According to the volume of the box, the height of the box is (2x + 3)

Volume:

Volume is defied as the space occupied within the boundaries of an object in three-dimensional space.

Given,

In order to package products for her business class, Jessica needs to determine the size of a box in which they would fit. To meet shipping specifications, the volume of the box should be 6x² - 15x-36. The box is in the shape of a rectangular prism. The width of the box must be 3, and the length of the box must be x - 4.

Now, we have to find the expression or the height of the box.

From the given details, we know that,

Volume of the box = 6x² - 15x-36

Width of the box = 3

length of the box = x - 4

Let us consider the height of the box is h.

By using the volume of the box formula, we have calculated the height of the box as,

=> 6x² - 15x-36 = (3) × (x-4) × h

Here we need the value of h,

The given expression is rewritten as,

=> (6x² + 15x-36) / 3(x - 4) = h

When we factorize the numerator, then we get,

=> 3(2x + 3)(x - 4)/3(x-4) = h

Therefore, the expression for h is 2x + 3.

YES, the absolute value of an integral is always less than the integral of the absolute value for Lebesgue integrals.

An integral is like a sum, but fancier. So look at a sum 1+(-5)+2+(-3)=-5. Take the absolute value, |1+(-5)+2+(-3)|=5. But, if you take the absolute value of the individual terms and then add them, you get |1|+|-5|+|2|+|-3|=1+5+2+3=11. 11>5

The reason is that when you add them all up and then take the absolute value, the positive and negative terms of the sum get to cancel each other out and make the absolute value of the sum greater overall. When you take the absolute value of individual terms, you force them all to "point in the same direction" (positive) so they are working together and the sum gets higher.

The correct answer is 7XS when RR' = 14, then RZ = 7 when the parallelogram PQRS is reflected across the line of reflection.

Given that,

If RR' = 14, then RZ = 7 when the parallelogram PQRS is reflected across the line of reflection.

SX = 5 if Y = 5.

In Euclidean geometry, a parallelogram is a straightforward (non-self-intersecting) quadrilateral with two sets of parallel sides.

A parallelogram has equal-length opposing angles and facing or opposing sides.

The Euclidean parallel postulate or one of its equivalent formulations must be used in order to demonstrate the congruence of opposite sides and angles because both requirements flow naturally from this postulate.

A quadrilateral with only one pair of parallel sides, on the other hand, is referred to in British or American English as a trapezoid or trapezium.

We get,

The parallelepiped is a three-dimensional representation of a parallelogram.

It will cost $776.25 to paint the area of the rectangular wall

The area can be defined as the amount of space covered by a flat surface of a particular shape. It is measured in terms of the "number of" square units (square centimeters, square inches, square feet, etc.) The area of a rectangle is the number of unit squares that can fit into a rectangle. Some examples of rectangular shapes are the flat surfaces of laptop monitors, blackboards, painting canvas, etc.

The formula of area of a rectangle is given as;

A = L * W

Imputing the values and calculate the area of the rectangular wall;

A = 12.5 * 18

A = 225ft²

But in the question, the cost of painting the wall is $3.45 per square feet.

1ft² = 3.45

225 = x

x = 3.45 * 225

x = 776.25

The length of SR will be 15 units, using Pythagoras' theorem

What is Pythagoras' theorem?

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Remember that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Triangle SRT and triangle TRQ can be compared using the image. Since both triangles have equal sides and right angles (T), they are both triangles (RT)

Using Pythagoras theorem,  

RQ² = TQ² + TR²

20² = TR² + 16²

TR = 12

SR/RQ = TR/TQ

SR / 20 = 12 / 16

SR = 15 units

Hope this helps.

The inverse of the functions are f⁻¹(x) = 2/[3(x + 4)], f⁻¹(x) = √[(x + 1)/2] and f⁻¹(x) = 1/x + 1

Function (a)

This function is given as

f(x)=2/(3x) - 4

The function needs to be represented as an equation

So, we have

y = 2/(3x) - 4

Swap the positions of x and y

x = 2/(3y) - 4

So, we have

2/(3y) = x + 4

Take the reciprocal of both sides

3y/2 = 1/(x + 4)

Multiply both sides by 2/3

y = 2/[3(x + 4)]

So, the inverse function is

f⁻¹(x) = 2/[3(x + 4)]

The inverse is a function with the domain x ≠ -4 and range of f(x) ≠ 0

See attachment 1 for the graphs

Function (b)

