Step-by-step explanation:

the given pair (3, 2) is the length of the translation ?

it is really totally simple : you need to add the x value of the translation to the x-cordinate of each point. the same for the y value and the y- coordinates.

A' = (1 + 3, 4 + 2) = (4, 6)

B' = (2 + 3, -2 + 2) = (5, 0)

C' = (-3 + 3, 2 + 2) = (0, 4)

Answer: To find the image of point L(-4,3) after a dilation with a scale factor of 3 and center at the origin, we need to multiply the coordinates of point L by the scale factor.

The formula for dilation is:

(x', y') = (kx, ky)

where (x, y) are the original coordinates, (x', y') are the coordinates of the image, and k is the scale factor.

In this case, k = 3 and the coordinates of point L are (-4, 3).

So,

x' = kx = 3(-4) = -12

y' = ky = 3(3) = 9

Therefore, the image of point L(-4, 3) after the dilation with a scale factor of 3 and center at the origin is (-12, 9).

Answer:  the answer is that you will have $3630 in the account at the beginning of the 7th year.

Step-by-step explanation:

I = Prt

Using this formula:

I = Prt

I = 3000 x 0.035 x 6

I = $630

Therefore, the total amount in the account at the beginning of the 7th year will be

Total = Principal + Interest

Total = $3000 + $630

Total = $3630

Therefore , the solution of the given problem of unitary method comes out to be in June 2022, the total amount due to the finance, exclusive of the insurance, was roughly $47,259.52.

1.1. The statement omits details about the truck's loan term. Therefore, without more details, we are unable to respond to this query.

1.2. Assume that the truck's loan period is n years and that the contractor borrowed P dollars at an annual interest rate of r to buy the water tanker.

M is calculated as (r * P * (1 + r)n) / ((1 + r)n - 1)

5 years + 60 months Equals n

r = 5% / 12 = 0.004166667 (weekly interest rate) (monthly interest rate)

P = $100,000

=> M = (0.004166667 * $100,000 * (1 + 0.004166667)^60) / ((1 + 0.004166667)^60 - 1)

≈> $1,870.24

As a result, the total monthly payments made for the water tanker, including the insurance protection, came to about $1,870.24.

1.3

(Total Amount Borrowed - Amount Paid) / 2

=>  ($100,000 - $1,870.24 * 6) / 2 = $47,259.52 is the sum that is owed.

Therefore, in June 2022, the total amount due to the finance, exclusive of the insurance, was roughly $47,259.52.

Option C is correct. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -3. The solution to system B will be the same as the solution to system A.

What is equations ?

An equation is a mathematical statement that shows the equality of two expressions. It usually contains one or more variables and is solved to find the value of the variable(s) that make the equation true. Equations are used extensively in mathematics, physics, engineering, and many other fields to describe relationships between quantities and to solve problems.

The given system of equations is:

System A:

x + y = 5

3x - 2y = -35

And the solution to this system is (-7, 2).

To obtain System B, we need to manipulate the equations in System A. Let's start by isolating y in the first equation:

y = 5 - x

Now we can substitute this expression for y into the second equation and simplify:

3x - 2(5 - x) = -35

3x - 10 + 2x = -35

5x = -25

x = -5

Now that we have x = -5, we can substitute it back into either of the original equations to solve for y:

x + y = 5

-5 + y = 5

y = 10

So the solution to System B is (-5, 10).

Comparing the two solutions, we see that they are not the same. Therefore, the correct answer is A. To get System B, the second equation in System A was replaced by the sum of that equation and the first equation multiplied by 3. The solution to System B will not be the same as the solution to System A.

Therefore, Option C is correct. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -3. The solution to system B will be the same as the solution to system A.

The probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

A mathematical technique called the Bayes theorem enables us to revise our views or probability regarding an occurrence in light of fresh data or evidence. It has the name of the reverend Thomas Bayes, a statistician and philosopher active in the 18th century. According to the Bayes theorem, the likelihood of an event A given that an event B has already happened is equal to the likelihood of an event B given that an event A has already occurred, multiplied by the prior likelihood of an event A, divided by the previous likelihood of an event B.

The Baye's Theorem is given as:

P(B|A) = P(A|B) × P(B) / P(A)

Here,

P(A) is the probability that a customer ordered a small drink = 0.22.

P(B) is the probability that a customer ordered a hot drink, regardless of whether it was small or medium or large = 0.05.

P(A|B) is the probability that a customer ordered a small drink, given that they ordered a hot drink = 0.2.

Substitute the value we have:

P(B|A) = P(A|B) × P(B) / P(A) = (0.2 × 0.05) / 0.22 ≈ 0.045

Therefore, the probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

The distance the plane traveled from point A with measures an angle of elevation of 16°, to point B with measures an angle of elevation of 28°, is equals to the 11,728.6feet.

Jaya spots an airplane on radar that is currently approaching in a straight line start from point O in above figure, and that will fly directly overhead.

Altitude that plane maintain,h = 7300 feet

Initially, measure an angle of elevation to the plane at point A = 16°

Measure an angle of elevation to the plane at point B = 28°

Now, Let the distance between point A and point B be equal to 'x feet' and distance between point B and point C ( base) be equal to 'y feet'. So, distance between point A to point C = (x + y ) feet. We have to calculate the distance the plane traveled from point A to point B, i.e., x feet. See the above figure carefully, we see in right angled triangle BOC, tan 28° = 7300/y --(1)

In right angled triangle AOC,

tan 16° = 7300/(x + y) --(2)

Cross multiplication in equation (2)

=> tan 16° ( x + y ) = 7300

=> x + y = 7300/tan 16° --(3)

from equation (1), y = 7300/tan 28°

=> y = 7300/0.5317 = 13,729.55

so, x = 7300/tan 16° - y = 7300/0.287 - 13,729.55

= 25,458.12 - 13,729.55

= 11,728.58 ~ 11,728.6

As a result, the Moon orbits the Earth roughly 2.8 billion times while the Sun revolves once around the Milky Way's nucleus.

