetic mean of the squares of all the deviations of X from the arithmetic mean of the observations and it is denoted by Var(X) or σ². The spread of statistical data is measured by the standard deviation. Distribution measures the deviation of data from its mean or average position. The positive square root of the variance of a variate X is known as the standard deviation.    

Given here: Sample mean x=678, Sample size n=500, Standard deviation σ=560

Standard error=σ.x=σ/√n

                               =560/√500

                               =25.044

Now for a 95% Class interval the value of z=1.960

The margin of error, E=Z×standard error

                             =49.08624

Lower bound=628.9147

upper bound=728.0854

1) y-coordinate of the vertex of y = x^2 + 2x - 1 is -1.

2) The statement "the vertex of quadratic function f is (-b/2a, f(-b/2a))" is true.

3) The equation y = -2x^2 - 12x - 17 has a maximum.

What is Quadratic Equation?

A quadratic equation is any equation in algebra that can be rearranged in standard form as where x represents an unknown value and a, b, and c represent known numbers.

1) y = x^2 + 2x - 1 is the equation of a parabola in vertex form.

In vertex form, the equation of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

So, to find the y-coordinate of the vertex, we can substitute the values of a, h and k into the equation and get the y-coordinate.

For the equation y = x^2 + 2x - 1, the vertex is (-1, -1), where -1 is the y-coordinate.

So, the y-coordinate of the vertex of y = x^2 + 2x - 1 is -1.

2) True.

The vertex of a quadratic function f(x) = ax^2 + bx + c is the point on the parabola that represents the graph of the function where the parabola changes direction from opening upward to opening downward or vice versa.

The x-coordinate of the vertex is given by (-b/2a), and the y-coordinate is given by f(-b/2a), where a, b, and c are constants.

So, the statement "the vertex of quadratic function f is (-b/2a, f(-b/2a))" is true.

3) maximum

The equation y = -2x^2 - 12x - 17 is a quadratic function, and it is in vertex form.

The leading coefficient is -2 which is negative, so the parabola opens downward, which means the vertex of the parabola represents the maximum point of the function. Therefore, the equation y = -2x^2 - 12x - 17 has a maximum.

The largest possible value for the probability of A4 is 0.2000

Since A1, A2, A3, and A4 are events from a common sample space, the sum of their probabilities must be less than or equal to 1.

So, the sum of the probabilities of the events can be expressed as:

P(A1) + P(A2) + P(A3) + P(A4) = 1

From the question, we have

P(A1) = P(A2) = P(A3) = 0.3

Also, we have that

Al and A2 occur simultaneously with a probability of 0.1

This means that the initial equation becomes

P(A1) + P(A2) - P(A1 and A2) + P(A3) + P(A4) = 1

Where

P(A1 and A2) = 0.2

So, we have
