It is not possible to determine the area of square 3 based on the information given. The area of a square is determined by its side length, which is not mentioned in the problem. In order to find the area of a square, you need to know the length of at least one side. The perimeter of a square, which is the total length of all its sides, is not sufficient to determine the area of the square. You would need to know the side length of square 1 in order to calculate its area.

Answer:400

Step-by-step explanation:

Answer:

y=(1/2)x-1

Step-by-step explanation:

Since you know that this line is perpendicular to the given equation, you also know that the slope of the line will be the opposite reciprocal to that of the given equation. Therefore:

slope= 1/2

Now, since you also know that the lines intersect at the point (-4,2), you just have to plug these numbers into the x and y in the equation to solve for b.

(2)=(1/2)(-4)+b

b=-1

Therefore, the equation is

y=(1/2)x-1

Using limits, it is found that the statement which describes the end behavior of the function f(x) is: As x approaches negative infinity, f(x) approaches positive infinity.

How we find the end behavior of a function f(x)?

It is given by the limit of f(x) as x approaches both positive infinity and negative infinity.

In this problem, the function is:

f (x) =   1/7 | x - 4 | + 3

Hence, the limits are:

[tex]\lim_{n \to -\infty} f(x) = \lim_{n \to -\infty} [1/7 | x - 4 | + 3] = \frac{1}{7} |-\infty - 4| + 3 = \infty\\\\ \lim_{n \to \infty} f(x) = \lim_{n \to -\infty} [1/7 | x - 4 | + 3] = \frac{1}{7} |\infty - 4| + 3 = \infty\\[/tex]

Approaches positive infinity in both cases, hence as x approaches negative infinity, f(x) approaches positive infinity.

What is a quadratic equation ?

Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is:

ax² + bx + c = 0

Given:

y=[tex]x^{4} -7x^{2} +12[/tex]

Let [tex]x^{2}[/tex] = k

So , y = [tex]k^{2}[/tex] -7k+12

On simplifying/factorising the given equation  ,we get

y =  [tex]k^{2}[/tex] - 4k - 3k +12

On taking common ,we get

y = k(k-4) -3(k-4)

y =(k-3)(k-4)

Thus , on factorising and equating it to zero we get

(k-3)=0 or (k-4)=0

k=3 or k=4

Now , replacing k by [tex]x^{2}[/tex] ,we get

[tex]x^{2}[/tex] = 3 or  [tex]x^{2}[/tex] = 4

Answer:

x = - 5 , x = 7

Step-by-step explanation:

to find the zeros, let y = 0 , that is

x² - 2x - 35 = 0

consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (- 2)

the factors are - 7 and + 5 , since

- 7 × + 5 = - 35 and - 7 + 5 = - 2 , then

x² - 2x - 35 = (x - 7)(x + 5) = 0

equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 7 = 0 ⇒ x = 7

the matrix A, which is composed of all scalar multiples of the vector [6 3], and represents the reflection about the line L in R2.A = [[-6/7, 9/7],[9/7, 6/7]]

Let L be the line in R^2 which consists of all scalar multiples of the vector [6 3], then the equation of the line is y= (3/6)x.

We need to find the matrix A which represents the reflection about the line L.

Let (x1, y1) be any point on the line L and let (x2, y2) be its reflection about the line L.

Now, we know that the slope of the line L is 3/6, hence the slope of the normal to the line L is -6/3.

So, the equation of the normal to the line L is y = -(6/3)x. Now, we can use the point-slope form of the line equation to calculate the equation of the line passing through (x1, y1) and its reflection (x2, y2).

The line that connects (x1, y1) and (x2, y2) has the following equation:

Answer:

Step-by-step explanation:

You have triangles with two sides and the included angle given, or all three sides given. You want the measures of the missing sides or angles.

For triangle ABC, the law of cosines tells us ...

  c² = a² +b² -2ab·cos(C)

Solving for the third side, we get ...

  c = √(a² +b² -2ab·cos(C))

Solving for the angle, we get ...

  C = arccos((a² +b² -c²)/(2ab))

The names of the sides and vertices can be permuted, as long as the angle is between the given sides.

  a = √((7² +9² -2·7·9·cos(35°)) ≈ 5.176

The measure of side 'a' is about 5.2 units.

  C = arccos((8² +7² -10²)/(2·8·7)) = arccos(13/112) ≈ 83.33°

  A = arcsin((8/10)·sin(83.33°)) ≈ 52.62°

  B = arcsin((7/10)·sin(83.33°)) ≈ 44.05°

The last two angles are found using the law of sines:

  sin(A)/a = sin(B)/b = sin(C)/c

  b = √(230² +360² -2·230·360·cos(38°)) ≈ 228 . . . . feet

The third side measures 228 feet.

Additional comment

A calculator or spreadsheet can be programmed with the necessary formulas so that you can avoid a lot of repetitive work when you have several of these to solve. You need to make sure angles are treated appropriately, as the default is often radians, rather than degrees.

