The vector perpendicular to a plane determined by two vectors A and B can be found by taking their cross product. The unit vector perpendicular to the plane determined by the vectors A and B is (-4/√56)i + (2/√56)j + (-6/√56)k.

A x B = (-2i+4j+0k) x (i+j-k)
= (-4k + 2i + 6j)

To find a unit vector perpendicular to the plane, we need to normalize this vector by dividing it by its magnitude:

|A x B| = sqrt((-4)^2 + 2^2 + 6^2) = sqrt(56)

So, a unit vector perpendicular to the plane determined by A and B is:

(-4k + 2i + 6j) / sqrt(56)

which simplifies to:

(-2i + 3j - k) / sqrt(14)

Therefore, the answer is (-2i + 3j - k).

To find a vector perpendicular to the plane determined by vectors A and B, you need to calculate the cross product of A and B.

A = -2i + 4j
B = i + j - k

Step 1: Calculate the cross product (C) of vectors A and B:
C = (A_y * B_z - A_z * B_y)i - (A_x * B_z - A_z * B_x)j + (A_x * B_y - A_y * B_x)k

Step 2: Plug in the values of A and B:
C = (4 * (-1) - 0 * 1)i - (-2 * (-1) - 0 * 1)j + (-2 * 1 - 4 * 1)k

Step 3: Simplify the expression:
C = -4i + 2j - 6k

Step 4: Find the magnitude of C:
|C| = √((-4)^2 + 2^2 + (-6)^2) = √(16 + 4 + 36) = √56

Step 5: Divide each component of C by its magnitude to find the unit vector:
Unit vector = (-4/√56)i + (2/√56)j + (-6/√56)k

So, the unit vector perpendicular to the plane determined by the vectors A and B is (-4/√56)i + (2/√56)j + (-6/√56)k.

Answer:

$16.48

Step-by-step explanation:

If 6% is sales tax, that means that the total cost of the doll is 106% of the original cost. (basically 100% is the originall doll, and you add 6% of the tax). If you convert 106% from percentage form to decimal form (which you do by dividing by 100), 106% is the same as 1.06 times the original cost of the doll.

Thus you do 1.06 x 15.55 = 16.483 which rounds down to $16.48

The function's y-intercept is 4, and the equation of its asymptote is y = 0. The graph shows that the function increases by a factor of [tex]\frac{3}{2}[/tex] each time x increases by 1. This function can be represented by the equation [tex]y = 4(\frac{3}{2})^x[/tex].

In Mathematics and Geometry, an exponential function can be modeled by using this mathematical equation:

[tex]f(x) = a(b)^x[/tex]

Where:

Based on the graph, we would calculate the value of a and b as follows;

[tex]f(x) = a(b)^x[/tex]

4 = a(b)⁰

a = 4

Next, we would determine value of b as follows;

6 = 4(b)¹

6 = 4b

b = 6/4

b = 3/2

Therefore, the required exponential function is given by;

[tex]y = 4(\frac{3}{2})^x[/tex]

In conclusion, the graph shows that the exponential function increases by a factor of [tex]\frac{3}{2}[/tex] or 1.5 each time x increases by 1.

What is a function?

A function is a mathematical relationship or rule that assigns a unique output value to each input value. It is a fundamental concept in mathematics and plays a central role in various branches, including calculus, algebra, and analysis.

To evaluate the given function at various values, we substitute the given values into the function and simplify the expression.

a. To find f(-3), we substitute -3 into the function: f(-3) = 2(-3)² + 7(-3) - 2 = 18 - 21 - 2 = 7.

b. To find f(a+3), we substitute a+3 into the function: f(a+3) = 2(a+3)² + 7(a+3) - 2. Expanding and simplifying the expression yields 2a² + 12a + 18 + 7a + 21 - 2 = 2a² + 19a + 37.

c. To find f(3a), we substitute 3a into the function: f(3a) = 2(3a)² + 7(3a) - 2. Simplifying the expression gives 18a² + 21a - 2.

d. To find f(a+h), we substitute a+h into the function: f(a+h) = 2(a+h)² + 7(a+h) - 2. Expanding and simplifying the expression yields 2a² + 4ah + 2h² + 7a + 7h - 2.

