A square is inscribed in a circle. Write the area of the square as a function of the radius.

Answers

Answer 1

Area will be 2[tex]r^{2}[/tex]

What is area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form.

Given radius of circle is r

Then area of circle=π[tex]r^{2}[/tex]

The diagonal of the square is comparable to the diameter (2r) of the circle since two opposing corners of the square contact it.

Now, we will set up Pythagoras' Theorem to determine one side of the square:

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

Since it is a square a=b which means all  the sides are same

∴2[tex]a^{2}[/tex] = [tex]c^{2}[/tex]

We know c, which is 2r, the diagonal.

∴2[tex]a^{2}[/tex] = [tex](2r)^{2}[/tex]

⇒[tex]a^{2}[/tex] = 2[tex]r^{2}[/tex]

We can leave it as [tex]a^{2}[/tex]

since a is one side of the square and [tex]a^{2}[/tex] would be the area of the square.

So the area of the square =2[tex]r^{2}[/tex]

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In the figure,

The value of angle a and e are;

⇒ a = 115°

⇒ e = 69°

Now,

Since, There are two parallel lines shown in figure.

Hence, We know by the definition of alternate angles of parallel lines,

⇒ ∠a = ∠f + ∠e

Here, We have to given that;

The angles are,

⇒ a = 115°

⇒ e = 69°

So, We get by substitute the value of angle a and e;

⇒ ∠a = ∠f + ∠e

⇒ 115° = ∠f + 69°

Subtract 69° both side, we get;

The 3rd term in a geometric sequence is -18 and the 6th term is 9216.
Find the a) common ratio, b) the first term a1, and c) the 4th term a4 in this geometric sequence.

Answers

Answer: The common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.

Step-by-step explanation: The common ratio r of a geometric sequence is found by dividing the second term by the first term, and the nth term of the geometric sequence is given by a1 * r^(n-1), where a1 is the first term.

To find the common ratio r of this geometric sequence, we can use the fact that the 3rd term is -18 and the 6th term is 9216:

-18 = a1 * r^2

9216 = a1 * r^5

Dividing these two equations, we get:

-18/9216 = (a1 * r^2) / (a1 * r^5)

-18/9216 = r^-3

r = (-18/9216)^(-1/3)

Since r is the common ratio, it must be positive. Since (-18/9216)^(-1/3) is negative, we must take the positive root:

r = ((-18/9216)^(-1/3))^(1/3)

r = ((-18/9216)^(1/9))

r = (9216/-18)^(1/9)

r = (-512)^(1/9)

r = (-8)^(1/9)

r = (-2)^(2/9)

r = (-2)^(2/3)

r = (1/4)^(2/3)

r = 1/2

To find the first term a1, we can use the fact that the 3rd term is -18 and the common ratio is 1/2:

-18 = a1 * (1/2)^2

-18 = a1/4

a1 = -72

To find the 4th term a4, we can use the fact that the first term is -72 and the common ratio is 1/2:

a4 = (-72) * (1/2)^3

a4 = -9

Therefore, the common ratio of the geometric sequence is 1/2, the first term is -72, and the 4th term is -9.

How to convert polar coordinates into cartesian coordinates?

The cartesian coordinates for the polar coordinates are calculated by the formulae,

x = rcosθ, and y = rsinθ

Where the polar coordinates are (r, θ).

Calculation:

The cartesian coordinates for the given polar coordinates are as follows:

(A) (r, θ) = (2, π)

Then,

x = r cosθ = 2 cos(π) = 2(-1) = -2

y =r sinθ = 2 sin(π) = 2(0) = 0

Therefore, the cartesian coordiantes are (X, Y) = (-2, 0).

You are selling tickets at a dance. Individual tickets cost $6, and 2 tickets for a couple cost $10. After the dance, you count $1075 and 195 tickets.

let

x = number of individual ticket

y = number of couple tickets = 2x

Therefore, using equation,

2x(10) + 6x = 1075

2x + x = 195

Hence,

20x + 6x  = 1075

3x = 195

x = 195 / 3

x = 65

Hence,

26x = 1075

26(65) = 1690

A total of 420 tickets were sold for the school play they were either adult tickets or student tickets the number of student tickets sold was three times the number of adult tickets sold how many adult tickets were sold

Answers

Answer: I believe 140

Step-by-step explanation: This is how I found my answer:

420 / 3

= 140

420-140

=  280

420= number of all tickets sold.

140= number of adult tickets sold

280= number of student tickets sold

You might wonder how I know why it's 140. I know it's 140, because using my context clues, it stated:

"the number of student tickets sold was three times the number of adult tickets."

So, the one that was the bigger amount must be the student's tickets sold, while the lower amount has to be the adult's tickets sold. I hope this helped!

Answer:

83

Step-by-step explanation:

(78+72+87+90+x)/5=82

327+x=82*5

327+x=410

x=410-327

x=83

Answers

The real and complex solutions of the polynomial equation [tex]x^{3} - 8[/tex] = 0 is 2,  -1 + [tex]\sqrt{3}[/tex]i  and  -1 - [tex]\sqrt{3}[/tex]i. option 2 is correct.

Polynomial equation: what is it?

Polynomial equations are those created using exponents, coefficients, and variables. The greater of its possible exponents is referred to as the equation's degree. By factoring polynomials according to their degree and the variables in the equation, we may find their solutions.

Our equation is [tex]x^{3} - 8[/tex]

and we know that:  [tex]x^{3} = 8[/tex]

then we can write our equation as: [tex]x^{3} - 2^{3}[/tex]

And using the identity: [tex]a^{3} - b^{3} = (a-b) *(a^{2} +ab+b^{2} )[/tex]

where a = x and b = 2, then our equation is:

them, if x = 2 the first part is zero, so x = 2 is a solution, and now we need to see the second part in order to find the complex solutions.

[tex]x^{2} + 2x +2^{2}[/tex] = 0

Here we need to use.

a[tex]x^{2}[/tex] + bx + c = 0 if  for a, b and c constants, then:

x = [tex]-b +-\sqrt{b^{2} - 4ac } /2a[/tex]

in our problem we have:

x = -2 +-[tex]\sqrt{4 - 16}[/tex] /2

x = -1 +-[tex]\sqrt{-3}[/tex]

x =  -1 +-[tex]\sqrt{3}[/tex] i

So here we have two complex solutions:  -1 + [tex]\sqrt{3}[/tex]i  and  -1 - [tex]\sqrt{3}[/tex]i

So the value of x are 2,  -1 + [tex]\sqrt{3}[/tex]i  and  -1 - [tex]\sqrt{3}[/tex]i

I think you mean

What are the real and complex solutions of the polynomial equation? (1 point)

[tex]x^{3} - 8[/tex] = 0

( the equation is [tex]x^{3} - 8[/tex] = 0 and not x-8 =0)

in the chi-square test of independence, large values of the chi-square test statistic indicate a cause/effect relationship between the two categorical variables.
true
false

Answers

The given statement " in the chi-square test of independence, large values of the chi-square test statistic indicate a cause/effect relationship between the two categorical variables. " is false.

In math chi square test means the process of determine if there is a significant relationship between two nominal (categorical) variables.

Here we have the statement, in the chi-square test of independence, large values of the chi-square test statistic indicate a cause/effect relationship between the two categorical variables.

And we need to find the statement is true or not.

According to the definition of chi square test, we know that it checks whether two variables are likely to be related or not.

Here we have counts for two categorical or nominal variables.

So, there is no large value comparision take palce.

Therefore, the statement is false.
