Answer:

So our answer in pi form is 30.25π

Step-by-step explanation:

The circumference of a circle is given by the formulas :

\(2\pi r\) or \(\pi d\)  where r is radius and d is the diameter

Since

11π = 2πr

We can solve for r to use it in the area of a circle formula:

\(\frac{11\pi }{2\pi } = r\)

r = 5.5

The area of a circle is given by the formula:

\(\pi r^{2}\) where r is the radius/.

Since we found r we can find the area:

π(5.5)² = 30.25π

So our answer in pi form is 30.25π

Answer:

As you have not specified the format in which to give the answer, I am giving three ways of writing it:

\(\sf 30.25 \pi \ units^2\)

\(\sf \dfrac{121}{4} \pi \ units^2\)

95.03 units² (nearest hundredth)

Step-by-step explanation:

Formulae

(where r is the radius)

Given:

Therefore, use the given value and the circumference equation to find the radius:

⇒ circumference = 11π

⇒ 2πr = 11π

⇒ 2r = 11

⇒ r = 5.5

Now we have found the radius, simply substitute this into the equation for area of circle:

⇒ area of a circle = πr²

                             = π5.5²

                             = 30.25π units²

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Answer:

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.

Step-by-step explanation:

Answer:

No, the slope with the equation is 1/5 and the slope of the table is 2/1  or 2

Step-by-step explanation:

Slope is the change in y over the change in x.

Equation

y = mx + b when an equation is written in the slope intercept form of a line, the m is the slope.

y = \(\frac{x}{5}\) - 3  can be writing

y = \(\frac{1}{5}\) x - 3  It is easier to see that the slope is \(\frac{1}{5}\)

Table

Look at the y's.  The are change by 2 each time.  Now, look at the x's.  They are changing by 1 each time.  So, the slope is:

\(\frac{2}{1}\) or just 2

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer:

DB = 8

Step-by-step explanation:

Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is

\(\frac{DB}{DC}\) = \(\frac{AD}{BD}\) , substitute values

\(\frac{DB}{17.8-5}\) = \(\frac{5}{BD}\)

\(\frac{DB}{12.8}\) = \(\frac{5}{BD}\) ( cross- multiply )

DB² = 64 ( take the square root of both sides )

DB = \(\sqrt{64}\) = 8

The length of segment DB is 8 units.

From the given right triangle we can deduce the following;

From the corresponding triangle rules, we can calculate the length of DB by considering the following ratios;

\(\frac{DB}{DC} = \frac{AD}{DB} \\\\DB^2 = AD\times DC\\\\DB^2 = 5 \times (17.8-5)\\\\DB^2 = 5 \times 12.8\\\\DB^2 = 64\\\\DB = \sqrt{64} \\\\DB = 8 \ units\)

Thus, the length of segment DB is 8 units.

Step-by-step explanation:

Answer:

Time = 1.27 x 10^1 minutes

Step-by-step explanation:

To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.

Given:

Speed of light = 1.12 x 10^7 miles per minute

Distance between the Sun and Mars = 1.42 x 10^8 miles

Time = Distance / Speed

Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)

Time = (1.42 / 1.12) x 10^(8 - 7) minutes

Time = 1.27 x 10^1 minutes

Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.

Here is an example of how to draw an isosceles trapezoid:

   _______

 /                 \

/_________\

In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.

An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.

Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.

Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:

Area = ((a + b) / 2) * h

Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.

PART B:

An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.

An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.

Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.

So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.

PART C:

No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.

The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.

Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.
