Answer:

Step-by-step explanation:

Solving by factoring is a strategy for solving a polynomial equation that is in quadratic form. Quadratic form means that the equation is of the form ax^2+bx+c=0, where a,b, and c are real numbers. When factoring, the goal is to express the equation as the product of two simpler equations. To do this, we must factor the quadratic equation into two linear equations, each with a single variable.

For example, consider the equation x^2+3x-4=0. To factor this equation, we can first rewrite it as (x+4)(x-1)=0. This is the same as x+4=0 and x-1=0. We can then solve each of these linear equations to find the solutions. In this case, the solutions are x=-4 and x=1.

Therefore, the strategy of solving by factoring is to rewrite a polynomial equation in quadratic form as the product of two simpler equations, and then solve each of these equations. The solutions to the original equation can then be found by solving each of the linear equations.

The vertex form of the equation of the parabola is the quadratic equation y - 3 = - 3 · (x + 4)².

Parabolae are represented by quadratic equations, there are two forms for such equations: (i) standard form, (ii) vertex form. The vertex form of the equation of the parabola is shown below (please notice that parabola is parallel to y-axis when axis of symmetry is a vertical line):

y - k = C · (x - h)²

Where:

If we know that h = - 4, k = 3 and (x, y) = (- 3, 0), then the equation of the parabola in vertex form is:

C = (y - k) / (x - h)²

C = (0 - 3) / [(- 3) + 4]²

Answer: -81a^2 + 27a + 10

Step-by-step explanation: We can do this question by using FOIL (first, outer, inner, last)

(-9a-2)(9a-5)

First, multiply the first two terms in the parentheses

-9a times 9a is -81a^2

Second, multiply the outer terms

-9a times -5 is 45a

Third, multiply the inner terms

-2 times 9a is -18a

And lastly, multiply the last terms

-2 times -5 is 10

After doing this we end up with -81a^2 + 45a - 18a + 10 = -81a^2 + 27a + 10

Using the given information, the measure of angle AEB is 62

From the question, we are to determine the measure of angle AEB

From the given information, we have that

Angle A = 86°

Angle C = 110°

Angle D = 40°

First, we will calculate the measure of angle B

A + B + C + D = 360°

86 + B + 110 + 40 = 360 (Sum of angles in a quadrilateral)

B + 236 = 360

B = 360 - 236

B = 124

∴ Angle ABC = 124

Then,

Angle ABC is bisected

Therefore,

Angle AEB = 1/2 × 124

Angle AEB = 62

Hence, angle AEB is 62

The average cost of your item, based on a gross margin of 3%, is $108.20.

The average cost is the cost per unit.

It can be computed as the quotient of the total cost and the number of units.

The gross margin is the percentage difference between the cost of goods sold and the sales revenue.

The gross margin percentage is expressed as a quotient of the sales revenue multiplied by 100.

Selling price = $111.55

Gross margin = 3%

Selling price = 100%

Cost of goods sold = 97% (100 - 3)

Average cost (cost per unit) = Selling Price x Percentage Cost/Selling Price Percentage

$108.20 ($111.55 x 97/100)

Thus, the average cost of the product is $108.20.

The given angle 2.59 radian into degree is 148.40°.

What is radian and degree?

While a radian is another unit of measurement that is used to measure angles, a degree is a unit of measurement that is used to measure circles, spheres, and angles. The radian, or one pi radian, is only half the diameter of a circle, which has 360 degrees, or its entire area.

Given:

The angle in radian is 2.59.

We have to convert this angle into degree.

Since, the formula to convert angle θ from radian to degree is,

Radian = [tex]\frac{180}{\pi }[/tex] degree

= 2.59 x (180/π)

= 148.40°

Hence, the given angle 2.59 radian into degree is 148.40°.

Answer:

D) 7/12

Step-by-step explanation:

The first thing we want to do is find a like denominator for the fraction

Both 4 and 3 go into the multiple 12, so we'll use that

4x3=12

3x4=12

and what you do to one side, you must do to the other so we have

1/4x3= 3/12

2/3x4= 8/12

With that you get 2 3/12 and 1 8/12, which is subtractable

Take one from 2 so that you can make 3/12 15/12

15/12-8/12=7/12

Verdadero. Cuando hay una potencia de una potencia, se conserva la base y los exponentes se multiplican.

Para calcular la potencia de una potencia, se puede conservar la base y multiplicar los exponentes. Esto se basa en la propiedad matemática de la potenciación que establece que (a^b)^c = a^(b*c), donde a es la base, b es el primer exponente y c es el segundo exponente.

Por ejemplo, considere (2³)⁴. La base es 2 y el primer exponente es 3 y el segundo exponente es 4. El resultado sería 2^(3*4) = 2¹². Esto significa que la expresión original (2³)⁴ es igual a 2 elevado a la potencia de 12.

En general, cuando se tiene una potencia de una potencia, el resultado se obtiene conservando la base y multiplicando los exponentes. Esto permite simplificar la expresión y encontrar el resultado de manera más fácil.

Answer:

m∠10 = 41°

Step-by-step explanation:

If ∠9 and ∠10 are complementary. Then ∠7 and ∠8 are complementary as well. Complementary angles meameansns they sum up to 90 degrees.

m∠7 + m∠8 = 90

m∠7 + 41 = 90

m∠7 = 90 - 41 = 49°

Given that m∠7 ≅ m∠9. So m∠9 = 49° and m∠10 = 41°.

The Law of Sines The law of trigonometric functions, sine law, sine formula, or sinusoidal rule is a trigonometric equation that relates the sizes of any triangle's edges to the sines of its orientations.

The sine law in the triangle ΔABC is given as,

AB / sin C = BC / sin A = AC / sin B

In triangle ABC, ∠A = 25°, ∠C = 55° and AB = 60. Then the third angle is given as,

∠A + ∠B + ∠C = 180°

25° + ∠B + 55° = 180°

∠B = 100°

60 / sin 55° = BC / sin 25°

BC = 30.955

BC ≈ 31

60 / sin 55° = AC / sin 100°

AC = 72.134

Answer: the probability that a student chosen at random plays the bass is 1/3 in simplest form.

Step-by-step explanation:

The probability of an event can be found by taking the number of favorable outcomes and dividing it by the total number of outcomes. In this case, we are looking for the probability that a student chosen at random plays the bass.

We know that there are a total of 6 + 4 + 7 + 2 = 19 seventh grade students and 4 + 15 + 13 + 6 = 38 eighth grade students. So there are a total of 19 + 38 = 57 students.

We also know that there are 4 seventh grade bass players and 15 eighth grade bass players, for a total of 4 + 15 = 19 bass players.

So, the probability that a student chosen at random plays the bass is 19/57. This fraction can be simplified by dividing both the numerator and denominator by their greatest common factor which is 19/57 = 1/3.

So, the probability that a student chosen at random plays the bass is 1/3 in simplest form.
