What is the image of (-8,- 7) after a dilation by a scale factor of 2 centered
at the origin?

Answers

Answer 1

Answer:   (-16, -14)

==========================================================

Explanation:

To get that result, you multiply each coordinate by the scale factor 2

We have

-8*2 = -16-7*2 = -14

So that's why (-8,-7) moves to (-16, -14)

This trick only works if the origin is the center of dilation.

7400 dollars is placed in an account with an annual interest
rate of 6%. To the nearest year, how long will it take for the
account value to reach 19200 dollars?

Answers

Answer:

17

Step-by-step explanation:

We have the following equation for compounding annual interest

AV=PV(1+i)ⁿ

We have

19200=7400(1+.06)ⁿ

Solve for n

divide both sides by 7400

2.594=(1.06)ⁿ

then use the following rule for exponents

[tex]x^y=z\\log_xz=y[/tex]

which means that

[tex]log_{1.06}2.594=n[/tex]

Solve and get

Answers

Answer:

Step-by-step explanation:

2y - 6 + y = 180   {Co-interior angles}

3y - 6   = 180

      3y = 180 + 6

     3y = 186

       y = 186/3

       y = 62

y + w = 180     {Linear pair}

62 +w = 180

       w = 180 - 62

        w = 118

ΔILK ,

∠L +  ∠ I + ∠K = 180  {Angle sum property of triangle}

w + z + 30 = 180

118 + z + 30 = 180

     z +  148  = 180

               z =180-  148

                z = 32

x = z    {Alternate interior angles}

x = 32

If a1=10 and an=an-1+4 then find the value of a5

Answers

Answer:

26

Step-by-step explanation:

Each term is the previous with 4 added to it.

a1 = 10, a2 = 14, a3 = 18, a4 = 22, a5 = 26

The value of [tex]a_{5}[/tex] will be equal to 26 .

It is given that [tex]a_{1}[/tex]= 10 and [tex]a_{n} = a_{n-1} + 4[/tex].

We have to find the value of [tex]a_{5}[/tex].

What do you mean by sequences ?

Sequences are a list of numbers which are arranged in a special manner i.e., 2 , 4 , 6 , 8 numbers of this sequence gets increased by 2 every time.

As per the question ;

The first term ;  [tex]a_{1}[/tex]= 10

and given ;

[tex]a_{n} = a_{n-1} + 4[/tex]

So ;

2nd term will be ;

[tex]a_{2} = a_{1} + 4[/tex]

[tex]a_{2}[/tex] = 10 + 4

or

[tex]a_{2}[/tex] = 14

Now ;

3rd term will be ;

[tex]a_{3} = a_{2} + 4[/tex]

[tex]a_{3} = 14 + 4[/tex]

[tex]a_{3}[/tex] = 18  

Hence , the common difference is d = 4.

So ;

4th term will be ;

[tex]a_{4}[/tex] = 18 + 4

[tex]a_{4}[/tex] = 22

and

5th term will be ;

[tex]a_{5}[/tex] = 22 + 4

[tex]a_{5}[/tex] = 26

Thus , the value of [tex]a_{5}[/tex] will be equal to 26 .

help me solve for t please

Answers

Answer:

t = 1/3

Step-by-step explanation:

for this problem we have two different shapes, what we need to do is find out the proportional relationship between the two to solve for t, lets take one of the measurements from the smaller shape, we will go with... JK at 5

now all we need to do is divide that by the larger shapes same side, in this case that would be RP at 22.5, heres what that looks like so far

5 / 22.5 = 0.2-> (the two goes on forever, normally this is represented by a line above the infinite number, this is what they call a Repeating Decimal)

ok, so now that we have the rate of change between the two shapes figured out, now we just make the same change to the last side from the same side on the first shape, wich is LK to QR as shown

1.5 * 0.2-> = 0.3->

and if 0.3 is = to 1/3, so t = 1/3

i hope this helped you out, im sorry if im a little late lol, make note that all of this can be applied to similar situations, just figure out the change(s) that happened from one shape to the other, and make that same change on the unknown side or area

Answer:

Follow the lines

Step-by-step explanation:

Follow what the lines go with what the table has.

To make this really easy, find the slope of the line

To do this you find an easy point.

Ex. x=3 and y= 150

then take it into a slope y-intersept formula

y= mx

150= 3x

50 = x

so for every time x goes up one interval, y increases at a rate of 50.

And for y, do the opposite, for every 50 y, x goes up 1.