This function is given as

f(x) = 2x² - 1

The function needs to be represented as an equation

So, we have

y = 2x²- 1

Swap the positions of x and y

x = 2y² - 1

So, we have

2y²= x + 1

Divide both sides by 2

y²= 1/2(x + 1)

Take the square roots

y= √[(x + 1)/2]

So, the inverse function is

f⁻¹(x) = √[(x + 1)/2]

The inverse is a function with the domain x ≥ -1 and range of f(x) ≥ 0

See attachment 2 for the graphs

Function (c)

This function is given as

f(x) = 1/(x - 1)

The function needs to be represented as an equation

So, we have

y = 1/(x - 1)

Swap the positions of r and y

x = 1/(y - 1)

So, we have

y - 1 = 1/x

Add 1 to both sides

y = 1/x + 1

So, the inverse function is

f⁻¹(x) = 1/x + 1

The inverse is a function with the domain x ≠ 0 and range of f(x) ≠ 1

Total force exerted is 50N.

What is force?

Force is any interaction that, when unopposed, will change the motion of an object.

Main body:

F=Mg-Ma

then implied:

a=(F-Mg)/M

which seems unsound, it should have said:

a = (Mg - F)/M

----------------------

Now, let's begin and use the previous gentleman's notation:

Mass of bucket=M

mass of cylinder=m

Tension force=F

So, regarding the bucket:

F + Ma = Mg

F = Mg - Ma

a = (Mg - F)/M

Also, regarding the cylinder: T = Iα

∴ (By the dot product of torque, radial vector crossed with force, r cross F, which is Frsinθ for θ = 90 degrees)

T = Iα = Fr = (1/2)(mr2)(a/r)

where α = a/r

And T = Fr because that's what torque is, just the radial distance times the force.

So

a = 2F/m

and we also have:

a = (Mg-F)/M

So 2F/m = (Mg-F)/M

2F = mg - mF/M

2F+(mF)/M = mg

F(2+m/M) = mg

F = mg/(2+m/M)

F = (127.4 )/(2+0.56)

F = 49.765 N

That is to say, the tension that the rope induces on the bucket is 50.5 Newtons in the upward direction (positive).

Hence force exerted is approx 50 N.

It is a measure of the ability to differentiate between information-bearing patterns and random patterns that distract from the information.

About 50 percent of its former width.

Now, According to the question:

Let's assume that our parameter of interest is given by θ and in order to construct a confidence interval we can use the following formula:

θ = ± ME(θ vector)

Where θ vector is an estimator for the parameter of interest and the margin of error is defined usually if the distribution for the parameter is normal as:

ME = [tex]z_\alpha[/tex]SE

Where [tex]z_\alpha /2[/tex]  is a quantile from the normal standard distribution that accumulates [tex]\alpha /2[/tex] of the area on each tail of the distribution. And SE represent the standard error for the parameter.

If our parameter of interest is the population proportion the standard of error is given by:

SE =[tex]\frac{p(1-p)}{n}[/tex]

And if our parameter of interest is the sample mean the standard error is given by:

SE = [tex]\frac{1}{\sqrt{n} }[/tex]

As we can see the standard error for both cases assuming that the other things remain the same are function of n the sample size and we can write this as:

SE = f(n)

And since the margin of error is a multiple of the standard error we have that

ME = f(n)

Now if we find the width for a confidence interval we got this:

Width = θ + ME (θ) - [θ - ME (θ)]

Width = 2ME(θ)

And we can express this as:

Width = 2f(n)

And we can define the function f(n) = [tex]\frac{1}{\sqrt{n} }[/tex]  since as we can see the margin of error and the standard error are function of the inverse square root of n. So then we have this:

[tex]Width_i[/tex] = [tex]2\frac{1}{\sqrt{n} }[/tex]

The subscript i is in order to say that is with the sample size n

If we increase the sample size from n to 4n now our width is:

[tex]Width_f[/tex] = [tex]2\frac{1}{\sqrt{4n} }[/tex] = [tex]2\frac{1}{\sqrt{n}\sqrt{4} }[/tex] = [tex]\frac{1}{\sqrt{n} }[/tex] = 1/2 [tex]Width_i[/tex]

The subscript f is in order to say that is the width for the sample size 4n.

So then as we can see the width for the sample size of 4n is the half of the with for the width obtained with the sample size of n. So then the best option for this case is:
