Triangles A B C and A double-prime B double-prime C double-prime are shown. Triangle A double-prime B double-prime C double-prime is smaller and to the right of triangle A B C. Which transformations could have taken place to map △ABC to △A"B"C"? a reflection and a dilation a rotation and a dilation a translation and a dilation a reflection and a translation

PLEASE I NEED HELP ASAP

Answers

A smaller shape would be a dilation.

A move to the right would be a transition. (As long as the letters for the triangle are in the same orientation).

The answer should be:

A dilation a translation

There are various types of transformations that can be applied to a coordinate point. The new point could become compressed/enlarged, reflected, rotated, etc.

The transformations that transform [tex]\triangle ABC[/tex] to [tex]\triangle A"B"C"[/tex] are a translation and a dilation.

Given that:

[tex]\triangle A"B"C"[/tex] is smaller than [tex]\triangle ABC[/tex]

This means that sides of [tex]\triangle ABC[/tex] were dilated (i.e. compressed) to give the sides of [tex]\triangle A"B"C"[/tex]

Also:

[tex]\triangle A"B"C"[/tex] is at the right of [tex]\triangle ABC[/tex]

This means that [tex]\triangle ABC[/tex] was translated (i.e. shifted) to give [tex]\triangle A"B"C"[/tex]

Hence, the correct option is: a translation and a dilation.

The amount of rainfall each month over the past four years is shown below

Answers

Answer: C

Step-by-step explanation: On Edge 2020

D) The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

What is Symmetrical Graph?

A graph is said to be symmetric about a line if the graph remains unchanged when we reflect the graph on one side of the line to the other side.

Given is a histogram representing the amount of rainfall in the last 4 years or 48 months.

So the graph is symmetrical if we draw a line at the point 3.

Amount of rainfall is 0 - 1 inches for first 11 months. Then it is 1.01 - 2 inches for the next 8 months. Then 2.01 - 3 for the next 5 months and again 3.01 - 4 for the next 5 months. Then it is 4.01 - 5 and 5.01 - 6 for the next 8 years and 11 years respectively.

19 months has the rainfall less than 2.01 inches.

19 months has the rainfall greater than 4 inches.

Only 48 - (19 + 19) = 10 months are having rainfall in between 2.01 and 4.

So majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Hence the correct option is D.

Why would a person choose a PPO over an HMO?

Answers

Answer:

With an HMO plan, you pick one primary care physician. All your health care services go through that doctor. That means that you need a referral before you can see any other health care professional, except in an emergency. Visits to health care professionals outside of your network typically aren’t covered by your insurance.

PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.

Staying inside your network means smaller copays and full coverage. If you choose to go outside your network, you'll have higher out-of-pocket costs, and not all services may be covered.

This got me 100% on the assignment!

PPO plans give you flexibility. You don’t need a primary care physician. You can go to any health care professional you want without a referral inside or outside of your network.

Staying inside your network means smaller copays and full coverage.

HMO providers are paid on a per-member basis, regardless of the number of times they see a member.

This makes HMO plans a more economical choice than PPOs. An HMO generally only covers care received from the plan's contracted providers, known as “in-network” providers.

PPO plans generally are more expensive than HMO plans. However, due to the pooling of people in a PPO network, fees associated with health care will be lower for participants.

In other words, you will pay far less for services if you are in a PPO plan vs. not having insurance at all.

So, the person choose a PPO over a HMO.

Question
George invested $4400 in an account with annually compounded interest. After 5 years, he had $5790 in the account. What
was the interest rate of the account? Round your answer to one decimal place. Do not write the percent sign,​

Answers

compounded annually:

A = P(1 + r)^t

A = accumulated amount = $5790
P = original amount invested = $4400
r = interest rate (in decimal form) = ? what it is asking for
t = time in years = 5 years

$5,790 = $4,400(1 + r)^5
r = 5.644% or 0.05644

Answer:

The rate of interest was approx 5.64%.

