A'(1/2, 1/2), B'(3/4, 3/2), C'(1, 1/2) are the coordinates of the image after dilation.

Given,

Triangle ABC is dilated with a scale factor 2 at the origin.

We have to find the coordinates of the image;

Dilation;

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size.

Here,

The vertices of the triangle;  A(1, 1), B(1.5, 3), C(2, 1).

After the dilation of a scale factor 2, the new point;

A'(1/2, 1/2), B'(3/4, 3/2), C'(1, 1/2).

That is,

The coordinates of the image after dilation is, A'(1/2, 1/2), B'(3/4, 3/2), C'(1, 1/2).

Graph is negative and increasing in the interval x = - to x = a

A graph is included in the question in this case.

If the graph of any function is moving downward over a specific time interval, we know that. Function then starts to decline during that period.

If the graph of any function is rising during a specific interval. Function then increases throughout that specific time period.

A graph is positive when it is oriented above the horizontal axis.

It can be seen in the accompanying graph that the function's graph is below the x-axis between the values of x = - to x = a as it is oriented below the horizontal axis and graph is increasing

The sum of all possible values of N is 336.

What is an integer?

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers.

Here, we have

Let the three integers be a, b, and c.

N = abc = 6(a + b + c) and c = a + b.

Then N = ab(a + b) = 6(a + b + a + b) = 12(a + b).

Since a and b are positive, ab = 12

so {a, b} is one of {1, 12}, {2, 6}, {3, 4}

a + b is one of 13, 8, 7

N is one of 12× 13 = 156, 12× 8 = 96, 12×7 = 84

156 + 96 + 84 = 336.

Hence, the sum of all possible values of N is 336.

DSA is only used for signature purposes but RSA is used for cryptographic purposes.

But somehow DSA uses discrete logarithms for Encryption and in RSA long-term calculations are used which is more secure as compared to DSA.

Now while signing messages with DSA leads to a more time and more memory-consuming process because at every point the message is signed. So the verification of signatures gets complicated.

But in the case of RSA, the calculations are high, but they consume less memory and less need for verification. Because of large calculations, RSA is much slower than DSA.

There are infinitely many solutions to an equation with two variables.

We know that an equation is a mathematical statement that contains equal symbol between two mathematical expressions.

In this question need to solve  an equation with x and y in one equation.

Consider an equation with two variables: 5x + y = 8

If we solve given equation for x then it would be,

5x + y = 8

5x + y - y = 8 - y

5x/5 = (8 - y)/5

x = (8 - y)/5

for any arbitrary real value value of y we can find the value of x.

This means there are infinitely many solutions.

If we solve given equation for y then it would be,

5x + y = 8

5x + y - 5x = 8 - 5x

y = 8 - 5x

for any arbitrary real value value of x we can find the value of y.

The probability that a postdated cheque is forged is 0.8  .

In the question ,

it is given that ,

there is 1 cheque forged in 10000 cheques.

the percent of postdated cheques = 5% ,

So , the number of Post-dated cheque = 0.05*10,000 = 500

the percent of cheques that the postdated cheque is forged is = 80%

the number of Forged cheque that are post-dated = 0.8*500 = 400

So , Probability (post-dated check is forged) = (Forged check that are post-dated)/(post dated checks)

Substituting the values ,

we get ,

The situations represented by 25/9 are "Melanie equally shares 25 meters of paper to create 9 banners" and "Joe makes 9 equal servings from a 25 ounce bag of peanuts".

Expression in mathematics is combination of variables with the use of operations and given rules. It can be in the form of equation, numbers etc.

We have the expression 25/9.

That means 25 divided in 9 equal parts.

Now the expression 1,

Melanie equally shares 25 meters of paper to create 9 banners.

We have to divide 25 meters of paper into 9 equal banners.

The above expression can be written as a mathematical term,

and that is 25/9.

Now the expression 2,

Quill gives away 9 baseball cards from a pack of 25.

In mathematical terms; 25 - 9.

Now the expression 3,

George invites 25 kids and 9 adults to his birthday party.

That means, the total 25 + 9 = 34 people

In mathematical terms : 25 + 9

Now the expression 4,

Becca creates 9 rows with 25 buttons each.

That means, each row has 25 buttons.

So the total 9 rows have 9 x 25 buttons.

In mathematical terms : 9 x 25

Now the expression 5,

Joe makes 9 equal servings from a 25 ounce bag of peanuts.

That means 25 ounce bag of peanuts equally divided into 9 parts.

The value of n in the equation is n = s / 180 + 2

The subject of a formula is the variable that is being worked out. Subject of the formula is a variable which is expressed in terms of other variables involved in the formula.

Therefore, we have to make n the subject of the formula in the equation.

Hence,

s = (n - 2)180

open the bracket on the right side

s = 180n - 360

add 360 to both sides of the equation

s = 180n - 360

s + 360 = 180n - 360 + 360

s + 360 = 180n

divide both sides by 180

s + 360 = 180n

s  / 180 + 360 / 180 = 180n / 180

The equation for circle is 28g + 16f =260

a) the main equation of circle is ax + by +2gx+ 2fy +c =0     --------- (1)

Now,

putting the points (0,0) , (0,8) and (6,12) one by one, we get,

 For the point (0,0), we get:

                c =o            ----------------------------- (2)

For the point (6,12), we get:

   6x +12y + c = (6)² + (12)²

⇒ 6x +12y +c = 36 +144

⇒ 6x +12y +c = 180          --------------------------- (3)

For the point (0,8), we get,

8y + c = 64                      ----------------------------- (4)

putting c=0,

     8y +0 = 64

⇒ y =64/8

⇒ y = 8

Putting c=0 and y =8, we get,

    6x + 12×8 +0 = 180

⇒ 6x + 96 =180

⇒ 6x = 84

⇒ x = 14

Putting all the values in equation (1), we get:

    (14)² + (8)² +28g +16g + 0 = 0

⇒ 196 + 64 + 28g +16f =0

⇒ 28g + 16f = 260

b) As we know the tangent from the circle:

       y = mx + c

⇒ 8 = -12/6 × 14 +c

⇒ c = 29

Therefore, the equation of the tangent is y = [tex]\frac{6}{12}[/tex]x + 29

Probability of getting 5 notifications in 30 minutes:

The average number of notifications per hour is 12, so the average number of notifications in 30 minutes is 6.

Therefore, the probability of getting 5 notifications in 30 minutes is

P(5 Notifications) = (6 C 5)*(1/2^6)

P(5 Notifications) = 0.0625

The system of equations of Horatio's coins is (c) d = 2n, n + d + q = 57 and 0.05n + 0.10d + 0.25q = 7.25

From the question, we have the following parameters that can be used in our computation:

Number of coins = 57

Worth of coins = $7.25

Type of coins = Nickel, dimes and quarters

Twice as many dimes as nickels

Represent the nickels with n, the dimes with d and the quarters with q

So, we have the following representation

n + d + q = 57

When the nickels, dimes and quarters are converted to dollars, we have the following representations

Nickels = $0.05

Dimes = $0.10

Quarters = $0.25

So, we have the following representation

0.05n + 0.10d + 0.25q = 7.25

Recall that

He has twice as many dimes as nickels

This means that