If there is a correlation between the number of employees and customer satisfaction in two different Buffalo Wild Wings stores, we need to perform a Pearson's correlation coefficient analysis.

To run stats testing on sales data from two different Buffalo Wild Wings stores, we need to use a correlation analysis. Specifically, we need to use Pearson's correlation coefficient to determine if there is a relationship between the number of employees and customer satisfaction. The Pearson's correlation coefficient ranges from -1 to +1, with -1 indicating a perfect negative correlation and +1 indicating a perfect positive correlation. If the coefficient is close to zero, it indicates that there is no correlation.
The data we need to collect includes the number of employees in each store and the sales data for a specific period. We also need to gather customer satisfaction data, which can be collected through surveys or other feedback mechanisms. Once we have the data, we can use a statistical software program like SPSS or Excel to perform the correlation analysis.
If the correlation coefficient is positive and statistically significant, it means that there is a relationship between the number of employees and customer satisfaction. This could mean that more employees lead to better customer service, which in turn leads to higher customer satisfaction and sales. However, if the correlation is negative or not statistically significant, it means that there is no relationship between the two variables.
In conclusion, to determine if there is a correlation between the number of employees and customer satisfaction in two different Buffalo Wild Wings stores, we need to perform a Pearson's correlation coefficient analysis. Gathering accurate data and using statistical software will allow us to determine if there is a significant relationship between the variables.

The value of x = -1 and y = -2 by solving the system of equation by using the substitution are 9x - y + 7 = 0 and 13x - 4y + 5 = 0

Given that,

The system of equation are 9x - y + 7 = 0 and 13x - 4y + 5 = 0

We have to solve the system of equation by using the substitution method.

We know that,

Take the system of equation

9x - y + 7 = 0 --------->equation(1)

13x - 4y + 5 = 0  ---------> equation(2)

From the equation (1)
9x - y + 7 = 0

y = 9x + 7

Substitute y = 9x + 7 in equation(2)

13x - 4y + 5 = 0

13x - 4(9x + 7) + 5 = 0

13x - 36x - 28 + 5 = 0

- 23x - 23 = 0

-23x = 23

x = -1

For a set of M elements, the number of combinations of N elements (N ≤ M) is given by:

In this case, we know that there is a room that can hold two of the girls, then the number of combinations of the two girls that can be in that room is:

So these are the different combinations for the larger room.

So we assume that two girls already have a room, then we have two girls left and two rooms left.

For the first room, there are two possible girls that can be in, let's choose one of them.

For the last room, we have only one girl left, so we have one option.

The total number of combinations will be equal to the product between the number of options for each event (where the events are assigning the girls to the rooms)

Then the number of different outcomes is:

C = 6*2*1 = 12

There are 12 different ways.

When we draw small and large samples from the same population, small samples produce a more peaked and narrower distribution.

This phenomenon is due to the presence of fewer degrees of freedom associated with the small samples. Variations between sample and population mean result in fewer degrees of freedom, which results in a greater variation between samples and the population mean.

Degrees of freedom (df) is a statistical measure that quantifies the number of values in the final calculation of a statistic that are free to vary. When we sample data from a population, we calculate the sample mean, standard deviation, and other statistics

To prove that lim x → 0 x^4 cos(2/x)=0, we need to show that for any ε > 0, there exists a δ > 0 such that |x^4 cos(2/x)| < ε whenever 0 < |x| < δ.

First, we note that -1 <= cos(2/x) <= 1 for all x. Therefore, we have:

x^4 <= x^4 cos(2/x) <= x^4 for all x

Taking the limit as x approaches 0 of both sides, we get:

lim x â 0 x^4 <= lim x â 0 x^4 cos(2/x) <= lim x â 0 x^4

Using the fact that lim x â 0 x^4 = 0, we can conclude that:

0 <= lim x â 0 x^4 cos(2/x) <= 0

Thus, by the squeeze theorem, we have:

lim x â 0 x^4 cos(2/x) = 0
