Yes, the given input and output values represent a function, f(x) = x²

What are functions?

In mathematics, a function is an expression, rule, or law that specifies the relationship between an independent variable x and a dependent variable y.

y and x are related in such a way that there is a distinct value of y for each value of x, and this relationship is frequently represented as y = f(x). In other words, for the same x value, there cannot be more than one value for f(x).

If we look at the table, we can see a relationship between the x (input)  and y (output) values.

The output values (y) are the squares of the corresponding input values(x).

Also, there is only one distinct value of y for each x value.

Therefore the given values represent a function, f(x) = x².

Answer: The equation for the area of the garden is x(x - 2) = 48. To find the length, we need to solve for x:

x^2 - 2x - 48 = 0

Using the quadratic formula:

x = (-(-2) ± √((-2)^2 - 4(1)(-48)))/2(1)

x = (2 ± √(4 + 192))/2

x = (2 ± √196)/2

x = (2 ± 14)/2

x = 8 or x = -6

Since the length cannot be negative, the length of the garden is 8 feet.

The mean of the measurements is 23.3 g.
The standard deviation of the measurements is 0.65 g.

The range of the measurements is 1.9 g

The percent relative standard deviation of the measurements is 2.77%.

What is the mean, range, standard deviation, percent relative standard deviation?

Mean: The mean is the average of all the measurements. To find the mean, add up all the measurements and divide by the number of measurements:

(23.4 + 23.9 + 22.6 + 24.5 + 23.0 + 23.6) / 6 = 23.3

So, the mean of the measurements is 23.3 g.

Range: The range is the difference between the largest and smallest measurements. To find the range, subtract the smallest measurement from the largest measurement:

24.5 g - 22.6 g = 1.9 g

So, the range of the measurements is 1.9 g.

Standard Deviation: The standard deviation is a measure of the spread of the data around the mean. To find the standard deviation, we first calculate the difference between each measurement and the mean, square each difference, and then average the squared differences. The square root of this average gives us the standard deviation.

(23.4 - 23.3)^2 + (23.9 - 23.3)^2 + (22.6 - 23.3)^2 + (24.5 - 23.3)^2 + (23.0 - 23.3)^2 + (23.6 - 23.3)^2 = 0.09 + 0.16 + 0.49 + 1.16 + 0.09 + 0.16 = 2.55

2.55 / 6 = 0.425

√0.425 = 0.65

So, the standard deviation of the measurements is 0.65 g.

Percent Relative Standard Deviation (RSD): The percent RSD is the standard deviation expressed as a percentage of the mean. To find the percent RSD, divide the standard deviation by the mean and multiply by 100:

0.65 g / 23.3 g * 100 = 2.77%

So, the percent relative standard deviation of the measurements is 2.77%.

Answer:

The integrating factor, u(t), for the initial value problem t* dy/dt+3y=8t with y(1)=8 is u(t) = e^(3t). The solution to this equation is y(t) = 8e^(-3t)+2te^(-3t).

Step-by-step explanation:

The integrating factor, u(t), for the given initial value problem t(dy/dt)+4y=3t with y(1)=8 is u(t) = e^(4∫t dt) = e^(2t^2).

Using this integrating factor, the solution to the initial value problem is y(t) = (3/8)te^(2t^2)+Ce^(-2t^2), where C is a constant of integration. Since y(1)=8, we can solve for C and find that C=-7/4. Therefore, the solution to the initial value problem is y(t) = (3/8)te^(2t^2)-7/4e^(-2t^2).

We are asked the solve the following differential equation, [tex]t\frac{dy}{dt}+3y=8t[/tex].  This is an ordinary, linear, first-order DE. We need it in the form [tex]\frac{dy}{dt}+P(t)y=Q(t)[/tex], where [tex]\mu(t)=e^{\int\ {P(t)} \, dt }[/tex], which is the integrating factor.

[tex]\Longrightarrow t\frac{dy}{dt}+3y=8t[/tex], multiply everything by t.

[tex]\Longrightarrow \frac{dy}{dt}+(\frac{3}{t} )y=8[/tex]

We now have the correct form for solving a linear, first-order DE.

Find [tex]\mu(t)[/tex].

[tex]\Longrightarrow \mu(t)=e^{\int\ {P(t)} \, dt } \Longrightarrow \mu(t)=e^{\int\ {\frac{3}{t} } \, dt }[/tex]

[tex]\Longrightarrow \mu(t)=e^{3\int\ {\frac{1}{t} } \, dt }\Longrightarrow \mu(t)=e^{3ln|t|} \Longrightarrow \mu(t)=e^{ln(t^3)}[/tex]

[tex]\Longrightarrow \mu(t)=t^3[/tex]

Now multiply the entire DE by [tex]\mu(t)[/tex].

