Which is called vertex?

Answers

Answer 1

A vertex is a point where two or more curves, lines, or edges meet.

In geometry, vertex generally refers to an intersection point or a corner where lines, curves or edges meet. As a consequence of this definition, the point where two lines meet to form an angle called an included angle are considered vertices. Hence, the corners of triangle, polygons and polyhedral are vertices. For example, the lines of square or rectangle intersect at four corners which are called its vertices (which is the plural of vertex). Similarly, the vertex of curve(s) is where they intersect with each other or with its line of symmetry.

which is the equation of the line with a slope of 2 that goes through the point (1,2.5)

Answers

Answer:

y - 2.5 = 2(x - 1)

Step-by-step explanation:

Here given slope is 2 and the point through which the straight line passes is (1, 2.5)

Let the equation be y = mx + c where m and c represent slope and y intercept respectively.

We know the slope, so we input that in our equation

y = 2x + c ------- i

This straight line also passes through (1, 2.5)

Putting the values in place of x and y we get,

2.5 = (2X1) + c

⇒ 2.5 = 2 + c

⇒ c = 2.5 - 2

⇒ c = 0.5

Now, putting value of c in i, we get

y = 2x + 0.5 -------- ii

It can also be written as y - 2.5 = 2(x - 1) ------- iii

this equation and ii are same and you can verify that by simplifying iii, by multiplying 2 and then shifting the -2.5 from LHS to RHS

A line has a slope of 1 and passes through the point (8, –1) . What is its equation in slope -intercept form?

Answers

The slope-intercept form of a linear equation is given by the equation y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).

Given that the slope of the line is 1 and it passes through the point (8, –1), we can use the point-slope form of a linear equation to write the equation in slope-intercept form. The point-slope form is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Substituting the values given in the problem into the point-slope form, we get:

y - (-1) = 1(x - 8)

Expanding the right side and rearranging the terms, we get:

y + 1 = x - 8

y = x - 9

This is the equation of the line in slope-intercept form. The y-intercept is (-9, 0), which is the point at which the line crosses the y-axis.

Answers

fn is an integrable function on [a, b]. further, assume that the sequence (fn) converges uniformly to f on [a, b]. f is integrable on integral [a, b].

Let ε > 0. Since (fn) converges uniformly to f on [a, b], there exists an N such that |fn(x) - f(x)| < ε for all x ∈ [a, b] and all n ≥ N.

Since fn is integrable on [a, b], it follows that

∫a b|fn(x)|dx < ∞ for all n ≥ N.

We have

∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ∫a b|fn(x) - f(x)|dx

Since |fn(x) - f(x)| < ε, it follows that

∫a b|f(x)|dx ≤ ∫a b|fn(x)|dx + ε(b - a)

Since the right hand side is finite, it follows that ∫a b|f(x)|dx is finite. Hence, f is integrable on integral [a, b].

Suppose you are trying to learn the relationship between the price you charge for your product and the likelihood of purchase by individuals offered that price. You offer your product online and for one month have randomly posted prices between $10 and $30. Using data on purchases and prices, you get the following estimates for a linear probability model:
Purchasei=1.7−0.06×Pricei
You are interested in the effect of a $20 price increase (i.e., moving from the lowest price to the highest) on the likelihood of Purchase. Why is answering this question problematic using this model?

Answers

The issue with this model is that purchases with a cost of $30 appear to be negative, which is impractical in real-world situations.

This is due to the model's linear best fit line's potential for being inaccurate for the end points.

A linear probability model:

Purchasei = 1.7-0.06×pricei

For an increase in $20 in price,

Change in purchase = -0.06 × 20

change in purchase = -1.2

There would be 1.2 less purchase.

Purchase at price of $10 is:

Purchase 10= 1.7 ×0.06 × 10

Purchase 10 = 1.1

Purchase at price of $30 is:

Purchase 30 = 1.7 × 0.06 × 30

Purchase 30 = -0.1

This is the problem with this model that the purchases at price of $30 is coming as negative which is not possible in practical situation.

