Two students calculated the area of a polygon in the coordinate plane using different strategies. Explain the two methods. Which method do you prefer and why?

Answer:

69.66 cm

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{4.3 cm}\underline{Circumference of a circle}\\\\ $C=\pi d$\\\\where $d$ is the diameter\end{minipage}}[/tex]

From inspection of the given diagram:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Therefore, the perimeter of the given shaded region is the sum of half the circumference of the larger circle, half the circumference of the smaller circle, and the two 5 cm ends.

[tex]\begin{aligned}\sf \implies Perimeter & = \sf \dfrac{1}{2} \pi (24) + \dfrac{1}{2} \pi (14) + 5 + 5\\& = \sf \dfrac{1}{2}(3.14)(24) + \dfrac{1}{2}(3.14)(14) +10\\& =\sf 37.68+ 21.98+10\\& =\sf 69.66\:\:cm\end{aligned}[/tex]

Therefore, the perimeter is 69.66 cm.

The perimeter of the shaded region is 12.56 times the radius of one of the semicircles.

To find the perimeter of the shaded region, we need to find the total length of all the boundaries.

The shaded region consists of two semicircles, so we can start by finding the circumference of each semicircle.

The formula for the circumference of a circle is C = 2πr.

Since we have two semicircles, we need to find the radius for each and then add the two circumferences together to get the total perimeter.

Let's say the radius of each semicircle is r.

Using the given value of π as 3.14,

the circumference of one semicircle is 2 * 3.14 * r = 6.28r.

Therefore, the total perimeter is 6.28r + 6.28r = 12.56r.

So, the perimeter of the shaded region is 12.56 times the radius of one of the semicircles.

The total number of candies in the store is 312. It is obtained by using the concept of exponent and power on the given problem.

What is an Exponent?

The number of times a quantity is multiplied by itself is referred to as an exponent or power of the given quantity. For eg: 25, where 5 is an exponent or power of 2 and 2 is called the base of exponent 5. Any quantity raised to the power 0 always returns 1 as result.

Calculation of the total number of candies in the store

(36)2 * 30

Using the properties of an exponent, we have

A number with an exponent of 0 always gives 1

(36)2 * 1

(3)6×2 * 1

312 * 1

312

Thus, the total number of candies in the store is 312.

The process of making estimates and drawing conclusions about one or more characteristics of a population through analysis of sample data drawn from the population is known as statistical inference.

Inferential statistical analysis infers attributes of a population, for instance by testing hypotheses and generating estimates. Statistical inference is the process of employing data analysis to infer properties of an underlying probability distribution. The observed data set is thought to be a sample of a broader population. Comparable to descriptive statistics is inferential statistics. The focus of descriptive statistics is exclusively on the characteristics of the observed data; it is not predicated on the idea that the data are representative of a wider population. In machine learning, the phrase "create a prediction by evaluating an already trained model" is commonly used instead of "infer." Statistical inference uses data that has been sampled from a population to make claims about that population.

Step-by-step explanation:

According to the statement 25t is the distance between the ships after t hrs.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that perhaps the area of something like the square on which side would be the hypotenuse is equivalent to the sum of something like the areas of the squares on each of the other two sides.

The Pythagorean theorem is only valid for right-angled triangles. When any two numbers are known, we can use Pythagoras' theorem to compute the unknown sides of something like the triangle. Other real-world applications of Pythagoras' theorem include engineering and architecture.

The first ship travels north at 20 kilometers an hour, while the second travels west at 15 miles per hour.

equation for the given distance between boats after t hours:

C² = a² + b²

C = √(a² + b²)

a = dist. traveled in t hrs. of the 1st ship.

b = dist. traveled in t hrs. by 2nd ship.

c = dist. between the two ships after t hrs. (d)

Using formula Distance  = speed * time (t)

d = √((20t)²+(15t)²)

d = √(625t²)

d = 25t is the distance between the ships after t hrs.

Step-by-step explanation:

The factors of the equation x2y3 - 11x2y + 6y2 - 66 can be found by taking out the common terms.

x2y3 - 11x2y + 6y2 - 66

Let us take out the common from the first two terms.

⇒ x2y(y2 - 11)------>(1)

Take out common from the last two terms.

⇒ + 6 (y2 - 11)------>(2)

Answer: 5/6

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

It will land on 1, Prob (land on 1) = 1/6

It will not land on 1, the probability will be given as:

Prob (not land on a 1) = 1 - 1/6

Prob (not land on a 1) = 5/6

Hence the probability that it will not land on a 1 is 5/6

Integers and whole numbers are similar, but integers contain negatives and whole numbers do not. Since a city cannot have a negative population count, we'd prefer whole numbers.

The perimeter of the square is 52 units.

In this question,

the points (1, -2) and (-4, 10) are adjacent vertices of a square.

We need to find the perimeter of the square

The side length of a square is the distance between given two points.

Let a be the side length of the square.

[tex]a=\sqrt{(-4-1)^2+(10-(-2)^2)}\\\\ a=\sqrt{25+144}\\\\ a=\sqrt{169}\\\\ a=13[/tex]

The side length of the square is 13 units.

so, the perimeter of a square would be,

P = 4a

P = 4 × 13

P = 52 units

Therefore, the perimeter of the square is 52 units.