One cycle of the Sun around the Milky Way's nucleus is thought to take between 225 and 250 million years to complete. The synodic month, or the length of time it takes the Moon to complete one orbit of the Earth, lasts roughly 29.5 days.

We must divide the total time of one orbit of the Sun around the Milky Way by the amount of time it takes for the Moon to orbit the Earth once in order to determine how many times the Moon orbits the Earth during one orbit of the Sun around the Milky Way's centre.

The result is (Total time for one orbit of the Sun around the centre of the Milky Way)/(Time for one orbit of the Moon around the Earth) = (225 million years x 365.25 days per year)/(29.5 days per orbit of the Moon) = around 2.8 billion orbits of the Moon around the Earth.

Answer: The area of each slice of pizza can be calculated by finding the area of the whole pizza and dividing it by the number of slices.

The radius of the pizza is half of the diameter, so the radius is 20/2 = 10 inches.

The area of the whole pizza can be calculated using the formula for the area of a circle:

Area = π × radius^2

Area = π × 10^2

Area = 100π square inches

Since there are 8 slices, each slice has an area of:

100π square inches / 8 = 12.5π square inches

Therefore, the area of the 5 slices that Chris ate is:

5 × 12.5π square inches = 62.5π square inches

This is approximately equal to 196.35 square inches, when rounded to two decimal places.

The rent of the apartment during the 8th year would be approximately $2491.4.

To calculate the rent of the apartment during the 8th year, we need to apply the 11% increase per year for a total of 7 years (from the 2nd to the 8th year). Here's the calculation:

Rent for the 2nd year:

$1200 + (11% of $1200) = $1200 + ($132) = $1332

Rent for the 3rd year:

$1332 + (11% of $1332) = $1332 + ($146.52) = $1478.52

Rent for the 4th year:

$1478.52 + (11% of $1478.52) = $1478.52 + ($162.64) = $1641.16

Rent for the 5th year:

$1641.16 + (11% of $1641.16) = $1641.16 + ($180.53) = $1821.69

Rent for the 6th year:

$1821.69 + (11% of $1821.69) = $1821.69 + ($200.39) = $2022.08

Rent for the 7th year:

$2022.08 + (11% of $2022.08) = $2022.08 + ($222.43) = $2244.51

Rent for the 8th year:

$2244.51 + (11% of $2244.51) = $2244.51 + ($246.90) = $2491.41

Therefore, the rent of the apartment during the 8th year would be approximately $2491.4.

The relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y, is a linear equation y = (3/5)x.

What is a linear equation?

A linear equation is an algebraic equation in which each term is either a constant or a product of a constant and a variable raised to the first power (i.e., the variable is not squared or cubed). The general form of a linear equation with one variable, x, is:

ax + b = 0

Now,

We are given that there is a proportional relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y. Let k = constant of proportionality.

Then, we can write the equation as:

y = kx

We also know that Trevor turns the crank 5 times to lift a box 3 feet.

Now

3 = k(5)

Solving for k, we get:

k = 3/5

Substituting this value of k in the equation, we get:

y = (3/5)x

Lorie should deposit $6,986.05 today at 5.25% to have enough money to pay off the loan in 7 months.

To determine the amount that Lorie should deposit today to have enough money to pay off the loan.

We use the simple interest formula for accrued amount.

A = P( 1 + rt )

Where A is total amount, P is initial amount, r is interest rate and t is elapsed time.

Given that;

First, converting R percent to r a decimal

r = R/100

r = 5.25/100

r = 0.0525

Next, we put time into years for simplicity,

t = 7 months / 12 months

t = 7/12 year

Plug the values into the above formula.

A = P( 1 + rt )

P = A / ( 1 + rt )

P = $7,200 / ( 1 + ( 0.0525 × 7/12 ) )

P = $7,200 / ( 1 + 0.030625 )

P = $7,200 /  1.030625

P = $6,986.05

If sequence 23,19,15, the nth term of the sequence 23, 19, 15 is given by the formula aₙ = 23 - 4(n-1).

To find the explicit formula for the nth term of the sequence 23, 19, 15, we need to look for a pattern in the sequence. We can observe that each term in the sequence is obtained by subtracting 4 from the previous term. Therefore, we can write the recursive formula for this sequence as:

a₁ = 23

aₙ = aₙ-1 - 4, for n ≥ 2

To find the explicit formula, we need to use the recursive formula to eliminate the dependence on the previous term. We can do this by repeatedly substituting the recursive formula into itself, until we get an expression for an in terms of a1:

a₂ = a1 - 4 = 23 - 4 = 19

a₃ = a₂ - 4 = (a₁ - 4) - 4 = a1 - 8 = 23 - 8 = 15

a₄ = a₃ - 4 = (a₁ - 8) - 4 = a1 - 12 = 23 - 12 = 11

From this pattern, we can see that each term can be written as:

aₙ = a₁ - 4(n-1)

Substituting a1 = 23, we get the explicit formula:

aₙ = 23 - 4(n-1)
