Figure 1 Is Similar To Figure 2. What Is The Height Of Figure 1?8 Units1 Unit2 Units4 Units

Answers

Answer 1

The height of figure 1 that is similar to figure 2 is: D. 4 units.

What are Similar Figures?

The corresponding linear measurements of similar figures are proportional. Therefore, we would have:

4x/2x = x + 1/x

Solve for x

2 = x + 1/x

2x = x + 1

2x - x = 1

x = 1

Height of figure 1 = 4x = 4(1) = 4 units.

The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Two dot plots are shown one below the other. The title for the top dot plot is Forearm Length, Group A and the title for the bottom plot is Forearm Length, Group B. Below the line for each dot plot is written Length followed by inches in parentheses. There are markings from 9 to 12 on each line at intervals of one. For the top line there are 3 dots above the second mark, 4 dots above the third mark and 3 dots above the fourth mark. For the bottom line there are 3 dots above the first mark, 5 dots above the second mark, and 2 dots above the third mark.

Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?

Group A, because seven children have a forearm length longer than 10 inches
Group B, because two children have a forearm length longer than 10 inches
Group A, because one child in the group has the least forearm length of 9 inches
Group B, because three children in the group have the least forearm length of 9 inches

Answers

Answer:

Group A, because seven children have a forearm length longer than 10 inches

Step-by-step explanation:

Create the dot plots based on the given information (please see attached images).

Group A = blue dots

Group B = red dots

From inspection of the attached dot plots, we can see that Group A appears to have the longer average forearm length.  This is because 7 children have a forearm length of longer than 10 inches.

To calculate the average forearm length, sum all data values and divide by the total number of data values.

[tex]\textsf{Average of Group A}=\dfrac{ 3 \times 10 + 4 \times 11 + 3 \times 12}{10}=11[/tex]

[tex]\textsf{Average of Group B}=\dfrac{ 3 \times 9 + 5\times 10+ 2\times 11}{10}=9.9[/tex]

Thus proving that Group A has the longer average former length.

According to given text data

Average of both groups

A:-

10(3)+11(4)+12(3)/1030+44+36/1066+44/10110/1011

B:-

Given the data from the question, the expressions that are equal to 10 are

10³ ⋅ 10²10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10

To determine the expressions that are equal to 10⁵, we shall evaluate the options given from the question.

How to evaluate (10⁴)¹

Recall

(Aᵐ)ⁿ = Aᵐⁿ

Thus,

(10⁴)¹ = 10⁴

How toevaluate 10³ ⋅ 10²

Recall

Aᵐ ⋅ Aⁿ = Aᵐ⁺ⁿ

Thus,

10³ ⋅ 10² = 10³⁺²

10³ ⋅ 10² = 10⁵

How to evaluate 1 / 10⁵

Recall

1 / Aᵐ = A⁻ᵐ

Thus,

1 / 10⁵ = 10

How to evaluate (10³)²

Recall

(Aᵐ)ⁿ = Aᵐⁿ

Thus,

(10³)² = 10

How to evaluate 10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10

Recall

Aᵐ ⋅ Aⁿ = Aᵐ⁺ⁿ

10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10 = 10¹⁺¹⁺¹⁺¹⁺¹

10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10 = 10⁵

SUMMARY

(10⁴)¹ = 10⁴

10³ ⋅ 10² = 10⁵

1 / 10⁵ = 10⁻⁵

(10³)² = 10⁶

10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10 = 10⁵

From the above illustrations, only 10³ ⋅ 10² and 10 ⋅ 10 ⋅ 10 ⋅ 10 ⋅ 10 are equal to 10⁵

Multiplicative

8/9 = 9/8

12/15 = 15/12

-6 = -1/6

10 = 1/10

Step-by-step explanation:

an additive inverse is a number you must add to another number to get 0

(think of it as the negative version of the number)

{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}

-2 + 2 = 0

18 - 18 = 0

-30 + 30 = 0

2/5 - 2/5 = 0

a multiplicative inverse is a number that you multiply by another number to get 1.

