What's the expression of this?

Therefore, the total tax owed by a Single filer with a taxable income of equation $57,000 for the tax year 2021 is $995 + $3,669 + $3,844.50 = $8,508.50.

When two assertions are connected by a mathematical equation, the equals symbol (=) is used to denote equality. In algebra, a mathematical statement that establishes the equivalence of two mathematical expressions is referred to as an equation. In the equation 3x + 5 = 14, for instance, the equal sign places a space between the integers 3x + 5 and 14. To comprehend the connection between the two phrases written on the opposing sides of a letter, utilise a mathematical formula. Frequently, the logo and the specific piece of software are the same. as in, for instance, 2x - 4 = 2.

Assuming that the taxable income of $57,000 is for the tax year 2021 and the person is filing as Single, we can use the following marginal tax rates to compute the tax owed:

Tax Rate Taxable Income Range

10% $0 - $9,950

12% $9,951 - $40,525

22% $40,526 - $86,375

24% $86,376 - $164,925

32% $164,926 - $209,425

35% $209,426 - $523,600

37% $523,601 or more

To compute the tax owed, we need to apply each tax rate to the corresponding portion of the taxable income and add up the results. Here's how we can do that:

The first $9,950 of taxable income is taxed at 10%, so the tax on this portion is $9950 x 0.1 = $995.

The next $30,575 ($40,525 - $9,950) of taxable income is taxed at 12%, so the tax on this portion is $30,575 x 0.12 = $3,669.

The remaining $17,475 ($57,000 - $40,525) of taxable income is taxed at 22%, so the tax on this portion is $17,475 x 0.22 = $3,844.50.

Therefore, the total tax owed by a Single filer with a taxable income of $57,000 for the tax year 2021 is $995 + $3,669 + $3,844.50 = $8,508.50.

The given indicates that the decimal of growth or decay is 0.69 for this problem. Decimal of growth or decay can be determined using the formula A = P(1+r)ⁿ.

Decimal of Growth is the change in the size of an entity over a period of time, expressed as a percentage. It is a measure of the rate at which something grows or shrinks.

Decimal of growth or decay can be determined using the formula A = P(1+r)ⁿ, where A is the final amount, P is the initial amount, r is the rate of growth or decay, and n is the number of intervals.

In this case, A=7,545, P=7,545, r=0.96, and n=5. Plugging these values into the formula, we get 7,545=(7,545)(1+0.96)⁵.

Using a calculator, we can determine that (1+0.96)⁵=0.69, resulting in A=7,545(0.69)=5,203. This indicates that the decimal of growth or decay is 0.69 for this problem.

Given that the polynomial has a zero at 5 with multiplicity 2, its complete factorization is (x - 5)²(z + 9)(z - 2).

To factor the given polynomial z⁴ - 3z³ - 63z² + 355z - 450, given that it has a zero at 5 with multiplicity 2, we can use the fact that (z - 5)² is a factor of the polynomial. We can then use synthetic division to find the other factors.

First, we divide the polynomial by (z - 5) using synthetic division:
5   |   1  -3  -63  355  -450
    |       5    10  -265  450
        1   2  -53    90       0

The result of the division is z³ + 2z² - 53z + 90 . Divide it by (z - 5) again since the multiplicity is 2.
5   |   1   2  -53    90
    |       5    35   -90

        1   7   -18      0

The result of the second division is z² + 7z - 18. This polynomial can still be factorized as (z + 9)(z - 2).

So, the final answer is:

z⁴ - 3z³ - 63z² + 355z - 450 = (x - 5)²(z + 9)(z - 2).

The solution of the exponential equation is x = 0.35

An exponential equation is an equation that contains exponents.

Since we have the exponential equation

4ˣ = 8ˣ - 1

We proceed to solve as follows

4ˣ = 8ˣ - 1

(2²)ˣ = (2⁴)ˣ - 1

(2ˣ)² = (2ˣ)⁴ - 1

Let 2ˣ = y

So, we have that

y² = y⁴ - 1

Re- arranging, we have that

y⁴ - y² - 1 = 0

Also, let y² = p. So, we have that

p² - p - 1 = 0

Now, we find p using the quadratic formula.

