Prompt: We recently completed a unit in math about transformations.

Compare and contrast the three types of transformations: translations, reflections, and rotations.

Include the algebraic rules, whether each transformation preserves congruence and any examples of

real-world application.

Answers

Answer 1

The translations, reflections, and rotations are types of transformations that change an original object to form a new image, each with its own specific rule and properties. They are used in a variety of real-world applications to change the position or orientation of objects.

There are 3 types of Transformations :

(i) Translation: A translation involves moving an object from one place to another without changing its size or orientation.  

The algebraic rule for a translation is to add the same constant to each coordinate of each point

The Translations preserve congruence, meaning that corresponding parts of congruent figures will still be congruent after a translation.

An example of a real-world application of translation is moving a store to a new location.

(ii) Reflection: A reflection involves flipping an object over a line or point, creating a mirror image.

The algebraic rule for a reflection is to negate the value of one of the coordinates.

Reflections preserve orientation, meaning that the orientation of the reflected image is opposite that of the original object.

An example of a real-world application of reflection is looking at your reflection in a mirror.

(iii) Rotation: A rotation involves turning an object about a fixed point, called the center of rotation, through a certain angle.

The algebraic rule for a rotation is to multiply each coordinate by a rotation matrix.

Rotations preserve distance and angle measures, meaning that the lengths of corresponding parts and the angles between them are equal in the original and rotated images.

An example of a real-world application of rotation is turning a steering wheel to change the direction of a car.

Step-by-step explanation:

Interest of 3% a year of principal of 200,000 = 6000

monthly payment of 843 also includes a portion of amortization of the principal itself, which you can ignore cause the question only asked for the interest portion.

this is an unclear question cause it didn't say PER YEAR interest paid.  you only need to remember interest% * principal = ANNUAL interest payment $.  Then you can divide that over 12 months, which is 500$ per month.

parallelogram has sides of lengths 35 inches and 75 inches. One angle has measure of140°. Find the length of each diagonal.

Answers

The length of diagonal of a parallelogram is 2546 inches.

What is a parallelogram?

A quadrilateral with equal pairs of opposing sides and angles is referred to as a parallelogram. It has a pair of opposing sides that are parallel to one another. The inner angles are supplementary in nature, meaning that the sum of them equals 180 degrees. A parallelogram's diagonals are bisected by one another, or divided into two equal portions. A parallelogram's internal angles add up to 360 degrees.

The diagonals of parallelogram are given by:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

Given the two sides are 35 and 75 inches.

We also know that the adjacent angles of parallelogram are supplementary:

∠A + ∠B = 180

140 + ∠B = 180

∠B = 40

Substitute the value of sides and angle in the equation:

x = √(a^2 + b^2 – 2ab cos A) = √(a^2 + b^2 + 2ab cos B)

x = √((35)^2 + (72)^2 + 2(35)(72) cos 140)

x = 1225 + 5184 + (5040)(-0.766)

x = 1225 + 5184 - 3860

x = 2546 inches

Hence, the length of diagonal is 2546 inches.

King Neptune, a 34-foot tall statue that

3 13

5 -foot shadow. If Jane is 5’9" tall and is

standing nearby, find the length of her


shadow

Answers

The length of Jane's shadow is approximately 2.85 feet

To find the length of Jane's shadow, we can use the principle of similar triangles.

The ratio of the shadow length to the object height is the same for both King Neptune and Jane, then we can set up a proportion:

(shadow length of King Neptune) / (height of King Neptune) = (shadow length of Jane) / (height of Jane)

Given that King Neptune's shadow is 3 13 5 feet and the statue is 34 feet tall.

By substituting these values into the proportion:

(3 13 5 feet) / (34 feet) = (shadow length of Jane) / (5' 9")

To find the shadow length of Jane, we can cross-multiply and solve for the shadow length:

(3 13 5 feet) * (5' 9") = (shadow length of Jane) * (34 feet)

Converting Jane's height into feet: 5'9" = 5*12 +9 = 69 inches = 5.75 ft

(3 13 5 feet) * (5.75 ft) = (shadow length of Jane) * (34 feet)

shadow length of Jane = (313.5*5.75) / 34 = 2.85 ft

So, The length of Jane's shadow is approximately 2.85 feet.

If Lilyana runs a cake decorating business for which 10% of her orders come over telephone , then probability that it takes fewer than 5 orders for Lilyana to get her first telephone is 0.3439  .

