A mathematically indication example would be to solve the equation 3x + 2 = 14 for the value of x. The solution would be 4.

Looking for a mathematically indication example, we can consider a simple mathematical equation with one variable and solve it.

The equation would be 3 x + 2 = 14.

So we can solve for the equation to be :

3x + 2 - 2 = 14 - 2

3x = 12

3 x / 3 = 12 / 3

x = 4

In conclusion, the mathematically indication example would be 3x + 2 = 14 and the value of x would be 4.

The right-hand limit of f(x) as x approaches 2 is 5.

To find the right-hand limit of the function f(x) as x approaches 2, we need to evaluate the function as x approaches 2 from the right-hand side (i.e., values of x greater than 2).

So, let's first rewrite the function:

\(f(x) = (x^2 + 2x - 3)/(x - 1)\)

Now, we can substitute x = 2 + h, where h is a small positive number, since we want to approach 2 from the right-hand side.

\(f(2 + h) = [(2 + h)^2 + 2(2 + h) - 3]/(2 + h - 1)\\= [(4 + 4h + h^2) + 4 + 2h - 3]/(1 + h)\\= (h^2 + 6h + 5)/(1 + h)\)

Now, we can evaluate the limit as h approaches 0 from the right-hand side:

lim (h→0+) f(2 + h) = lim (h→0+) \((h^2 + 6h + 5)/(1 + h)\)

= \([(0)^2 + 6(0) + 5]/(1 + 0)\)

= 5

The number of terms in a polynomial helps when performing operations like simplification, factoring, or evaluating expressions.

The polynomial 18x³ - 2x² + 4x - 1 consists of four terms.

In order to determine the number of terms in a polynomial, we count the number of distinct algebraic expressions separated by addition or subtraction operations.

In this polynomial, we have:

Term 1: 18x³ (This is the term with the highest degree, which is 3 in this case, and it includes the coefficient 18.)

Term 2: -2x² (This term has a degree of 2 and a coefficient of -2.)

Term 3: 4x (This term has a degree of 1 and a coefficient of 4.)

Term 4: -1 (This is a constant term with a degree of 0.)

Answer: The value of x is 9.

Step-by-step explanation: n a regular hexagon, all interior angles have the same measure.

Since a hexagon has six sides, the sum of its interior angles is given by the formula:

Sum of interior angles = (6 - 2) × 180° = 4 × 180° = 720°

Since all interior angles of a regular hexagon have the same measure, we can find the measure of each angle by dividing the sum by the number of angles:

Measure of each angle = Sum of interior angles / Number of angles = 720° / 6 = 120°

We are given that one of the angles in the hexagon is (11x + 21)°. Setting this equal to 120° and solving for x, we get:

11x + 21 = 120

11x = 99

x = 9

Therefore, the value of x is 9.

Answer:

\(-8x^3\sqrt{7}\)

Step-by-step explanation:

Step 1:  Let's start by simplifying -4x^2 * (√63x^2) using the following steps:

1.1: Separate √63x^2 into two terms:  

-4x^2 * (√63 * √x^2)

1.2:  Find the largest perfect square that we can factor out of 63.  It's 9 as 3^2 = 9 and 9 * 7 = 63.  Furthermore, √x^2 simplifies to x:

-4x^2 * (√9 * 7 * (x))

-4x^2 * (3√7 * x)

1.3:  We can multiply x and 3:

-4x^2 * (3x√7)

1.4:  We can distribute -4x^2 to 3x√7.  

-12x^3 * √7

Step 2:  Now we can work on simplifying x^3√112 using the following steps:

2.1:  Find the largest perfect square you can factor out of 112.  It's 16 since 4^2 = 16 and 16 * 7 = 112:

x^3 * √16 * 7

x^3 * 4√7

2.2:  Multiply x^3 and 4√7:
4x^3 * √7

Step 3:  Thus, -4x^2 * √63x^2 simplified individually is -12x^3 * √7 and x^3 * √112 simplified individually is 4x^3 * √7

3.1:  Add -12x^3 * √7 + 4x^3 * √7:

-8x^3√7

Optional Step 4:  We can check that we've correctly simplifed the equation by plugging in a number for x in both the radical expression not yet simplified and the simplified radical expression.  If we get the same answer, then we've simplified the expression correctly.  We can plug in 2 for x.

Plugging in 2 for x in -4x^2 * (√63x^2) + x^3 * (√112):

(1.) -4(2)^2 * √63(2)^2 + 2^3 * √112:

(2.) -4(4) * √63(4) + 8 * √112

(3.) -16 * √252 + 8 * √112

(4.) -16 * √36 * 7 + 8 *√16 * 7

(5.) -16 (6 * √7) + 8(4 *√7)

(6.) -96 * √7 + 32 * √7

(7.) -64√7

(8.) -169.3280839

Plugging in 2 for x in -8x^3√7:

(1.) -8(2)^3 * √7

(2.) -8(8) * √7

(3.) -64 * √7

(4.) -169.3280839

Therefore, we've correctly expressed the expression in simplest radical form

Answer:

Step-by-step explanation:

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Given: vector u = <2, -5> and vector v (3, 1)

Probability is simply how likely something is to happen. There can be many probability of the same thing to occur in future. the probability that a box of cereal will be:

A. The probability that a box of cereal will be more than one ounce underweight is equivalent to the probability of getting a weight less than 15 ounces. Using a standard normal distribution table or calculator, we can find that this probability is approximately 0.0228 or 2.28%.

B. The probability that a box of cereal will not be underweight is equivalent to the probability of getting a weight greater than or equal to 16 ounces. Using a standard normal distribution table or calculator, we can find that this probability is approximately 0.5 or 50%.

C. The likelihood that a package of cereal will weigh less than or equal to 17 ounces is the same as the likelihood that it won't be more than 1 ounce overweight. This chance can be calculated using a typical normal distribution chart or calculator as 0.9772 or 97.72%.

D. Because weight is a continuous variable with an infinitesimally tiny chance of attaining any precise value, the likelihood of receiving exactly 16 ounces is very low. The area under the normal distribution curve between 15.5 and 16.5 ounces, or roughly 0.3829 or 38.29%, can be used to determine the chance.

Answer:
\(3x-2+\frac{5}{x}\)

Step-by-step explanation:

To divide the polynomial (9x^3 - 6x^2 + 15x) by the monomial 3x^2, we can write it as:

(9x^3 - 6x^2 + 15x) ÷ (3x^2)

To simplify the division, we divide each term of the polynomial by 3x^2:

(9x^3 ÷ 3x^2) - (6x^2 ÷ 3x^2) + (15x ÷ 3x^2)

To divide monomials with the same base, we subtract the exponents. So:

9x^3 ÷ 3x^2 = 9/3 * (x^3/x^2) = 3x^(3-2) = 3x

(-6x^2) ÷ (3x^2) = -6/3 * (x^2/x^2) = -2

15x ÷ 3x^2 = 15/3 * (x/x^2) = 5/x

Putting it all together, we have:

(9x^3 - 6x^2 + 15x) ÷ (3x^2) = 3x - 2 + 5/x

Therefore, the division of (9x^3 - 6x^2 + 15x) by 3x^2 is 3x - 2 + 5/x.

The arc cossecant of the given value is of 30º.

The cosecant of an angle is given by the ratio between 1 and the sine of the angle, as follows:

cos(x) = 1/sin(x)
