The sentence written in the passive voice is - The delicious bread is baked by Mr. Jilin

This sentence is written in the passive voice because it follows the passive voice structure of: Object + Past Participle Verb (baked) + by Agent (Mr. Jilin).

In the passive voice, the object of the sentence (delicious bread) is the focus of the sentence, rather than the agent (Mr. Jilin).

Passive voice is a grammatical construction in which the subject of a sentence is not the one performing the action.

Instead, the action is done to the subject. For example, instead of saying "I ate the apple," one might say "The apple was eaten by me."

In passive voice, the subject of the sentence is often omitted and the verb is usually conjugated with a form of "to be" and the past participle of the verb.

This grammatical construction is used to emphasize the object of the action, rather than the subject, and can also be used when the subject is unknown or unimportant.

Passive voice can also be used in scientific and technical writing to create sentences that are clear and concise.

Note that according to the areas of the circles in square units, the circles ordered from the least to the greatest is:

To determine the correct order, we need to solve for the areas of all the circles given the various factors provided.

A) a circle with an area of 1,040.09 square units. (Area given)

B) a circle with a radius of 27 units

Area where radius is given is computed using:

A = πr²

A = π * 27²

A [tex]\approx[/tex] 2290.22

C) a circle with a circumference of 87.92 units

Since Circumference is given:

A = C²/4π

Where C = Circumference

Thus A = 87.92²/*4*π)

A [tex]\approx[/tex] 615.13

D) a circle with a diameter of 19 units.

Area, where the diameter is given, is:
A = 1/4 πd²

A = 1/4 * π * 19²

A [tex]\approx[/tex] 283.53

Thus, it is correct to state that the order of the Areas of the Circles given from least to greatest is:

The mistake which Dennis made include the following: B. he didn't exclude x = 3, which makes the denominator in the original expression equal to zero.

In Mathematics, a rational expression simply refers to a type of expression  which is expressed as a fraction. This ultimately implies that, a rational expression is composed of two (2) main parts and these include the following:

Generally speaking, the excluded values of any rational expression simply refers to the values for which the expression is undefined, which is typically obtained when the denominator is equal to zero (0).

Rational expression = (x² - 6x + 0)/(x² + x - 12)

When x = 3, we have the following expression:

Rational expression = (x² - 6x + 0)/(3² + 3 - 12)

Rational expression = (x² - 6x + 0)/(9 + 3 - 12)

Rational expression = (x² - 6x + 0)/0

Rational expression = undefined.

Therefore, excluded values are x ≠ 3 and 4.

What is the Principle of Inclusion-Exclusion?

The Principle of Inclusion-Exclusion is a combinatorial principle used to find the number of elements in the union of two or more finite sets. It states that the total number of elements in the union of two sets is equal to the sum of the number of elements in each set minus the number of elements in their intersection.

To find the total number of young girls, we can use the Principle of Inclusion-Exclusion. This principle states that if A and B are two events, then the number of elements in the union of A and B is equal to the sum of the number of elements in A and B, minus the number of elements in their intersection.

In this problem, let's call the number of young girls who like sour taste only "A", the number of young girls who like chilly taste only "B", and the number of young girls who like both tastes "C". Then, the total number of young girls is equal to the number of girls in A, plus the number of girls in B, minus the number of girls in C.

Since one fourth of the girls like sour taste only, the number of girls in A is 1/4 of the total number of girls. Similarly, since one third of the girls like chilly taste only, the number of girls in B is 1/3 of the total number of girls. And since 50 of the girls do not like both tastes, the number of girls in C is 50.

So, the total number of young girls is equal to (1/4) * total + (1/3) * total - 50. We can solve for the total by rearranging the equation and using the given information:

total = (50 + (1/4) * total + (1/3) * total) / (1 - (1/4) - (1/3))

total = (50 + 3/12 * total) / (5/12)

total = (50 * 12/5) / (7/5)

total = 120

Therefore, there are 120 young girls in the survey.

The volume of the drinking glass in cubic centimeters is 442.4189 cm^3 .

The cylinder is a three-dimensional shape having a circular base.

A cylinder can be seen as a set of circular disks that are stacked on one another.

The volume of a three-dimensional shape is equal to the amount of space occupied by that shape.

Now, think of a scenario where we need to calculate the amount of sugar that can be accommodated in a cylindrical box.

For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base times the height.

Therefore, the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder

Since the  base is the circle, it can be written as

Volume =  πr^2 × h

Therefore, the volume of a cylinder = πr^2h cubic units.

