i think question is about implicit differentiation

Answers

The x-coordinates of the points on the curve where the tangent line is horizontal will be option A.

How to explain the coordinate

(x² + y²)² = 4(x² – y²)

x⁴ + 2x²y² + y⁴ = 4x² - 4y²

y⁴ + 2x^2y² + 4y² - 4x² = 0

Now we can use implicit differentiation to find the derivative of y with respect to x:

4y³(dy/dx) + 4xy² + 4y(dy/dx)x² + 8y(dy/dx) - 8x = 0

Simplifying this expression, we get:

4y³(dy/dx) + 4xy² + 4xy²(dy/dx) + 8y(dy/dx) - 8x = 0

(dy/dx)(4y³ + 4x²y²) + 8y(dy/dx) = 8x - 4xy²

(dy/dx)(4y³ + 4x^2y² + 8y) = 4x(2-y²)

(dy/dx) = 4x(2-y²)/(4y³ + 4x²y² + 8y)

Based on the information, x-coordinates of the points on the curve where the tangent line is horizontal will be option A.

A group of marketing researchers for a popular cell phone manufacturer collected the following information about young adults (aged 18–25): 1% use a cell phone that is 3 years or older, 2% use a cell phone that is 2–3 years old, 20% use a cell phone that is 1–2 years old, and 77% use a cell phone that is less than 1 year old. Suppose a young adult was selected at random. Let X equal the age of a randomly selected person’s cell phone. Which of the following is the probability distribution for the age of that person’s cell phone?

Answers

according to the question 77% population use a cell phone that is less than 1 year old.

What is probability?

Probability theory, a subfield of mathematics, quantifies the likelihood that an event is going to happen or that a statement is true. The probability for an event is a number between 0 and 1, where 0 roughly denotes how probable the event is to occur and 1 denotes certainty. A probability is a numerical representation of the likelihood that a certain event will occur. In addition to numbers from 0 to 1, probability values can also be stated as percentages between 0% and 100%. the fraction of an entire set of equally likely possibilities that result in a certain occurrence out of all possible outcomes, expressed as a ratio.

given,

The probability distribution for the age of a randomly selected young adult's cell phone can be represented using a probability mass function (PMF) as follows:

P(X = 3) = 0.01 (1% use a cell phone that is 3 years or older)

P(2 ≤ X ≤ 3) = 0.02 (2% use a cell phone that is 2-3 years old)

P(1 ≤ X ≤ 2) = 0.20 (20% use a cell phone that is 1-2 years old)

P(X < 1) = 0.77 (77% use a cell phone that is less than 1 year old)

Note that the values of the PMF correspond to the probabilities of the different age categories for the cell phones of young adults. The PMF satisfies the two main properties of a probability distribution: 1) the probabilities are non-negative, and 2) the sum of the probabilities is equal to 1.

Verify directly that F is an antiderivative of f.​

Answers

F(x) is an antiderivative of f(x) because F'(x) = f(x)

What is an antiderivative?

An anti-derivative is the integral of a function

To verify that F is an antiderivative of f where

F(x) = √(3x² - 4) and f(x) = 3x/√(3x² - 4)

This means that F(x) = ∫f(x)

This implies that F'(x) = f(x)

So, we verify as follows

F(x) = √(3x² - 4)

Taking the derivative with respect to x, we have that

dF(x)/dx = d√(3x² - 4)/dx

Let u = 3x² - 4

So, dF(x)/dx = d√u/dx

= d√u/du × du/dx

= 1/(2√u) × du/dx

Now,du/dx = d(3x² - 4)/dx

= 6x

So,

dF(x)/dx  = 1/(2√u) × du/dx

= 1/(2√(3x² - 4)) × 6x

= 1/(√(3x² - 4)) × 3x

= 3x/(√(3x² - 4))

= f(x)

So, F(x) is an antiderivative of f(x) because F'(x) = f(x)

The lengths of two sides of a triangle are shown.
Side 1: 3x² - 4x-1
Side 2: 4x-x² +5
The perimeter of the triangle is 5x³ - 2x² + 3x - 8.
Part A: What is the total length of the two sides, 1 and 2, of the triangle? Show your work.
Part B: What is the length of the third side of the triangle? Show your work.
Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer.

Answers

Answer:

Part A:

To find the total length of the two sides of the triangle, we need to add Side 1 and Side 2:

Side 1: 3x² - 4x - 1

Side 2: 4x - x² + 5

Total length: (3x² - 4x - 1) + (4x - x² + 5)

Simplifying and combining like terms, we get:

Total length: -x² + 7x + 4

Therefore, the total length of the two sides of the triangle is -x² + 7x + 4.

Part B:

To find the length of the third side of the triangle, we need to subtract the sum of Side 1 and Side 2 from the perimeter of the triangle:

Length of Side 3 = Perimeter - (Side 1 + Side 2)

Length of Side 3 = (5x³ - 2x² + 3x - 8) - (3x² - 4x - 1 + 4x - x² + 5)

Simplifying and combining like terms, we get:

Length of Side 3 = 2x³ - 2x² + 7x - 12

Therefore, the length of the third side of the triangle is 2x³ - 2x² + 7x - 12.

Part C:

The answers for Part A and Part B show that the polynomials are closed under addition and subtraction. The sum of Side 1 and Side 2 is a polynomial (-x² + 7x + 4), and the difference between the perimeter of the triangle and the sum of Side 1 and Side 2 is also a polynomial (2x³ - 2x² + 7x - 12). In both cases, the result is a polynomial, which means that the set of polynomials is closed under addition and subtraction.

Answers

The true expression about the account is D.) It is the sum of the initial amount and the additional amount after d days.

What does the expression 10+0.5(d−1) represent in Owen's savings account?

The answer is D because it represents the sum of the initial amount and the additional amount after d days. The initial amount is $10 and Owen adds $0.50 to the account each day for a number of days, represented by d.

By subtracting 1 from d, the expression ensures that on the first day (when d=1), only the initial $10 is counted. On each subsequent day, the additional amount of $0.50 is added to the total. Therefore, the expression 10+0.5(d−1) gives the amount of money in Owen's account after d days.

A deli wraps its cylindrical containers of hot food items with plastic wrap. The containers have a diameter of 5.5 inches and a height of 3 inches. What is the minimum amount of plastic wrap needed to completely wrap 8 containers? Round your answer to the nearest tenth and approximate using π = 3.14.

Answers

To calculate the minimum amount of plastic wrap needed to completely wrap 8 cylindrical containers, we need to calculate the total surface area of the 8 containers.

The formula for the surface area of a cylinder is:

A = 2πr^2 + 2πrh

where r is the radius of the base of the cylinder (which is half the diameter), h is the height of the cylinder, and π is approximately equal to 3.14.

To find the total surface area of 8 containers, we can first calculate the surface area of one container and then multiply by 8:

r = 5.5 / 2 = 2.75 inches
h = 3 inches

A = 2π(2.75)^2 + 2π(2.75)(3) = 81.85 square inches

The total surface area of 8 containers is:

8A = 8(81.85) = 654.8 square inches

Therefore, the minimum amount of plastic wrap needed to completely wrap 8 cylindrical containers is approximately 654.8 square inches, rounded to the nearest tenth.

Describe Probability?

A triangle is a polygon with three straight sides and three angles. It is one of the most fundamental shapes in geometry and is used extensively in mathematics, science, engineering, and art. The sum of the interior angles of a triangle is always 180 degrees, and the length of the sides and the size of the angles determine the shape of the triangle.

Triangles can be classified according to the length of their sides and the size of their angles. A scalene triangle has three unequal sides and three unequal angles. An isosceles triangle has two equal sides and two equal angles. A equilateral triangle has three equal sides and three equal angles, each measuring 60 degrees. Triangles can also be classified based on the size of their angles: an acute triangle has three acute angles (less than 90 degrees), a right triangle has one right angle (90 degrees), and an obtuse triangle has one obtuse angle (greater than 90 degrees).

Triangles have many important properties and applications in geometry. For example, the Pythagorean theorem is a fundamental relationship between the sides of a right triangle, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The area of a triangle can be calculated using the formula 1/2 x base x height, and this formula can be used to solve many practical problems involving triangles.

The random variable P can take on four possible values, depending on how many heads are obtained:

P = 0 if both coins show tails.

P = 1 if exactly one of the coins shows heads.

P = 2 if both coins show heads.

Therefore, the possible values of the random variable P are 0, 1, or 2.

