Even though 2 is not a zero of the polynomial, p(k) = p(2) = 0.

No, 2 is not a zero of the polynomial p(x)=3x^(4)-14x^(3)-9x^(2)+64x-28. To determine p(k), we simply need to plug in the value of k into the polynomial and simplify.

So, p(k) = p(2) = 3(2)^(4) - 14(2)^(3) - 9(2)^(2) + 64(2) - 28

= 3(16) - 14(8) - 9(4) + 128 - 28

= 48 - 112 - 36 + 128 - 28

= 0

Therefore, p(k) = p(2) = 0.

So, even though 2 is not a zero of the polynomial, p(k) = p(2) = 0.

The correct way to name the figure shown is PQ. This figure consists of two perpendicular lines, P and Q, which intersect at a point. The lines are labeled P and Q, so the correct name for the figure is PQ.

Perpendicular lines are those two lines that intersect each other at a 90 degree angle. These lines are also known as orthogonal lines. When two lines intersect at a 90 degree angle, they are said to be perpendicular.

The figure is a basic geometric shape and is used to illustrate the concept of perpendicular lines. In the figure shown, the angle formed by the intersection of the two lines is a right angle, so the lines are perpendicular.

The figure can also be used to illustrate the concept of a transversal. A transversal is a line that intersects two other lines at different points. In the figure, the line PQ is a transversal intersecting the two lines P and Q.

In conclusion, the correct way to name the figure shown is PQ. This figure is used to illustrate the concepts of perpendicular lines, line segments, and transversals.

The area of the shaded segment of the circle is 5.79 square metre.

The area of a segment is equal to the area of a sector less the triangle-shaped portion.

A=[tex]\frac{1}{2}[/tex](∅-Sin∅)×[tex]r^{2}[/tex]

Every point in the plane of a circle, which is a closed, two-dimensional object, is evenly separated from the centre. All lines that cross the circle join together to produce the line of reflection symmetry. Moreover, every angle has rotational symmetry around the centre.

r=8m

x → -∞, f(x) → 0

x → ∞, f(x) → ∞

As x approaches negative infinity, the value of the exponent 2^x+1 will become very large negative number, approaching zero. Therefore, the function f(x) will approach 5 times zero, which is equal to 0. Thus, we can say:

As x → -∞, f(x) → 0.

As x approaches positive infinity, the value of the exponent 2^x+1 will become very large positive number, approaching infinity. Therefore, the function f(x) will approach 5 times infinity, which is equal to infinity. Thus, we can say:

Using two-point form, the equation of the line passing through the points A and B is x = 5.

The two-point form of a line is given by:
y - y₁ = [(y₂ - y₁)/(x₂ - x₁)] (x - x₁)
where (x₁, y₁) and (x₂, y₂) are two points on the line.

Given points A(5, 5) and B(5, -5), we can plug in the values into the equation:
y - 5 = [(-5 - 5)/(5 - 5)] (x - 5)

Simplifying the equation gives us:
y - 5 = (-10/0) (x - 5)

Notice that the slope (y₂ - y₁)/(x₂ - x₁) is equal to -10/0(indeterminate). This means that the line is a vertical line passing through x = 5.

The standard form of a line is Ax + By = C. So, the standard form of the equation of the line passing through points A and B is: x = 5.

As a result, after 14 years, the investment that was compounded interest irregularly will be valued $961.54 more than the one that was compounded yearly.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

We must apply the compound interest calculation in order to compare the values of the investment compounded annually with the investment compounded periodically:

[tex]A = P(1 + r/n)^(nt) (nt)[/tex]

where:

A is the total sum.

The principal is P. (the initial amount)

n is the number of times the interest is compounded each year, and r is the yearly interest rate (expressed as a decimal).

The number of years is t.

We have the following for the yearly compounded investment:

[tex]A = 9000(1 + 0.06/1)^(1*14) = $20,207.97[/tex]

Periodically compounded investment results in:

[tex]A = 9000(1 + 0.06/12)^(12*14) = $21,168.51[/tex]

As a result, after 14 years, the investment that was compounded irregularly will be valued $961.54 more than the one that was compounded yearly.

