Find the orthogonal trajectories for the family of curves. (Enter your solution in the form F(x, y) = C or y = F(x, C) where C is a needed constant.) 3x^2 − y^2 = C.

Answers

Answer 1

The orthogonal trajectories for the family of curves 3x^2 − y^2 = C are circles with the equation x^2 + y^2 = C/3.

To find this, we can take the derivative of the original equation 3x^2 − y^2 = C with respect to x, which will give us 6x. Then, we can take the negative reciprocal of this derivative, which is -1/6x. This is the slope of the orthogonal trajectories.

We then can use the point-slope form of a line to get y - y1 = -1/6x (x - x1). Since the slope of the orthogonal trajectories is always -1/6x, we can just set the equation y - y1 = -1/6x (x - x1) equal to 0 and solve for x to get x1 = -y1/6.

We can then plug this value back into the point-slope equation to get y - y1 = -1/6(-y1/6) (x - (-y1/6)), which simplifies to y - y1 = y1/6 + x. Now, if we let y1 = -C/3, then we get y - (-C/3) = C/6 + x, which can be rewritten as x^2 + y^2 = C/3.

Therefore, the orthogonal trajectories for the family of curves 3x^2 − y^2 = C are circles with the equation x^2 + y^2 = C/3.

In the xy-plane, line m passes through the origin and is perpendicular to the line 6x+y=h, where h is a constant. If the two lines intersect at point (p, p+2), what is the value of p?

Answers

Using slope intercept equation the value of p is -2.4 .

What is slope intercept equation?

When the slope of the line being studied is known, and the provided point is also the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).   It provides both a slope and an intercept, which is why the form is known as the slope-intercept form.

Let’s call line m y’ and we can deduce that y’ = ax where a is the slope of line y’. (In the standard line equation, y = mx + b, b is the y intercept which, in the case of line m, is zero since it passes through the origin (0,0).)

Then name the 2nd line y’’ = -6x + h

When straight lines are perpendicular, their slopes are negative inverses. So the slope of line y’, which I’ve called a, must equal +1/6

Now we know that y’ = (1/6)x and y’’ = -6x + h

If the lines intersect at a point (x , y) which we are told is (p, p+2), then at that point y’ = y’’, or p+2 = (1/6) and p = -6(p+2) + h.

From this we can solve for p,

=> p - p/6 = -2=> (5/6)p = -2 or

=>p = -12/5 = -2.4

Now we know that the intersection point (p,p+2) is (-2.4, -0.4)

Hence the value of p is -2.4 .

Every vertex of a graph can be assigned an integer in {1, 2, ..., d1} so that no two adjacent vertices are assigned the same integer.

We can use induction to show that every vertex of a graph can be assigned an integer in {1, 2, ..., d1} so that no two adjacent vertices are assigned the same integer. Let G be a graph with d vertices, and assume that the result is true for all graphs with fewer than d vertices. Consider any vertex v in G and let N(v) be the set of neighbours of v. Since |N(v)| < d, by our induction hypothesis, there is an assignment of the integers 1,2, ..., d−1 to the vertices in N(v) so that no two adjacent vertices are assigned the same integer. Now assign the dth integer, i.e., d, to v and we are done. By our induction hypothesis, this assignment works for all graphs with d vertices. Thus, by induction, every vertex of a graph can be assigned an integer in {1, 2, ..., d1} so that no two adjacent vertices are assigned the same integer.

For example, you can select the coordinates of the black point (plus symbol) you placed on the graph previously to see that the intersection of the curves occurs at the point representing a quantity of ________ boxes.

Answers

The black point (plus symbol) selected on the graph has coordinates of (4, 0.4).

This point represents the intersection of the two curves on the graph. To calculate the quantity of boxes represented by this point, we can use the equation y=mx+b, where m is the slope of the line, x is the x-coordinate, and b is the y-intercept.

In this case, the slope of the line is -2, the x-coordinate is 4, and the y-intercept is 0.4. We can substitute these values into the equation to solve for the quantity of boxes, which would be: y=-2x+0.4. Plugging in the x-coordinate of 4, we would get: 0.4=-2(4)+0.4, which simplifies to 0.4=-8. Solving for y, we would get 8 boxes. Therefore, the point (4, 0.4) on the graph represents a quantity of 8 boxes.

What do the triangular theorems state?

The positions of the theorems are as follows:

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse). This can be written as a^2 + b^2 = c^2, where c is the length of the hypotenuse and a and b are the lengths of the legs.

The Law of Cosines states that in any triangle, the square of the length of a side is equal to the sum of the squares of the lengths of the other two sides, minus twice the product of the length of one side times the cosine of the angle between the other two sides. This can be written as c^2 = a^2 + b^2 - 2ab * cos(C)

The Law of Sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. This can be written as a/sin(A) = b/sin(B) = c/sin(C)

What is the constant of proportionality?
y= 1/4 x= 3/8

Answers

Answer:

y = 1/4x

Step-by-step explanation:

Proportional Relationships:

A proportional relationship is similar to a linear relationship, with one distinction, it's y-intercept is equal to zero, so it can be expressed in the form: [tex]y=kx[/tex], where "k" is some constant. More specifically, when we divide y by x, we always get a constant amount, denoted as "k": [tex]\frac{y}{x}=k[/tex].