By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)

y= 50x is ur slope/formula

Answers

Answer:

y = -5x - 5

Step-by-step explanation:

Given the standard form of an equation as y=mx+c

m is the slope

c is the intercept

Using the coordinate points

(1, 0) and (0,-5)

m = -5-0/0+1

m = -5/1

m = -5

Get the intercept

Intercept is the point where thee line cuts the y axis. intercept is -5

Get the equation:

Recall that y = mx+c

y = -5x + -5

y = -5x - 5

This gives the required equation

how to solve improper fraction of 4/5 - 1/4???

Answers

they aren’t improper tho?
4/5 - 1/4
find a common denominator
it would be 20
4/20 - 1/20
change the numerator too
16/20 - 5/20
it would give you 11/20

Answer:

11/20

Step-by-step explanation:

First, you have to find a common denominator between the two fractions, 4 and 5 can both equal 20 so we change the denominators to 20, 4/5 =16/20 since whatever we multiply on the bottom we multiply on the top, now for 1/4 we change it to 5/20. Now for the question, we subtract since that's what it's asking, so 16/20 - 5/20, 16 - 5 equals 11 and the denominators stay the same so the answer would be 11/20

What is the difference between a concentration camp and an extermination camp?help Please help from A Bachelors Complaint of the Behaviour of Married Peopleby Charles LambAs a single man, I have spent a good deal of my time in noting down the infirmities of Married People, to console myself for those superior pleasures, which they tell me I have lost by remaining as I am.I cannot say that the quarrels of men and their wives ever made any great impression upon me, or had much tendency to strengthen me in those anti-social resolutions, which I took up long ago upon more substantial considerations. What oftenest offends me at the houses of married persons where I visit, is an error of quite a different description;it is that they are too loving.Not too loving neither: that does not explain my meaning. Besides, why should that offend me? The very act of separating themselves from the rest of the world, to have the fuller enjoyment of each others society, implies that they prefer one another to all the world.But what I complain of is, that they carry this preference so undisguisedly, they perk it up in the faces of us single people so shamelessly, you cannot be in their company a moment without being made to feel, by some indirect hint or open avowal, that you are not the object of this preference. Now there are some things which give no offence, while implied or taken for granted merely; but expressed, there is much offence in them. If a man were to accost the first homely-featured or plain-dressed young woman of his acquaintance, and tell her bluntly, that she was not handsome or rich enough for him, and he could not marry her, he would deserve to be kicked for his ill manners; yet no less is implied in the fact, that having access and opportunity of putting the question to her, he has never yet thought fit to do it. The young woman understands this as clearly as if it were put into words; but no reasonable young woman would think of making this the ground of a quarrel. Just as little right have a married couple to tell me by speeches, and looks that are scarce less plain than speeches, that I am not the happy man,the ladys choice. It is enough that I know I am not: I do not want this perpetual reminding.The display of superior knowledge or riches may be made sufficiently mortifying; but these admit of a palliative. The knowledge which is brought out to insult me, may accidentally improve me; and in the rich mans houses and pictures,his parks and gardens, I have a temporary usufruct at least. But the display of married happiness has none of these palliatives: it is throughout pure, unrecompensed, unqualified insult.Marriage by its best title is a monopoly, and not of the least invidious sort. It is the cunning of most possessors of any exclusive privilege to keep their advantage as much out of sight as possible, that their less favoured neighbours, seeing little of the benefit, may the less be disposed to question the right. But these married monopolists thrust the most obnoxious part of their patent into ourfaces.Nothing is to me more distasteful than that entire complacency and satisfaction which beam in the countenances of a new-married couple, in that of the lady particularly: it tells you, that her lot is disposed of in this world: that you can have no hopes of her. It is true, I have none; nor wishes either, perhaps: but this is one of those truths which ought, as I said before, to be taken for granted, not expressed. The excessive airs which those people give themselves, founded on the ignorance of us unmarried people, would be more offensive if they were less irrational. We will allow them to understand the mysteries belonging to their own craft better than we who have not had the happiness to be made free of the company: but their arrogance is not content within these limits. If a single person presume to offer his opinion in their presence, though upon the most indifferent subject, he is immediately silenced as an incompetent person. Nay, a young married lady of my acquaintance, who, the best of the jest was, had not changed her condition above a fortnight before, in a question on which I had the misfortune to differ from her, respecting the properest mode of breeding oysters for the London market, had the assurance to ask with a sneer, how such an old Bachelor as I could pretend to know any thing about such matters.All the following are mocked in the passage EXCEPTA.intelligence gained as a result of marriageB.undisguised preference of married couples for their spouseC.condescension of married females to bachelorsD.married individuals presumptive knowledgeE.overt cruelty of married couples to unattractive unmarried femalesPlease select the best answer from the choices providedABCDE PLEASE ANSWER HURRY!!
