We would name this polynomial as a quadratic polynomial with two terms.

A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on.

In the standard form of a polynomial, the terms are written in descending order of degree. The standard form for a polynomial of degree n is:

a1x + a0 + anxn + an-1xn-1 +...

We have the polynomial in this case:

9x² - 213

To write it in standard form, rearrange the terms in descending order of degree as follows:

213 + 9x²

As a result, the standard form of the polynomial is:

9x² - 213

This polynomial has degree 2 (because x's highest exponent is 2) and two terms (since there are two distinct parts to the expression, a constant and a term with an x squared coefficient).

As a result, we'd call this polynomial a quadratic polynomial with two terms.

Suppose that we randomly choose pens from a box that contains yellow and green pens until a yellow pen is obtained. Assume that each selected pen is replaced before the next one is drawn. In order to find the probability of picking up a pen at least three times, we need to use the probability formula.

For this problem, the probability of choosing a yellow pen on the first draw is P(Y) = number of yellow pens / total number of pens = y / (y+g), where y is the number of yellow pens and g is the number of green pens. The probability of not choosing a yellow pen on the first draw is P(NY) = g / (y+g).After selecting a pen, if it is not yellow, we need to select a pen again. The probability of selecting a pen that is not yellow on the second draw is the same as the probability of not selecting a yellow pen on the first draw, that is[tex]P(NY) = g / (y+g).[/tex]

Therefore,

the probability of choosing a yellow pen on the second draw is P(Y and NY) = [tex]P(Y) × P(NY) = y × g / (y+g)²[/tex].The probability of not choosing a yellow pen on the first two draws is P(NYY) = P(NY) × P(NY) = g² / (y+g)².To calculate the probability of choosing a yellow pen on the third draw, we need to consider two cases: the pen selected on the first two draws is green, and the pen selected on the first two draws is not green.

Case 1: The pen selected on the first two draws is green. The probability of selecting a yellow pen on the third draw is P(Y and NY and G) =[tex]P(Y) × P(NY) × P(G) = y × g × (y+g) / (y+g)³.[/tex]

Case 2: The pen selected on the first two draws is not green. The probability of selecting a yellow pen on the third draw is P(Y and NY and NY) = P(Y) × P(NY) × P(NY) = y × g² / (y+g)³.Therefore, the probability of picking up a pen at least three times is P(at least 3) = P(NYY) + P(Y and NY and G) + P(Y and NY and NY) = g² / (y+g)² + y × g × (y+g) / (y+g)³ + y × g² / (y+g)³ = g² / (y+g)² + 2y × g / (y+g)³.

The population of Toledo, Ohio is increasing at a rate of approximately 32,263 people per year after 10 years.

An exponential function is a mathematical function of the form f(x) = a^x, where "a" is a positive constant called the base, and "x" is a variable that can take on any real value. The base "a" is typically greater than 1, which means the function grows at an increasing rate as "x" increases.

a. The exponential function that relates the total population as a function of t is given by:

P(t) = P₀ × (1 + r)ᵗ

where P₀ is the initial population, r is the annual growth rate (as a decimal), and t is the time in years.

Using the given values, we have:

P₀ = 500,000 (given)

r = 0.05 (5% expressed as a decimal)

Answer:   A = Pe^(rt)

Where A is the amount of money at the end of the investment period, P is the principal amount, e is the mathematical constant e (approximately equal to 2.71828), r is the interest rate, and t is the time period.

In this case, we know that:

P = $720 (the initial investment)

A = $930 (the desired end amount)

t = 6 years (the investment period)

We can solve for r by rearranging the formula:

r = ln(A/P) / t

Where ln is the natural logarithm.

Plugging in the numbers, we get:

r = ln($930/$720) / 6

r = 0.0436 or 4.36%

Therefore, Jason would need an interest rate of approximately 4.36% (to the nearest hundredth of a percent) in order to end up with $930 after 6 years of continuous compound interest.