Using this knowledge, we can kind of immediately tell it's [tex]y=\frac{1}{4}x[/tex] as it's the only one in the form: [tex]y=kx[/tex], but let's look at why [tex]x=\frac{3}{8}[/tex] is not a proportional relationship.

It's important to note that [tex]x=\frac{3}{8}[/tex] is a vertical line, since the x value is constant while the y value varies. This means "y/x" cannot be constant, since "y" changes, except what it's being divided by will remain the same, equal to 3/8.

let and let have critical numbers -2, 0, and 2. use the second derivative test to determine which critical numbers, if any, give a relative maximum

Answers

According to the second derivative test, whether or not there is a relative maximum or minimum at a crucial number depends on the sign of the second derivative. According to the second derivative test, in this situation, -2 and 0 result in a relative minimum, whereas 2 results in a relative maximum.

To ascertain if a crucial number belongs to a relative maximum or relative minimum, one can utilise the second derivative test. Calculate the function's second derivative before using the test. After that, calculate the second derivative at the threshold value. The critical number relates to a relative maximum if the second derivative is negative. The crucial number corresponds to a relative minimum if the second derivative is positive. Specifically, At -2 and 0, when the second derivative is negative, there is a relative minimum. The crucial number 2 corresponds to a relative maximum since the second derivative is positive at that value.

What is Systematic sampling?

Systematic sampling is a method of sampling where the sample is selected using a fixed interval, rather than using random sampling. The sampling process begins by selecting a random starting point in the population and then selecting every kth element from the population.

For example, if the population has 100 elements and k=10, every 10th element would be selected for the sample.

Dividing the population into groups, and then using simple random sampling to identify a proportionate number of individuals from each group is a method called stratified sampling.

It is important to note that systematic sampling can be vulnerable to sampling bias if the sampling interval is not chosen carefully and the population is not randomly ordered, because in that case, it will not be a truly random sample.

The age of maria in year X = (X - 2000)

The age of her mother in year X, = (X - 1975)

The age of her father in year X, = (X - 1970)

Sum of their age,

100 = (X - 2000) + (X - 1975) + (X - 1970)

100 = 3X - (2000 + 1975 + 1970)

100 = 3X - 5945

3X = 5945 + 100

3X = 6045

X = 2015

Hence option (a) is correct.

Simplify 5/8x+1/2(1/4x+10)

Answers

The simplification 5/8(x )+ 1/2 ( 1/4( x) +10) is 3/4(x) + 5

What is simplification of fractions?

The word simplify means to make something easier to do or understand. So, reducing or simplifying fractions means we make the fraction as simple as possible. We do this by dividing the numerator and the denominator by the largest number that can divide into both numbers exactly.

For example 25/100 can be simplified by cutting down 25 and 100 by their common factor which is 25.

25/100 = 1/4

⅝(x) + 1/8(x) + 5

= 6/8(x) +5

= 3/4(x) + 5

therefore the simplification of 5/8(x )+ 1/2 ( 1/4( x) +10) is 3/4(x) + 5

Determine the measure of Angle B in the triangle below. thank you

Answers

Answer:

55°

Step-by-step explanation:

2x + 5 + 2x + 3x = 180   Combine like terms  The sum of the interior angles of a triangle is 180

7x + 5 = 180  Subtract 5 from both sides

7x + 5 - 5 = 180 - 5

7x = 175  Divide both sides by 7

[tex]\frac{7x}{7}[/tex] = [tex]\frac{175}{7}[/tex]

x = 25

Substitute 25 for x

2x + 5

2(25) + 5

50 + 5

55 is the measurement of angle B

Write the equation of the line that passes through the point (0, 1) and is perpendicular to the line y=1/5x+2

Answers

Answer:

the requisite equation for the given question is y=−5x

Step-by-step explanation:

firstly, select the coordinates (0, 0) through which the perpendicular line will cross (0,0)

then, locate the slope when y=15x+2y=15x+2.

The slope is 1/5 when expressed in the slope-intercept format.

therefore, m=1/5

since, a perpendicular line's equation must have a slope equal to the inverse reciprocal of its initial slope.

therefore, [tex]m_{perpendicular}[/tex]=−1/(1/5)

To determine the slope of the perpendicular line, simplify 1/(1/5).

[tex]m_{perpendicular}[/tex]=−5

By using point-slope method, determine the perpendicular line's equation.

y+0=−5.(x+0)

Solve for y.

y= -5x + 0

y=−5x

hence, the answer for the question is y=-5x
