All sides of the given rhombus measure 5 cm respectively.

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry.

The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

Quadrilaterals having four congruent sides are called squares.

Squares are rhombuses by definition since they are quadrilaterals with four congruent sides.

So, consider the following values: AC = 8 cm, BD = 6 cm, OD = OB = 3 cm, and OA = OC = 4 cm.

Now,

OB² + OC² = BC²

3²+ 4² = BC²

9 + 16 = BC²

25 = BC²

5 = BC

A rhombus has an equal number of sides.

Therefore, all sides of the given rhombus measure 5 cm respectively.

The statement that could be true for g is g(-4) = -11.

What is a function?

A function is a mathematical relationship between a set of inputs (called the domain) and a set of outputs (called the range), where each input has a unique output. In other words, for every value of x in the domain, there is exactly one corresponding value of g(x) in the range.

For the given function g, the domain is -20 ≤ x ≤ 5 and the range is -5 ≤ g(x) ≤ 45. We also know that g(0) = -2 and g(-9) = 6.

To determine which statement could be true for g, we can check each option against the given domain and range, as well as the known values of g(0) and g(-9):

g(7) = -1: This statement is not necessarily true, as g(7) may fall outside the given range of -5 ≤ g(x) ≤ 45.

g(-13) = 20: This statement is not necessarily true, as g(-13) may fall outside the given domain of -20 ≤ x ≤ 5.

g(-4) = -11: This statement could be true, as -20 ≤ -4 ≤ 5 and -5 ≤ -11 ≤ 45. However, we cannot confirm this without additional information.

A $900 item on the sale of 20% discount the

Money off: $180

Amt. of tax: $50.40

Money paid: $770.40

Final price: $770.40

what is discount ?

A discount is a reduction in the price of an item or service, often offered as a promotion or incentive to encourage customers to make a purchase. The discount is usually expressed as a percentage of the original price and represents the amount of money that the customer can save on the purchase.

For example:

Percentage discount: a certain percentage of the original price is deducted from the selling price. For example, a 20% discount on a $100 item would reduce the price to $80.

According to the question:
To calculate the final price of the item with sales tax, we can follow these steps:

Calculate the amount of money off by multiplying the original price by the discount percentage:

Money off = 0.20 x $900 = $180.

Calculate the price after the discount by subtracting the money off from the original price:

Price after discount = $900 - $180 = $720.

Calculate the amount of sales tax by multiplying the price after discount by the tax rate:

Amount of tax = 0.07 x $720 = $50.40.

Calculate the money paid by adding the price after discount and the amount of tax:

Money paid = $720 + $50.40 = $770.40.

Therefore, the final price with 7% sales tax is $770.40.

The answer is C

The probability that the number of heads would take a value within one standard deviation from the mean is 0.6826. This can be found by using the normal approximation to binomial probabilities.

First, we need to find the mean and standard deviation of the binomial distribution. The mean of a binomial distribution is given by np, where n is the number of trials and p is the probability of success. In this case, n = 100 and p = 0.5 (since it is a fair coin), so the mean is 100 * 0.5 = 50.

The standard deviation of a binomial distribution is given by √(np(1-p)). In this case, the standard deviation is √(100 * 0.5 * (1-0.5)) = √(25) = 5.

Now, we can use the normal approximation to find the probability that the number of heads is within one standard deviation from the mean. This is equivalent to finding the probability that the number of heads is between 45 and 55 (since the mean is 50 and the standard deviation is 5).

Using the normal approximation, we can find the z-scores for 45 and 55:

z = (x - μ) / σ

z1 = (45 - 50) / 5 = -1

z2 = (55 - 50) / 5 = 1

Now, we can use a z-table to find the probability that the number of heads is between 45 and 55. The probability that the number of heads is less than 55 is 0.8413, and the probability that the number of heads is less than 45 is 0.1587. So, the probability that the number of heads is between 45 and 55 is 0.8413 - 0.1587 = 0.6826.

The Cartesian coordinates (1, -5) are equivalent to the polar coordinates (√26, 4.910188838655984) with r > 0 and 0 ≤ θ < 2π.

To convert the Cartesian coordinates (1, -5) to polar coordinates with r>0 and 0≤θ<2π, we need to use the following formulas:
r = √(x^2 + y^2)
θ = tan^-1(y/x)

First, let's find the value of r:
r = √(1^2 + (-5)^2)

r = √(1 + 25)

r = √26

Now, let's find the value of θ:
θ = tan^-1((-5)/1)

θ = tan^-1(-5)

θ = -1.373400766945016

Since we need the angle to be between 0 and 2π, we can add 2π to the negative angle to get the positive equivalent:

θ = -1.373400766945016 + 2π

θ = 4.910188838655984

Therefore, the polar coordinates of the Cartesian coordinates (1, -5) are (r, θ) = (√26, 4.910188838655984).

So the answer is:
r = √26
θ = 4.910188838655984

The total number of students in Class 705 is 32.

Let's start by using algebra to solve the problem. Let's assume that the total number of students in Class 705 is "x". We know that 12 students returned their permission slips on the first day, so the number of students who have not returned their slips is (x-12).