The circle equation in standard form is (X - 3)² + (Y - 1)² = 2²

How to change the circle equation into standard form?

We must transform the current polynomial to circle standard form:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

We will do so by completing the square, which produces a perfect square trinomial that can be factored into a square binomial in the form of the circle standard form.

According to the given question:

Equation of circle in polynomial form is X²+ Y²- 6X - 2Y + 6 = 0

Converting to standard form using completing the square method

X²+ Y²- 6X - 2Y + 6 = 0

(X² - 6X) + (Y² - 2Y) = -6

(X² - 6X + 9) + (Y² - 2Y + 1) = -6 + 9 + 1

(X - 3)² + (Y - 1)² = 4

(X - 3)² + (Y - 1)² = 2²

Answers

The value of y is 4.

What is The value of y?

Generally, To find the value of y in the expression [0 (3z-9) (y-1)], we need to isolate y. To do this, we can start by combining like terms:

[-1(4x-2) -5] [-1 2 -5] [0 (3z-9) (y-1)] [0 3 2]

Becomes:

[-4x + 2 - 5] [0 3 2]

Then we can rearrange the terms to get:

[-4x - 5 + 2] [0 2 + 3]

This simplifies to:

[-4x - 3] [5]

Finally, we can isolate y by dividing both sides by 2:

[-4x - 3] / 2 = 5 / 2

This gives us:

y = (5/2) + 3/2

Simplifying, we find that y = 4.

Therefore, the value of y in the expression [0 (3z-9) (y-1)] is 4.

The strength of the field is shown by the distance between the lines; the closer they are to one another, the stronger the field.

In this scenario, the field weakens as we travel away from the charge because the distance between the lines widens (it actually obeys an inverse square law,

The electric field, which is pointed away from the core charge, is indicated by the direction of the lines.

This is due to the fact that a positive test charge would be repelled away from the electric field if it were placed there because the direction of the electric field corresponds to the direction of the force that a positive test charge would experience when immersed in the electric field.

f(x) >0 for x>4

So, the function is increasing in x>4

Similarly, If x <-1

f(x) >0 for  x <-1

So, function is increasing in x <-1

If -1<x<3/2

f(x)<0 for -1<x<3/2

So, function is decreasing in -1<x<4

If 3/2<x<4

f(x)>0 for 3/2<x<4

So, the function is increasing in 3/2<x<4

From the graph too, we can see the behavior of the given function

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function.

Linear functions have constant first differences.

Here,  if a and b is the first and second term.

Then the first difference is b-a.

Quadratic functions have constant second differences.

Let the first differences are:

b-a = m, c-b = n

Then the second difference is n-m.

Exponential functions have a constant ratio.

The ratio of first term and second term is b/a.

Here, from the table;

y₂-y₁ = 0.4 - 0.9 = -0.5 = m₁

y₃-y₂ = 0.1 - 0.4 = -0.3 = m₂

y₄-y₃ = 0 - 0.1 = -0.1 = m₃

y₅-y₄ = 0.1 - 0 = 0.1 = m₄

y₆-y₅ = 0.4 - 0.1 = 0.3 = m₅

From the first differences, we have no idea about the function property.

So, the second differences:

m₂ -  m₁ = -0.3 + 0.5 = 0.2

m₃ - m₂ = -0.1 + 0.3 = 0.2

m₄ - m₃ = 0.1 + 0.1 = 0.2

m₅ - m₄ = 0.3 - 0.1 = 0.2

Here, the second differences are constant 0.2.

And the common ratio is varying.

So, quadratic functions have constant second differences.

And the quadratic function is y = x² / 10.

Therefore, the given function is a quadratic function.

