Answer:

See attached photograph

Step-by-step explanation:

It is a simple matter of subtracting 1 from the given x value. For example, when x=3 we need to subtract 1 away from it to find f(x); so, f(x)=2.

Side note: the term "f(x)" means "y", so when plotting this information on a graph, you will use the f(x) column as your y value.

Find the slope of the line that passes through the points (9, -2) and (-3. -2). Write the equation in
slope-intercept form.

Answers

Answer:

slope: zero/none

equation: y = -2

Step by Step:

1) find the slope - change in y / change in x

-2+2/9+3

0/12

0 <- zero slope = no slope

2) plug in and solve for y-intercept

( -3, -2 )

-2=(0*-3)+b

b=-2

because the slope was zero, we know that it's a horizontal line

therefore the only equation we can get from this is a y= equation

3) plug in values to get equation

y = -2

slope is zero

A fierce guard dog is tethered by a 15 m chain to a post that is 6 m from a straight path. For what distance along the path is a trespasser in danger from the dog?​

Answers

The distance from the road where an intruder would be in danger is 27.48 m.

To know how far from the road an intruder is in danger due to the dog, it is necessary to carry out the following procedure:

Establish the range of the dog with a circle of 15 meters in radius around the post on which he is tied.

In this part it can be inferred that a part of the path is in the range of the dog between points B and D (In this area the intruder would be in danger)

From this we know the following data:

Length AB = 15mLength AD = 15mLength AC = 6m

To know the length of points BC and CD we must perform a calculation using the formula of the Pythagorean theorem.

BC = [tex]\sqrt{15^{2} - 6^{2} }[/tex]BC = [tex]\sqrt{225-36}[/tex]BC = [tex]\sqrt{189}[/tex]BC = 13,74 m

Later we use the same procedure to find the length CD.

CD = [tex]\sqrt{15^{2} - 6^{2} }[/tex]CD = [tex]\sqrt{225-36}[/tex]CD = [tex]\sqrt{189}[/tex]CD = 13,74 m

Finally, we add both lengths (BC + CD) to know the distance in which an intruder is in danger within the dog's range.

BC + CD = BD = 27,48 m

[tex]x=\pm \sqrt{21}/7[/tex]

Step-by-step explanation:

We can add 9 to both sides of the equation to get [tex]21x^2=9[/tex].

We can divide both sides of the equation by 21 to get [tex]x^2=9/21[/tex].

We take the square root of both sides of the equation to get [tex]x=\pm \sqrt{9/21}[/tex].

However, that isn't in the form we need.

We know that [tex]\sqrt{9/21}=\sqrt{9}/\sqrt{21}=3/\sqrt{21}=3\sqrt{21}/(\sqrt{21}*\sqrt{21})=3\sqrt{21}/21=\sqrt{21}/7[/tex]

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.

(-6, 2)

(-2, -6)

(-1, 8)

(4,6)

if it is a valid function.

At NO point should a function have multiple x values. This fails the Vertical Line Test if visualized on a graph.

For Part A, there are no duplicate x values, meaning this function is valid.

For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, PERIOD. If graphed, it fails the vertical line test.

In a hypothetical population of butterflies, a dominant mutation in an allele that controls wing color has resulted in purple spots developing on the wings. The genetic change is heritable such that the offspring of butterflies who inherit at least one mutated allele will develop purple spots. The population of butterflies inhabits a windy field that contains many purple flowers. Individuals with purple spots are so well camouflaged on the purple flowers that they are eaten less frequently by predators. There are other fields with populations of the same species of butterfly nearby, but purple flowers are less prevalent in these nearby habitat areas. There are no borders between these fields and it is common for individuals from one population to be blown into another population by the wind. Despite the advantage the mutated allele confers to the butterflies in the field with many purple flowers, the mutated allele never occupies 100% of the gene pool and the population of butterflies always contains a mix of individuals with and without purple spots.
