If opposite sides are congruent (but not all sides are equal) and diagonals are congruent then the quadrilateral is a______

Answer:

\(4\)

Step-by-step explanation:

Simplify the expression

Hence, x > 14.5 is the answer to the contradiction 12 + 6x > 99. This suggests that the inequality will be satisfied by any x value that is bigger than 14.5

"Inequality" in mathematics refers to the relationship between two reactions and quantities that is not the same as one another. As a result, inequality results from an imbalance.

You can use algebra to isolate one variable x solely on a single side of the inequality and utilize that information to solve the inequality 12 + 6x > 99.

The stages to resolving the inequality are as follows:

First, take 12 away both from sides of the inequality:

12 + 6x - 12 > 99 - 12

Simplify:

6x > 87

Then, to identify the variable x, split both side of the equality by 6:

6x/6 > 87/6

Simplify:

x > 14.5

Answer:

$696.70

Step-by-step explanation:

The formula for the area of a circle is given as πr²

From the above question

π = 3.14

Diameter = 5 feet

Radius = Diameter/2 = 5 feet/2 = 2.5 feet

Hence,

The area of the circular table = 3.14 × 2.5²

= 19.625 ft² or 19.625 square foot

We are told that:

The wood costs $35.50 per square foot

Hence,

1 ft² = $35.50

19.625 ft² = x

Cross Multiply

x = 19.625 ft² × 35.50

x = $696.6875

Approximately = $696.70

Therefore, it will cost Rafael $696.70 to make the table.

Inequality is a statement of an order relationship between two figures or algebraic expressions. Ryan used at least 1189 minutes.

In mathematics, an inequality is a relation which makes a non-equal comparison between two figures or other fine expressions. It's used most frequently to compare two figures on the number line by their size.

Given

Let m be the number of minutes used.

Yearly cost = fixed cost variable cost

fixed cost = 13

Variable cost = 0.05 × m

Yearly cost = 130.05 m

It says in the problem that the least he has been charged in a month is$72.45.

This means that the yearly cost is at least72.45.

In other words, the yearly cost is72.45 or bigger.

This can be expressed as 130.05 m ≥72.45

130.05 m ≥72.45

13- 130.05 m ≥72.45- 13

00.05 m ≥72.45- 13

m ≥59.45

Divide both sides by0.05

m/0.05 ≥59.45/0.05

m ≥ 1189

thus, Ryan used at least 1189 minutes

The inverse of function of f(x) will be p(x) = 7x – 2. Then the correct option is B.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

Let the function will be

f: X → Y

Then the inverse function will be

f⁻¹: Y → X

The function is given below.

f(x) = (x + 2) / 7

Substitute p(x) in place of x and x in place of f(x). Then the equation of the inverse function will be

x = [p(x) + 2] / 7

Solve the equation for p(x), then the equation of the inverse function will be

p(x) + 2 = 7x

     p(x) = 7x – 2

Thus, the inverse of function of f(x) will be p(x) = 7x – 2.

The APR, or stated rate, is calculated as the annualized interest rate expressed as a percentage.

The APR, or stated rate, represents the annualized interest rate on a loan or investment, expressed as a percentage.

To calculate the APR, we need to consider the nominal interest rate and the compounding frequency. The formula to calculate the APR is:

APR = (1 + nominal interest rate/compounding periods)^(compounding periods) - 1

The nominal interest rate is the stated rate without taking compounding into account.

The compounding periods refer to the number of times interest is compounded in a year, typically based on daily, monthly, or quarterly periods.

By applying the formula and considering the appropriate compounding periods, we can determine the APR.

The APR is an important metric as it allows for easy comparison of interest rates across different financial products.

It helps consumers and investors understand the true cost or yield associated with a loan or investment and enables them to make informed decisions.

The statement "Cos(x) = Cos(-x) for x ∈ R, where x is the angle in standard position" is true.

In the trigonometric function cosine, the cosine of an angle measures the ratio of the adjacent side to the hypotenuse in a right triangle. The cosine function is an even function, which means it has symmetry about the y-axis. This symmetry property implies that the cosine of an angle is equal to the cosine of its negative angle.

When we consider angles in standard position, positive angles are measured counterclockwise from the positive x-axis, and negative angles are measured clockwise from the positive x-axis. Since the cosine function is even, the cosine values of an angle and its negative angle are equal.

Therefore, for any real value of x, the equation Cos(x) = Cos(-x) holds true.

The root of the equation is rational for any real value of a where a>0. if a=0, the equation has a single root which is real and rational.

In mathematics, the number that results in the initial number when multiplied by itself is called the root. For instance, 7 is the square root of 49 since 77=49. Because 49 is created by multiplying 7 by itself twice in this instance, we refer to 7 as the square root of 49. Since 333=27, the cube root of 27 is 3.

The given equation is 2x + a(x-a) = 0. Simplifying, we get:

\($\begin{align*}2x + ax - a^2 &= 0 \x(2+a) &= a^2 \x &= \frac{a^2}{2+a}\end{align*}\)

Therefore, the root of the equation is \(\frac{a^2}{2+a}$\).

To show that this root is rational for any real value of a where a>0, we need to show that \(\frac{a^2}{2+a}$\) can be expressed as a ratio of two integers.

Let \($p=a^2$\) and q=2+a. Since a>0, we have p>0 and q>0. Therefore, \(\frac{p}{q}$\) is a rational number.

Thus, the root of the equation is rational for any real value of a where a>0.

If a=0, the given equation becomes 2x=0, which has only one root, x=0. Therefore, if a=0, the equation has a single root which is real and rational.

The probability that none of the calculators in a random sample of four is defective is 0.6561.

To calculate the probability, we use the concept of independent events. Each calculator's defectiveness is assumed to be independent of others, meaning the probability of one calculator being defective does not affect the probability of another calculator being defective.

The probability of one calculator not being defective is obtained by subtracting the probability of it being defective (10%) from 1. Since we have four calculators, we multiply the probabilities of each calculator not being defective together.

P(None defective) = (0.90) * (0.90) * (0.90) * (0.90) = 0.6561.
