What is a quadratic function?

A polynomial of degree two in one or more variables is known as a quadratic polynomial in mathematics.

A quadratic function is a polynomial function that a quadratic polynomial defines.

The graph of a quadratic function resembles a parabola.

A polynomial equation with a maximum degree of two is referred to as a quadratic equation. Where a 0, the equation is given by ax² + bx + c = 0.

A quadratic function has the vertex form f(x) = a(x - h)2 + k, where a, h, and k are constants.

So, we have the points:
(-2, 0)

Now, insert the values in the form: f(x) = a(x – h)2 + k

0.4x+2.9=1.5 solve for x

Answers

Answer:

x= -3.5

Step-by-step explanation:

0.4x+2.9= 1.5

-2.9. -2.9

(0.4/0.4)x= -1.4/0.4

x= -3.5

By solving the given equation 0.4x + 2.9 = 1.5, the value of x is -3.5

In the given equation, we have one variable of 'x' with a constant value of 0.4 and two non-variable values of 2.9 and 1.5.

To solve the given equation, we have to transfer the non-variable values to either the L.H.S (Left Hand Side) or R.H.S (Right Hand Side) of the equation. After transferring the non-variable values, we will solve it by dividing it by the constant value of the given variable as shown below:

0.4x + 2.9 = 1.5

0.4x = 1.5 - 2.9

0.4x = -1.4

     x = [tex]\frac{-1.4}{0.4}[/tex]

A chemist wishes to make a 10% acid solution. she has a 4% acid solution and a solution that is 28% acid. how many liters of each should she use if she needs 5 liters of the 10% solution?

Answers

The chemist should use 3.75 liters of the 4% acid solution and 1.25 liters of the 28% acid solution to make 5 liters of a 10% acid solution.

Let's denote the volume of the 4% acid solution as x and the volume of the 28% acid solution as y, both in liters.

To make a 10% acid solution, we need to mix the two solutions in such a way that the resulting mixture has a total volume of 5 liters, and the concentration of acid in the mixture is 10%.

Since we want 5 liters of the final mixture, we can write the following equation based on the conservation of volume:

x + y = 5

The total amount of acid in the final mixture should be 10% of the total volume of the mixture, so we can write the following equation:

0.04x + 0.28y = 0.1(5)

On simplifying:

0.04x + 0.28y = 0.5

From the first equation:

y = 5 - x

Substituting into second equation:

0.04x + 0.28(5 - x) = 0.5

Simplifying and solving for x:

0.04x + 1.4 - 0.28x = 0.5

-0.24x = -0.9

x = 3.75

Using first equation,

x + y = 5

3.75 + y = 5

y = 1.25

Therefore, she needs to use 3.75 liters of the 4% acid solution and 1.25 liters of the 28% acid solution to make 5 liters of a 10% acid solution.

Subtract 7 from both sides (bc you’re doing the opposite of +7) So 7z +7-7 cancels out so you just have 7z. 7z = -2z -4 -7, so 7z = -2z -11

Add 2z to both sides (bc your doing the opposite again) to get 9z = -11

Divide both sides by the number of the of the term with both a number and variable, in this case 9z, the number is 9. So 9z/9= -11/9 so simplified, z= -11/9

if the inverse demand function for toasters is p=100-20 what is the consumer surplus if price is $35? The consumer surplus is $ (round your answer to two decimal places)

Answers

Given the inverse demand function p = 100 - 20q for toasters and a price of $35, we can find the consumer surplus.

First, we'll find the quantity demanded at the given price:

35 = 100 - 20q
20q = 100 - 35
q = (100 - 35) / 20
q = 65 / 20
q = 3.25

Now, to find the consumer surplus, we'll use the formula:

Consumer Surplus = (1/2) × Base × Height

The base represents the quantity (q = 3.25) and the height is the difference between the maximum willingness to pay (p = 100) and the actual price (p = 35).

Consumer Surplus = (1/2) × 3.25 × (100 - 35)
Consumer Surplus = 0.5 × 3.25 × 65
Consumer Surplus = 105.625

So, the consumer surplus is $105.63 when rounded to two decimal places.

Therefore, the answers are CA and diameter.

How do we calculate?

we have that in the question, a circle with center 'O' is passing through three A, B and C, where ∠B is a right angle.

In the circumscribed circle, we have the converse of the Thales' theorem, which states that -

if A, B, and C are distinct points on a circle where angle ∠ABC is a right-angle, then the line AC will be a diameter of the circle.

The given information is drawn in the attached figure.

Applying the converse of Thales' Theorem, we have AC will be a diameter of the circle.

As the longest side (hypotenuse) of a right-angled triangle is the opposite side of the right-angle, CA is the longest side of ABC.

The longest side of the triangle equals the diameter of the circle because CA is likewise a diameter of the circle.

Thus, the center will lie on the line segment CA and the longest side of the triangle is equal to the diameter of the circle.

let's first solve the given inequality $x^2 - 15 < 2x$. We can rewrite this inequality by moving all terms to one side:

$x^2 - 2x - 15 < 0$

Now, we want to factor the quadratic:

$(x - 5)(x + 3) < 0$

From this factored form, we can see that the quadratic changes sign at x = -3 and x = 5. This means the inequality holds between these values:

-3 < x < 5

Now, we want to find the smallest and largest integers within this interval. Since "integer" refers to whole numbers (both positive and negative), we can identify $a$ and $b$ as follows:

$a = -2$ (the smallest integer greater than -3)
$b = 4$ (the largest integer less than 5)

Using Pythagoras' theorem, we can write:

w^2 + 77^2 = 85^2

Simplifying this equation gives:

w^2 = 85^2 - 77^2

w^2 = 576

Taking the square root of both sides gives:

w = sqrt(576)

w = 24

Therefore, the width of the field is 24 meters 1.

