The array that has been sorted using insertion sorting 1 2 3 4 5 6 7 8 9.

A straightforward sorting algorithm called insertion sort functions like how you might arrange playing cards in your hands.

Initial Pass: 2 9 8 7 6 5 1 4 3

The array's first two members are initially compared using an insertion sort.

Since 9 is bigger than 2, they are not arranged in ascending order, and 2 is not in the proper place. So, switch 9 and 2.

Therefore, 2 is currently kept in a sorted sub-array.

Second Pass: Continue with the next two elements and compare them.

2 8 9 7 6 5 1 4 3

Here, 9 is bigger than 8, therefore both items appear to be in ascending order; as a result, there won't be any switching. Along with 8, 9 is also kept in a sorted sub-array.

Third pass: Currently, the sorted sub-array has two entries, which are 2 and 8.

Moving on to the following two components, which are 9 & 7,

2 7 8 9 6 5 1 4 3

Continue sorting similarly; the results would be 1 2 3 4 5 6 7 8 9.

(-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.

Option (D) is the correct one.

Given, a unit circle

and we have to mention the point on the unit circle that corresponds to -π.

As, the equation of a unit circle is

x² + y² = 1

now -π is represented by the left side of the x-axis

therefore to represent the given point we have to take a point on x-axis that will be at the left side of the origin and at the unit distance from the origin.

So, (-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.

Hence, (-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.

What is the Pythagorean theorem?

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Here, we

Let the east direction is denoted by x and

the north direction is denoted by y.

dx / dt = 16 miles per hour

dy / dt = 12 miles per hour

x = 4 miles

Let the distance between both the friends be s.

Time is taken by you to travel 4 miles,

time = distance / speed = 4 / 12 = 1/4 hour

Distance traveled by your friend in time t,

y = speed x time = 12 x 1/4 = 3 miles

By Using the Pythagorean theorem,

x² + y²  = s²     ..... (1)

Substitute, x = 4 mile, y = 3 mile

s²  = 16 + 9 = 25

s = 5 miles

Now, Differentiate equation (1) with respect to t, we get

2x dx/dt + 2y dy/dt = 2s ds/dt

4 (16) + 3 (12) = 5 ds/dt

ds/dt = 20 miles per hour

Hence, the distance between you and your friend is changing at a rate of 20 miles per hour.

What is area of a circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value. The area of the circle will be A = [tex]\pi r^{2}[/tex].

The area of the circle given is = 15 m²

Sector of a circle with a central angle of 5π/11 rad

The area will be (1/2) * r² * Ф

The predicted number of calories in a sandwich containing 32 grams of fat is 559.

In algebra, the slope-intercept form of a linear equation is a typical approach to express a line on a graph. A linear equation is written as y = mx + b in standard form.

The y-intercept, or place where the line crosses the y-axis, is represented by the letters b and m, respectively. The point where the lines contacts the y-axis is known as the y-intercept, and the slope is a measurement of how steep the line is. Because it explicitly displays the slope and y-intercept, this equation's form is known as the slope-intercept form.

y = mx + b

Where m is the slope, x is the value of the independent variable, and b is the y-intercept. In this case, the slope is 13 and the y-intercept is 143. So, the equation of the line of best fit is:

y = 13x + 143

To predict the number of calories in a sandwich containing 32 grams of fat, you can plug in 32 for x in the equation:

y = 13 * 32 + 143

A 5% chance exists of concluding there is a difference when there isn't at a significance level of 0.05. Lower levels of significance suggest that you need more proof before you can rule out the null hypothesis.

In statistics, the analysis of variance (ANOVA) method is used to compare the means of two groups.

In an experiment with a completely randomized design, samples are at random assigned to either a treatment group or a placebo group.

For instance, if 40 persons are chosen to evaluate the effects of an analgesic,

four groups—Groups A, B, C, and D—could be created. Different dosages of the medication can be administered to Groups A, B, and C, while Group D receives a placebo. Due to the random grouping of the participants

, this is an illustration of a randomized design.

We assume that the sample populations are normally distributed and have the same variances in order for an ANOVA test to display completely randomized design.

Hence, A 5% chance exists of concluding there is a difference when there isn't at a significance level of 0.05. Lower levels of significance suggest that you need more proof before you can rule out the null hypothesis.

The total number of nickels and quarters with Veronica are 5 and 9, respectively.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of nickels be represented by x, while the number of quarters be represented by y.

It is known that a nickel is worth 5 cents, while a quarter is worth 25 cents. Therefore, the given statements can be written in the form of equations as,

Veronica has 4 more nickels than quarters,

x = y + 4

Coins have a combined value of 170 cents,

5x + 25y = 170

Substitute the value of x from the first equation in the second,

5x + 25y = 170

5(y + 4) + 25y = 170

5y + 20 + 25y = 170

30y = 170 - 20

30y = 150

y = 150/30

y = 5

Therefore, the number of quarters are 5.

Since, Veronica has 4 more nickels than quarters,

x = y + 4

x = 5 + 4

If a rancher has 720 feet of fencing with which to enclose two adjacent rectangular corrals, the dimensions are 90 feet and 120 feet

From the figure

4x + 3y = 720

3y = 720 - 4x

y = 240 - (4/3)x

The area = l × w

Where l is the length

w is the width

Substitute the values in the equation

A = 2x × y

= 2x (240 - (4/3)x)

Apply the distributive property

= 480x - (8/3)x^2

Differentiate the values

0 = (-16/3)x + 480

(16/3) x = 480

x = 480 / (16/3)

x = 90 feet

Then,

y = 240 - (4/3)(90)

∠R= 110°, ∠U= 70°, ∠T= 110° are the missing angle measures in parallelogram RSTU.

A parallelogram is a simple quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are of equal length, and its opposite angles are of equal measure.

Because RSTU is a parallelogram, we may use parallelogram characteristics to calculate S=U=70° ( Opposite angles of parallelogram are equal).

Using the property, sum of adjacent angles is equal to 180°, therefore,

⇒∠S+∠R= 180°

⇒70°+∠R= 180°

⇒∠R= 180°- 70°

⇒∠R=110°

Also, ∠R= ∠T= 110° (Opposite angles of parallelogram are equal).

Thus, ∠R=110°, ∠T= 110° and ∠U=70°

In the given question, the absolute percentage increase is 1050 and the relative percentage increase is 32.3076%.

When you want to analyze how a value has evolved over time, a percentage increase is helpful.

Although percentage increase and absolute increase are fairly comparable, the former is more helpful when contrasting different data sets.

For instance, a change from 1 to 51 and a change from 50 to 100 both have an absolute change of 50, but the first change grew significantly more due to the higher percentage growth of 5000% compared to the second change of 100%.

The most popular method of assessing growth is percentage increase because of this.

So, the absolute and relative percentage increase is:

The town's population grew from 3,250 in 2008 to 4,300 in 2010.

2008: P1 = 3250

2010: P2 = 4330

Absolute variation:

Absolute difference = P2 - P1

Absolute difference = 4330 - 3250

Absolute difference = 1050

Relative increase:

Relative percentage = P2 - P1/P1 * 100

Relative percentage = 1050/3250 * 100

Relative percentage = 32.3076