On the second day, 15% of the remaining students returned their slips, which means that 0.15(x-12) students returned their slips. We also know that a total of three permission slips were returned on the second day, so we can write an equation:

0.15(x-12) = 3

Simplifying this equation:

0.15x - 1.8 = 3

0.15x = 4.8

The statements that are true are

The relative minimum function is (3, 0)

When t > 3 the function will increase

To find the maximum and minimum of a function, find the points where the function's derivative is equal to zero or undefined. These points are called critical points.

We then evaluate the function at these critical points and at the endpoints of the interval to determine the maximum and minimum values. To find the critical points of the function find the derivatives of the given function

Here we have a graph

The graph shows the number of coins in a person's collection

The function is defined as f(t) = t³ - 6t² + 9t  

To find the maximum and minimum of the function

Find the critical points where the derivative is equal to zero or undefined.

Differentiate f(t) with respect to t

=> f'(t) = 3t² - 12t + 9  

Now, set the derivative equal to zero and solve for t  

=> 3t² - 12t + 9 = 0

=> t² - 4t + 3 = 0  divide by 3

On Factoring the quadratic equation, we get:

=> (t - 3)(t - 1) = 0

=> t = 3 and t = 1

Therefore,

The critical points of the graph are t = 1 and t = 3.

Now differentiate f'(t) with respect to t

=> f''(t) = 6t - 12

At t = 1, f''(1) = 6 - 12 = - 6, which is less than zero.

Hence, f(t) has a local maximum at t = 1.

At t = 3, f''(3) = 18 - 12 = 6, which is greater than zero.

Hence, f(t) has a local minimum at t = 3.

At t = 4, f''(4) = 24 - 12 = 12

At t = 5, f''(5) = 30 - 12 = 18

Hence, f(t) will increase when t > 3

Step-by-step explanation:

To find the x-intercepts of the quadratic function f(x) = x^2 + 6x - 27, we need to set f(x) equal to zero and solve for x.

So we have:

f(x) = 0

x^2 + 6x - 27 = 0

We can solve for x using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Where a = 1, b = 6, and c = -27.

Substituting these values into the quadratic formula, we get:

x = (-6 ± sqrt(6^2 - 4(1)(-27))) / 2(1)

x = (-6 ± sqrt(180)) / 2

x = (-6 ± 6sqrt(5)) / 2

x = -3 ± 3sqrt(5)

So the x-intercepts of the quadratic function are approximately -10.16 and 4.16.

The simplified expression is (3y-7)/(y^2-35)/3.

To simplify the given expression, we need to find the least common denominator (LCD) of the two fractions. The LCD of (y-5) and (y+7) is (y-5)(y+7).
Next, we need to multiply each fraction by the LCD in order to get the same denominator for both fractions.
(2)/(y-5) * (y+7)/(y+7) + (7)/(y+7) * (y-5)/(y-5)
= (2y+14)/(y^2-35) + (7y-35)/(y^2-35)

Now, we can combine the two fractions since they have the same denominator.
(2y+14+7y-35)/(y^2-35)
= (9y-21)/(y^2-35)
Finally, we can simplify the fraction by factoring out a 3 from the numerator.

To find the total amount of nuts Martin buys, we need to add the amount of peanuts and the amount of almonds he buys.

First, we need to convert the mixed numbers to improper fractions. To do this, we multiply the whole number by the denominator and add the numerator. For 2(5)/(6), we multiply 2 by 6 and add 5 to get 10/6. For 4(3)/(4), we multiply 4 by 4 and add 3 to get 19/4.

Next, we need to find a common denominator in order to add the two fractions. The least common denominator for 6 and 4 is 24, so we multiply the numerator and denominator of 10/6 by 4 to get 40/24 and the numerator and denominator of 19/4 by 6 to get 57/24.

Finally, we add the two fractions by adding the numerators and keeping the same denominator: 40/24 + 57/24 = 97/24.

1. ∠N ≅ ∠Q (given)

2. Side NP ≅ Side QS (given)

3. Side OP ≅ Side RS (additional information needed)

Hence, option d is the correct answer.

To prove that \[ A^{n}=\left[\begin{array}{ccc} a^{n} & n a^{n-1} & \frac{n(n-1)}{2}a^{n-2} \end{array}\right], we will use mathematical induction.

Base case: For \( n=1 \), \( A^{1}=A \). This is true since
\[ A=\left[\begin{array}{ccc} a & 1 & 0 \\ 0 & a & 1 \\ 0 & 0 & a \end{array}\right] \]
which matches the left side of our equation.

Inductive step: Assume that the statement is true for some \( n=k \), i.e.
\[ A^{k}=\left[\begin{array}{ccc} a^{k} & ka^{k-1} & \frac{k(k-1)}{2}a^{k-2} \end{array}\right] \]
We will now show that it is true for \( n=k+1 \).
\[ A^{k+1}=A^{k}\cdot A \]

We substitute the induction hypothesis into this equation and get:
\[ A^{k+1}=\left[\begin{array}{ccc} a^{k} & ka^{k-1} & \frac{k(k-1)}{2}a^{k-2} \end{array}\right]\cdot \left[\begin{array}{ccc} a & 1 & 0 \\ 0 & a & 1 \\ 0 & 0 & a \end{array}\right] \]

Calculating the matrix product yields:
\[ A^{k+1}=\left[\begin{array}{ccc} a^{k+1} & (k+1)a^{k} & \frac{(k+1)k}{2}a^{k-1} \end{array}\right] \]