Give your answers correct to 2 decimal places

Answers

The two solutions to the simultaneous equations are; y1 = -0.87  and y2 = 2.87. x1 = 2.87, x2 =  -0.87

How do you solve the simultaneous equations?

To solve these simultaneous equations, we can use the method of substitution. We can rearrange the second equation to isolate one of the variables, for example, y:

y = 2 - x

Now, substitute this expression for y into the first equation:

x^2 + (2 - x)^2 = 9

Expand the equation:

x^2 + (4 - 4x + x^2) = 9

Combine like terms:

2x^2 - 4x + 4 = 9

Move all terms to one side to set the equation to equal zero:

2x^2 - 4x - 5 = 0

Now, we can solve this quadratic equation using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In our equation, a = 2, b = -4, and c = -5:

x = (4 ± √((-4)^2 - 4(2)(-5))) / (2 x 2)

x = (4 ± √(16 + 40)) / 4

x = (4 ± √56) / 4

The two possible values for x are:

x1 ≈ (4 + 7.48) / 4 = 2.87

x2 ≈ (4 - 7.48) / 4 = -0.87

Now, we'll find the corresponding y values using the equation y = 2 - x:

For x1 ≈ 2.87:

y1 ≈ 2 - 2.87 ≈ -0.87

For x2 ≈ -0.87:

y2 ≈ 2 - (-0.87) ≈ 2.87

So, the two solutions to the simultaneous equations are approximately (2.87, -0.87) and (-0.87, 2.87), both correct to 2 decimal places.

                         Sometimes the following is referred to as a "direct equation of two variables," where y and x are the variables. Direct equations are those in which all of the variables are powers of one. In one example with just one variable, layoff b = 0, where a and b are real numbers and x is the variable, is used.

It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...

The circumference of the smaller circle is 25% of the circumference of the larger circle. Find the circumference of the larger circle. Round your answer to the nearest tenth

Answers

The circumference of the larger circle is approximately 9.4 units.

What is circumference?

The circumference is the distance around the edge or boundary of a closed two-dimensional shape, such as a circle or an ellipse.

According to question:

Let C be the circumference of the larger circle. Then the circumference of the smaller circle is 0.25C, according to the given information.

We know that the circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Therefore, we can write:

C = 2πr for the larger circle

0.25C = 2πr for the smaller circle

Dividing the second equation by 0.25, we get:

C = 8πr for the smaller circle

Now we can equate the two expressions for C and solve for r:

2πr = 8πr

6πr = C

r = C/(6π)

Finally, we can substitute this value of r into the expression for C in terms of r for the larger circle:

C = 2πr = 2π(C/(6π)) = (1/3)Cπ

Solving for C, we get:

C = (3/π)C

C = 3π ≈ 9.4 (rounded to the nearest tenth)

The ratio of whites to blacks is 20 to 3 ( or 20/3) in United States in 1990.

From a survey of the population of the United States, a circle graph (or, pie chart) was created on the information,

Population of the United States in 1990 :

White consists of 80%

American Indian, Eskimo, and Aleut consists of 1%

Black consists of 12%

Asian and Pacific Islander consists of 3%

Other Races consists of 4%

Let say the total population of the United States in 1990 was x.

By applying the formula of percentage to numbers we get,

The number of people who were white in 1990 in United States = 80% of x

= [tex][\frac{80}{100} ]x[/tex] = [tex]\frac{4}{5} x[/tex]

The number of people who were black in 1990 in United States = 12% of x

= [tex][\frac{12}{100} ]x[/tex] = [tex]\frac{3}{25} x[/tex]

Thus, we can calculate ratio as,

Ratio of whites to blacks = [tex]\frac{\frac{4}{5} x}{\frac{3}{25} x}[/tex] = 20/3

Which function is undefined for x = 0?
O y=³√√x-2
y = √√√x-2
Oy=³√√x+2
O
y=√x+2
O

Answers

The function y = √x+2 is undefined for any value of x that makes the expression inside the square root negative, which in this case is x ≤ -2.

What is an inequality equation?

An inequality equation is a mathematical statement that compares two expressions using an inequality symbol such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

The function that is undefined for x = 0 is y = √x+2.

When x = 0, we have:

y = √0+2

y = √2

Since there is no real number whose square is negative, the square root of a negative number is undefined in real numbers.

Therefore, the function y = √x+2 is undefined for any value of x that makes the expression inside the square root negative, which in this case is x ≤ -2.