The height and radius of the cone that will use the smallest amount of paper are h ≈ 2.45 cm and r ≈ 1.22 cm, respectively.

The minimum paper will be used when the surface area of the cone is minimized. Let the height and radius of the cone be h and r, respectively. Then, using the formula for the volume of a cone, we have:

V = (1/3)πr^2h = 33 cm^3

Solving for h, we get:

h = 99/(πr^2)

Next, we need to express the surface area of the cone in terms of r. The surface area is given by:

A = πr√(r^2 + h^2)

Substituting the expression for h obtained above, we have:

A = πr√(r^2 + (99/πr^2)^2)

To find the value of r that minimizes A, we take the derivative of A with respect to r and set it equal to zero:

dA/dr = π(2r√(r^2 + (99/πr^2)^2) + (r^2 + (99/πr^2)^2)^(-1/2)(2r(99/πr^3)))

Setting dA/dr = 0 and solving for r, we get:

r = (33/(2π))^(1/4) ≈ 1.22 cm

Substituting this value of r back into the equation for h, we obtain:

h ≈ 2.45 cm

Therefore, the height and radius of the cone that will use the smallest amount of paper are h ≈ 2.45 cm and r ≈ 1.22 cm, respectively.

What is quadrilateral and parallelogram ?

A quadrilateral is a four-sided polygon, which means it is a closed shape with four straight sides. Some examples of quadrilaterals include rectangles, squares, trapezoids, and rhombuses.

A parallelogram is a special type of quadrilateral where both pairs of opposite sides are parallel. This means that the opposite sides never intersect, and they have the same slope. Additionally, the opposite sides of a parallelogram are congruent (i.e., have the same length), and the opposite angles are also congruent. Some examples of parallelograms include rectangles, squares, and rhombuses.

To prove that a quadrilateral is a parallelogram, we need to show that both pairs of opposite sides are parallel. Knowing that AB = DC only gives us information about the lengths of the sides, but it doesn't tell us anything about their orientation or whether they are parallel.

If the value of the Bulls Eye stock has fallen 8% annually since 2010, it will be worth $32.90 in 2015.

The formula Profit = Selling Price - Cost Price can be used to determine the profit when the selling price and the cost price of a product are known. The formula for calculating profit percentage is then applied, which is profit percentage = (profit/cost price) x 100.

If the value of the Bulls Eye stock has dropped by 8% annually, it has dropped to 92% (100% - 8%) of its value from the prior year.

Since we're moving from 2010 to 2015, we must multiply this loss five times to determine the stock's value in 2015:

Value in 2011 = 92% of $50 = $46

Answer:

Let's start by defining our variables:

Now, let's write the system of inequalities to represent the constraints:

The company has 260 boards of mahogany, so x ≤ 260.

The company has 320 boards of black walnut, so y ≤ 320.

The company expects to sell at most 380 boards, so x + y ≤ 380.

We cannot sell a negative number of boards, so x ≥ 0 and y ≥ 0.

Graphically, these constraints represent a feasible region in the first quadrant of the xy-plane bounded by the lines x = 260, y = 320, and x + y = 380, as well as the x and y axes.

To maximize profit, we need to write a function that represents the objective. The profit for selling one board of mahogany is $20, and the profit for selling one board of black walnut is $6. Therefore, the total profit P can be calculated as:

To maximize P, we need to find the values of x and y that satisfy the constraints and make P as large as possible. This is an optimization problem that can be solved using linear programming techniques.

The solution to this problem can be found by graphing the feasible region and identifying the corner point that maximizes the objective function P. However, since we cannot draw a graph here, we will use a table of values to find the maximum profit.

Let's consider the corner points of the feasible region:

Corner point (0, 0):

P = 20(0) + 6(0) = 0

Corner point (260, 0):

P = 20(260) + 6(0) = 5200

Corner point (0, 320):

P = 20(0) + 6(320) = 1920

Corner point (100, 280):

P = 20(100) + 6(280) = 3160

Corner point (200, 180):

P = 20(200) + 6(180) = 5520

Corner point (380, 0):

P = 20(380) + 6(0) = 7600

The maximum profit is $7600, which occurs when the company sells 380 boards of wood, all of which are mahogany.

