Which of these sequences of transformations would not return a shape to its original position?

Group of answer choices

1. Translate 3 units up, then 3 units down.

2. Reflect over line p, then reflect over line p again.

3. Translate 1 unit to the right, then 4 units to the left, then 3 units to the right.

4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.

Answers

Answer:

4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.

Step-by-step explanation:

Option 1, 2 and 3 will return a shape back to its original because:

1. 3 units up and 3 units down are direct opposite and will cancel out one another. Hence, the shape will return to its initial position.

2. Reflect over line p, and over p again.

This actions are also direct opposite and also have the same effect as (1)

3. Translate 1 unit to the right and 3 units to the right.

This equates to 4 units to the right and it will cancel out the translation of 4 units to the left.

4. Rotate 120 counter clockwise and another 220 counterclockwise will not make a shape go back to its original position.

a rectangular television's length is 3 inches more than twice its width. The perimeter of the television is 144 inches. What is the width of the television?
A. 23
B. 24
C. 25
D. 26
can someone explain bc I got small brain ykyk

Answers

Answer: A. 23

23 - Width

23x2 = 46

46+3 = 49

So..

49 - Length

lx2+wx2 = perimeter

49x2 = 98

23x2 = 46

98+46 = 144

The width of the television will be 23 inches. Then the correct option is A.

What is the perimeter of the rectangle?

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The length of a rectangular television is 3 inches longer than its width. The display has a 144-inch perimeter. Then the equation is given below.

L = 2W + 3 ...1

144 = 2(L + W) ...2

From equations 1 and 2, then have

144 = 2(2W + 3 + W)

72 = 3W + 3

3W = 69

W = 23 inches

The width of the television will be 23 inches. Then the correct option is A.

More about the perimeter of the rectangle link is given below.

4 more than one third of a number n is 6. An equation is? The solution is n =?

Answers

Answer:

[tex]\frac{1}{3}[/tex]n + 4 = 6

Step-by-step explanation:

Given problem:

4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number = ?

Solution:

let the number = n

So, 4 more than one third of a number;

One third of n = [tex]\frac{1}{3}[/tex]n

4 more;

[tex]\frac{1}{3}[/tex]n + 4

is 6;

[tex]\frac{1}{3}[/tex]n + 4 = 6 (equation of the expression)

Let us now solve the equation:

[tex]\frac{1}{3}[/tex]n + 4 = 6

[tex]\frac{1}{3}[/tex]n = 6 - 4

[tex]\frac{1}{3}[/tex]n = 2

n = 6

The density of gold is 19.3 grams per cubic centimeter. Rachel determines that the density of a coin is 18.7 grams per cubic centimeter. Based on this evidence, she concludes that the coin is not gold or at least not entirely gold. Is this an example of inductive or deductive reasoning?

Answers

Answer:

The reasoning is a deductive.

The reason is because the pattern of thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the gold ) are used to support the conclusion.

Step-by-step explanation:

Gnerally the reasoning is a deductive.

The reason is because the pattern of thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the conclusion.

what is an expression equivalent to m^238/m^-79 in the form m^v, where v is an integer?

Answers

Answer:

[tex]m^{317}[/tex]

Step-by-step explanation:

In indices, the division postulate is true:

[tex]\frac{a^m}{a^n} = a^{m-n}[/tex]

Apply this to the question:

[tex]\frac{m^{238}}{m^{-79}} \\= m^{238-(-79)}\\= m ^{238+79}\\= m^{317}[/tex]

Hence the expression expressed in the form [tex]m^v \ is \ m^{317}[/tex]

{(5²)} ³×5⁴}÷5⁷ simplify and express the following as exponent

Answers

Answer:

The answer is 5³.

Step-by-step explanation:

You have to apply Indices Law :

[tex] {a}^{m} \times {a}^{n} ⇒ {a}^{m + n} [/tex]

[tex] {a}^{m} \div {a}^{n}⇒ {a}^{m - n} [/tex]

[tex] { ({a}^{m} )}^{n} = {a}^{mn} [/tex]

So for this question :

[tex]( {( {5}^{2}) }^{3} \times {5}^{4} ) \div {5}^{7} [/tex]

[tex] = ( {5}^{6} \times {5}^{4} ) \div {5}^{7} [/tex]

[tex] = {5}^{10} \div {5}^{7} [/tex]

[tex] = {5}^{3} [/tex]