By inspection of the graph we can say that the first two hours the position of the motorcycle steadily moves away from the house. Then for the duration of 1 hour(hour2-hour3) the motorcycle moves closer to the house. Finally the motorcycle's position for an hour does not change meaning that the motorcyle has not moved for the duration of another hour.

So the motorcycle moves away from the house for two hours. Then it moves back towards the house for an hour. Finally it parks for an hour. This corresponds to the first answer choice.

The values of a that make |a| = 0 are the roots of the cubic polynomial equation -6a^3 + 27a^2 + 81 = 0.

What is polynomial ?

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

To find the values of a that make the determinant of the matrix |a| equal to 0, we need to evaluate the determinant of the matrix:

|a| = a * (-6a + 9) - (3a^2 - 9) * 9

= -6a^3 + 27a^2 + 9a * 9 = 0

We can then solve for a using polynomial roots:

-6a^3 + 27a^2 + 81 = 0

The values of a that make |a| = 0 are the roots of the cubic polynomial equation -6a^3 + 27a^2 + 81 = 0.

(a) The work done in pulling the rope to the top of the building is approximately 4800 ft-lb.

(b) The work done in pulling half the rope to the top of the building is approximately 2400 ft-lb.

The work done in pulling the rope to the top of the building can be calculated using a Riemann sum:

Where Δx is a small change in the length of the rope, g is the acceleration due to gravity (32 [tex]ft/s^2[/tex]), and the sum is taken over the entire length of the rope (from 0 to 100 ft).

Expressing the work as an integral, we have:

W=∫ [tex]0^{100} (0.8 lb/ft) x (g) x (x) dx[/tex]

Evaluating this integral gives us the work done in pulling the rope to the top of the building:

[tex]W = (0.8 lb/ft) x (g) x (x^2/2)[/tex] evaluated from x=0 to x=100

W = 4800 ft-lb

(b)To find the work done in pulling half the rope to the top of the building, we simply evaluate the integral from x=0 to x=50 (the length of half the rope).

Answer:

Below

Step-by-step explanation:

Company 1 charges 9.25 for 2.5 pounds and 14.50 for 6 pounds

      so  (6-2.5) pounds costs (14.50 - 9.25)

                3.5 pounds cost an increase of 5.25  

                       5.25 dollars / 3.5 pounds = 1.50 per pound

Company 2 's rate is the slope of the line =   (7.25-6.50)/ 1 = .75 dollar per pound   ( found by looking at the cost of 1 pound and the cost of 2 pounds)

Fixed cost for company 2 is the value where x = 0......the y-axis intercept = $ 5.75

Answer:

Step-by-step explanation:

Company 1:  find constant rate =  Δy/Δx, from any two (x,y) pairs on the data table

Constant rate = (14.50 - 9.25) / (9.25 - 2.5) = 1.5

Company 2 constant rate = $1.50/lb

Find the fixed fee for Company 1 by finding the y-intercept.

y - y1 = m(x - x1)     Choose any (x,y) from the data table

y - 9.25 = 1.50(x - 2.5)     Now put the equation in slope-intercept form.

y = 1.50x - 3.75 + 9.25

y = 1.50x + 5.50

Company 1 fixed fee = $5.50

Company 2:  find the slope of the line to get the constant rate, pick any 2 points on the line.

m = Δy/Δx = (7.25 - 5.75) /(2 - 0) = 0.75

Company 2 constant rate = $0.75/lb

Find the fixed fee by finding the y-intercept on the graph (where the line intersects the y axis at x = 0)

Company 2 fixed fee = $5.75

The tip of the second hand of the clock moves a distance as far as 5.2 inches in 10 seconds.

The distance traveled by the tip of the second hand on a clock can be calculated by using the formula for circumference of a circle, which is:

C = 2πr

where C is the circumference, π is approximately equal to 3.14159, and r is the radius.

If the length of the second hand is 5 inches, then the radius of the circle is 5 inches.

Therefore, the circumference of the circle traced by the tip of the second hand is C = 2πr = 2π(5 inches) = 10π = 31.4159

If we assume that the second hand moves at a constant speed, then the distance traveled by the tip in 10 seconds is equal to the circumference of the circle multiplied by the fraction of the circumference covered in 10 seconds.

Since the second hand completes one full revolution in 60 seconds, then in 10 seconds it covers 1/6 of the circumference. Therefore, the distance traveled by the tip in 10 seconds is:

1/6 C = 1/6(31.4159 inches) = 5.23598 inches

On solving the provided question, we can say that the inequality equation is swim ≥ 100 yards, tread ≥ 5 min and under ≥ 10 yards

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

the inequality equation is

swim ≥ 100 yards