I hope this helps!

There are 31 students in a class. Each student was asked how many pets he has at home. The table below summarizes the data.
Based on the data, estimate the probability that a randomly selected student from this class has four or more pets at home. Round your answer to the nearest two decimal places.

Answers

The probability that a randomly selected student from this class has four or more pets at home is 4/31 ≈ 0.13 when rounded to the nearest two decimal places.

Explain probability

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, with 0 indicating no chance and 1 indicating certainty. Probability is calculated by dividing the number of desired outcomes by the total number of possible outcomes. It is used in many fields, including mathematics, statistics, science, and engineering.

According to the given information

Based on the data provided, there are a total of 4 students who have four or more pets at home

(0 with 4 pets + 1 with 5 pets + 2 with 6 pets + 1 with 7 pets).

Since there are a total of 31 students in the class, the probability that a randomly selected student from this class has four or more pets at home is 4/31 ≈ 0.13 when rounded to the nearest two decimal places.

Frahan travels from Town A to Town B at an average speed of 4 Km/h and from Town B to Town A at an average
speed of 3 Km/h. He takes 25 minutes to complete the entire journey.
(a) Convert 25 minutes into hours.
(b) Find his total distance travelled.

Answers

to convert 25min into hours we divide 25 by 60 so the answer would be 0.416 hours

the formula to find the distance is we multiply speed and time so

distance=4km/p X 0.416 hours =1.664

so now we have the first answer

now we do the same thing for the other part of the question

distance= timeXspeed

distance=0.416X3=1.248

then we add to find total distance

1.248+1.644=2.912

2.912 is the total distance

a randomly selected sample of 100 students was drawn from a population with an average grade point average (gpa) of 3.2 and a standard deviation of 0.2. the standard deviation of the sampling distribution of the sample mean is

Answers

The standard deviation of the sampling distribution of the sample mean is 0.02.

The standard deviation of the sampling distribution of the sample mean can be calculated using the formula:

σ/√n

Where σ is the population standard deviation and n is the sample size.

In this case, the population standard deviation (σ) is 0.2 and the sample size (n) is 100. Substituting these values in the formula gives:

0.2/√100

Simplifying, we get:

0.2/10 = 0.02

This means that if we were to take multiple random samples of size 100 from the population, the mean of each sample would vary around the population mean of 3.2, with a standard deviation of 0.02.

This is because the standard deviation of the sampling distribution represents the amount of variation in sample means around the population mean.

how many times as many robberies were there actually in year 5 compared to year 3? round your answer to 2 decimal places.

Answers

The answer to 2 decimal places, we only need to keep two numbers after the decimal point. In this case, there are no numbers after the decimal point, so the answer is simply 5.00.

To find the answer, we need to know the number of robberies in year 3 and year 5. Let's say there were 100 robberies in year 3 and 500 robberies in year 5.

To compare the two numbers, we can divide the number of robberies in year 5 by the number of robberies in year 3:

500/100 = 5

This means that there were 5 times as many robberies in year 5 compared to year 3.

Answer:

Step-by-step explanation:

The total number are 12+14+16=42

and the movie was not a comedy are adventure and drama which stands for 12 and 16. The total of them is 28.

So the movie was not a comedy is 28/42 = 2/3

Answer:

D.

Step-by-step explanation:

If you want to know the chance that the movie you watched was not a comedy, you have to do some math. Don't worry, it's not hard. You just need to use this formula:

P(not funny) = 1 - P(funny)

This means that the probability of not laughing is one minus the probability of laughing. How do we find the probability of laughing? Well, we look at how many movies are comedies and how many movies are total. In this case, there are 14 comedies and 42 movies in total. So we divide 14 by 42 and get:

P(funny) = 14 / 42

This fraction can be simplified to:

P(funny) = 1 / 3

Now we plug this into the formula and get:

P(not funny) = 1 - (1 / 3)

This can be simplified to:

P(not funny) = 2 / 3

So there you have it. The probability that the movie was not a comedy is 2 / 3. That means you have a higher chance of watching a boring movie than a funny one. Maybe you should pick a different genre next time.

The right answer is d. 2/3.

Magda, David, and Rashida have been friends since the sixth grade. One of their favorite activities is to go to the mall and look around in the stores. Sometimes they make purchases and sometimes they are just window-shopping. There are lots of young people who do this, and it is fun to see people and hang out. Recently, a number of stores at the mall have experienced an increase in shoplifting and vandalism. As a result, the stores have made a policy that no one under 16 years of age can enter without a parent or guardian. The new rules also state that if you are between the ages of 16 and 18 you cannot enter the store in groups larger than two. Other teens have to wait outside until each pair leaves. Store owners have threatened to call the police if the young people give them any trouble about the new policies. This policy makes Magda, David, and Rashida angry. They believe it is unfair. After all, they are paying customers and spend money in these stores. Why is the rule directed only at young people? They do not want to get into trouble with the police, but they do not understand why they have to be treated as troublemakers when they have not done anything wrong.
