The equilibrium price and quantity if the government imposes a fixed tax of $36 on each good is $26 and  the corresponding value of the government tax revenue is $648

To find the equilibrium price and quantity, we need to set Qs = Qd and solve for the price.

Qs = Qd

=> p = -3Qd + 80 = Qs + 8

=> -3Qd + 80 = Qd + 8 (substituting Qs = Qd)

=> 4Qd = 72

=> Qd = 18

=> Qs = 18

Therefore, the equilibrium price is:

p = Qs + 8 = 18 + 8 = 26

Now, if the government imposes a fixed tax of $36 on each good, the new supply function becomes:

p = Qs + 8 - 36

=> Qs = p - 28

And the demand function remains the same:

p = -3Qd + 80

Setting Qs = Qd and substituting Qs and Qd in terms of p, we get:

p - 28 = -3Qd + 80

=> -3Qd = p - 52

=> Qd = (52 - p) / 3

The government tax revenue is the product of the tax and the quantity sold, which is:

Tax revenue = tax per unit × quantity sold

=> Tax revenue = 36 ×Qs

Substituting Qs = 18, we get:

Tax revenue = 36 × 18 = $648

If an item has a listed price of $65 and the sales tax rate is 5%, the sales tax will be $3.25 and the total cost will be $68.25.

If the item has a listed price of $65, the sales tax rate is 5%, we can first calculate the amount of sales tax as follows:

Sales Tax = Listed Price x Sales Tax Rate

Sales Tax = $65 x 0.05

Sales Tax = $3.25

So the sales tax on the item is $3.25.

To calculate the total cost, we simply add the sales tax to the listed price:

Total Cost = Listed Price + Sales Tax

Total Cost = $65 + $3.25

Total Cost = $68.25

So the total cost of the item with sales tax is $68.25.

Logan will pay $18.02 more if he buys the wooden stacking toy instead of the plastic stacking toy.

The cost of the plastic stacking toy is 1/3 the cost of the wooden stacking toy:

Cost of plastic toy = (1/3) x $25.50 = $8.50

If Logan buys the wooden toy, he will pay:

Cost of wooden toy = $25.50

To find the amount of sales tax on either toy, we can multiply the cost of the toy by the tax rate of 6%:

Sales tax = 6% x cost of toy

Sales tax on the wooden toy = 6% x $25.50 = $1.53

Sales tax on the plastic toy = 6% x $8.50 = $0.51

If Logan buys the wooden toy, he will pay an extra:

Total cost difference = Cost of wooden toy - Cost of plastic toy + Sales tax on wooden toy - Sales tax on plastic toy

Total cost difference = ($25.50 - $8.50) + ($1.53 - $0.51)

Total cost difference = $17 + $1.02

A formula relating y to t is y = 6.55[tex]e^{k(22)}[/tex]ln(26/6.5)t)

Let's consider a sample culture of bacteria with an initial area of 6.5. We observe that the population of bacteria doubles in size every 22 minutes. We want to find a formula that relates the area of the sample culture, denoted as y, to the time passed, denoted as t.

Let's call this proportionality constant k. We can then write the differential equation that describes the growth of the population as:

dy/dt = ky

where dy/dt is the rate of change of the area with respect to time.

We can solve this differential equation by separation of variables. We first separate the variables and then integrate both sides:

dy/y = k dt

∫(dy/y) = ∫k dt

ln|y| = kt + C

where C is a constant of integration. To solve for C, we use the initial condition that the area of the sample culture is 6.5 when t = 0. This gives:

ln|6.5| = k(0) + C

C = ln|6.5|

Substituting this value of C back into the solution, we get:

ln|y| = kt + ln|6.5|

ln|y/6.5| = kt

Finally, we can solve for y to get the formula we were looking for:

y = 6.5[tex]e^{kt}[/tex]

where k is the proportionality constant that depends on the doubling time of the bacteria. We can use the fact that the population doubles in size every 22 minutes to find k. If the population doubles, then the area of the population quadruples. This means that after 22 minutes, the area is 6.5 x 4 = 26. We can use this to find k:

26 = 6.5[tex]e^{k(22)}[/tex]

[tex]e^{k(22)}[/tex] = 26/6.5

k(22) = ln(26/6.5)

k = (1/22)ln(26/6.5)

Substituting this value of k back into the formula we derived earlier, we get the exact expression relating y to t:

y = 6.55[tex]e^{k(22)}[/tex]ln(26/6.5)t)

Answer: e, an=6n-7.

Step-by-step explanation: Any pair of consecutive terms can be used to determine the arithmetic sequence's common difference (d), which can then be used in conjunction with the given term to determine the nth term using the following formula:

an = a1 + (n - 1) d.

Let's use the pair a11=53 and a10=47 to find d:

d = a11 - a10 = 53 - 47 = 6

Now we can use the formula to find any term of the sequence. Let's use the given value of a13=65 to find a13:

a13 = a1 + (13 - 1)d

65 = a1 + 12(6)

65 = a1 + 72

a1 = -7

Therefore, the formula that can be used to find the nth term of the arithmetic sequence is:

an = -7 + (n - 1)6

Simplifying this expression, we get:

an = 6n - 7.

Answer:

Step-by-step explanation:

First, we need to determine the slope of the line we want to find since it is perpendicular to the given line. The slope of a line perpendicular to another line is the negative reciprocal of the slope of the given line.

The given line has a slope of -1/3, so the slope of the line we want to find is 3 (the negative reciprocal of -1/3).

Now we can use the point-slope form of the equation of a line to find the equation of the line passing through (1,-10) with a slope of 3:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is the point. Substituting the values we have:

y - (-10) = 3(x - 1)

Simplifying:

y + 10 = 3x - 3

Subtracting 10 from both sides:

y = 3x - 13

Therefore, the equation of the line perpendicular to y=-1/3x+5 and passing through the point (1,-10) is y = 3x - 13.

The measure of exterior angle 1 is 120 degrees. (option a)

In this case, we are given two interior angles of the polygon, which are 60 degrees and 25 degrees. The sum of the measures of the interior angles of a polygon with n sides is given by the formula (n-2) x 180 degrees. Therefore, for this polygon, the sum of its interior angles can be calculated as

=> (n-2) x 180 = (3-2) x 180 = 180 degrees.

Next, we can use the fact that the sum of an exterior angle and its adjacent interior angle is always 180 degrees. Therefore, we can calculate the measure of the exterior angle 1 as follows:

Exterior angle 1 + Interior angle 1 = 180 degrees

Exterior angle 1 + 60 degrees = 180 degrees (since we know that Interior angle 1 is 60 degrees)

Exterior angle 1 = 180 degrees - 60 degrees

Exterior angle 1 = 120 degrees

Step-by-step explanation:

First, you need to solve for x by isolating it on one side of the inequality. You can do this by adding 3 to both sides and then dividing by 2:

2x - 3 > 1

2x - 3 + 3 > 1 + 3

2x > 4

2x / 2 > 4 / 2

x > 2

Next, you need to find two numbers that are greater than 2 and plug them into the inequality to check if they make it true. You can choose any numbers that are larger than 2, but it is easier to pick from the given options. For example, let’s try A. 3/2 and B. 10/2:

A. x = 3/2

2(3/2) - 3 > 1

3 - 3 > 1

0 > 1, False

B. x = 10/2

2(10/2) - 3 > 1

10 - 3 > 1
7 > 1, True

Then, you need to repeat the same process for the remaining options until you find another number that makes the inequality true. For example, let’s try C. 1, D. 2, and E. 6.3:

C. x = 1

2(1) - 3 > 1

2 - 3 > 1

-1 > 1 False

D. x = 2

2(2) - 3 > 1

4 - 3 > 1

1 > 1, False

E. x = 6.3

2(6.3) - 3 > 1

12.6 - 3 > 1

9.6 > 1, True

Finally, you need to select the two numbers that make the inequality true from the options. The answer is B. and E. B. 10/2 and E. 6.3 are two numbers that make the inequality true.

In this problem we find two cases of composite functions that must be evaluated at given x-value. The procedure is described below:

Now we proceed to solve for each case:

Case 1: f(x) = x² + x - 4, g(x) = 3 · x + 2

(f ° g) (x) = [(3 · x + 2)² + (3 · x + 2) - 4]

(f ° g) (1) = [(3 · 1 + 2)² + (3 · 1 + 2) - 4]

(f ° g) (1) = (5² + 5 - 4)

(f ° g) (1) = 26

Case 2: f(x) = x² + x, g(x) = x² - 1

(f + g) (x) = (x² + x) + (x² - 1)

(f + g) (x) = 2 · x² + x - 1
