Answer to this equation |z+3|=|z-2|

y√y i.e Option (B) is  equivalent to the expression below when y> 0.

Equivalent means that two things have the same value, meaning, or measure. For example, 2 + 2 and 4 + 0 are equivalent equations because both equal 4. Another example is 1/2 and 0.5, which are equivalent because they are both equal to one-half.Equivalent in mathematics refers to two expressions that have the same value or the same outcome when evaluated.

Equivalent means having the same value, measure, or effect as something else. For example, two dollars is equivalent to two euros.

Let's start with the expression:

√[tex]y^{3}[/tex]+√[tex]16y^{3}[/tex]-[tex]4y[/tex]√[tex]y[/tex]

where y > 0. (this allow us to have y inside a square root, so we don't mess with complex numbers).

We want to find the equivalent expression to this one.

Here, we can do the next two simplifications:

√[tex]16y^{3}[/tex] = √[tex]16[/tex] √[tex]y^{3}[/tex] = [tex]4[/tex]√[tex]y^{3}[/tex]

And

[tex]y[/tex]√[tex]y[/tex] = √[tex](y^{2}. y)[/tex]= √[tex]y^{3}[/tex]

If we apply these two to our initial expression, we can rewrite it as:

√[tex]y^{3}[/tex]+√[tex]16y^{3}[/tex]-[tex]4y[/tex]√[tex]y[/tex]

√[tex]y^{3}[/tex] + [tex]4[/tex]√[tex]y^{3}[/tex]-[tex]4[/tex]√[tex]y^{3}[/tex] = √[tex]y^{3}[/tex]=[tex]y[/tex]√[tex]y[/tex]

Therefore, Option (B) is correct.

Answer: is d

Step-by-step explanation:

Approximating to the nearest degree, θ = arccos(cosθ) ≈ 35°.

The angle between two vectors can be found using the dot product formula:

cosθ = (a⋅b)/(||a|| ||b||)

where ||a|| is the magnitude of vector a, and ||b|| is the magnitude of vector b.

First, let's find the magnitude of the vectors:

||a|| = √(4^2 + (-3)^2 + 1^2) = √(16 + 9 + 1) = √26

||b|| = √(2^2 + 0^2 + (-1)^2) = √5

Next, let's find the dot product of the vectors:

a⋅b = (4i−3j+k)⋅(2i−k) = 8i + 3j - k

Finally, let's substitute into the cosine formula:

cosθ = (a⋅b)/(||a|| ||b||) = (8i + 3j - k)/(√26 * √5)

To approximate the angle to the nearest degree, we can use the inverse cosine function:

θ = arccos(cosθ)

Note: The range of arccos is [0,180], so we need to use the appropriate quadrant to find the correct angle.

Answer:

x = 23

Step-by-step explanation:

let's square both sides. that eliminates the individual square roots and creates one central term with square roots :

2x + 3 + x + 2 - 2 sqrt(2x + 3)×sqrt(x + 2) = 4

3x + 5 - 2×sqrt((2x + 3)(x + 2)) = 4

3x + 1 - 2×sqrt(2x² + 4x + 3x + 6) = 0

3x + 1 - 2×sqrt(2x² + 7x + 6) = 0

3x + 1 = 2×sqrt(2x² + 7x + 6)

now let's square both sides again

9x² + 6x + 1 = 4(2x² + 7x + 6) = 8x² + 28x + 24

x² - 22x - 23 = 0

a quadratic equation

ax²x+ bx + c = 0

has 2 solutions

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (22 ± sqrt((-22)² - 4×1×-23))/(2×1) =

= (22 ± sqrt(484 + 92))/2 =

= (22 ± sqrt(576))/2 = (22 ± 24)/2 =

= 11 ± 12

x1 = 11 + 12 = 23

x2 = 11 - 12 = -1

since we squared twice in the process, and every solution to a square is a ±sqrt (so, 2 solutions with alternating signs), we need to try both solutions in the original equation to see which ones really fulfill it.

sqrt(2×23 + 3) - sqrt(23 + 2) = 2

sqrt(46 + 3) - sqrt(25) = 2

sqrt(49) - 5 = 2

7 - 5 = 2

correct, x = 23 is a valid solution.

sqrt(2×-1 + 3) - sqrt(-1 + 2) = 2

sqrt(-2 + 3) - sqrt(1) = 2

sqrt(1) - 1 = 2

1 - 1 = 2

wrong. so, x = -1 is not a valid solution to the original equation.

The first statement is false, the second is true, the third is true, and the fourth is false.

(a) False. A vector has infinitely many unit vectors parallel to it. A unit vector is a vector with magnitude 1 that points in the same direction as the original vector.

(b) True. The same segment/line can have many different parametrizations. A line/segment can be described by different equations, such as different parametric equations, and each of these equations represents the same line/segment.

(c) True. The sphere x² + y² + z² = 1 is a three-dimensional surface. The equation describes a set of points in three-dimensional space that are at a fixed distance of 1 from the origin.

(d) False. The magnitude of v + w is less than or equal to the magnitude of v and w. The magnitude of the sum of two vectors is equal to the distance between the tail of the first vector and the head of the second vector, which can never be greater than the magnitude of either vector.

There are no real solutions for this system of equations.

[tex](1)2x - 8y = 11\\ \\(2)x - 4y = 6[/tex]

For this solutions, we're going to solve equation (2) for variable "x".

[tex]x - 4y = 6[/tex]

Add "4y" on both sides of the equation.

[tex]x - 4y+4y = 6+4y \\ \\x=6+4y[/tex]

Calculated value: [tex]x=6+4y[/tex]

Equation to substitute in: [tex](1)2x - 8y = 11[/tex]

Substitution:

[tex]2(x) - 8y = 11\\ \\2(6+4y) - 8y = 11[/tex]

Simplify.

[tex]2(6+4y) - 8y = 11\\ \\(2)(6)+(2)(4y)-8y=11\\ \\12+8y-8y=11\\ \\12=11[/tex]

We obtained a false statement (12=11) which means that there's either no solution, or an infinite amount of solutions.

To see what's the exact case, try to make the coefficients of the equations be the same by multiplying one of the equation by a constant.

In this case, we could multiply all elements of equation (2) by number "2" in order to make the variables have the same coefficients as equation 1:

[tex]2(x - 4y = 6)\\ \\2x-8y=12[/tex]

Comparing the result to the other equation:

[tex]2x - 8y = 11\\ \\2x - 8y = 12[/tex]

There are no real solutions for this equations system, since the variables have the same coefficients and the contant terms are different (11 and 12).

Important note. If after multiplying the equation by a constant we had obtained the exact same equation, then we would've concluded that there where infinite solutions for the equations system.

An example of a derivative in accounting is a stock option.

The formula is Call Option Value = S * N(d1) - X * e^(-rT) * N(d2)

A derivative in accounting is a financial instrument whose value is derived from the value of one or more underlying assets, such as stocks, bonds, currencies, commodities, or real estate. One common example of a derivative in accounting is a stock option.

A stock option is a contract that gives the holder the right, but not the obligation, to buy or sell a specified number of shares of a stock at a specified price (the strike price) within a specified period of time. The value of a stock option is derived from the value of the underlying stock.

One formula used to calculate the value of a call option is the Black-Scholes model. The formula is as follows:

Call Option Value = S * N(d1) - X * e^(-rT) * N(d2)

Where:

S = the current stock price

X = the strike price

r = the risk-free interest rate

T = the time until expiration (in years)

N(d1) and N(d2) are the cumulative distribution functions of the standard normal distribution

For example, if a stock is currently trading at $50 per share, and the strike price of a call option on that stock is $45, with an expiration date of 1 year and the risk-free interest rate is 2%, the value of the call option can be calculated as follows:

Call Option Value = $50 * N(d1) - $45 * e^(-0.02*1) * N(d2)

N(d1) and N(d2) can be calculated using a financial calculator or software.

When multiplied by itself, a square root value equals the original value. There are four ways to calculate the square root: prime factorization, repeated subtraction, long division, and the estimation approach.

Using the square root function, you can convert rational numbers into algebraic numbers (which are a subset of rational numbers). The Euclidean norm (and distance) and generalizations like Hilbert spaces both depend on the square root of a nonnegative number.

Squares are the results of multiplying an integer by itself. Alternatively, the square root of an integer is a value that, when multiplied by itself, returns the original value.

The function of the temperature is H = 20cos(2π/12t) + 57

The temperature oscillates between 37°F at 6am and 77°F at 6pm,

So we can use the average of these two temperatures as the "midline" or "average" temperature (C).

The average temperature, C = (37+77)/2 = 57

The amplitude of the oscillation is half the difference between the maximum and minimum temperatures,

Amplitude, K = (77-37)/2 = 20

The period of the oscillation is the time it takes for the temperature to repeat, which is 24 hours.

i.e. T = 24

The angular frequency B is given by:

B= 2π/T

So we have B = 2π/24 = π/12

Finally, we can substitute these values into the formula H = Kcos(Bt) + C

H = 20cos(2π/12t) + 57
