Answer:
30,40,50
Step-by-step explanation:
We use the Pythagorean theorem to find out if they would be sides of a right triangle
the Pythagorean theorem states that the two shorter sides squared added together equal the longest side square
for 30, 40 , 50
\(30^2=900\\40^2=1600\\1600+900=2500\\50^2=2500\\2500=2500\)
2500=2500 therefore that is the correct answer

how do you create a line ?
you mark 2 points, take a ruler and draw a line through both points (and extend the line beyond the points as far as the chart goes).
how do you find points ?
you think about a nice value for x (really, any value on the x-axis of the chart is OK) and then calculate y.
you mark the point at this x, y coordinates.
you know, the x-axis is the horizontal coordinate line, and the y-axis is the vertical coordinate line.
so, I would pick x =0. that gives us y = 0 + 0.5 = 0.5.
and maybe x = 2. that gives us y = 2 + 0.5 = 2.5
so, you have (0, 0.5) and (2, 2.5) as points.
and then simply do as described above.
there is an edge between the vertices representing cities if there is an interstate highway between them?
Yes, an edge exists between the vertices representing cities if there is an interstate highway between them.
In a graph representation of cities and interstate highways, the cities are represented by vertices, and the interstate highways are represented by edges. An edge connecting two vertices signifies that there is a direct connection between the cities through an interstate highway.
To determine whether an edge exists between two vertices representing cities, you need to check if there is an interstate highway connecting them. This can be done by consulting a map or transportation database that provides information about the interstate highways connecting different cities.
If you find that there is an interstate highway connecting two cities, you can add an edge between the corresponding vertices in the graph representation. This edge represents the direct connection between the cities through the interstate highway. Conversely, if there is no interstate highway connecting two cities, there will be no edge between the corresponding vertices in the graph representation.
Remember that the presence of an edge between two vertices represents the existence of an interstate highway between the cities they represent in the graph.

Find two unit vectors orthogonal to both (3 , 2, 1) and (- 1, 1, 0 )
The two unit vectors that are orthogonal to both (3, 2, 1) and (-1, 1, 0) are (2/√14, -3/√14, 1/√14) and (1/√2, 1/√2, 0).
To calculate the first unit vector, take the cross product of the two vectors to find the vector that is perpendicular to both.
The vector (2, -3, 1) is the result of the cross product. To normalize the vector to a unit vector, divide each component of the vector by the magnitude, which is the square root of 14.
Therefore, the normalized vector is (2/√14, -3/√14, 1/√14).
To calculate the second unit vector, add the two original vectors together and then normalize the result by dividing each component by the magnitude, which is the square root of 2.

Solve yy' +x =3 √(x^2+ y2) (Give an implicit solution; use x and y.)
The implicit solution to the differential equation yy' + x = 3 √(x^2 + y^2) is given by x^2 + y^2 = (x^2 + y^2)^(3/2) + C, where C is a constant of integration.
To solve the given differential equation, we'll rewrite it in a standard form. Dividing both sides of the equation by √(x^2 + y^2), we have yy'/(√(x^2 + y^2)) + x/(√(x^2 + y^2)) = 3. Notice that the left side of the equation represents the derivative of √(x^2 + y^2) with respect to x. Applying the chain rule, we obtain d(√(x^2 + y^2))/dx = 3. Integrating both sides with respect to x, we get √(x^2 + y^2) = 3x + C, where C is a constant of integration.
Squaring both sides of the equation yields x^2 + y^2 = (3x + C)^2. Simplifying further, we have x^2 + y^2 = 9x^2 + 6Cx + C^2. Rearranging the terms, we obtain x^2 + y^2 - 9x^2 - 6Cx - C^2 = 0, which can be rewritten as x^2 + y^2 = (x^2 + y^2)^(3/2) + C. Thus, this equation represents the implicit solution to the given differential equation.

You place a bet of k dollars and flip a fair coin once: if the coin comes up heads, you get your bet back plus a payout of k dollars. If the coin comes up tails, you lose your bet. What is the expected value of this game
The expected value of this game is 0.5k - 0.5k, which simplifies to 0. This means that on average, you neither win nor lose money in the long run if you keep playing this game. However, it's important to note that in any individual round of the game, you could either win k dollars or lose k dollars. The expected value of this game is (1/2)k dollars.
To calculate the expected value of this game, we need to consider the probabilities and outcomes for each possible result of the coin flip:
1. If the coin comes up heads (probability = 1/2), you win k dollars in addition to getting your k dollars back. The total outcome for heads is 2k dollars.
2. If the coin comes up tails (probability = 1/2), you lose your k dollars. The total outcome for tails is -k dollars.
Now, we can calculate the expected value using the formula:
Expected Value = (Probability of heads * Outcome for heads) + (Probability of tails * Outcome for tails)
Expected Value = (1/2 * 2k) + (1/2 * -k)
Expected Value = k - (1/2)k
Expected Value = (1/2)k
The expected value of this game is (1/2)k dollars.

the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).
n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).
To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.
Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.
Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.
Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

4. Recursively defined sets ( 3 points) Give a recursive definition of the set below. The set of positive integer powers of 5 . 5. Divisibility (4 points) Prove that if a∣b and b∣a, then a=b or a=−b.
4. We start with the base case of \(5^0 = 1\) and recursively generate the next element in the set by multiplying the previous element by \(5\).
5. if a divides \(b\) and \(b\) divides \(a\), either a equals \(b\) or \(a\) equals negative \(b\).
4. The recursive definition of the set of positive integer powers of 5 can be expressed as follows:
Base case: \(5^0 = 1\) is in the set.
Recursive step: If n is in the set, then \(5^(n+1)\) is also in the set.
Using this definition, we start with the base case of \(5^0 = 1\)and recursively generate the next element in the set by multiplying the previous element by \(5\).
5. To prove that if a divides \(b\) and \(b\)divides \(a\), then a equals \(b\) or \(a\) equals negative \(b\), we can use the definition of divisibility.
Assume that \(a\) divides \(b\), denoted as \(a | b\) , and \(b\) divides \(a\), denoted as \(b | a.\)
By definition, if a divides b, there exists an integer k such that b = ak.
Similarly, if \(b\) divides \(a\), there exists an integer m such that \(a = bm.\)
Substituting the expression for\(b\) in terms of \(a\), we have \(bm = ak.\)
Dividing both sides by b (since b is nonzero), we get m = a/b.
Since \(m\) is an integer, \(a/b\) must be an integer, which means \(a\) is divisible by \(b\).
If \(a/b\) is an integer, it implies that \(b/a\)is also an integer, which means \(b\) is divisible by \(a\).
Therefore, if \(a\) divides \(b\) and \(b\) divides \(a\), it follows that \(a/b\) and \(b/a\) are both integers.
If \(a/b = m\) and \(b/a = k\), then we have \(a = bm\) and\(b = ak.\)
\(If m = k = 1, then $a = b.\)
\(If m = k = -1, then a = -b.\)
Therefore, if \(a\) divides \(b\) and \(b\) divides \(a\), either \(a\) equals \(b\) or \(a\) equals negative \(b\).

When Omar does not have a common factor while factoring a polynomial, he should consider regrouping terms, factoring out a common factor, or adjusting signs to simplify the expression. The absence of a common factor does not necessarily mean the polynomial is prime.
If Omar noticed that he does not have a common factor when factoring a polynomial, there are a few possible next steps to consider. It is important to note that the absence of a common factor does not necessarily mean that the polynomial is prime.
One option for Omar is to go back and regroup the terms in step 1, as (3x³ – 15x²) – (4x + 20). By rearranging the terms, he may be able to identify a common factor or a different factorization approach.
Another possibility is for Omar to factor out a common factor from the first expression in step 2. He can examine the terms in the expression and determine if there is a factor that can be pulled out.
It is also worth considering whether Omar needs to factor out a negative from one of the groups so that the binomials become the same. This step can help simplify the expression and make the factoring process easier.
Overall, Omar should explore different factorization strategies, regroup terms if necessary, and look for common factors or patterns to continue factoring the polynomial. The absence of a common factor does not necessarily imply that the polynomial is prime.

The main answer is, tan A + cot A + csc A = -8.9394.
Given A= 86.0, B=15.0, and C= 24.0;To find, tanecot + csc
We know that, cos = -0.10cos A = -0.10
To find sin A; we use the identity;sin^2A + cos^2A = 1
Substituting the value of cos A; we get sin A as;sin^2A + (-0.10)^2 = 1sin^2A = 0.99sin A = ±√0.99
Given sin A is in Quadrant II; hence it is positive,sin A = √0.99sin A = √(9/10)^2sin A = 9/10
Similarly, we know that Tan A is negative in Quadrant II and III.
Tan A = -√(1-cos^2A)/cosA= -√(1-0.01)/(0.10)= -√(99/100)/(10/100)= -√99= -9.95
Given Tan A is negative and Sin A is positive; we know that Cos A is negative and located in Quadrant II; Thus we get Cos A = -√(1- sin^2A)Cos A = -√(1-0.99)Cos A = -√0.01= -0.10
From here, we can find sec A and cot A as;Sec A = -1/Cos A= -1/(-0.10)= 10Cot A = 1/Tan A= 1/(-9.95)= -0.1005Cosec A = 1/Sin A= 1/(9/10)= 1.1111tan A + cot A + csc A= -9.95 - 0.1005 + 1.1111= -8.9394

In 7 years, the population of the town will reach 24600.
How many years will it take for the population to 24600?Formula for population growth can be expressed as;
N = N₀ × e^(rt)
Where N is the future population, N₀ is the initial population, t is time and r is rate of growth.
Given the data in the question;
Initial population N₀ = 15,000 Future population N = 24,600Rate of growth r = 3%Time t = ?First, convert the rate from percent to decimal.
Growth rate r = 3%
Growth rate r = 3/100
Growth rate r = 0.03
Now, plug the given values into the above population growth formula and solve for t.
N = N₀ × e^(rt)
t = ln( N/N₀ ) / r
t = ln( 24600 / 15000 ) / 0.03
t = 17 years.
