What is meant by cyclic quadrilateral?

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also sometimes called inscribed quadrilateral. The circle which consists of all the vertices of any polygon on its circumference is known as the circumcircle or circumscribed circle.

A cyclic quadrilateral means a quadrilateral that is inscribed in a circle. That means there is a circle that passes through all four vertices of the quadrilateral. The vertices are said to be concyclic. The center of the circle is known as the circumcenter and the radius of the circle is known as the circumradius. In the figure given below, ABCD is a cyclic quadrilateral with a, b, c, and d as the side-lengths and p and q as the diagonals.

Step-by-step explanation:

[tex]f(-x)=-x^3+\frac{7}{x}[/tex]

[tex]-f(x)=-x^3+\frac{7}{x}[/tex]

To find [tex]f(-x)[/tex], you have to plug [tex]-x[/tex] into the function for [tex]x[/tex].

To find [tex]-f(x)[/tex], you have to multiply the entire function by [tex]-1[/tex].

Since both functions are the same, by the property of odd functions ([tex]f(-x)=-f(x)[/tex]), the function is odd.

The graph of the function are attached

f(x) = 3x^2 - 4 (opens upward)

f(c) = -3x^2 + 1 (shifts 5 units upward)

f(c) = -3(x + 5)^2 - 4 (shifts 5 units to the left)

The quadratic equation required is f(x) = - 3x^2 - 4

For the graph to open upward change the sign opposite 3x^2 hence we have

f(x) = 3x^2 - 4 (graph attached)

The quadratic function f(c) = -3x^2 - 4 to shift up add some a number say 5 to it or down (subtract a number from it)

f(c) = -3x^2 - 4 + 5

f(c) = -3x^2 + 1 (graph attached)

to shift the graph left or right add or subtract a number say  to the x as below

f(c) = -3(x + 5)^2 - 4 (shifts to the left 5 units graph attached)

The number of ways car 2 or more tires can be selected out of 8 tires is 247 ways

To select 2 or more tires out of 8 tires, we can use the concept of combinations.

The total number of ways to select r items out of n items is given by the formula:

nCr = n! / (r! * (n-r)!)

where n is the total number of items, and r is the number of items to be selected.

For selecting 2 or more tires out of 8 tires, we can find the total number of ways to select 2 tires, 3 tires, 4 tires, 5 tires, 6 tires, 7 tires, and 8 tires, and then add them together.

Adding all the above results, we get:

28 + 56 + 70 + 56 + 28 + 8 + 1 = 247

the correct answer to the given question about car loan is option D: $2,315.38; $383.22.

To determine the interest and monthly payment for the car loan, we can use the add-on interest formula:

Total Interest = Principal x Rate x Time

where:

Principal = $16,079 (the amount of the loan)

Rate = 3.6% (the add-on interest rate)

Time = 4 years

Total Interest = $16,079 x 0.036 x 4

Total Interest = $2,315.38

So the total amount of interest on the loan is $2,315.38.

To calculate the monthly payment, we can use the following formula:

Monthly Payment = (Principal + Total Interest) / (Number of Payments)

where:

Principal = $16,079 (the amount of the loan)

Total Interest = $2,315.38 (the total interest on the loan)

Number of Payments = 4 x 12 = 48 (since the loan is for 4 years, and there are 12 months in a year)

Monthly Payment = ($16,079 + $2,315.38) / 48

Monthly Payment = $383.22

Therefore, the amount of interest on the loan is $2,315.38 and the monthly payment for the car loan is $383.22.

What is null hypothesis's?

A null hypothesis is a statement or assumption that there is no significant difference or relationship between two or more variables or groups. In statistical hypothesis testing, the null hypothesis is usually denoted as H0 and is tested against an alternative hypothesis (Ha), which is the hypothesis that there is a significant difference or relationship between the variables or groups being studied.

According to the question:
(a) The null hypothesis is that there is no significant difference in the average amount of money spent per day between the two groups. The alternative hypothesis is that there is a significant difference in the average amount of money spent per day between the two groups.

Since we are not given any information about the direction of the difference, we will use a two-tailed test. The appropriate test to use in this situation is the two-sample t-test.

(b) To find the critical z-value, we first need to calculate the degrees of freedom for the test:

df = (n1 + n2 - 2) = (25 + 27 - 2) = 50

Using a significance level of 0.01, we find the critical z-value using a z-table or calculator:

Critical z-value = ±2.576

(c) To find the test value, we will first calculate the pooled standard deviation using the formula:

[tex]sp = \sqrt{((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2)}[/tex]

where s1 and s2 are the sample standard deviations and n1 and n2 are the sample sizes. Substituting the given values, we get:

[tex]sp = \sqrt{((24 * 5.3^2) + (26 * 6.8^2)) / 50} = 6.083[/tex]

Next, we calculate the t-value using the formula:

[tex]t = (x1 - x2) / (sp * \sqrt{1/n1 + 1/n2})[/tex]

where x1 and x2 are the sample means. Substituting the given values, we get:

[tex]t = (38.6 - 37.4) / (6.083 * \sqrt{1/25 + 1/27}) = 1.213[/tex]

Since the absolute value of the test value is less than the critical z-value, we fail to reject the null hypothesis. Therefore, we cannot conclude that there is a significant difference in the average amount of money spent per day between the two groups.

Answer: We can simplify the expression using trigonometric identities:

tan a + sec a - 1 - (tan a - sec a + 1) / (1 + sin a cos a)

= tan a + sec a - 1 - (tan a - sec a + 1) / cos^2 a

= (sin a / cos a + 1 / cos a - cos a / cos a) - [(sin a / cos a - 1 / cos a - cos a / cos a) / cos^2 a]

= (sin a + 1 - cos a) / cos a - [(sin a - 1 - cos^2 a) / cos^3 a]

= [(sin a + 1 - cos a) cos^2 a - (sin a - 1 - cos^2 a)] / cos^4 a

= [sin a cos^2 a + cos^2 a - cos a cos^2 a - sin a + 1 + cos^2 a] / cos^4 a

= (2 cos^2 a - sin a + 1) / cos^4 a

Now, we can simplify the expression further using the identity:

1 + tan^2 a = sec^2 a

tan^2 a = sec^2 a - 1

tan a + sec a - 1 = (tan^2 a + 1) / (sec a + tan a - 1)

= (sec^2 a - 1 + 1) / (sec a + tan a - 1)

= sec a / (sec a + tan a - 1)

tan a - sec a + 1 = -(sec a - tan a - 1)

= -(1 / (sec a - tan a + 1))

Substituting these values in the original expression, we get:

(sec a / (sec a + tan a - 1)) - (-1 / (sec a - tan a + 1)) / (1 + sin a cos a)

= (sec a (sec a - tan a + 1) + (tan a - 1)) / ((sec a + tan a - 1)(sec a - tan a + 1)(1 + sin a cos a))

= [(sec^2 a - sin a + 1) + (tan a - 1)] / (cos^2 a (1 + sin a cos a))

= [(2 cos^2 a - sin a + 1)] / (cos^4 a (1 + sin a cos a))

Thus, we have simplified the given expression to (2 cos^2 a - sin a + 1) / (cos^4 a (1 + sin a cos a)).

n = 2

To check, we can substitute 2 back into the original equation:

Step-by-step explanation: The opposite angles of a parallelogram are congruent (equal). ∠A = ∠C and∠D = ∠B.

x is 137 because the opposite angle is congruent.
y is 43 because a parallelogram is equal to 360 degrees, so we would subtract the angles we already know (137+137) from the 360 which leaves you with 86. Since opposite angle are the same you’d have to divide 86 to make it equal for both opposite sides. So 43 on y and its opposite angle.

Company revenue quadratic function.

Angel

The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?

To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:

r(x) = a(x - h)^2 + k

where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

We can use the given revenue values to set up a system of three equations:

2.7 = a(0 - h)^2 + k

3.4 = a(1 - h)^2 + k

2.7 = a(6 - h)^2 + k

Subtracting the first equation from the second, and the first equation from the third, we get:

0.7 = a(1 - h)^2

0 = a(6 - h)^2

Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:

6 - h = 10

which gives us h = -4.

Substituting h = -4 into the first equation, we get:

2.7 = a(0 - (-4))^2 + k

2.7 = 16a + k

Substituting the revenue value for 2005, we get:

3.9 = a(3 - (-4))^2 + k

3.9 = 49a + k

Solving for a and k, we get:

a = -0.1

k = 4.3

Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:

r(x) = -0.1(x + 4)^2 + 4.3

The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?

We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:

3 - 4 + 5 - 6 + ... + 101

We can group the terms into pairs:

(3 - 4) + (5 - 6) + ... + (99 - 100) + 101

Each pair of terms adds up to -1, so we can simplify the expression to:

-1 -1 -1 ... -1 + 101

where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:

-50 + 101 = 51

Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

First five terms of the sequence are 4, 5, 9, 14, and 23.

For the given sequence an = an-1 + an-2, with a1 = 4 and a2 = 5:

1. Its first term is a1 = 4.
2. Its second term is a2 = 5.
3. To find the third term, use the formula: a3 = a2 + a1 = 5 + 4 = 9.
4. For the fourth term, apply the formula again: a4 = a3 + a2 = 9 + 5 = 14.
5. Finally, for the fifth term: a5 = a4 + a3 = 14 + 9 = 23.

So, the first five terms of the sequence are 4, 5, 9, 14, and 23.

The correct answer to the given question about possibility of the license plate is 7, 894, 720.

This problem involves counting the number of possible license plates that can be created with certain restrictions. The first two digits must be odd and repetition is not permitted. The remaining five characters can be any uppercase letter, also without repetition. By using the multiplication principle of counting, we can calculate the total number of possible license plates by multiplying the number of choices for each character position. In this case, we obtain a total of 7,894,720 possible license plates. For the first digit, there are 5 odd digits to choose from (1, 3, 5, 7, 9). After choosing the first odd digit, there are only 4 odd digits left to choose from for the second digit since repetition is not permitted.

For the third, fourth, and fifth characters, there are 26 uppercase letters to choose from for each character, with repetition not permitted. Therefore, the total number of possible license plates is:

5 × 4 × 26 × 26 × 26 × 26 × 26 = 7,894,720

So the correct answer is 7,894,720.

The probability that a student randomly selected from a class of 60 students will be a male who has brown hair is (1/6).

Let's analyze each statement

Statement 1: One-half of the students have brown hair.

Statement 2: One-third of the students are males.

To determine the probability of selecting a male student who has brown hair randomly, we need to find the intersection of these two probabilities. That is, we need to find the probability of the number of students who have brown hair and the number of students who are males.From statement 1, the probability of selecting a student with brown hair is 1/2. Therefore, the number of students with brown hair is (1/2) * 60 = 30.

From statement 2, the probability of selecting a male student is 1/3. Therefore, the number of male students is (1/3) * 60 = 20.Since we need to find the probability of selecting a male student who has brown hair randomly, we need to find the probability that the student is male and has brown hair.