For the functions f(t) = et and g(t) = e-6t, defined on 0 Le t Le infinity, compute f * g in two different ways: By directly evaluating the integral in the definition of f * g. (f * g) (t) = dw = By computing L-1 {F(s)G(s)} where F(s) = L{f(t)} and G(s) = L{g(t)}. (f * g)(t) = L-1 {F(s)G(s)} = L-1{ }

Answers

The value of the expression (f * g) by using two ways that is by direct integral and by Laplace transform is equal to (1/2)e^t/(1-t) - (1/2)e^t/(1+t) + C.

To compute the convolution of f(t) and g(t) by directly evaluating the integral in the definition of the convolution, we have:

(f * g)(t) = ∫f(w)g(t-w)dw

Substituting in the expressions for f(t) and g(t), we have:

(f * g)(t) = ∫e^w*e^(-6)(t-w)dw

This integral can be evaluated as follows:

(f * g)(t) = ∫e^(-5w)dw

(f * g)(t) = (-1/5)e^(-5w) + C

(f * g)(t) = (-1/5)e^(-5w) + C

To compute the convolution of f(t) and g(t) by computing the inverse Laplace transform of the product of the Laplace transforms of f(t) and g(t), we have:

F(s) = L{f(t)} = ∫f(t)e^(-st)dt = ∫e^t*e^(-st)dt = 1/(s-1)

G(s) = L{g(t)} = ∫g(t)e^(-st)dt = ∫e^(-6t)*e^(-st)dt = 1/(s+6)

Therefore,

F(s)G(s) = (1/(s-1))(1/(s+6)) = 1/(s^2-1)

To find the inverse Laplace transform of F(s)G(s), we use the following formula:

L^-1{F(s)G(s)} = ∫F(s)G(s)e^st ds

Substituting in the expression for F(s)G(s), we have:

L^-1{F(s)G(s)} = ∫(1/(s^2-1))e^st ds

This integral can be evaluated as follows:

L^-1{F(s)G(s)} = (1/2)e^st/(s-1) - (1/2)e^st/(s+1) + C

L^-1{F(s)G(s)} = (1/2)e^st/(s-1) - (1/2)e^st/(s+1) + C

Thus, the convolution of f(t) and g(t) can be computed either by directly evaluating the integral in the definition of the convolution or by computing the inverse Laplace transform of the product of the Laplace transforms of f(t) and g(t). In both cases, the result is:

(f * g)(t) = (1/2)e^t/(1-t) - (1/2)e^t/(1+t) + C

The first vivarium of such a kind, on anythinglike an large scale, was that opened to public exhibition in the Regent's Park Zoological Gardens. Many naturalists had previously madeexperiments to ascertain some certain method of preserving aquatic animals in a living and healthy state. The vivarium, which is the result of thoseexperiments, may be considered as an imitation of the means employed by nature herself in the preservation of the various forms of animal andvegetable life which populate the oceans and the streams.The vivarium is, therefore, no recent or sudden discovery, but a growth of years. Its present perfection is the fruit of many patient investigations, trials,disappointments, and determinations to achieve success.The term vivarium applies to any collection of animals-to a park of deer, a rabbit warren, a menagerie, or even a traveling show containing anasthmatic lion, a seedy cockatoo, and a pair of snakes that are hourly stirred up with a long pole. For this reason, such a term could never convey thevery special idea of a vessel containing such specimens as form the stock of the aquarium. When this was felt, the prefix aqua was added, to conveythe idea of the water medium in which the specimens are immersed.This invention led us to the word aqua-vivarium, a compound of too clumsy a character to remain long in use. It is the water that gives the collectionits special character, and water always reminds us of old Aquarius, who treats us to an annual drenching from his celestial watering pot. Naturallypeople wanted to give the place where they kept their confined watery companions Aquarius' name an aquarium. The term that referred to oldAquanus stuck. Since it is better to follow than oppose what people want to call something, we'll leave the philological part of the question to theintellectuals and adopt aquarium as the name for our collection of underwater creatures What were the reasons for religious migration to specific colonies?; Why was religious freedom so important to the colonies?; What 3 colonies were founded in an attempt to escape religious persecution?; What were the early British settlers fleeing from?
