Answer:

a) Center of dilation (0,0)

b) Scale factor = 2

Step-by-step explanation:

Dilation of Polygons

The triangle ABC has its vertices at A(-2,2), B(4,2), and C(-2,-2).

The triangle A'B'C' has its vertices at A'(-4,4), B'(8,4), and C'(-4,-4).

Since A'B'C' is a dilation of ABC, we check if all its vertices are proportional with the same scaling factor.

Both vertices of A' are twice the vertices of A: (-4,4)=2*(-2,2)

Both vertices of B' are twice the vertices of B: (8,4)=2*(4,2)

Both vertices of C' are twice the vertices of C: (-4,.4)=2*(-2,-2)

The proportionality of the coordinates of the vertices tells us the center of dilation must be the origin of coordinates (0,0).

The scale factor is the constant number all the vertices are multiplied by, that is, scale factor = 2

An investment of $1500 is earning 7% simple interest each year. How much will the investment be worth after one year?

Answers

Answer:

$1,605

Step-by-step explanation:

As, 7% of $1,500 is = $105

So, the investment is = Principcal + Interest.

= $1,500 + $105 = $1,605

The value of investment after one year will be $1,605.

About Investment:

It is an asset invested to increase wealth and save money from the hard earned income. Investment is primarily to obtain an extra source of income or gain profit from the investment over a specific period of time.

Computation of investment after one year:

Given that,

Principal[P] = $1,500.

Rate[R] = 7%.

Time[T] = 1 year.

Formula of simple interest[S.I] :

[tex]\text{ S.I.} = \dfrac{P\times R\times\ T}{100} .\\\\ \text{S.I.} = \dfrac{\$1,500\times7}{100}\\\\ \text{S.I. }=\$105.[/tex]

Investment after one year will be :

[tex]\text {Investment}= \text{Principal} +\text{Interest}.\\\text{Investment}=\$1,500+\$105\\\text{Investment} =\$1,605[/tex]

Hence, the worth of investment after one year will be $ 1,605.

I hope this is the way it must be calculated

standard form. Ax+By=C. what is c, how do i find the slope, how do i find the x intercept, how do i find the y intercept. can you please give a simple example?

Answers

c represents the y-intercept (the “b” in slope intercept form) to find the slope, you simply change it to slope intercept form ( move the Ax to the other side of the equation and divide by B *whatever number is attached to the y that you need to get rid of to get y alone*) to find the x intercept, you replace y with a zero (this is because you don’t want to find y so you are taking it away from the equation so you are left with Ax=c) and you divide A by c to get x alone (bc a is attached to the x so you divide to get rid of it) and the same process for y-intercept. except you are placing the zero in the x rather than the y.

sample example:
2x+6y=12
finding the slope:
6y=-2x+12
(divide by 6)
y=-2/6+2
slope= -2/6

y intercept:
2x+6y=12
2(0)+6y=12
6y=12
(divide by 6)
y=2

x-intercept

2x+6y=12
2x+6(0)=12
2x=12
(divide by 2)
x=6

They have different totals because the 10 dollars your putting in every 2 weeks. Now with the 20 dollars you doing it every month so they have different totals because ones getting put in every month and the other is getting put in every 2 weeks.

i need answer today . Jill made the model below to show the quotient

.

An image shows three groups of three tenths and two hundredths.

Which of the following explains the mistake Jill made?

A.

Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.

B.

Jill used groups of 3 tenths and 2 hundredths rather than groups of 4 tenths.

C.

Jill used 3 groups of 3 tenths and 2 hundredths rather than 2 groups.

D.

Jill used groups of 3 tenths and 2 hundredths rather than groups of 3 tenths and 8 hundredths.

Answers

Answer:

Step-by-step explanation: By looking at the image it shows 2 not 4.

The only option that explains the mistake Jill made in the model is;

Option A; Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.

The model Jill made is to show the quotient of 1.28 ÷ 4.

Now, this means she wants to divide 1.28 into 4 equal parts. Thus, the model must show 4 identical quotients.

The image of the model we are seeing from Jill is showing;

3 groups of 3 tenths and 2 hundredths.

Since it is showing 3 groups instead of 4 groups, the it is clear that Jill made a mistake in her model.

In conclusion, the only option that identifies the mistake correctly is option A.

Step-by-step explanation:

The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS

Therefore;

in Segment MN, segment QM = segment QN, by definition of bisected line

Segment OQ = Segment OQ by reflexive property

∠OQM = ∠OQN = 90° by definition of perpendicular bisector

∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency

The corner market sells potatoes at a rate of 1/2 dollars per potato.
1. Amanda is only able to spend $5 on potatoes. What is the most number of potatoes she can buy?
2. Sam wants to buy 15 potatoes. How much will that cost him?

Answers

Answer:

The cost of 15 potatoes is $7.50

Step-by-step explanation:

The potatoes are sold at a rate of $0.5 per potato.

1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.

Amanda can buy at most 10 potatoes

2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:

15 * $0.5 = $7.50

The cost of 15 potatoes is $7.50
