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.

What is a Turning Point of a Function?

The turning point of a function is defined as the point where the graph of the function changes it's form. That is, an increasing graph changes to decreasing at that point and vice versa.

Given a table values of function.

Also, given that, one of the turning point is at x = -1.

At x = -1, f(x) = 4.

After it, the function decreases.

We can also see another turning point at x = 1.

At x = 1, f(x) = -4.

After x = 1, the function again increases to get the value f(x) = -2.

So x = -2 is not a turning point.

So the value of f(-2) = m lies in between -12 and 4.

Hence the correct option is B.

Answers

Answer:

85 degrees

Step-by-step explanation:

1) say you are given the graph of the line y =- x write the equation of the line that is parallel to the given line and goes through the point (-8,2)
2) say you are given the graph of the line y =- x write the equation of the line that is parallel to the given line and goes through the point (8,2)

Answers

I'm pretty sure the answer to y=−x. Write equation for (8,2) is y=x-6. The opposite of the x is -8, hence, (-8,2) is y=-x-6 is the answer

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

What is Equation of line?

The equation of the line in slope-intercept form is expressed as:

y - y₁ = m(x - x₁)

where: m is the slope.

and (x₁, y₁) is the point on the line.

1. Given that;

Equation of the line as y = -x

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - (-8) )

y - 2 = x + 8

y = x + 8 + 2

y = x + 10

Hence, The equation of the line which is parallel and goes through the point (-8, 2) is,

⇒ y = x + 10

2.  Given that;

Equation of the line as y = -x

Point as (8, 2)

Get the slope of the line,

y = -x

m = -1

Since, The required line is parallel to this line,

So, the required slope will be -1

Now, Get the required equation as,

y - y₁ = m(x - x₁)

y - 2 = 1 ( x - 8 )

y - 2 = x - 8

y = x - 8 + 2

y = x - 6

Hence, The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

Thus,

1. The equation of the line which is parallel and goes through the point (-8, 2) is,

y = x + 10

2. The equation of the line which is parallel and goes through the point (8, 2) is,

⇒ y = x - 6

   - To make it slope-intercept form

   y - 4 = 0.8x - 1.6

   y = 0.8x + 2.4

5. (Use slope finding formula) 4 - 10 / -2 - (-5) = 2

   y - 4 = 2(x + 2)

Point A lies on a number line at 6. Point C lies between points B and A at 1.875. The ratio AC : AB = 3 : 5. What is the length of A B?

A. AB = 15 units
B. AB = 8.75 units
C. AB = 6.875 units
D. AB = 11 units

Plz Answer ASAP! Thank you!

Answers

Answer: C, 6.875 is the correct answer

Step-by-step explanation:

AC = 6 - 1.875 = 4.125

AB = 5/3 * 4.125 = 6.875

The measure of AB is 6.875. Therefore, option C is the correct answer.

Given that, the ratio AC: AB = 3: 5.

What is the ratio?

In mathematics, a ratio indicates how many times one number contains another.

AC = 6 - 1.875 = 4.125

AB = 5/3 * 4.125 = 6.875

Therefore, option C is the correct answer.
