The degree of f(x) is 4  and the leading coefficient is Positive. There are distinct 4 real zeros and 2 relative minimum values.

The largest power of the variables in a polynomial expression is the polynomial's degree.

The leading coefficient of a polynomial, or the number that is placed before the x with the highest exponent, is the coefficient of the term with the highest degree of the polynomial in mathematics.

The locations when a polynomial equals zero overall are known as its zeros. In simple words, we can state that a polynomial's zeros are variable values at which the polynomial equals 0.

The heights and dips of a polynomial—the locations where direction changes are its extreme values. Here the heights and dips are called relative maxima and minima.  

Here we have

a "W" shaped graph opened upwards

In general, the 'W' shaped graph will have a 4th degree.

=> Degree of the given polynomial is 4

Since the graph opened upwards the leading coefficient is positive.

The number of real zeros is determined by the quantity of x-axis cutting points, as we can see that the graph cuts the x-axis 4 times

=> Number of real zeros of polynomial = 4

The heights and dips of a polynomial

The number of height in the graph is 2

=> The relative extreme values of Polynomials = 2

Therefore,

The degree of f(x) is 4  and the leading coefficient is Positive. There are distinct 4 real zeros and 2 relative minimum values.

Using the multiplication rule, the joint probability of event A and event B is computed by multiplying the conditional probability of event A given event B by the probability of event B.

Mathematically, it can be represented as P(A and B) = P(A|B) × P(B), where P(A|B) is the conditional probability of A given B, and P(B) is the probability of B.

In other words, the multiplication rule is used to compute the probability of two events occurring together, given the probability of one event occurring and the probability of the other event occurring given the first has occurred. This rule is widely used in probability and statistics to calculate the probability of complex events, especially in cases where events are not mutually exclusive.

For example, consider a scenario where we want to calculate the probability of getting two heads when flipping two coins. Using the multiplication rule, we can calculate this probability as follows: P(Two heads) = P(Head on first flip) × P(Head on second flip given the first flip was a head) = (1/2) × (1/2) = 1/4.

Answer:

C

Step-by-step explanation:

C is the only one that is an enlarged version of A.

In the first question, the statement "Using logarithmic differentiation we obtain that the derivative of the function y = x² satisfies the equation y = 4x log x + 2x" is true.

In the first question, using logarithmic differentiation on the function y = x², we differentiate both sides, apply the product rule and logarithmic differentiation, and simplify to obtain the equation y = 4x log x + 2x, which is correct.

In the second question, the statement is false. When using logarithmic differentiation on the function y = (1+x²)²(1 + sin x)²/(1-x²), the derivative is calculated correctly, but the equation given is incorrect. The correct equation after logarithmic differentiation should be y' = (4x/(1 + x²)(1 + sin x))(1-x²) - (2x(1+x²)²(1 + sin x)²)/(1-x²)².

In the third question, the product z²w is calculated correctly as 30-10%.

It is important to accurately apply logarithmic differentiation and perform the necessary calculations to determine the derivatives and products correctly.

In polar coordinates, the radial distance "r" is defined as the distance from the origin to a point in the plane. Since distance cannot be negative, we only consider the positive square root of 3 in the range for this problem. So, the correct range for "r" is 0 ≤ r ≤ √3, and negative square root of 3 is not included because it doesn't represent a valid distance in polar coordinates.

To find the volume of the given solid enclosed by the hyperboloid −x2 − y2 + z2 = 6 and the plane z = 3 using polar coordinates, we need to express the equation of the hyperboloid in terms of polar coordinates.

Substituting x = rcosθ and y = rsinθ, we get:

−r2cos2θ − r2sin2θ + z2 = 6

Simplifying, we get:

z2 = 6 - r2

Since the plane z = 3 intersects the hyperboloid, we have:

3 = √(6 - r2)

Solving for r, we get:

r = √3

Hence, the range for r is 0 ≤ r ≤ √3.

In summary, the negative square root of 3 is not included in the range of r because r represents a distance and cannot be negative. The volume of the solid can be found by integrating the function f(r,θ) = √(6 - r2) over the range 0 ≤ r ≤ √3 and 0 ≤ θ ≤ 2π using polar coordinates. The result will be in cubic units and can be obtained by evaluating the integral.

The correct option is D)  n is 30 or larger.

To apply the Central Limit Theorem (CLT) to the sampling distribution of the sample mean, the required sample size depends on the underlying population distribution.

Specifically, the CLT states that as the sample size (n) increases, the sampling distribution of the sample mean becomes approximately normal regardless of the population distribution.

However, there are some general rules of thumb that can be used to determine if the sample size is large enough to apply the CLT:

The slope of the equation is -2/3, and the y-intercept is 490.

To change the equation 2x + 3y = 1,470 to slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept, we need to solve for y.

Starting with the given equation:

2x + 3y = 1,470

First, let's isolate y by subtracting 2x from both sides of the equation:

3y = -2x + 1,470

Next, divide both sides of the equation by 3 to solve for y:

y = (-2/3)x + 490

Now we have the equation in slope-intercept form, y = (-2/3)x + 490.

From this form, we can identify the slope and y-intercept:

The slope (m) is the coefficient of x, which is -2/3.

The y-intercept (b) is the constant term, which is 490.

Therefore, the slope of the equation is -2/3, and the y-intercept is 490.

the probability that a student, answering each question at random, will answer at least 14 questions correctly is approximately 0.0000039 rounded to seven decimal places.

To calculate the probability that a student, answering each question at random, will answer at least 14 questions correctly, we can use the binomial probability formula.

The probability of answering a question correctly by random chance is 1 out of 5, which can be expressed as 1/5 or 0.2.

Let's denote:

n = number of trials (number of questions) = 20

p = probability of success (probability of answering a question correctly) = 0.2

x = number of successful outcomes (number of questions answered correctly)

We want to calculate the probability of answering at least 14 questions correctly, which means we need to find the probability of getting 14, 15, 16, 17, 18, 19, or 20 questions correct.

Using the binomial probability formula, we can calculate the probability for each case and sum them up:

P(X ≥ 14) = P(X = 14) + P(X = 15) + P(X = 16) + P(X = 17) + P(X = 18) + P(X = 19) + P(X = 20)

P(X = k) = (n choose k) * \(p^k * (1 - p)^{(n - k)\)

Using this formula for each value of k and adding them up, we find:

P(X ≥ 14) ≈ 0.0000039

Answer: The wall that Randy is painting is 20 feet long and 6 feet high. The two corners that he is not painting are triangular in shape and are each 6 feet high and 4 feet wide.

So the area of the wall that Randy is going to paint is:

20 ft * 6 ft = 120 sq ft

The area of the two corners that Randy is not painting is:

(1/2) * 4 ft * 6 ft = 12 sq ft

Therefore, the total area that Randy needs to paint is:

120 sq ft - 12 sq ft = 108 sq ft

One gallon of paint will cover 100 square feet.

So Randy will need to purchase 108 sq ft / 100 sq ft/gallon = 1.08 gallons of paint.

Randy will have to purchase 1.08 gallons of paint.

The surface density of the lights on the Rockefeller Center Christmas Tree is 9.38 lights per square foot.

The surface density of the lights on the Rockefeller Center Christmas Tree can be found by dividing the total number of lights by the surface area of the tree.

To find the surface area of the tree, we need to first find the slant height of the cone. We can use the Pythagorean theorem to find the slant height, which is the square root of the sum of the height squared and the radius squared:

The slant height:

= sqrt(72^2 + (45/2)^2)

= 75.43 feet

The lateral area of a right cone can be found using the formula: πrs

r = 45/2 = 22.5 feet

Substituting the given values into the formula for the lateral area, we get:

Lateral area = π(22.5)(75.43)

Lateral area = 5329.1295 square feet

To find the surface density of the lights, we can divide the total number of lights by the lateral area:

Surface density = 50,000 / 5329.1295

Surface density = 9.38239537996

Surface density= 9.38 lights/square foot.
