What are the solutions to the equation x2 = 64

Answer: 5

Step-by-step explanation:

Range = highest value - lowest value

The highest value from the data set given = 1

The lowest value = -4

Therefore :

Range = 1 - (-4)

Range = 1 + 4

Range = 5

The correct answer is: When triangle ABC is translated 2 units to the left and 1 unit down to create triangle A'B'C' , the coordinates for B' are (-1, 0). The true statement is D.

Let's analyze each statement:

A; When triangle ABC is reflected over the y-axis to create triangle A'B'C' , the coordinates for B' are (1, -1) .

To reflect over the y-axis, the x-coordinate changes sign while the y-coordinate remains the same. If the coordinates for B are (x, y), then after reflecting, the x-coordinate becomes -x. Since B has coordinates (1, 1), after reflection, B' will have coordinates (-1, 1). So, statement A is false.

B; When triangle ABC is rotated 90 degrees clockwise about point A to create triangle A'B'C' , the coordinates for B' are (3,3]

Rotation of 90 degrees clockwise about a point involves swapping x and y coordinates and negating the new x-coordinate. The point A is not given, but assuming it's (0, 0), if B has coordinates (x, y), then after rotation, B' will have coordinates (y, -x). If A is (0, 0) and B is (3, 1), after rotation, B' will have coordinates (1, -3), not (3, 3). So, statement B is false.

C; When triangle ABC is dilated from the origin by a scale factor of 1/4 to create triangle A'B'C', the coordinates for B' are (4,4)

Dilating by a scale factor of 1/4 means multiplying each coordinate by 1/4. If B has coordinates (x, y), then after dilation, B' will have coordinates (1/4 * x, 1/4 * y). Since B has coordinates (4, 4), after dilation, B' will have coordinates (1, 1). So, statement C is false.

D; When triangle ABC is translated 2 units to the left and 1 unit down to create triangle A'B'C' , the coordinates for B' are (-1, 0)

Translation involves adding/subtracting values to x and y coordinates. If B has coordinates (x, y), then after translation by (-2, -1), B' will have coordinates (x - 2, y - 1). Since B has coordinates (1, 1), after translation, B' will have coordinates (-1, 0). So, statement D is true.

E; When triangle ABC is dilated from the origin by a scale factor of 5 to create triangle A'B'C', the coordinates for B' are (5,5)

Dilating by a scale factor of 5 means multiplying each coordinate by 5. If B has coordinates (x, y), then after dilation, B' will have coordinates (5 * x, 5 * y). Since B has coordinates (4, 4), after dilation, B' will have coordinates (20, 20), not (5, 5). So, statement E is false.

So, the true statement is D.

Answer:

The migration of the African-Americans to Harlem in the USA empowered the African-Americans in the society in the early 1900s. This was one of the greatest accomplishments of the African-Americans in history.

Explanation:

The "Harlem Renaissance" was originally called the "New Negro Movement." During the "Reconstruction Era," many of the African Americans felt a newfound empowerment in the society. They started leaving the South, where most of them were enslaved and maltreated. Many of them moved to other places such as "Harlem" in New York City. It became an ideal destination for many "Negros" and their number increased over time. This then became an African-American neighborhood.

African-Americans started producing plays with actors of their descent. Several Negro poets emerged describing the life of the African-Americans. Negros became more literate and able when it comes to expressing themselves in the society. They even had their own newspaper known as "The New Negro Movement."

Answer:

Step-by-step explanation:

total capacity = 62.5 GB

available capacity = 35.0 GB

35 is what percent of 62.5

35 = x% * 62.5

35 / 62.5 = x%

0.56 = x%

56% = x <=====

56% of the memory capacity is still available.

To calculate the percentage of memory capacity that is still available, we can use the available capacity and total capacity information provided.

Given:

Capacity: 62.5 GB

Available: 35.0 GB

To find the percentage, we divide the available capacity by the total capacity and multiply by 100:

Percentage = (Available / Capacity) x 100

Percentage = (35.0 GB / 62.5 GB) x 100

Percentage ≈ 56%

Therefore, 56% of the memory capacity is still available.

Answer:

Ms. Griffiths lives on 3rd floor

Step-by-step explanation:

The elevator moves 10.2 seconds from one floor to another and stops for 45.8 seconds for people to exit. Thus, add: 10.2 seconds + 45.8 seconds = 56 seconds

If it takes her 158 seconds to travel from the lobby to her apartment, then 158 seconds/56 seconds = 2.8 = 3 (approximately).

Therefore, she lives on 3rd floor.

Mathematically, the values ought to be 168 seconds /56 seconds = 3.

The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3

Step-by-step explanation:

A symptote is a line that a curve approaches but never touches

∵ f(x) = 3 ㏒(x + 3)

∵ The argument is (x + 3)

- Equate the argument by zero

∵ x + 3 = 0

- Subtract 3 from both sides

∴ x = -3

- The vertical asymptote of a logarithmic function is at the zero

  of the argument

∴ The vertical asympotote of f(x) is x = -3

The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3

Answer:

x = 9

Step-by-step explanation:

Determine the defined range

[tex]log^6 (4x^2) - log^6 (x) = 2, x = (0, + ∞)[/tex]

Use log^a (x) - log^a (y) = log^a (x/y) to simplify the expression

[tex]log6 (\frac{4x^{2} }{x} )= 2[/tex]

Simplify the expression

log^6 (4x) = 2

Convert the logarithm into an exponential form using the fact that log^a (x) = b is equal to x = a^b

[tex]4x=6^{2}[/tex]

Evaluate the power

4x = 36

Divide both sides of the equation by 4

x = 9, x = (0, + ∞)

Answer:

[tex]\frac{7}{12}[/tex]  of an hour is remaining for Mariko's social studies class

Step-by-step explanation:

Given:

Total duration of Mariko's social studies class = 5/6 of an hour.

Only 3/12 of an hour has passed.

To Find:

Fraction of an hour remains for Mariko's social studies class =?

Solution:

Converting into minutes

5/6 of an hour =  [tex]\frac{5}{6} \times (60)[/tex]

=>[tex]\frac{300}{6}[/tex]

=>50 minutes

So the total duration of  Mariko's social studies = 50 minutes

If  3/12 of an hour passes means

Converting into  minutes

=>[tex]\frac{3}{12} \times 60[/tex]

=>[tex]\frac{180}{12}[/tex]

=>[tex]\frac{180}{12}[/tex]

=> 15 minutes

15 minutes has passed

Remaining time left is

50 minutes - 15 minutes = 35 minutes left

Now converting into 35 minutes into hours we get

=> [tex]\frac{35}{60}[/tex]

=>[tex]\frac{7}{12}[/tex]

Subtracting the time passed from the total class time gives us the remaining time. The calculation involves simplifying the time passed fraction and finding a common denominator to subtract fractions. In the end, we find that 7/12 of an hour remains for Mariko's social studies class.

This is a question about subtracting fractions to calculate remaining time. Mariko's social studies class lasts 5/6 of an hour and 3/12 of an hour has passed. To find out how much time remains, you need to subtract the time that has passed from the total class time.

First, you simplify the fraction of the time that has passed. 3/12 simplifies to 1/4, since 3 and 12 are both divisible by 3.

Then, you subtract 1/4 from 5/6 to calculate the time remaining. To do this, you need to find a common denominator, which is 12 in this case.

Converting 5/6 and 1/4 into twelfths gives you the fractions 10/12 and 3/12 respectively.

Then, subtract 3/12 from 10/12 which is 7/12.

So, the answer is 7/12 of an hour remains for Mariko's social studies class.
