What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form. A non-zero term (a 0) for the coefficient of x2 is a prerequisite for an equation to be a quadratic equation. The x2 term is written first, then the x term, and finally the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of letters a, b, and c are expressed as integral values rather than fractions or decimals.

To find the zeros of the function [tex]y=7x^3-7x[/tex], we can set y equal to zero and solve for x:

[tex]7x^3 - 7x = 0[/tex]

Factor out 7x:

[tex]7x(x^2 - 1) = 0[/tex]

Factor the quadratic expression:

7x(x - 1)(x + 1) = 0

The zeros of the function are the values of x that make y equal to zero. From the factored expression, we see that the zeros are:

x = 0 (with multiplicity 1)

x = 1 (with multiplicity 1)

x = -1 (with multiplicity 1)

Therefore, the correct choice is: The numbers 0, 1, and -1 are zeros of multiplicity 1.

Step-by-step explanation:

remember, the general equation for a circle is

(x - h)² + (y - k)² = r²

r is the radius, (h, k) is the center point of the circle.

the line (0, 8) to (0, -2) is a diameter, so, the center of the circle is the midpoint between both points.

remember, the midpoint between 2 points (x1, y1) and (x2, y2) is

((x1+x2)/2, (y1+y2)/2)

in our case :

((0+0)/2, (8-2)/2) = (0, 3)

the distance from the center point to the endpoint is e.g

(0, 3) to (0,8) = 8-3 = 5.

and that is the radius.

the equation of the circle is therefore :

(x - 0)² + (y - 3)² = 5²

x² + (y - 3)² = 25

The probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To determine P(at least 2 tails), we need to add up the probabilities of all the outcomes in the sample space that have at least 2 tails.

Looking at the tree diagram, we can see that there are 11 outcomes that have at least 2 tails:

TTTT TTTH TTHT TTHH THTT THHT THTH HTTT HTTH HTHT HHTT

The probability of each outcome can be found by multiplying the probabilities along the branches that lead to that outcome. Since the coin is fair, the probability of getting heads or tails on any given toss is 1/2.

So for example, the probability of the outcome TTHH is (1/2) x (1/2) x (1/2) x (1/2) = 1/16.

We can find the probability of getting at least 2 tails by adding up the probabilities of the 11 outcomes listed above:

P(at least 2 tails) = [tex](1/2)^4[/tex] + 4 x [tex](1/2)^3[/tex] x (1/2) + 6 x [tex](1/2)^2[/tex] x [tex](1/2)^2[/tex]

P(at least 2 tails) = 1/16 + 4/16 + 6/16 = 11/16

Therefore, the probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.

the amount closest to the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is $22.32.

What is compound interest?

The interest on savings that is computed on both the initial principal and the interest accrued over time is known as compound interest. Compound interest is computed by multiplying the starting principal amount by one and the annual interest rate is raised to the number of compound periods minus one. The final step is to deduct the initial loan principal from the calculated value.

Using the formula for compound interest, we can find the amount at the end of 4 years in Account B:

[tex]A = P * (1 + r/n)^{(nt) = $1500 * (1 + 0.035/1)^{(14) = $1732.32[/tex]

The interest earned in Account B over 4 years is the difference between the amount at the end of the period and the principal:

I = A - P = $1732.32 - $1500 = $232.32

Therefore, the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is approximate:

$232.32 - $210 = $22.32

Therefore, the amount closest to the difference between the interest Victoria would earn in Account B and the interest she would earn in Account A at the end of 4 years is $22.32.

As a result, the following is the given function's Fourier transform:

F(ω) = (1/π) * (sin(ω) / ω)

The Fourier transform is a mathematical operation that separates the frequencies that make up a waveform, which is a function of time. The Fourier transform's output is a complex valued function of frequency.

We must assess the integral in order to determine the given function's Fourier transform, f(x):

F() is equal to 1/(2) * [from - to -] F(x) E(-i) X Dx

where the frequency parameter is and i is the fictitious unit.

We can simplify the integral bounds as follows since the function f(x) is non-zero only in the range -1 x 1.

F() is equal to 1/(2)*[from -1 to 1] F(x) E(-i) X Dx

Let's analyse this integral in stages.

The value of the function f(x) is zero for x -1 or x > 1. As a result, we can increase the integral limits to - and + without changing the integral's value:

F(ω) = 1/(2π) * ∫(from - to -) F(x) = E(-ix) dx = 1/(2*) * the range [- to -1] from -1 to 1 + 0 dx 2dxe(-ix)+[from 1 to ] 0 dx = 1/(2π) * 2 * ∫E(-ix) dx [from -1 to 1]

∫[in the range of -1 to 1] e(-ix) dx = (-1/i)* [e^(-iωx)](-1/i)* _[from -1 to 1] (e^(-iω) - e^(iω))

Adding this back into the formula for the Fourier transform results in:

F(ω) = 1/(2π) * 2 * (-1/iω) * (e^(-iω) - e^(iω)) = (1/π) * (sin(ω) / ω)

To find the Fourier transform of the given function f(x), we need to use the following formula:

F(ω) = ∫ f(x) e^(-iωx) dx

where F(ω) denotes the Fourier transform of f(x) and ω is the frequency variable.

It seems that the given data consists of two sets of numbers separated by an equals sign. The first set of numbers appears to be a list of math test scores, while the second set of numbers is unclear.

Assuming that the question is asking about the number of students represented by the first set of numbers (the math test scores), then the answer would be 31. This is because there are 31 numbers in the list, which could represent the scores of 31 individual students.

Answer: 31

Step-by-step explanation:

To solve this problem, we can use the combination formula, which is:

n C r = n! / (r! * (n-r)!)

where n is the total number of students eligible for the committee, r is the number of students we want to choose, and ! denotes the factorial function.

In this case, we want to choose a committee of 8 students from a pool of 8 freshmen, 9 sophomores, 8 juniors, and 10 seniors. So, the total number of students eligible for the committee is:

n = 8 + 9 + 8 + 10 = 35

We want to choose a committee of 8 students, so r = 8. Therefore, the number of ways we can choose a committee of 8 students is:

35 C 8 = 35! / (8! * (35-8)!) = 35! / (8! * 27!) ≈ 1,121,112 ways

So there are approximately 1,121,112 ways to choose a dance committee of 8 students from the eligible pool.

According to the given data the maximum profit is $780,000 when 6,500 bikes are sold.

The marginal profit function represents the rate at which the profit changes as the number of units sold changes. It is the derivative of the profit function with respect to the number of units sold. The marginal profit function is important in business because it helps companies to determine the optimal level of production that maximizes profit. The critical value of the marginal profit function (when it equals zero) indicates the point where the profit function changes from increasing to decreasing, or vice versa, which can help companies to identify the optimal production level that maximizes profit.

a) To find the marginal profit function, we need to take the derivative of the profit function with respect to x:

P'(x) = -4x + 260

b) To find the critical value, we need to set the marginal profit function equal to zero and solve for x:

-4x + 260 = 0

x = 65

Therefore, the critical value is x = 65.

c) To find the maximum profit, we need to evaluate the profit function at the endpoints of the given interval (3 and 80) as well as at the critical value (65), and then compare the values to see which one is the largest. We can use a table to organize the values:

Step-by-step explanation:

We are given a triangle, and we know that the angles in the triangle are <A, <B, and <C.

We know that m<A = 78° and  m<B=45°. We want to find the measure of angle C, which we know currently as x.

Recall that all angles in a triangle add up to 180°. This means that m<A + m<B + m<C = 180°.

Substituting what we know into that equation, we get:

We can add 78 and 45 degrees together.

123° + x = 180°

Subtract 123° from both sides.

x = 57°

So x, or m<C is 57°.

To find the LCM of the two expressions, we need to factor each expression completely and then take the product of the highest powers of each factor.

So, let's factor each expression:

6(x – 1)2(x + 2)(x – 3) = 2 × 3 × (x – 1) × (x – 1) × (x + 2) × (x – 3)

9(x – 1)(x + 2)2(x – 3) = 3 × 3 × (x – 1) × (x + 2) × (x + 2) × (x – 3)

Now, we can identify the highest powers of each factor.

The LCM will be the product of those highest powers:

LCM = 2 × 3 × 3 × (x – 1)2 × (x + 2)2 × (x – 3)

Therefore, the LCM of 6(x – 1)2(x + 2)(x – 3) and 9(x – 1)(x + 2)2(x – 3) is 54(x – 1)2(x + 2)2(x – 3).
