I’m circle R with m angle QRS=82 and QR=16 units find the of arc length of QS. Round to the nearest hundredth

Answer: The radius of the circle is 7.75 m (approximately)

Step-by-step explanation: The area of a sector is determined as follows;

Area of sector = (∅/360) x πr²

The area has been given as 10π, and the angle subtended by the sector has been given as 60. Substituting for known values we now have;

10π = (60/360) x πr²

10π = (1/6) x πr²

By cross multiplication we now have;

(10π/π) x 6 = r²

10 x 6 = r²

60 = r²

Add the square root sign to both sides of the equation

√60 = √r²

7.7459 = r

The radius of the circle is approximately 7.75 meters

To prove the converse of the Pythagorean theorem, it must be assumed that the Pythagorean theorem is true. This assumption is fundamental to the proof. Option A is correct answer.

The proof of the converse of the Pythagorean theorem.

To prove the converse of the Pythagorean theorem, it is important to start by assuming that the Pythagorean theorem itself holds true.

Therefore, option A is the correct answer: It must be assumed that the Pythagorean theorem is true.

This fundamental assumption is crucial since the converse states that if the sum of the squares of two sides of a triangle is equal to the square of the third side, then the triangle is a right triangle.

This is a direct implication assuming the Pythagorean theorem's validity.

An essential part of a mathematical proof, especially in geometry, involves using established theorems and logical deductions.

It's also worth mentioning Euclid's proposition that states, "Any two sides of a triangle are together greater than the third side." While this proposition is relevant to the properties of triangles, it is not a component of the proof for the converse of the Pythagorean theorem.

Segment AC is twice as long as segment A''C''.

The relationship between segment AC and segment A''C'' is that segment AC is a dilation of segment A''C'' by a scale factor of 2 from the origin. This means that segment AC is twice as long as segment A''C''.

Answer:

y = - [tex]\frac{1}{4}[/tex] x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line

m = [tex]\frac{-4+3}{4-0}[/tex] = - [tex]\frac{1}{4}[/tex]

Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = - [tex]\frac{1}{4}[/tex] x - 3 ← equation of line

The first thing is to define each one:

Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.

Example:

This is a:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

The degree of this polynomial is 3 because it is the largest exponent.

Linear term coefficient: is the number that multiplies the variable with the highest exponent

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 5 because [tex]x^{3}[/tex] is the variable with the highest exponent

Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.

Example:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 20 because it is the one found without multiplying any linear term (x)

Answer: C. 10 cm

Step-by-step explanation:

the hypotenuse of a right triangle will always be longer than the other 2 sides.  So 10 cm

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 8 cm

b = 6 cm

c = x

^^^Plug these numbers into the theorem

[tex]8^{2} +6^{2} =x^{2}[/tex]

simplify

64 + 36 = [tex]x^{2}[/tex]

100 = [tex]x^{2}[/tex]

To remove the square from x take the square root of both sides to get you...

√100 = x  

Which is when simplified:

(choice C)

10 cm

P(t)= 40*1.9^t/3

A function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) =[tex]40 + 12t[/tex] (in t weeks).

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The number of people who received letters three weeks later:

= [tex]40 + \frac{9}{10} \times40[/tex]

= [tex]76[/tex]

The number of people who received letters one week later:

= [tex]40+(\frac{9}{10} \div3)\times40[/tex]

= [tex]52[/tex]

The number of people who received letters t week later:

= [tex]40+(\frac{9}{10} \div3).t\times40[/tex]

= [tex]40 + 12t[/tex]

So, a function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) = [tex]40 + 12t[/tex] (in t weeks).

The length of the radius, r, is 21 cm. The correct answer is **c. 21 cm**.

Here's why:

- The circumference of a circle is calculated by the formula C = 2πr, where C is the circumference and r is the radius.

- We are given that the circumference of circle O is 42π.

Substituting the given value into the formula:

42π = 2πr

Dividing both sides by 2π:

r = 42π / 2π

Simplifying:

r = 21

Therefore, the length of the radius, r, is 21 cm.

Options a, b, and d are incorrect because they either involve taking the square root of the circumference directly (invalid formula for radius) or miscalculating the result of the division.

With the second question, the point must be the same distance from Q as P is already.  That's 3 lines over and 7 lines up and down.  It could stay at (__,9), so 3 spaces over is (13,9).

Answer:

undefined.  

Step-by-step explanation:

so there is a point at the origin, and from there there are two rays coming off it.  One goes along the positive x axis, so it goes straight right, then the other goes through point (0,1).  That point is right above the origin.  So it makes an l shape.  what sort of polygon could you fit into the corner of an L?  Well, a square or rectangle, and the corners of a square and rectangle are all 90 degrees is theta.

Now it wants tan of 90 degrees.  tangent is sine divided by cosine, so let's find those.

sine of 90 is the y value on the unit circle at 90 degrees.  Since the unit circle has a radius of 1 then when it points straight up or down the y value is either 1 or -1 respectively.  Similarly cosine is 1 when pointing to the right, at 0 degrees or 360 degrees, and -1 at 180 degrees.  For sine straight up is of course 90 degrees and down is 270 degrees.

Now, sine of 90 is 1 and cosine of 90 is therefore 0.  so now we want sine divided by cosine.  this is 1/0.  Well you can't divide by 0, so it is undefined.
