The horizontal asymptote is y = -2

What do you mean by asymptote?

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity. The curves visit these asymptotes but never overtake them.

The horizontal asymptote is an equation of the form y = k, for some constant k, is a straight line parallel to x-axis.

Horizontal asymptotes are found for rational functions of polynomials when x becomes extremely large, or, as x → ∞.

The function given is, f(x) = (-2x²+3x+5)/(x²+1)

Answer:

(a) 8800000

(b) Barcelona had the least population in 2018

(c) The difference in population is 2.9 x [tex]10^{7}[/tex]

Step-by-step explanation:

(a) Since '10' is raised to a positive power, the decimal will be moving in the forward direction, In other words, it will move towards the right. Therefore, the decimal will be moving 6 places forward. After which, the empty slot(s) will be occupied by zeros

8.8 x [tex]10^{6}[/tex] = 8800000

(b) First notice that three out of the five cities have population expressed in [tex]10^{6}[/tex] (where 6 is the least power). Then notice that out of those three cities, the smallest number corresponds to Barcelona (i.e. 5.5).

Therefore, Barcelona had the least population in 2018

(c) Population of:

Tokyo: 3.7 x [tex]10^{7}[/tex]

Ahmedabad: 7.7 x [tex]10^{6}[/tex]

First, make sure the two numbers are expressed in the same standard form (meaning 10 is raised to the same power in both cases):

Tokyo: 3.7 x [tex]10^{7}[/tex] = 3.7 x 10 x [tex]10^{6}[/tex]  =37 x [tex]10^{6}[/tex]

Ahmedabad: 7.7 x [tex]10^{6}[/tex]

Next step:

37 x [tex]10^{6}[/tex] - 7.7 x [tex]10^{6}[/tex]

= (37 - 7.7) x [tex]10^{6}[/tex]

= 29.3 x [tex]10^{6}[/tex]  

= 29 x [tex]10^{6}[/tex] (Corrected to 3 significant figures)

= 2.9 x 10 x [tex]10^{6}[/tex]

What is the combination?

A combination is a method of selecting items from a collection where the order of selection is irrelevant.

The combination is defined as "an arrangement of objects in which the order in which the objects are chosen is unimportant." The combination means "selection of things," where the order is irrelevant.

The formula of combination is nCr = n!/[r!(n-r)!]

Where n is the total number of objects and r is the number of objects those are selected.

Case 1: one-topping pizzas

The number of different toppings is 6.

Selecting one topping is ₆C₁  = 6!/[1!5!] = 6

Case 2: two-topping pizzas

The number of different toppings is 6.

Selecting two topping is ₆C₂  = 6!/[2!4!] = 15

Using probability the value of p + q = -0.4

Probability is the likelihood of an event.

Given the Venn diagram and that the probabilities are independent events.

The probability of A or B is given by

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Also, the probability of A and B is given by P(A ∩ B) = P(A)P(B)

So, we have that

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

P(A ∪ B) = P(A) + P(B) - P(A)P(B)

From the Venn diagram, we have that

P(A) = p + q

P(B) = q + 0.6

P(A ∩ B) = q

P(A ∪ B) = 0.2

So, substituting these into the equation, we have that

P(A ∪ B) = P(A) + P(B) - P(A)P(B)

0.2 = p + q + q + 0.6 -  q

0.2 = p + 2q - q + 0.6

The number of possible values for m is 3.

An integer a is its own inverse mod m if a * a^(-1) = 1 (mod m)

For the first condition, 9 is its own inverse mod m, 99^(-1) = 1 (mod m)

so 99^(-1) = 1 + km for some integer k.

so 9*9^(-1) - 1 = km

so 8 = km

so m must be a divisor of 8.

For the second condition, 3 is not its own inverse mod m, 33^(-1) ≠ 1 (mod m)

so 33^(-1) = 1 + km for some integer k, k ≠ 0

so 3(3^(-1) - 1) = km

so 3(3^(-1) - 1) = km

so 3(1 - 3^(-1)) = km

so 3(1 - 9^(-1)) = km

so 3(8 - 9^(-1)) = km

so 38 - 39^(-1) = km

so 24 - 39^(-1) = km

so 24 - 27^(-1) = km

so 24 - 27^(-1) = km

so -327^(-1) = km

so -33^(-1) = km

so -33^(-1) = km

so 33^(-1) - 1 = km

so 33^(-1) = 1 + km

so 3*3^(-1) ≠ 1 (mod m)

Buffalo Mild Wings offers the lowest price per wing.

Lowest Price:

Demands for the lowest possible price are more commonly seen in markets with limited liquidity or low trading volume, or from traders in companies with very small market caps. This is because investors trading illiquid securities are less likely to fill buy and sell orders. Markets for less traded securities are more limited and other parties can charge prices that may not be ideal for investors. For example, investors who want to trade currency options in foreign currencies (i.e. currencies other than dollars, euros, pounds or yen) often use the lowest possible price.

According to the Question:

Given:

Buffalo Bills has 8 wings for $7.

Buffalo Mild Wings has 12 wings for $10.

Wingers has 20 wings for $17.

To Find:

Which restaurant offers the lowest price per wing?

Solution:

Find the price per wing in Buffalo Bills:

8 wings = $7

1 wing = 7 ÷ 8

1 wing = $0.875

Find the price per wing in Buffalo Mild Wings:

12 wings = $10

1 wing = 10 ÷ 12

1 wing = $0.833

Find the price per wing in Wingers:

20 wings = $17

1 wing = 17 ÷ 20

1 wing = $0.85

Now,

Comparing  $0.875 , $0.833 and $0.85:

The greatest number of police officers needed is 28.

In a scenario where there are n straight lines in a city, and none of the lines are parallel to each other, the maximum number of police officers needed at the intersections can be determined by using the summation formula. The summation formula for the series of numbers from 1 to n-1 is (n-1) * n / 2.

Thus, if there are 8 straight lines in a city, the maximum number of police officers needed at the intersections is (8-1) * 8 / 2 = 28. This is because there will be 8-1 = 7 intersection points in total, and at each intersection point, one police officer is needed.

It's important to note that this is the maximum number of officers needed and it assumes that all lines are intersecting at different points. In case of any parallel lines this number would be less.

Value is an important concept in economics and business that refers to the worth of a product, service, or asset. It is a measure of the relative worth of something compared to other similar items. Value can be determined by a variety of factors, such as the quality, condition, and availability of an item. It can also be based on a customer's perception or opinion of a product or service. Values can vary from person to person, and can even change over time. Ultimately, value is a subjective concept that is determined by the beliefs and preferences of individuals.

The minimum amount of time (in seconds) it takes for a vehicle to pass through the zone without exceeding the posted speed limit of miles per hour is 4.8708 seconds.

We can solve this problem easily by using the Pythagorean Theorem. This is because the distances from the cop car to the road form two legs of a right triangle. This makes the total length of this zone the hypotenuse of this triangle and thus, this problem can be solved using the Pythagoras theorem.

= (150)^2 + (200)^2 = h^2

= 62500 = h^2

= h = 250

Our distance is in feet, but our speed is in miles per hour. Let's convert this distance into miles as well.

= 250 feet × 1 mile/5280 feet = 0.04735 miles

Then, when we use the formula  d = rt

= 0.04735 = 35t

= 0.04735/ 35 ≈ 0.001353

Since our speed was in miles per hour, this time is also in hours. We need to convert this to seconds before we can state our final answer.

Generally, The vertex form of a parabola that opens downward is

f(x) = a(x-h)^2 + k,

where (h,k) is the vertex of the parabola.

We know that the vertex of the parabola is at (1.5, 10) so we can use that to find the value of a and h. So,

f(x) = a(x-1.5)^2 + 10

Given that the parabola goes through (- 2, - 2) and (5, - 2), we can substitute these points into the equation to find a and k.

Substituting (-2, -2) into the equation:

-2 = a((-2) - 1.5)^2 + 10

Substituting (5, - 2) into the equation:

-2 = a(5 - 1.5)^2 + 10

Solving these two equations will give you a = -1/2 and k = -8

So the equation is f(x) = -1/2(x-1.5)^2 - 8

The graph of a parabola is increasing on the interval where the derivative is greater than 0.

To find the derivative, we use the power rule and the chain rule:

x - 2 = 4 - x ==> x should be 3 in this case. (a = 3)

If x or a is equal to 3, we can use this value to find y (or b).

Solving for the first equation:

x - y = 2 ==> (3 - y = 2)

y is equal to 1.