16 four digit positive integers x are there with the property that x and 3x have only even digits.

There are 16 such four-digit positive integers x.

At first we have to find the four-digit positive integers x with the property that both x and 3x have only even digits, we need to consider the possible digits that x can have.

Since both x and 3x must have only even digits, the digits of x can only be 0, 2, 4, 6, or 8.

Let, the possible cases for the first digit of x:

If the first digit of x is 0:

In this case, x would be a three-digit number (e.g., 012, 024, 036, etc.). Now, if we multiply any three-digit number by 3, the resulting number will always have at least one odd digit.

we get, this case does not satisfy the condition.

If the first digit of x is 2 or 8:

In this case, the last digit of 3x will be 6 or 4, respectively. But since 6 is not an even digit and 4 is not a valid digit for x, this case is not possible either.

If the first digit of x is 4 or 6:

In this case, the last digit of 3x will be 2 or 8, respectively.

These are valid digits for x.

Now, we need to make sure that the second digit of x and 3x are also even.

The only even digits that can be used as the second digit are 0 and 8 (because 2 and 6 are already used as the first digit).

So, there are two possible cases for the first digit of x: 4 or 6.

Now, we have two choices for the second digit of x (0 or 8).

For each of these combinations, we have two choices for the third digit of x (0 or 8).

Finally, we have two choices for the fourth digit of x (0 or 8).

So, we get the total number of four-digit positive integers x with the property that both x and 3x have only even digits is:

Number of choices = 2 (choices for the first digit) * 2 (choices for the second digit) * 2 (choices for the third digit) * 2 (choices for the fourth digit) = 2⁴ = 16.

Answer:

X≈ 2,37 cm

x= (-11+√637)/6 cm

Step-by-step explanation:

The perimeter of the parallelogram is 68 and the length of AC is 15.

From the question, we are to calculate the perimeter of the parallelogram and the length of AC

First,

Let half the length of AC be x

Then,

From the Pythagorean theorem, we can write that

17² = x² + 8²

289 = x² + 64

x² = 289 - 64

x² = 225

x = √225

x = 15

Recall,

x = 1/2 AC

Therefore,

AC = 2x

AC = 2(15)

AC = 30

To calculate the perimeter, we will determine the length of BC

|BC|² = x² + 8²

|BC|² = 225 + 64

|BC|² = 289

|BC| = √289

|BC| = 17

The tree diagram with probabilities that  shows all possible outcomes for Yusuke's situation is mentioned below .

A tree diagram is a visual tool used to represent hierarchical structures or relationships.

It consists of a branching structure where each branch represents a different category or possibility, allowing for easy visualization of complex systems or decision-making processes.

                   LB (+)                                   LB (-)

Test (+)     0.045 (true)                         0.055 (false positive)

Test (-)      0.005 (false negative)        0.895 (true negative)

The probabilities are as follows:

0.05 (5%) of the students have LB, and therefore the probability of Yusuke having LB is 0.05.

The blood test detects LB accurately 90% of the time, meaning that the probability of a correct positive test result (i.e., Yusuke has LB and the test detects it) is 0.05 * 0.9 = 0.045.

The probability of a false positive test result (i.e., Yusuke does not have LB but the test detects it) is 0.95 * 0.1 = 0.055.

The probability of a true negative test result (i.e., Yusuke does not have LB and the test does not detect it) is 0.95 * 0.9 = 0.855.

The probability of a false negative test result (i.e., Yusuke has LB but the test does not detect it) is 0.05 * 0.1 = 0.005.

Note that the sum of the probabilities for each possible outcome (i.e., correct positive, false positive, true negative, false negative) should add up to 1.