[tex]\Longrightarrow t^3[\frac{dy}{dt}+(\frac{3}{t} )y=8][/tex]

[tex]\Longrightarrow (t^3)\frac{dy}{dt}+(t^3)(\frac{3}{t} )y=(t^3)8[/tex]

[tex]\Longrightarrow (t^3)\frac{dy}{dt}+(3t^2)y=(t^3)8[/tex]

Verify that the L.H.S is a product rule of [tex]t^3y[/tex].

Product rule: [tex]\frac{d}{dx}[f(x)g(x)]=f(x)g'(x)+f'(x)g(x)[/tex]

[tex]\frac{d}{dt}[t^3y]=(t^3)(\frac{dy}{dt} )+(3t^2)(y)[/tex]

It is the product rule, so we can move forward by integrating both sides of the DE.

[tex]\Longrightarrow \int\ {[t^3y]'} \, =\int\ {8t^3} \, dt[/tex]

[tex]\Longrightarrow t^3y=2t^4+C[/tex]

Now using the initial condition to find the arbitrary constant, C.

[tex]t^3y=2t^4+C ;y(1)=8[/tex]

[tex]\Longrightarrow (1)^3(8)=2(1)^4+C[/tex]

[tex]\Longrightarrow 8=2+C[/tex]

[tex]\Longrightarrow 6=C \Longrightarrow C=6[/tex]

Now we have, [tex]t^3y=2t^4+6[/tex], solve for y.

[tex]\Longrightarrow t^3y=2t^4+6[/tex]

[tex]\Longrightarrow y=2\frac{t^4}{t^3} +\frac{6}{t^3}[/tex]

[tex]\Longrightarrow y=2t +6t^{-3}[/tex]

Thus the given differential equation with the initial condition is solved, [tex]y=2t +6t^{-3}[/tex].

Zeros

Let be equal the polynomial to zero. All roots can be found by means of numerical methods:

x⁴ - 3 · x³ + 2 · x = 0

x = - 0.732 or x = 0 or x = 1 or x = 2.732

Critical values

Determine the first derivative, equal it to zero and find the roots of the expression:

4 · x³ - 9 · x² + 2 = 0

x = - 0.432 or x = 0.541 or x = 2.141

Determine the second derivative and evaluate it at each root found in previous step:

f''(x) = 12 · x² - 18 · x + 2

x = - 0.432

f''(- 0.432) = 12.015 (MINIMUM)

x = 0.541

f''(0.541) = - 4.226 (MAXIMUM)

x = 2.141

f''(2.141) = 18.469 (MINIMUM)

Finally, find the coordinates of the quartic function:

f(- 0.432) = - 0.587

f(0.541) = 0.693

f(2.141) = - 4.148

Interval behavior

Use the first derivative find the roots of the following inequalities:

In Trigonometry, an angle is a curve made up of two rods, referred to as the angle's sides, which thus converge at a center point regarded as the ball's vertex. Two rays can create an angle in the region where they are arranged. Additionally, when airplane collide, an angle is created. Dihedral angles are what they are called. An offset is a possible shape spanning two radiation or lines with an identical termination in planar geometry. The English term "angle" comes from the Latin word "angulus," which meaning "horn." The vertex is the common endpoint of the two rays, also know as the faces of the angle.

given

one angle = 40°

other angle = (11x - 18)°

in triangle sum of all angle = 180°

40° + 11x - 18 + 40  = 180

Definition of equation

An equation is the equality between two algebraic expressions connected by the equals sign in which some known data are included together with one or more unknown values, also known as unknowns.

The terms of an equation are the addends that make up the members of an equation, whereas the members of an equation are each of the expressions that appear on both sides of the equal sign.

Finding the value that satisfies an equation is what is meant by finding its solution. By converting the unknown to the answer in this manner, the equality must be true.

This case

In this case, you consider:

S= hours of work from a senior artist.

PD= Production designer labor hours.

T= hours of work from a trainee.

On the other hand, you know that Girilla Graphics charges:

For the work of its most senior graphic artists, they charge $60 per hour.

For production designer work, the hourly rate is $30.

$19 per hour for a trainee's labor.

A recent project required:

A senior artist's 34 hours of labor.

13 hours from a production designer.

35 hours from a trainee.

So, the following formula can be used to determine the project's overall labor costs:

Total labor cost= 60×34 + 35×13 + 19×35

Solving:

Total labor cost= $3,160

In summary, a mathematical statement for calculating the total labor cost is Total labor cost= 60×S + 30×PD + 19×T and the total labor cost for the recent project is $3,160.