The geometric distribution is used to calculate the required probability ,

In this case, the success is a telephone order, and

the failure is an order placed in some other way.

Let probability of success is ⇒ p , and

let the number of orders needed to get the first telephone order be = x . Then, X follows a geometric distribution with parameter p, so we have:

Probability of P(X = k) is = (1-p)^(k-1) × p ;

where k is the number of orders needed.

the probability of success (p) is  = 10% = 0.1

we have to find the probability that it takes fewer than 5 orders for Lilyana to get her first telephone order of the month.

that means : P(X<5) = P(X=1) + P(X=2) + P(X=3) + P(X=4)

Substituting the values of p = 0.1 ,

we get ;

= (1-0.1)⁰ × 0.1 + (1-0.1)¹ × 0.1 + (1-0.1)² × 0.1 + (1-0.1)³ × 0.1

Simplifying further ,

we get ;

= 0.1 + 0.09 + 0.081 + 0.0729

Adding all the terms ,

we have ;

= 0.3439

Therefore , the probability that it takes fewer than 5 orders for Lilyana to get her first telephone order of the month is 0.3439.

Answers

To find the balance of the account after 3 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where A is the final amount, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the initial principal is $2,600, the interest rate is 4.2% (expressed as a decimal), the number of times the interest is compounded per year is 12 (monthly), and the number of years is 3.

So, we can plug these values into the formula:

A = 2600(1 + 0.042/12)^(12*3)

A = 2600(1.0035)^36

A = 2600 * 3.876

4 painters that have completed 12 rooms in 8 hours. assuming they are working at the same efficiency, how many hours does it take 7 painters to paint 21 rooms?

Answers

Answer:  We can use the concept of rates to solve this problem.

A rate is a ratio of the amount of work done to the amount of time it takes to do the work. We can find the rate of work for the 4 painters by dividing the number of rooms they painted by the number of hours it took them:

Rate = Rooms painted / Hours

Rate = 12 rooms / 8 hours = 1.5 rooms per hour

Now we can use this rate to find out how long it will take 7 painters to paint 21 rooms. To do this, we'll use the formula:

Time = Rooms / Rate

Time = 21 rooms / 1.5 rooms per hour = 14 hours

So it would take 7 painters working at the same efficiency as the 4 painters 14 hours to paint 21 rooms.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side

Given that equation is,

c = 3.5b

Here b is the number of loaves of bread and c is the total cost of the bread.

All the table values matches the equation when we substitute the value of b and c in the equation.

But number of loaves of bread cannot be fractions or negative numbers.

So the most viable solution is the third table consisting of values of b as  0, 3, 6, 9 and corresponding value of c as 0, 10.5, 21, 31.5.

⇒ -7 = a(1)² +b (1) +6

⇒ a + b + c=-7 -----------1

At n=2, T₂ = 0

⇒ 0 = a(2)²+b(2)+c

4a+2b+c=0 ---------------2

At n=3, T = 9

⇒ 9 = a(3)²+b(3) +c

⇒ 9a+3b+c= 9 ---------3

Subtracting 3 from 2

⇒-5a-b = -9 --------4

Subtracting 2 from 1

-3a-b = -7  -----------5

Subtracting 5 from 4

2a = 2

⇒ a=1

Using eq 5, we get

-3(1) - b = -7

-b = -7 + 3

b = 4

From eq 1, a + b + c=-7 we get the value of c,

1 + 4 + c = -7

c = -7 -5

c = -12

substitute the values of a, b, and c in Tn = an²+bn + c

Tn = n² + 4n - 12

Hence the general term of the given quadratic number pattern is given by Tn = n²+4n-12.

For the shape below, if side BD = 29 and side AC = 3x - 4, find x.

Answers

x=11
since sides BD and AC are congruent, then the equation would be 29=3x-4

Answer:

x = 11

Step-by-step explanation:

We know that the answer we will get will be the same as BD because BD and AC are congrudent, meaning that they are exactly equal shape and size. To find 'x' our equation would be: 29 = 3x - 4. To figure this out we just add 29 and 4 which gives us 33 and then divide that by 3 which gives us 11 (our answer)

Answer:

b

Step-by-step explanation:

the sum of the 3 angles in the triangle = 180°

sum the 3 angles and equate to 180

2x + 1 + 5x + 5 + 90 = 180

7x + 96 = 180 ( subtract 96 from both sides )

7x = 84 ( divide both sides by 7 )

x = 12
