82 - 2i

Step-by-step explanation:

(5 - 2i) + (-4 + 81)

5 - 2i + 77

= 82 - 2i

1 + 6i

we open the brackets to give us

5 - 2i - 4 + 8i

collecting like terms, we have,

-2i + 8i + 5 - 4

6i + 1

Answer:

By the end of this resource, you will be able to identify domain and range from any given contextual situation.  

Determining the domain and range from a linear or quadratic contextual situation is similar to determining the independent and dependent variables.

Step-by-step explanation:

Suppose you are interviewing for a job. Your employer offers you the choice of two different options for your pay. The first option is to pay you $10.00 per hour and give you a raise of $.50 per hour at the end of the year. The second option is to pay you $11.50 per hour and give you a raise of $.25 per hour at the end of the year.

First, find a function for each option. To do that, you have to know what the domain and range might be. Let y = the amount you will make at the end of the year and x = the number of hours you work. Thinking about what would be reasonable values for x and y will help determine the domain and range.

First, let's think about the domain. Since x represents the numbers of hours you worked for the year, would it be reasonable to have negative values? If you said NO, you would be correct. We can assume the lowest possible value in the domain would equal zero. So, our domain would be {x| x ≥ 0}.

Now, let’s think about the range. Since y represents your earnings at the end of the year, would it be reasonable to have negative values? If you said NO again, you would be correct. You cannot earn a negative amount. We can assume the lowest possible value in the range would also equal zero. So, our range would be {y | y ≥ 0}. You should be able to relate with this situation since you may have to make a decision in comparing two or more job offers in your future.

It's important to realize that every situation is different and you must think about what is reasonable.

The domain is the travel on the x-axis of the graph and the range is the travel on the y-axis of the graph.

First, according to the information, we build a linear model, and then, the model is used to find the information asked.

a) The linear model is:

[tex]V(t) = 224000 - 6800t[/tex]

b) The depreciated value of the boat after 10 years is of $156,000.

c) The depreciated value falls below $100,000 after 18.24 years.

d) The sketch is given at the end of the answer.

Item a:

[tex]m = \frac{115200 - 224000}{16} = -6800[/tex]

Then, the linear model is:

[tex]V(t) = 224000 - 6800t[/tex]

Item b:

The value after 10 years is V(10), so:

[tex]V(10) = 224000 - 6800(10) = 156000[/tex]

Then, the depreciated value of the boat after 10 years is of $156,000.

Item c:

This is t for which: V(t) = 100000. So

[tex]V(t) = 224000 - 6800t[/tex]

[tex]100000 = 224000 - 6800t[/tex]

[tex]6800t = 224000 - 100000[/tex]

[tex]6800t = 124000[/tex]

[tex]t = \frac{124000}{6800}[/tex]

[tex]t = 18.24[/tex]

The depreciated value falls below $100,000 after 18.24 years.

1) The product of slope of two perpendicular lines is-1 .

2) The slope of two parallel lines is same .

Given two lines to us are ,

This line is in slope intercept form which is [tex] y = mx + c [/tex] . Comparing to which we get ,

Again , the second line given to us is ,

Convert it into slope intercept form , we have ,

Answer:

10 headbands = $12.50

Step-by-step explanation:

1) The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is: S = 1.25 * x. For each headband sold, you earn a commission of $1.25.

2) The point (5, 6.5) is not a solution for the function. When you sell 5 headbands, the commission earned should be $6.25, not $6.5.

3) A solution that does not appear in the table is (10, 12.50). Selling 10 headbands would result in a commission of $12.50.

1.

To complete the table, we can use the given information that for each headband sold, you earn a commission of $1.25.

Function Rule (Commission S): The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is:

S = 1.25 * x

Now, we can use this function to fill in the table:

Number of Headbands Sold (x) | Commission (S)

0 | 0 * 1.25 = $0 (No commission earned for 0 headbands sold)

1 | 1 * 1.25 = $1.25

2 | 2 * 1.25 = $2.50

3 | 3 * 1.25 = $3.75

7 | 7 * 1.25 = $8.75

15 | 15 * 1.25 = $18.75

32.50 | 32.50 * 1.25 = $40.625 (The value in the table seems to be a typo, it should be 32.50 * 1.25 = $40.625)

2.

To check if (5, 6.5) is a solution for the function, we need to see if the commission earned (S) matches with the given number of headbands sold (x) for that point.

Given (x, S) = (5, 6.5)

Using the function rule: S = 1.25 * x

S = 1.25 * 5 = 6.25

The commission earned (S) is $6.25, not $6.5. Therefore, (5, 6.5) is not a solution for the function as the value of S does not match.

3.

To identify a solution that does not appear in the table, we can select any number of headbands sold (x) and calculate the corresponding commission (S) using the function rule.

For example, let's choose x = 10:

Using the function rule: S = 1.25 * 10 = $12.50

So, a solution that does not appear in the table is (10, 12.50), where 10 headbands sold results in a $12.50 commission.

You are rotating the the triangle 180 degrees about the origin. The rule for that is (x,y) ----> (-x,-y)

So X starts at (-4,1) and rotates until it hits (- - 4, -1 or (4,-1). Question is that where X' is? Yes.

Now try the next two points

W(-3,-4) ------> W'(- - 3, - -4) = W'(3,4)

Y(-1,-2) =====> y'(- - 1 , - - 2) = Y'(1,2)

Is that where these points are? Yes it is

This given triangle GFH rotates 90 anticlockwise. The rule for that (x,y) ===>(-y,x)

This means that you interchange x and y and make the y value minus. All you have to do is obey the rule.

F(-3,0) becomes F'(0,-3)

G(4,0) becomes G'(0,-4)

H(-3,3) becomes H'(-3,-3)

Answer:

  10) (x, y) ⇒ (-x, -y) . . . . rotation 180° about the origin

  12 (x, y) ⇒ (-y, x) . . . . . rotation 90° CCW about the origin

Step-by-step explanation:

10) The order of the points WXY is CW in both figures, so no reflection (or an even number of reflections) across a line will be involved. Each image point is the same distance from the origin as its preimage point, so no dilation is involve. Those distances are in opposite directions, so rotation 180° about the origin is indicated.

The transformation describing that is ...

12) The order of points GHI is CW in both figures, so reflection across a line is not involved. Each image point is the same distance from the origin as its preimage, so no dilation is involved. The direction from the origin is different by 90°, so there has apparently been a 90° CCW rotation about the origin. This transformation is described by the rule ...