[tex]p = \frac{-b +/-\sqrt{b^{2} - 4ac} }{2a}[/tex]

where a = 1 b = -1 and c = -1

So, [tex]p = \frac{-(-1) +/-\sqrt{(-1)^{2} - 4(1)(-1)} }{2(1)}\\= \frac{1 +/-\sqrt{1 + 4} }{2}\\= \frac{1 +/-\sqrt{5} }{2}\\p = \frac{1 + 2.24 }{2} or p = \frac{1 - 2.24 }{2}\\p = \frac{3.24 }{2} or p = \frac{-1.24 }{2}\\p = 1.62 or p = -0.62[/tex]

We ignore the negative value.

So, p = 1.62

y² = 1.62

y = ±√1.62

y = ±1.273

Since y = 2ˣ, we have that

2ˣ = ±1.273

We ignore the negative value since the value of y cannot be negative.

So, 2ˣ = 1.273

Taking natural logarithm of both sides, we have that

㏑2ˣ = ㏑1.273

x㏑2 = ㏑1.273

x = ㏑1.273/㏑2

= 0.2412/0.693

= 0.348

≅ 0.35

The equation of the parabola can be written as

y=-0.16(x+2.0)(x-4.6)

A parabola is a curve made from the conic section whose eccentricity is 1 and is defined by the linear equation,

y=a(x-h)²+k, where a is an arbitrary constant and (h,k) denotes the vertex of the parabola.

According to the Intercept form of a parabola, if two x-intercepts (h1, 0), (h2, 0) are given, then the equation of parabola can be written as,

y=a(x+h1)(x-h2)

In this question,

h1 = 2.0

h2 = 4.6

So, the equation of the parabola would be,

y=a(x+2.0)(x-4.6)

Now, to find the value of the arbitrary constant "a", we can plug the point (0, 1.5) in this equation,

1.5 = a(0+2.0)(0-4.6)

1.5 =  a(-9.2)

a = -0.16

The addends in the table are as follows:

1/10 + 1/5 = 3/10, 1/5 + 1/5 = 2/5

3/10 + 1/5 = 1/2

We can observe that the first two pairs of addends add up to 1/5 less than the subsequent sums. This pattern indicates that the missing addend must be

1/5 - 1/10 = 1/10

We have to, A is linearly dependent for all values of c, the set of all vectors of the form (2a + b + c, 2a + 2b, 0) and the only value of c for which (4, 1, 3) is in Span(A) is c = 1.

a) A is linearly dependent for all values of c because there are more vectors than there are dimensions in the vector space. This means that one of the vectors can be expressed as a linear combination of the other vectors. Specifically, the vector (0, 0, c) can be expressed as a linear combination of the other vectors: (0, 0, c) = c*(2, 2, 0) + 0*(1, 2, c) + 0*(1, 0, 0).

b) For c = 0, the set of vectors A becomes {(2, 2, 0),(1, 2, 0),(0, 0, 0),(1, 0, 0)}. The span of this set of vectors is the set of all linear combinations of these vectors. Since the third vector is the zero vector, it does not contribute to the span. The span of the remaining vectors is the set of all linear combinations of the form a*(2, 2, 0) + b*(1, 2, 0) + c*(1, 0, 0). This is the set of all vectors of the form (2a + b + c, 2a + 2b, 0), which is a plane in R3 that contains the origin and is parallel to the xy-plane.

c) To find all values of c for which (4, 1, 3) is in Span(A), we need to find all values of c for which there exist scalars a, b, and d such that (4, 1, 3) = a*(2, 2, 0) + b*(1, 2, c) + d*(1, 0, 0). This gives us the following system of equations:2a + b + d = 42a + 2b = 1bc = 3We can solve this system of equations to find the values of a, b, and c. From the first equation, we can express d in terms of a and b: d = 4 - 2a - b. Substituting this into the second equation gives us 2a + 2b = 1 - 4 + 2a + b, which simplifies to b = 3. Substituting this value of b back into the third equation gives us 3c = 3, which gives us c = 1. Therefore, the only value of c for which (4, 1, 3) is in Span(A) is c = 1.

A store scanner has a red laser wavelength of 650 nm. While a green laser pointer has a wavelength of 502 μm. The ratio of green to red wavelengths is 0.77.

To find this ratio, we need to divide the wavelength of the green laser by the wavelength of the red laser:

502 μm / 650 nm = 0.77

Note that we need to convert the units of the green laser wavelength from micrometers (μm) to nanometers (nm) in order to divide it by the red laser wavelength, which is already in nanometers. To do this, we multiply the green laser wavelength by 1000:

502 μm * 1000 = 502000 nm

So the ratio of green to red wavelengths is 502000 nm / 650 nm = 0.77.

This ratio indicates that the green laser has a shorter wavelength than the red laser. Generally, shorter wavelengths correspond to higher energy and higher frequency light. In the case of lasers, this means that the green laser is capable of producing a more intense and focused beam of light than the red laser.

The vector that is perpendicular to the tangent vector of the curve at (0, 1, 0) is <1, 0, -1>, or option c

The space curve given is r(t) = sin t i + e^t j + ln(t+1) k. To find the tangent vector of the curve at a given point, we need to take the derivative of the curve with respect to t. The derivative of the curve is r'(t) = cos t i + e^t j + (1/(t+1)) k.

At the point (0, 1, 0), t = 0. So, the tangent vector at this point is r'(0) = cos 0 i + e^0 j + (1/(0+1)) k = <1, 1, 1>.

Now, we need to find which of the given vectors is perpendicular to the tangent vector. Two vectors are perpendicular if their dot product is equal to 0. So, we need to find the dot product of the tangent vector with each of the given vectors and see which one is equal to 0.

    Since the first equation uses a ≤ symbol, we know we will use a solid line. This is because it is less than and equal to. Then, we will graph it as a regular slope-intercept line.

    This line has a slope of 5 and a y-intercept of -2. This means we will start at (0, -2) and move five units up for every unit right, or five units down for every unit left.

    For the next equation, it uses a > symbol so we will use a dashed line. This is because it is not equal to, only greater than. Same as the previous. We will graph it as a slope-intercept line, but using a dashed line instead of a solid line.

    This line has a slope of -2 and a y-intercept of positive 5. This means we will start at (0, 5) and move two units down for every unit right, or two units up for every unit left.

The statements that are true about the function when graphed on a coordinate plane include the following:

C. The relative minimum of the function is (3, 0)

E. When t > 3, the function is increasing.

In order to determine the minimum and maximum of this function, we would have to determine the critical points where the derivative of the function is equal to zero or undefined, and then evaluate the function at these critical points and at the endpoints of the interval.

By taking the first derivative of the given function and factorizing, we have:

f(t) = t³ - 6t² + 9t

f'(t) = 3t² - 12t + 9  

3t² - 12t + 9 = 0

t² - 4t + 3 = 0

(t - 3)(t - 1) = 0

t = 3 and t = 1

Therefore, the critical points of the function are at t = 1 and t = 3.

By taking the second derivative of the given function and factorizing, we have:

f''(t) = 6t - 12

At point t = 1, we have:

f''(1) = 6(1) - 12 = -6 (it is less than zero).

Therefore, f(t) has a local maximum at t = 1.

At point t = 3, we have:

f''(3) = 18 - 12 = 6 (it is greater than zero).

Therefore, the function f(t) has a local minimum at t = 3.

At t = 4, f''(4) = 24 - 12 = 12

At t = 5, f''(5) = 30 - 12 = 18

Answer:

To find the percentage of the money collected from entry fees over the 3 days that was collected on Day 2, we need to first find the total amount collected for all three days.

Total amount collected = $750 + $400 + $300 = $1450

Then, we need to find what fraction of the total was collected on Day 2:

Amount collected on Day 2 = $400

Fraction of total collected on Day 2 = $400 / $1450

Finally, we convert the fraction to a percentage:

Fraction of total collected on Day 2 = $400 / $1450 = 0.2759

Percentage of total collected on Day 2 = 0.2759 x 100% = 27.59%

Angle, when two straight lines or rays intersect at a single endpoint,  then an angle is created.

The exterior angle of a triangle equals the sum of opposite interior angles. The angle between any side of a shape and a line that extends from the next side is known as the exterior angle.

∠XYZ  = ∠YWX + ∠WXY

10x - 5   = 3x + 17 + 3x + 2

10x - 5 = 6x + 19

10x - 6x  = 24

4x  = 24

x = 6

∠WXY =  3x + 2

= 3*6 + 2

= 20°
