2. The hypothetical market for flu shots is depicted in the graph below where market equilibrium quantity is 20 flu shots and market equilibrium price is $20 per shot. Assume that there was an external benefit of $20 per flu shot (value of the flu shot by an individual that accrues to bystanders). What would be the socially optimal quantity of flu shots considering the effect of this external benefit? Answer = ____ flu shots How much of a subsidy per shot would make the market equilibrium outcome be equal to the socially optimal equilibrium? Answer = $____ per flu shot (/2.0 Points)

Answer

Options A, D and E are correct.

The two functions are increasing.

The function for plan II has a greater unit rate.

The function for plan I has a greater y-intercept.

Explanation

The slope and y-intercept form of the equation of a straight line is given as

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

For the first plan, there's a one time investment of 15,000 dollars and subsequent monthly payments of 500 dollars.

y = 15,000 + 500x

y = 500x + 15,000

Slope = unit rate of increase = 500

y-intercept = 15,000

For the second plan, the function is just given as

y = 12,000 + 520x

y = 520x + 12,000

Slope = unit rate of increase = 520

y-intercept = 12,000

We can see that

The two functions are increasing.

The function for plan II has a greater unit rate.

The function for plan I has a greater y-intercept.

Considering the definition of a line, the equation in slope-intercept of the line that passes through the point (1, 10) and has a slope of 1 is y=x+9.

A linear equation o line can be expressed in the form y = mx + b

where

In this case, you know:

Substituting the value of the slope m, the line has a form: y=1x + b or what is the same y=x +b.

Replacing the value of the point in the expression of a linear equation, the value of the ordinate to the origin b can be obtained:

10= 1×1 + b

10= 1 + b

10 -1 = b

9= b

Finally, the equation of the line is y=x +9.

Answer the point-slope form of the equation below that represents the line that passes through the point (6, -3) and has a slope of 1/2

A linear equation can have the form

y = mx + b

The slope is m

The point-slope form is

(y- y1) = m(x -x1) (1)

the point (x1, y1) = (6, -3)

______________

Replacing in (1) the slope and the point (x1, y1)

(y- y1) = m(x -x1)

(y- (-3)) = 1/2(x -6)

y+3 = 1/2(x-6)

__________________

So, checking the options the correct answer is C

A.) y-6 = 1/2(x+3)

B.) y = 1/2x - 6

C.) y+3 = 1/2(x-6)

D.) y-2y = 12

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient so equation of line d is y = -5x + c.

Substitute (2,-6) into the equation to find c.

-6 = -5(2) + c

c = 4

Hence equation of line d is y = -5x + 4.

The estimate (to one decimal place) of the average rate of change f is 2.3

The interval is given as

[-1, 2]

This can be rewritten as

x = -1 to x = 2

This can also be represented as

(a, b) = (-1, 2)

From the attached graph, we have

f(-1) = -5

f(2) = 2

The estimate (to one decimal place) of the average rate of change f is

Rate = [f(b) - f(a)]/[b - a]

This gives

Rate = [f(2) - f(-1)]/[2 + 1]

So, we have

Rate = [2 + 5]/[2 + 1]

Evaluate

Rate = 2.3

Hence, the average rate of change f is 2.3

Answer: Jenny = 6 | Kim = 7 | (Unknown Sister because no name) = 44

Step-by-step explanation:

Jenny = 6 years (that we already know)

6 x 2 = 12 - 5 = 7 years for Kim

7 + 6 = 13

To find the unknown age of the last sister, we will subtract 57 - 13 = 44

So the last sister is 44.

(I am very sorry if this is wrong, I am only in Middle School).

The percentage increase or decrease can be calculated by :

7. New = 13, Orig = 10

% change = [(13 - 10)/10] x 100 = 30% (Increase)

8. New = 3, Orig = 5

% change = [(3 - 5)/5] x 100 = -40% or 40% (decrease)

If angle 5= 42° and angle 1 = 117°

angle CDF = angle 5 + angle 1

=42° + 117°

=159°

The rule of the slope of a line has 2 points is

A = (1, -2), B = (3, 4), C = (-2, 6)

We will take the altitude from A to the opposite side of BC

Then we will find the slope of BC first

x1 = 3 and y1 = 4. point B

x2 = -2 and y2 = 6. point C

We will substitute them in the rule above

The slope of BC = -2/5

Since the product of the slopes of the perpendicular line is -1, then if the slope of one is m, then the slope of the other will be -1/m, we reciprocal it and change its sign, then the slope of the altitude of BC should be 5/2

The form of the equation in point-slope is

y - y1 = m(x - x1)

m = 5/2

Since point A is lying on the altitude from A to BC, then

x1 = 1 and y1 = -2 point A

Substitute m and coordinates of point A in the form of the equation above

y - (-2) = 5/2 (x - 1)

The equation of the altitude from A to BC is

y + 2 = 5/2 (x - 1)

To get the product we multiply.

[tex] = 5 \times y \\ = 5y[/tex]

Fron the information, it as stated that a year is called "nice" if its number can be represented as the difference of two powers of two.

The next nice year will be the difference which will be

Solution:

Given the graph;

If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, the curve does not represent a function.

ANSWER: B

From the graph, the range of the function in the graph is; 0 ≤ M ≤ 6.5

The range of a function is the set of all possible output values for which the function still exists.

Now, from the graph, we can see that it is a linear graph that starts on the vertical axis with a coordinate of approximately (0, 1) which denotes 1 kg when the volume is 0 liters.

Now, we see that the line of the graph stops at the coordinate (7.5, 6.5) which denotes 6.5 kg when the volume is 7.5 liters.

Therefore the maximum mass is 6.5 kg while the minimum is 0 kg. Thus,;

Let's talk a little about the simplest radical form of a square root

The first step to finding it is to write the number within the root as a product of prime powers, such product is called its integer factorization. Let's do that for 24:

Then, the integer factorization of 24 is

Thus,

The idea now is to take out of the root all we can. The rule is that we can only take out powers of 2 (for our root is a square root). In the expression

There is only one power of 2, within 2^3. We can write it as

How are we going to take out it? We are going to take out the base of the power, which is 2 in this case. Then,

In simple terms, the simplest radical form of a root is what results after taking out the root all that can be taken out.

Slope intercept form:

y = mx + b

m = (y2 - y1)/(x2 - 1) = (-8 - 1)/(2 - (-1)) = -9/(2 + 1) = -9/3 = -3

m = -3

If we take one of the point, for example (2, -8) and use it on the equation with the slope we already found:

y = -3x + b

-8 = -3(2) + b

Solving for b:

-8 = -6 + b

b = -8 + 6 = -2

b = -2

Therefore, the equation is: y = -3x -2

Answer:

y = -3x -2

Powell believe that the inflation rate will be  4.46% over the next year .

In the question ,

it is given that

total return offered by the investment((nominal rate) = 17% = 0.17

return according to Powell Arms(real rate) = 12% = 0.12

let the inflation rate be x.

The inflation rate over the next year can be calculated using the formula .

(1+Real rate ) = (1+nominal rate )/ (1+ inflation rate )

Substituting the values , we get

(1+0.12) = (1+0.17)/(1+x)

1.12 = 1.17/(1+x)

1+x = 1.17/1.12

1 + x = 1.0446

x = 1.0466-1

x = 0.0446
