What happens to the x and y coordinates in a 90-degree counterclockwise rotation?

Answers

Answer 1

Answer: hope this helps i didnt see any A, B, C, D etc options to choose from

each point of the given figure has to be changed from (x, y) to (-y, x)

Step-by-step explanation:

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.

Example 1 :

Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. If this triangle is rotated 90° counterclockwise, find the vertices of the rotated figure and graph.

Solution :

Step 1 :

Here, triangle is rotated 90° counterclockwise. So the rule that we have to apply here is

(x, y) -------> (-y, x)

Step 2 :

Based on the rule given in step 1, we have to find the vertices of the rotated figure.

Step 3 :

(x , y) -----> (-y , x)

F(-4 , -2) -------> F'(2, -4)

G(-2, -2) -------> G'(2, -2)

H (-3, 1) -------> H'(-1, -3)

Step 4 :

Vertices of the rotated figure are

F'(2, -4), G'(2, -2) and H'(-1, -3)

Why is y=3 a polynomial function?

Answers

Answer: y=3 is a polynomial function? Yes. The equation y=3 represents the function that maps all x values to 3

Step-by-step explanation:

The equation y= 3 represents a horizontal line, which will have exactly one intersection point with any vertical line. So it passes the vertical line test for a function too.

The circle graph shows the results of a survey. Of those surveyed, 200 said yes. About how many people were surveyed?

Answers

Answer:

250 people

Step-by-step explanation:

let's first look for the missing 20%,

one way you can solve this is by cross multiplication:

since 80% is 200 then 80% = 200

and we know 20% is x then 20% = x (we use x because we don't know the amount of people)

so then we set it up:

[tex]\frac{x}{20}[/tex] × [tex]\frac{200}{80}[/tex]

now we cross multiply:

80x = 4000

= x = 50

now we need to find how many people were surveyed so we do:

200 + 50 = 250

250 people were surveyed

4. Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the
week beforeThis is a result of...
Sunk cost

Overconfidence

Endowment effect

Answers

Answer:

Endowment effect

Step-by-step explanation:

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

This is a result of the endowment effect.

Given,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

We need to find whether it is a result of

- Sunk cost

- Overconfidence

- Endowment effect

What are the endowment effect and Sunk cost?

The endowment effect is the effect of placing a higher value on an object

they own than the value on the same object they did not own.

The sunk cost is a cost that has already been incurred and that cannot be

recovered.

We have,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

Here,

We are talking about the same item $20.

Losing $20 is losing what Michael owns.

Finding $20 on the sidewalk is not what Michael owns.

And the pain of losing $20 which he owns is more than the joy of finding it on the sidewalk so,

The Endowment effect is found here.

Thus,

Michael observed he felt the pain of losing a $20 bill more than he felt the joy of finding it on the sidewalk the week before.

This is a result of the endowment effect.

-8 is a negative number, which means many operations don't work the same on it. Subtracting a positive number from a negative number will give you the same result as adding the two positive numbers (in this case, 8 + 9), though the answer will also be negative. Hope this helps!