Step-by-step explanation:

The compound interest formula is :

[tex]A=p(1+\frac{r}{n} )^{nt}[/tex]

Here p = 4400

r = ?

n = 1

t = 5

A = 5790

Now putting the values in formula we get;

[tex]5790=4400(1+\frac{r}{1} )^{5}[/tex]

=> [tex]5790=4400(1+r )^{5}[/tex]

=> [tex]\frac{5790}{4400} =(1+r )^{5}[/tex]

=> [tex]1.316=(1+r )^{5}[/tex]

=> [tex]1+r=\sqrt[5]{1.316}[/tex]

r = 0.0564

In percentage it is [tex]0.0564\times100[/tex] = 5.64%

Hence, the rate of interest was approx 5.64%.

The length of a rectangle is 2 m greater than the width. The area is 168 m2 Find the length and the width

Answers

Answer:

Length = 14m

Width = 12m

Step-by-step explanation:

The length of a rectangle is 2m greater than the width.

The area of the rectangle = 168m²

Let's say the width is x meters.

The length will be (x + 2) meters.

Area of a rectangle = length × width

x(x + 2) = 168

x² + 2x - 168 = 0

Solving x by applying the quadratic formula we get;

x = 12 or -14

Since the width cannot be negative, we take 12 meters to be the dimensions of the width.

The length = 12 + 2 = 14 meters.

Final answer:

To find the length and width of the rectangle, we formulate an equation based on the known relationship between the dimensions and the given area. Solving the equation, we get the width as 12 m and length as 14 m.

Explanation:

The question is about finding the length and width of a rectangle given the area and a relationship between the two dimensions. We can set up an equation based on the information given and the formula for the area of a rectangle. Namely, the area of a rectangle is equal to its length multiplied by its width (A = lw).

According to the problem, the length of the rectangle is 2 m more than the width. We can express this relationship as L = W + 2. We also know that the area of the rectangle is 168 m2, which results in the equation (W + 2)W = 168.

Solving this quadratic equation, we find that the width (W) is 12 m and the length (L) is 14 m. These are the dimensions of the rectangle.

When an oil tank is 7/12 full, it contains 5 1/4gallons. How many gallons does it hold when full?

Answers

Final answer:

To determine the full capacity of the tank, the amount of oil it contains when it is 7/12 full (5 1/4 gallons) is divided by 7/12. After conversion and calculation, the full capacity is found to be 9 gallons.

Explanation:

The student's question asks, "When an oil tank is 7/12 full, it contains 5 1/4 gallons. How many gallons does it hold when full?" To find the full capacity of the tank, we divide the amount of oil when the tank is partially full by the fraction representing how full it is.

First, convert 5 1/4 gallons to an improper fraction: 5 1/4 = 21/4 gallons. Then divide this amount by 7/12 to find the full capacity.

Full capacity = (21/4) ÷ (7/12) = (21/4) × (12/7) = (21×12) / (4×7) = 252 / 28 = 9 gallons.

So, the full capacity of the oil tank is 9 gallons.

Answer:

17 = 17^1

Step-by-step explanation:

Factor the following integer:

17

17 is not divisible by 2 since 17 is odd and 2 is even:

17 = 17 (17 is not divisible by 2)

The sum of the digits of 17 is 1 + 7 = 8, which is not divisible by 3. This means 17 is not divisible by 3:

17 = 17 (17 is not divisible by 2 or 3)

The last digit of 17 is not 5 or 0, which means 17 is not divisible by 5:

17 = 17 (17 is not divisible by 2, 3 or 5)

Divide 7 into 17:

| | 2 | (quotient)

7 | 1 | 7 |  

- | 1 | 4 |  

| | 3 | (remainder)

17 is not divisible by 7:

17 = 17 (17 is not divisible by 2, 3, 5 or 7)

The alternating sum of the digits of 17 is 1 - 7 = -6, which is not divisible by 11. This means 17 is not divisible by 11:

17 = 17 (17 is not divisible by 2, 3, 5, 7 or 11)

Divide 13 into 17:

| | | 1 | (quotient)

1 | 3 | 1 | 7 |  

| - | 1 | 3 |  

| | | 4 | (remainder)

17 is not divisible by 13:

17 = 17 (17 is not divisible by 2, 3, 5, 7, 11 or 13)

No primes less than 17 divide into it. Therefore 17 is prime:

17 = 17

Since 17 is prime it has an exponent of 1:
