Answer 1

Order of the side lengths EF, FG, and GE from least to greatest is EF < FG < GE.

Give a brief account on Law of Coslnes?

When the lengths of two sides and the size of the included angle are known (SAS) or when the lengths of all three sides are known (SSS), the Law of Cosines can be used to determine the remaining components of an oblique (non-right) triangle. We are unable to establish a solvable percentage in either of these scenarios, making it impossible to apply the Law of Sines.

According to the Law of Cosines:

c² = a² + b² - 2ab * cos(C)

With the exception of the third component, which equals zero if C is a straight angle and the Pythagorean Theorem results, this is similar to the Pythagorean Theorem. As a result, the Law of Cosines is a specific case of the Pythagorean Theorem.

Using the Law of Cosines

In the given triangle, we are given the measure of angle G and the length of side FG, so we can use the Law of Cosines to find the lengths of the other sides. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the relationship between the sides and the angle is:

c² = a² + b² - 2ab * cos(C)

Given: angle G = 72°, FG = 6

We can use the Law of Cosines to find the lengths of the other sides:

EF² = FG² + GE² - 2FG * GE * cos(G)

EF = √(6² + GE² - 2 * 6 * GE * cos(72))

FG² = EF² + GE² - 2EF * GE * cos(F)

FG = √(EF² + GE² - 2 * EF * GE * cos(66))

As we don't have any value for GE, we can't calculate the exact values, but as we know that the side opposite to the largest angle is the longest side of a triangle, so we can order the sides as follows:

EF < FG < GE

It means that side GE is the longest side of the triangle, followed by side FG, and side EF is the shortest side of the triangle.

What is a logarithm?

A logarithm is a mathematical function that calculates the power to which a given number (called the base) must be raised to produce a given value. The most common base used in logarithms is base 10, but logarithms can be defined with any base. If the base of a logarithm is not specified, it is assumed to be base 10. The logarithm of a number is represented by the symbol log.

The value of x in the equation logx = 2 can be found by solving for x. The logarithm of a number is the exponent that the base must be raised to in order to produce that number. So, in the equation logx = 2, x is equal to the base raised to the power of 2.

So,

logx = 2

x = 10^2

x = 100

if the base of the logarithm is not specified it is assumed to be base 10.

So, logx = 2 means x = 10^2 = 100

Hence, for logx = 2, the value of x would be 100.

The solutions are:

a) y = (lnx + 42 - ln7)/x

What are differential equations?
A differential equation is an equation that relates a function to its derivatives.

To verify that every member of the family of functions y=(lnx+C)/x is a solution of the differential equation x^2y' + xy = 1, we can substitute the function into the equation and see if it holds true for all values of x.

y=(lnx+C)/x

y'= (1/x - lnx - C)/x^2

x^2(1/x - lnx - C)/x^2 + x(lnx+C)/x = 1

(1 - xlnx - xC) + (lnx+C) = 1

lnx + C = 1/x

The equation holds true for all x, so it is a solution of the differential equation.

a) To find a solution of the differential equation that satisfies the initial condition y(7)=6, we can use the fact that y=(lnx+C)/x is a solution and plug in the initial condition.

y(7) = (ln7+C)/7 = 6

ln7 + C = 42

C = 42 - ln7

y = (lnx + 42 - ln7)/x

b) To find a solution of the differential equation that satisfies the initial condition y(6)=7, we can use the fact that y=(lnx+C)/x is a solution and plug in the initial condition.

y(6) = (ln6+C)/6 = 7

ln6 + C = 42

C = 42 - ln6

y = (lnx + 42 - ln6)/x

I need to understand quadratic graphs. eg. y=x^2 +2x -3

Answers

A quadratic graph is a type of parabolic graph that can be represented by the equation y = ax^2 + bx + c, where a, b, and c are constants and x is the variable. The graph of this equation is a parabola that opens either up or down, depending on the value of a.

The equation y = x^2 + 2x - 3 is an example of a quadratic graph. It can be written in the standard form of a quadratic equation as y = x^2 + 2x - 3, where a = 1, b = 2 and c = -3.

The x^2 term in the equation is known as the quadratic term, and it is responsible for the parabolic shape of the graph. The x term and the constant term, 2x and -3, respectively, determine the location of the vertex and the direction of the parabola.

The vertex of the parabola is the point where the parabola changes direction. It can be found by using the formula x = -b/2a, which in this case is x = -2/2 = -1 and y = f(-1) = -1.

The graph of y = x^2 + 2x - 3 is a parabola that opens upwards and the vertex of the parabola is (-1,-1)

In summary, a quadratic graph is a parabolic graph represented by the equation y = ax^2 + bx + c, where a, b, and c are constants. The x^2 term gives the parabolic shape to the graph, the x term and the constant term determine the vertex and the direction of the parabola respectively.

The study records the number of passengers arriving within any 1-hour time block. The data collected is then analyzed using a statistical technique called regression equation analysis, which is a method to estimate the strength and direction of the relationship between two or more variables.

The outcome or the result of the analysis is not provided in the given information.

Consumer Reports gave a report about the life (hours) of size AA batteries in toys. A total of 16 random toys were tested which gave a mean life of 3.58 hours with sample standard deviation of 1.85 hours. a. The packaging for the batteries claims that the AA batteries last around 5 hours in toys. Does the sample differ from the claim? a = .05 b. Would your answer change if a - .001? Explain.

Answers

a. To determine if the sample differs from the claim, we can use a hypothesis test. The null hypothesis is that the mean life of the AA batteries in toys is 5 hours, and the alternative hypothesis is that the mean life is different from 5 hours.

What does a math equation mean?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Using a t-test with a significance level of 0.05, we can calculate the t-statistic and the p-value.

The t-statistic is calculated as (mean - hypothesized mean) / (standard deviation / sqrt(sample size))

t = (3.58 - 5) / (1.85 / sqrt(16)) = -2.06

The p-value is the probability of getting a t-statistic as extreme or more extreme than the one we calculated, assuming the null hypothesis is true.

p-value = P(t < -2.06) = 0.048

Since the p-value is less than 0.05, we can reject the null hypothesis and conclude that the sample mean of 3.58 hours differs significantly from the claim of 5 hours.

b. The p-value is the probability of getting a t-statistic as extreme or more extreme than the one we calculated, assuming the null hypothesis is true. If we change the significance level to 0.001, the p-value would be less than 0.001, which would still be less than the new significance level. Therefore the conclusion would still be the same, the sample mean of 3.58 hours differs significantly from the claim of 5 hours.

However, it's worth mentioning that a lower significance level (0.001) would require a stronger evidence against the null hypothesis, therefore it would be more stringent in accepting the alternative hypothesis.

Fluffy laundry detergent reduced its regular size from 4.2 kg to 3.6 kg. The retail price dropped from $10.29 to $9.18. What was the percent change in the unit price?

Answers

Original Unit Price:

    $10.29 / 4.2 kg = $2.45/kg

New Unit Price:

    $9.18 / 3.6 kg = $2.55/kg

The price went up by $0.10/kg.  If we compare that (divide that) by the starting unit price of $2.45, we get:

       $0.10 / $2.45 ≈ 0.040816326530612

                              ≈ 4.0816326530612 %

Write the equation for the trend line in y=mx+b form.

Answers

Answer:

y=3/2x+86

Step-by-step explanation:

y=Mx+b

M is the slope and b is the y intercept. The slope of a line is rise/run, in this case 3/2 and the y intercept is where the line goes through the y axis which for this problem, is 86. So y=3/2x+86

Determine which of the lines, if any, are parallel or perpendicular. Explain. Line a passes through (2, 10) and (4,13). Line b passes through (4,9) and (6, 12) Line c passes through (2, 10) and (4,9). are parallel. The slopes are perpendicular to The slopes are

Answers

Line A is parallel to line B

We know, the slope of the line joining two points [tex](x_{1} ,y_{1} )[/tex] , [tex](x_{2} ,y_{2} )[/tex] is:

[tex]m = \frac{y_{2} - y_{1} }{x_{2}- x_{1}}[/tex]

Line A is passing through (2, 10) and (4,13).

The slope of line A

[tex]m_{1} = \frac{y_{2} - y_{1} }{x_{2}- x_{1}} = \frac{13 - 10}{4-2} =\frac{3}{2}[/tex]

Line B is passing through (4,9) and (6, 12)

The slope of line B

[tex]m_{2} = \frac{y_{2} - y_{1} }{x_{2}- x_{1}} = \frac{12 - 9}{6-4} =\frac{3}{2}[/tex]

Line C is passing through (2, 10), and (4,9).

The slope of line C

[tex]m_{3} = \frac{y_{2} - y_{1} }{x_{2}- x_{1}} = \frac{9- 10}{4-2} =\frac{-1}{2}[/tex]

We also know that if the slope of two lines is equal that is [tex]m_{1} = m_{2}[/tex] then the lines are parallel and

if the slope of the two lines has a relation [tex]m_{1} * m_{2} = -1[/tex] , the lines are perpendicular to each other.

Here, since the slope of lines A and lines B are equal.

Hence, line A is parallel to line B.