We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction

(reciprocal of 2 = 1/2  {remember, 2 is the same thing as 2/1 }   ; reciprocal of 1 / 8 = 8)

note: reciprocal is being used interchangeably with multiplicative inverse here

8/9 · 9/8 = 1

12/15 · 15/12 = 1

-6 · -1/6 = 1                     {-6  = -6/1}

10 · 1/10 = 1                    {10 = 10/1}

Each statement describes a transformation of the graph of y= x. Which statement correctly describes the graph of y= x+ 9.5?

a. it is the graph of y= x where the slope is increased by 9.5 .

b. it is the graph of y= x translated 9.5 units to the right.

c. it is the graph of y= x translated 9.5 units up.

d. it I'd the graph of y= x translated 9.5 units down.

Answers

Answer: C

Step-by-step explanation: The graph is going to go up because the +9.5 isn't in any parentheses. If it was, that would mean it would move horizontally. I hope this helps!

The correct statement:

It is the graph of y = x translated 9.5 units up.

The correct option is c.

The equation y = x represents a straight line passing through the origin with a slope of 1. When we have the equation y = x + 9.5, it means that for every x-value, the corresponding y-value is obtained by adding 9.5 to the original x-value. This translation in the y-direction shifts the entire graph upward by 9.5 units.

To visualize this, imagine the original line y = x. Each point on this line has an x-coordinate and a corresponding y-coordinate, which are the same due to the equation y = x. When we add 9.5 to each y-coordinate, the line shifts vertically by 9.5 units without any change in slope or horizontal position.

The other options can be eliminated because the statement does not mention changing the slope or the horizontal position of the graph. Instead, it specifically describes a vertical translation, indicating a movement in the y-direction. Therefore, the correct answer is c.

What is the approximate loudness of a dinner conversation with a sound intensity of 10–7?

Answers

The correct option is Option D: the approximate loudness of a dinner conversation will be 50Db with a sound intensity 10⁻⁷.

The loudness L, ( which is measured in decibels (Db)), of the sound of the intensity I, can be calculated in watts per square meter,

L = 10 log(I/I₀)  

where I₀ = 10⁻¹²  which is the least intensity that a human can hear.

The sound intensity of a dinner conversation= I= 10⁻⁷

Loudness L of that conversation = 10 log (10⁻⁷/10⁻¹²)

= 10 log(10⁻⁷⁻⁽⁻¹²⁾)

= 10 log(10⁻⁷⁺¹²)

= 10 log(10⁵)

= 10*5

= 50 Db

Domain and range of f(x)=3x^2-9x+8

Answers

The range of the function lies between (0,8) to (1.5,1.25).

What are domain and range?

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

The given function is:-

f(x) = 3x² -9x + 8

The value of the range will be from (0,8) to ( 1.5,1.25). When we plot the graph of the function the value of the range lies between the points (0,8) to ( 1.5,1.25). The graph is attached with the answer.

The domain of the function will be all the values of the real numbers for the function ranges from ( 0, ∞ ).

Therefore the range of the function lies between (0,8) to (1.5,1.25).

Explanation:

r = distance from the origin (0,0) to a point on the polar curve

To find the length of the flower petal, we need to max out r (i.e. get it as large as possible).

Recall that sin(x) maxes out at 1, so that also applies to sin(2θ) as well.

Therefore, r = 7*sin(2θ) maxes out at r = 7*1 = 7 and this is the length of each petal. Basically it's the number out front of the sine term.

Here the given angle is ∠BDC = 29 so from the given theorem the angle BEC will be equal to the angle BDC.

∠BDC = 29

The centre angle BOC will be twice the angle at the circumference so the angle will be twice.

Which statement compares the graph of the two functions?

First, a vertical shift of N units is written as:

if N > 0 the shift is upwards.If N < 0 the shift is downwards.

A horizontal shift of N units is written as:

g(x) = f(x + N).

if N < 0, the shift is to the right.If N > 0, the shift is to the left.

In this case, we have:

g(x) = f(x + 8) + 4

So g(x) is a shift of 8 units to the left and 4 units of f(x), then the correct statement is B.
