B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

Yes, Dijkstra's algorithm can find the shortest paths in a directed acyclic graph (DAG). Dijkstra's algorithm is a popular algorithm used to solve the single-source shortest path problem in graphs with non-negative edge weights.

In a DAG, there are no cycles, meaning there are no paths that loop back to the same node. This absence of cycles ensures that there are no negative weight cycles that would cause the algorithm to fail. Since Dijkstra's algorithm relies on non-negative edge weights, it works perfectly fine in a DAG.

When applied to a DAG, Dijkstra's algorithm will efficiently compute the shortest paths from a given source vertex to all other vertices in the graph. It iteratively explores the graph, updating the distances to each vertex until the shortest paths to all vertices have been determined.

Therefore, if you have a directed acyclic graph and you want to find the shortest paths from a source vertex to all other vertices, you can confidently use Dijkstra's algorithm to achieve that.

Answer: PROFITS After Take Two began renting DVDs at their video store, business soared. Between 2000 and 2005, profits increased at an average rate of $9,000 per year. Total profits in 2005 were $45,000. If profits continue to increase at the same rate, what will the total profit be in ...

The estimated proportion raise in salary for an employee using the given fraction is equal to $1,250.

The fraction of $36,000 which is $45,000 is

= $45,000 / $36,000

= 1.25

It represents  $45,000 is 1.25 times more than $36,000.

Estimate the raise is,

Use proportion and calculate percentage increase in salary,

(Proportion of raise) = (Proportion of salary increase)

Let x be the raise for an employee making $45,000

$x / $1,000 = $45,000 / $36,000

Simplify it to get the value of x we have,

⇒x = (1.25) × $1,000

⇒x = $1,250

Therefore, the raise for an employee estimated salary using ratio and proportion is equal to $1,250.

Based on the chi-square test, there is no significant evidence to suggest that the die is not balanced.

We have,

To determine if the die is balanced, we can perform a chi-square test of goodness of fit.

The null hypothesis is that the die is balanced, and the alternative hypothesis is that the die is not balanced.

First, let's calculate the expected frequencies for each outcome assuming the die is balanced. Since there are 180 tosses in total, each outcome is expected to have an equal probability of 1/6.

Expected frequency for each outcome

= (Total tosses) x (Probability of each outcome)

Expected frequency for each outcome = (180) x (1/6)

Expected frequency for each outcome = 30

Now, we can calculate the chi-square test statistic using the formula:

χ² = Σ [(Observed frequency - Expected frequency)² / Expected frequency]

Let's calculate the chi-square test statistic:

χ² = [(28 - 30)² / 30] + [(36 - 30)² / 30] + [(36 - 30)² / 30] + [(30 - 30)² / 30] + [(27 - 30)² / 30] + [(23 - 30)² / 30]

χ² = [(-2)² / 30] + [(6)² / 30] + [(6)² / 30] + [(0)² / 30] + [(-3)² / 30] + [(7)² / 30]

χ² = 4/30 + 36/30 + 36/30 + 0/30 + 9/30 + 49/30

χ² = 134/30

χ² ≈ 4.467

Next, we need to compare the calculated chi-square value to the critical chi-square value at a significance level of 0.01 and degrees of freedom equal to the number of outcomes minus 1 (6 - 1 = 5).

Looking up the critical chi-square value in a chi-square distribution table with 5 degrees of freedom and a significance level of 0.01, we find it to be approximately 15.086.

Since the calculated chi-square value (4.467) is less than the critical chi-square value (15.086), we fail to reject the null hypothesis.

Therefore, we do not have sufficient evidence to conclude that the die is not balanced at a 0.01 level of significance.

Thus,

Based on the chi-square test, there is no significant evidence to suggest that the die is not balanced.

The given differential equation y x²y² = x² is a nonlinear and not separable differential equation, which corresponds to option (D).

A linear differential equation can be written in the form dy/dx + P(x)y = Q(x), where P(x) and Q(x) are functions of x. In this equation, the term x²y² makes it nonlinear.

A separable differential equation can be written in the form g(y)dy = f(x)dx, where g(y) and f(x) are functions of y and x, respectively. However, in the given equation, we cannot separate the variables y and x to obtain such a form.

To solve this particular differential equation, one approach is to rewrite it in a more manageable form. Let's rearrange the terms:

x² = y/(x²y²)

Now, we can multiply both sides by (x²y²) to eliminate the denominator:

x²(x²y²) = y

This equation is still nonlinear but can be used to find a particular solution for y given a specific initial condition.

The power series solution of the differential equation about x0 = 1 has a radius of convergence of 1.

To find the minimum radius of convergence R of power series solutions about the ordinary point x0 = 1 for the given differential equation, we need to use the Cauchy-Hadamard formula. The formula states that the radius of convergence R is given by:

R = 1/lim sup(|an|)^(1/n)

where an is the nth coefficient of the power series solution.

First, we need to find the power series solution of the differential equation about x0 = 1. We can assume that the solution is in the form of a power series:

y(x) = ∑ an (x-1)^n

We can differentiate this power series to find the derivatives needed to substitute into the differential equation. After substituting and simplifying, we get:

∑ (n+2)(n+1)an (x-1)^n + ∑ (n+1)an (x-1)^n + 4∑ an (x-1)^n = 0

Next, we need to find the coefficients an. We can do this by equating the coefficients of each power of (x-1) to zero. The first few coefficients are:

a0 = y(1)

a1 = y'(1)

a2 = y''(1)/2!

Substituting these coefficients into the formula for R, we get:

R = 1/lim sup(|(n+2)(n+1)/2!|^(1/n) + |(n+1)/1!|^(1/n) + |4/0!|^(1/n))

Taking the limit as n approaches infinity, we get:

lim sup(|(n+2)(n+1)/2!|^(1/n) + |(n+1)/1!|^(1/n) + |4/0!|^(1/n)) = 1

Therefore, the minimum radius of convergence R is:

R = 1/1 = 1

The measure of DA is 20 cm, the measure of EG is 12 cm and the measure of GC is 18 cm.

The theorem states if a transversal makes equal intercepts on three or more parallel lines, then any other line cutting them will also make equal intercepts. It means that given any three mutually perpendicular lines, a line passing through them forms intercepts in the corresponding ratio of the distances between the lines.

Here, EG = GA - AE

= 36-24

= 12 cm

Here, ΔADE is similar to ΔAGF

Now, AE/GA = AD/FA

⇒ 24/36 = AD/(AD+10)

⇒ 24 (AD+10) = 36AD

⇒ 24AD+240 = 36AD

⇒ 12AD =240

⇒ AD =20 cm

Here, ΔAGF is similar to ΔABC

Now, 30/45 = 36/AC

⇒ 30AC = 36×45

⇒ AC = 54 cm

So, GC = 54-36 = 18 cm

Therefore, the measure of AD is 20 cm, the measure of EG is 12 cm and the measure of GC is 18 cm.