What is the fractions?

A fraction is a way of representing a part of a whole or a ratio between two numbers. It consists of a numerator (top number) and a denominator (bottom number), separated by a line.

If Ellie's house is at 1 1/2 on the number line, and Chase lives 1 1/5 blocks west of Ellie, then the coordinate of Chase's house would be:

1 1/2 - 1 1/5 = 3/2 - 6/5

To subtract these fractions, we need a common denominator, which is 10:

(3/2) * (5/5) - (6/5) * (2/2) = 15/10 - 12/10 = 3/10

So Chase's house is located 3/10 blocks west of Ellie's house on the number line. Therefore, the correct coordinate for Chase's house is:

Yearly compounding.
y = 2000(1.04)^t

Monthly compounding.

y = 2000(1 + r/12)^(12t)

2000(1.04)^t = 2000(1 + r/12)^(12t)

(1.04)^t = (1 + r/12)^(12t)

(1.04^t)^(1/t) = [(1 + r/12)^(12t)]^(1/t)

1.04 = (1 + r/12)^12

1.04^(1/12) = [(1 + r/12)^12]^(1/12)

1.00327374 = 1 + r/12

Suppose 2022 balls are randomly distributed into 100 boxes. Let X be the total number of balls in the first 20 boxes.  P(X = 90) ≈ 0.  VarX = 323.52.

a) To find P(X = 90), we can use the binomial probability formula:

P(X = k) = C(n,k) * p^k * (1-p)^(n-k)

where C(n,k) = n! / (k! * (n-k)!)

In this case, n = 2022, k = 90, p = 20/100 = 0.2

P(X = 90) = C(2022,90) * 0.2^90 * 0.8^(2022-90)

P(X = 90) = 1.19 * 10^(-37)

Therefore, P(X = 90) ≈ 0.


b) To find VarX, we can use the formula for the variance of a binomial distribution:

VarX = n * p * (1-p)

In this case, n = 2022, p = 0.2

VarX = 2022 * 0.2 * 0.8

VarX = 323.52

a. For the pessimistic approach, the recommended decision is to use the gradual introduction of the salad dressings, since it provides the least amount of loss should demand be low. For the minimax regret approach, the recommended decision is also the gradual introduction of the salad dressings, since it provides the lowest regret value should the demand be high.

Answer:

The angles are adjacent and the value of x is 63

Step-by-step explanation:

The x value where P(X < x)=0.0655 is 4 minutes. The correct answer is c. 3.96 minutes.

To find the x value where P(X < x)=0.0655, we can use the z-score formula and look up the corresponding z-value in a standard normal distribution table. The z-score formula is:

z = (x - mean) / standard deviation

Substituting the given values, we get:

0.0655 = (x - 10) / 4

Next, we can look up the z-value that corresponds to 0.0655 in a standard normal distribution table. We find that the z-value is approximately -1.5. Now we can plug this back into the z-score formula and solve for x:

-1.5 = (x - 10) / 4

-6 = x - 10

x = 4

The accountant is using two different models to estimate the tax expenditures for the small business. Both models assume that the tax expenditures are $5000 on January 1st, 2000. The accountant wants to estimate the tax expenditures, e, in thousands of dollars t years after January 1st, 2000.

Let's call the two models Model 1 and Model 2. Model 1 assumes that the tax expenditures increase by a fixed amount every year. Let's call this fixed amount a. Therefore, the tax expenditures, e, under Model 1 can be represented by the equation:

What is frequency ?

Frequency refers to the number of times that an event or value occurs within a specific period or dataset. It is a measure of how often a particular value or category appears in a set of data. The frequency can be expressed as an absolute count or as a proportion or percentage relative to the total number of observations in the dataset. Frequency is often used in statistical analysis to describe the distribution of data and to calculate various measures of central tendency and variability.

The relative frequency of a student being a tenth grader that gets their news from the internet is given by:
