Y is the midpoint of XZ and W is the midpoint of VX. If VZ = s + 14 and WY = s, the value of s is 14.

The point that divides a line segment into two equal halves is known as the midway in geometry. A point that divides a line segment into two equal halves is the midpoint of the segment. In other words, the line segment's midpoint is precisely in the middle. The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

Given,

VZ = s + 14

WY = s

VZ bisects WY

VZ = 2WY

s + 14 = 2(s)

s + 14 = 2s

2s - s = 14

s = 14

Y is the midpoint of XZ and W is the midpoint of VX. If VZ = s + 14 and WY = s, the value of s is 14.

There are 6 of these square faces, so their total area is ...

  6 × 49 m² = 294 m²

The lateral area of the prism is 294 m².

Answer:

The inequality has two prime solutions. To determine the number of prime solutions that the inequality has, we need to first solve the inequality to find its solutions. Since the inequality involves a polynomial, we can use the techniques of algebraic manipulation and factoring to solve it.

We begin by multiplying out the left-hand side of the inequality to obtain:

(n²-17)(n²-100)≤0

This expression can be further simplified by multiplying out the terms in the brackets, which gives us:

n⁴ - 117n² + 1700 ≤ 0

To solve this inequality, we need to find the values of n that make the left-hand side equal to zero. We can do this by setting the expression equal to zero and then factoring it to obtain:

n⁴ - 117n² + 1700 = 0

n² (n² - 117) + 1700 = 0

(n² - 19)(n² - 90) + 1700 = 0

(n² - 19)(n² - 90) = -1700

To find the solutions of this equation, we need to find the values of n that make the left-hand side equal to zero. We can do this by setting each factor equal to zero and solving for n:

n² - 19 = 0 or n² - 90 = 0

n² = 19 or n² = 90

n = ±√19 or n = ±√90

Since the problem states that n is a prime number, we need to consider only the solutions where n is a prime number. Of the solutions above, only n = ±√19 and n = ±√90 are prime numbers, so these are the only solutions that we need to consider. Since there are two such solutions, the inequality has two prime

Answer:

False

Step-by-step explanation:

False. A material in which thermal energy is transferred slowly is actually an insulator. A conductor is a material that easily allows the transfer of thermal energy. This is because conductors have loosely bound electrons that can move freely through the material, allowing heat to be easily transferred. Examples of good conductors include metals such as copper, aluminum, and silver. On the other hand, insulators have tightly bound electrons that do not move easily, making them poor conductors of heat. Examples of good insulators include materials like glass, plastic, and rubber.

Measure of angle ABE is 47°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles. The angle formed by the rays lying perpendicular to the two crossing curves at the point of junction is another property of intersecting curves. Angle can also refer to the length of a rotation or an angle. This metric represents the relationship between a circular arc's length and radius.

Given

∠CBE = 43°

As we know, ∠ABC is a right angle

∠ABC = ∠ABE + ∠CBE

90 = ∠ABE +43

∠ABE = 90 - 43

∠ABE = 47

Answer:

A.) All reptiles run fast

Step-by-step explanation:

Tortoises are reptiles that run slow, so they would be a counterexample to the conjecture that all reptiles run fast. This is because tortoises are a type of reptile that do not run fast, even though the conjecture states that all reptiles do.

In general, reptiles are a class of animals that includes many different species. Some reptiles, such as snakes and lizards, are known for their speed and agility. However, other reptiles, such as tortoises and turtles, are not known for their speed and tend to move much slower than other reptiles. This shows that the conjecture that all reptiles run fast is not always true, and tortoises are a counterexample to this conjecture.

In addition to their speed, tortoises are also distinguished by their hard shells and thick legs. They are typically found in warm, dry environments, and they are known for their long lifespan and low metabolic rate. They are also typically herbivores, feeding on a diet of plants and vegetation. This is in contrast to other reptiles, such as snakes and lizards, which are often carnivorous and hunt for their food. Overall, tortoises are a unique and interesting group of reptiles that do not always fit the generalizations made about reptiles.

The rent per unit should be $8,354.22 to generate a Net Operating Income (NOI) of $100,000, given the vacancy rate and operating expenses.

The operating expenses are costs that must be deducted from the gross operating income to arrive at the net operating income.

The operating expenses do not include some period expenses, which are indirect costs.

Vacancy Rate (5% of Potential Gross Income)                   7,519

Effective Gross Income                                                $142,857

Operating Expenses (30% of Effective Gross Income) 42,857

Net Operating Income (NOI)                                      $100,000

Number of Units 18

Gross operating income = net operating income + operating expenses

Operating expenses = 30% of effective gross income

Net operating income = 70% of effective gross income (100 - 30%)

= $100,000

Effective Gross Income (100%) = $142,857 ($100,000 ÷ 70%)

Vacancy rate = 5% of potential gross income

Effective Gross Income = 95% (100 - 5)

Potential gross income = $150,376 ($142,857 ÷ 95%)

Number of units = 18

Rent per unit = $8,354.22 ($150,376/18)

Rent per month = $696.19 ($8,354.22 ÷ 12)

The option that applies to 2cos(x)+sqrt2=0 less than x less than 2pi is options C and D:

c.5pi/4

d.7pi/4

To solve this equation, we can start by isolating the cosine term on one side of the equation:

[tex]2cos(x) = -\sqrt{2[/tex]

[tex]cos(x) = \sqrt{\frac{2}{2} } }[/tex]

The cosine function has a range of [-1, 1], so the only possible value for cos(x) is -sqrt(2)/2. This means that the only solution to the equation is x = acos(-sqrt(2)/2).

The inverse cosine function, denoted as "arccos," gives us the angle whose cosine is a given value. In this case, we want to find the angle whose cosine is -sqrt(2)/2. The domain of the arccos function is [-1, 1], so the range of the function is [0, pi]. This means that the solution x must be an angle in the range [0, pi].

Since the problem specifies that the solution must be in the range [0, 2pi], we need to consider all possible angles in that range that satisfy the equation. This means that the possible solutions are:

[tex]x = acos(-\sqrt (2)/2) + 2\pi *k[/tex]

where k is an integer.

Substituting the values from the given choices into this equation, we find that the possible solutions are:

[tex]a. x = acos(-\sqrt{\frac{2}{2} } + 2\pi 0 = \pi /4 + 0 = \pi /4\\b. x = acos(-\sqrt{\frac{2}{2} } + 2\pi 1 = \pi /4 + 2\pi = 3\pi /4\\c. x = acos(-\sqrt{\frac{2}{2} } + 2\pi 2 = \pi /4 + 4\pi = 5\pi /4\\d. x = acos(-\sqrt{\frac{2}{2} } + 2\pi 3 = \pi /4 + 6\pi = 7\pi /4[/tex]

Step-by-step explanation:

The amount of money on the card decreases by $1.43 per week. The slope is a measure of the steepness of a line

The slope can be positive, negative, or zero. A positive slope means that the line slopes upward from left to right, which means that the value of the dependent variable (in this case, M) increases as the value of the independent variable (t) increases. A negative slope means that the line slopes downward from left to right, which means that the value of the dependent variable decreases as the value of the independent variable increases.

To find the linear equation that models the data, we need to find the slope of the line. The slope is calculated by using the formula:

slope =[tex](y_2 - y_1) / (x_2 - x_1)[/tex]

Where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two points on the line. In this case, we can use week 0 and week 14 as our two points. Let's say that at week 0, M = $100 and at week 14, M = $80. Then the slope would be:

slope = ($80 - $100) / (14 - 0) = -$20 / 14 = -$1.43

So the linear equation that models the data is:

M = -$1.43 * t + $100
