Step-by-step explanation:

Is the second exponent 6, or 6x ?

If it is 6x, then x = -½

Answer:

6x^2 -9

Step-by-step explanation:

1. From the table, you know that when x = 0, y = -9, this means that the initial value is -9. This means that the last option is not correct

*** y values -> output

2. Plug in a x - value from the table to figure out the right rule:

x = 2

First option: 6x - 9 -> 6*2 - 9 = 12-9 = 7

in the table, the output for x =2 is 15 so the first option is not correct

Second option: 6x^2 - 9 -> 6*(2^2) - 9 = 6*4 - 9 = 24 - 9 = 15

in the table, the output for x =2 is 15 so the second option is correct

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

The most appropriate choice for equation of line in slope intercept form will be given by-

\(8x - 5y = 26\) is the required equation of line.

What is equation of line in slope intercept form?

General form of equation of line in slope intercept form is given by

y = mx + c where m is the slope of the line and c is the y intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept

The distance from the origin to the point where the line cuts the x axis is the x intercept

Here,

\(8x - 5y = 4\\5y = 8x - 4\\y = \frac{8}{5}x - \frac{4}{5}\)

Slope of \(8x - 5y = 4\) is \(\frac{8}{5}\\\)

Slope of the line parallel to the given line = \(\frac{8}{5}\)

The line passes through (2, -2)

Equation of line =

\(y - (-2) = \frac{8}{5}(x - 2)\\5y + 10 = 8x -16\\8x - 5y = 16+10\\8x - 5y = 26\)

Answer:

  -5 < x-1 < 5

Step-by-step explanation:

Consider |a|. This has the value -a when a < 0. So, if we write the inequality ...

  |a| < b

it is equivalent to two inequalities:

  a < b . . . . for a ≥ 0

  -a < b . . . for a < 0

Multiplying by -1. the latter inequality is ...

  a > -b . . . for a < 0

Written using the < symbol, this is ...

  -b < a

So, the original inequality can be written as the two inequalities ...

  -b < a (for a < 0)   or   a < b (for a ≥ 0)

Since these are disjoint, we can form their union as ...

  -b < a < b

__

Above, we have a = x-1, b = 5, so the inequality |x-1| < 5 can be written ...

Step-by-step explanation:

To find the slope between two points, we can use the slope formula. The slope formula is:

\(m=\frac{y_2-y_1}{x_2-x_1}\)

where m is the slope and (x₁, y₁) and (x₂, y₂) are two points.

By plugging in (5, 4) and (5, 9) for (x₁, y₁) and (x₂, y₂) respectively, we get:

\(m=\frac{9-4}{5-5}=\frac{5}{0}\)

Note, we cannot divide by zero. By using the slope formula, we get that the slope is undefined.

To determine the values of a and b in the relative frequency table, we need to analyze the information provided in the Venn diagram and the given table.

From the Venn diagram, we can gather the following information:

The circle labeled "satellite" has a value of 55.

The circle labeled "cable" has a value of 75.

The overlap between the two circles is labeled as 12.

Using this information, we can complete the table:

First column - "Satellite":

Entries: Satellite, Not satellite, Total

Total: 55 (as given in the Venn diagram)

Second column - "Cable":

Entries: Blank, 51%, Blank

To find the value for the "Cable" entry, we need to subtract the overlap (12) from the total number of cable users (75).

Cable: 75 - 12 = 63

Therefore, the entry becomes: Blank, 51%, Blank

Third column - "Not Cable":

Entries: a, b, Blank

To find the value for "a," we subtract the overlap (12) from the total number of satellite users (55).

a: 55 - 12 = 43

To find the value for "b," we subtract the overlap (12) from the total number of households (100).

b: 100 - 12 = 88

Therefore, the entries become: 43, 88, Blank

Fourth column - "Total":

Entries: Blank, Blank, 100%

The total number of households is given as 100% (as stated in the question).

Therefore, the values of a and b in the relative frequency table are:

a = 43% (rounded to the nearest percent)

b = 88% (rounded to the nearest percent)

Hence, the correct answer is:

a = 43%

If Point A is located at (1, 2) and Point B is located at (4, 6), the length of the line between points A and B is 5 units.

To determine the length of the line between points A and B, we can use the distance formula, which is a formula used to calculate the distance between two points in a coordinate plane. The distance formula is:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points and d is the distance between them.

Using the coordinates of points A and B, we can substitute their values into the distance formula to find the length of the line between them:

d = √((4 - 1)² + (6 - 2)²)

d = √(3² + 4²)

d = √(9 + 16)

d = √25

d = 5

Rounded to the nearest whole number, the length of the line is also 5 units.

In conclusion, we can use the distance formula to find the length of the line between two points in a coordinate plane. The distance formula uses the coordinates of the two points to calculate the distance between them. The resulting distance can be rounded to the nearest whole number, if needed.

No. The reported return rate appears lower than expected.

To determine whether the reported rate of return is reasonable or not, we can calculate the expected rate of return based on the investment amount and the ending value of the account.

First, we need to calculate the total number of quarters that have elapsed between the initial investment and the current quarter. Let's assume that the investment has been held for n quarters.

Then, we can use the following formula to calculate the expected rate of return:

Expected rate of return = (Ending value / Initial investment) ^ (1/n) - 1

Plugging in the given values, we get:

n = 1 (since we are only given information for a single quarter)

Initial investment = 26,245

Ending value = 26,292

Expected rate of return = (26,292 / 26,245) ^ (1/1) - 1 = 0.18%

Comparing the expected rate of return of 0.18% with the reported rate of return of -0.02%, we can see that they are quite different. However, it's important to note that a single quarter's rate of return may not be indicative of the overall performance of the investment.

Therefore, while the reported rate of return seems lower than expected, we would need to consider the performance over a longer period of time to make a more informed assessment of the investment's performance.

To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get \(r=\frac{a_{n}}{a_{n-1}}\)). If we take 24 and divide it by 16, we get the common ratio of 3/2 (\(r=\frac{24}{16}\), \(r=\frac{3}{2}\)). Hope this helps.