When solving for angles from three given sides, we like to solve for the largest angle first. That avoids any ambiguity when using the Law of Sines to find the other angles.

When using the Law of Sines to find a second angle after using the Law of Cosines, it can work well to find the smallest remaining angle. (In the first problem, that would be the angle opposite the side of length 7; in the last problem, that would be the angle opposite the side of length 230.)

By using the alternating series estimation theorem we found that the number of terms we need to add in order to find the sum with an error less than 0.0001 is 7.

We must employ one of the convergence tests to determine whether the provided series is convergent or divergent. The alternating series test, which states that a series converges if it takes the form ∑ [tex](-1)^{n}[/tex] x an, where 'an' is a decreasing sequence of positive terms, is the most applicable test for this series.

∑ [tex](-1)^{n}[/tex] x an

a n =  [tex]\frac{(n + 1)}{(n^2 + 2n + 3)}[/tex]

by taking the derivative of the expression for a n, this sequence is decreasing and showing that it is always negative. given by a'n =  [tex]\frac{(n + 1)}{(n^2 + 2n + 3)}[/tex] [tex]- \frac{(n + 1) X 2)}{(n^2 + 2n + 3)^2}[/tex]

=  [tex]\frac{(-2n - 2)}{(n^2 + 2n + 3)^2}[/tex]

for all values of n it is negative, therefore the sequence a n is decreasing. Thus, given series satisfies the conditions of the alternating series test. Therefore, the series is convergent.

The alternating series estimation theorem can be used to determine how many terms are required to be added in order to find the total with an error of less than 0.0001. This asserts that the first disregarded term in an alternating series is smaller than the error in the series' sum. The error in the sum of the series with N + 1 terms is therefore smaller than the value of the (N + 1)th term in the series if we add N terms to the series and the error is less than E.

Find the first term in the series that is less than 0.0001 in order to calculate the number of terms we must add to the series in order to find the total with an error smaller than 0.0001.

given series that a 1 = [tex]\frac{2}{4}[/tex] = 0.5, a 2 = [tex]\frac{3}{9}[/tex] = 0.333, a 3 = [tex]\frac{4}{16}[/tex] = 0.25, and a 4 = [tex]\frac{5}{25}[/tex] = 0.2. Since the first term that is less than 0.0001 is a 7 = [tex]\frac{8}{64}[/tex] = 0.125, Adding, 7 terms to the series in order to find the sum with an error less than 0.0001.

Hurdle rate is 55%.

Ellon aeronautics has an ROI of 8% based on revenues of $30,000. the expenses residual income is $27,000 and the investment turnover is 1.5. The hurdle rate is 55%.

Investment

Investment Mathematics provides an introductory analysis of investments from a quantitative viewpoint, drawing together many of the tools and techniques required by investment professionals.    

Residual Income

Residual income is calculated as net income less a charge for the cost of capital. This is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. The formula is: Residual Income = Net Income - Equity Charge    

The investment turnover using this formula

Investment turnover=Sales/invested capital

Investment turnover = ($27000 / $30,000) × 1.5

Investment turnover = 0.9 × 1.5

Investment turnover =1.35

The hurdle rate using this formula

Hurdle rate = ROI - Investment turnover

Hurdle rate = 8 - 1.35

Hurdle rate = 0.55 × 100

Hurdle rate = 55%

For two-sample t-tests, results cannot be compared between studies. The test statistic is given, as well as a p-value. This test is also known as a matched sample or paired t-test. It is assumption of normal distribution.

The paired-samples t-test, also known as the dependent-samples t-test, is a statistical technique used to determine whether the mean difference between two sets of observations is zero. In a paired-samples t-test, each subject or entity is measured twice to obtain a pair of observations. Common uses of the paired-samples t-test are case-control studies or repeated measures designs.

A normal distribution is a type of continuous probability distribution in which most data points cluster toward the middle of the range and the rest decrease symmetrically toward one extreme. The middle of the range is also called the mean of the distribution.

The normal distribution is also known as the Gaussian distribution or probability bell curve. It is symmetrical about the mean, indicating that values ​​close to the mean occur more frequently than values ​​far from the mean.

Assumption:

The Normalization Assumption is cautioned because so many experiments are based on the assumption of a normal distribution. is required. In most cases, the assumption of normality makes sense.

However, there is an important special case where this is not the case. Understanding the normal distribution assumptions helps researchers understand the limitations of their experiments and understand their own research and where it went wrong.

The assumption of normal distribution can be relaxed in some situations, but the analysis is more complicated. The simplest analysis is obtained when the physical process can be approximated by a normal distribution. However, even if the distribution is non-normal, it retains some basic properties. For example, you can assume symmetry, such as the t distribution, even if the distribution is not truly normal.

In fact, many different non-normal distributions are just variations of the normal distribution. For example, there are distributions with long tails that represent variations in a normal distribution. Such distributions are also common.

The reason for the normal distribution assumption is that it is usually the simplest mathematical model available. Moreover, it is remarkably ubiquitous, found in most natural and social phenomena. So the assumption of normality is usually a good first approximation.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.
