Explanation:

Points A, C, U, D, S and E are all in the bottom floor plane. A plane is a flat surface, and saying "points are coplanar" means the points are all on the same plane.

Points like R, T and B are not on the floor plane, so they are not coplanar with the other points mentioned in the previous paragraph.

In other words, point R is not coplanar with points C, D and E since R is not on the floor plane with C,D,E.

Answer:

9.22

Step-by-step explanation:

use the distance between 2 points formula:

d = √(x2 - x1)² + (y2 - y1)²  and the 2 points (-7, -2) (2, -4)

d = √(2 - -7)² + (-4 - -2)² = √(9² + -2²) = √85 = 9.22

Given the following information: Five years ago, someone used her $40,000 saving to make a down payment for a townhouse in RTP. The house is a three-bedroom townhouse and sold for $200,000 when she bought it. After paying down payment, she financed the house by borrowing a 30-year mortgage.

Mortgage interest rate is 4.25%. Right after closing, she rent out the house for $1,800 per month. In addition to mortgage payment and rent revenue, she listed the following information so as to figure out investment return: 1. HOA fee is $75 per month and due at end of each year 2. Property tax and insurance together are 3% of house value 3. She has to pay 10% of rent revenue for an agent who manages her renting regularly 4. Her personal income tax rate is 20%. While rent revenue is taxable, the mortgage interest is tax deductible. She has to make the mortgage amortization table to figure out how much interest she paid each year 5. In the last five years, the market value of the house has increased by 4.8% per year 6.

Using the definition of slope, the points (-2 , 6), (0 , 2), and (1 , 0) are collinear.

Three or more points are said to be collinear if they lie on a single straight line.

To determine whether the given points are collinear, use the definition of slope. The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.

m = (y2 - y1)/(x2 - x1)

Getting the slope of each pair of points:

(-2 , 6) and (0 , 2)

m = (y2 - y1)/(x2 - x1)

m = (2 - 6)/(0 - -2)

m = -4/2

m = -2

(0 , 2), and (1 , 0)

m = (y2 - y1)/(x2 - x1)

m = (0 - 2)/(1 - 0)

m = -2/1

m = -2

(-2 , 6) and (1 , 0)

m = (y2 - y1)/(x2 - x1)

m = (0 - 6)/(1 - -2)

m = -6/3

m = -2

Since collinear points lies on the same line, the slope of any pair of points should be the same. Since the slopes of each pair of points is equal with each other, then they are collinear.

What you have here is called "the difference of two squares"

Difference means subtraction and both 100x2 and 49 are perfect squares.

The factored form of 100x2-49 is

(10x+7)(10x-7)

Because 10x times 10x is 100x2 and 7 times 7 is 49

One factor has a + and

The length of a rectangle is found to be 18 cm.

An enclosed 2-D shape plane called a rectangle has four sides, four corners, and four right angles (90°). It has equal and parallel opposite sides. Because a rectangle is a two-dimensional form, it has length and width as its two dimensions. The length of a rectangle is considered as its longer side; its breadth is considered as its shorter side.

The perimeter of the rectangle is given as 54 cm. Let's consider the length of the rectangle as x and the width as y.

The formula to calculate the perimeter is 2(x+y).

The length is given as 2y.

Then, the perimeter is,

\(\begin{aligned}\text{Perimeter}&=2(2y+y)\\&=4y+2y\\&=6y\\54&=6y\\y&=\frac{54}{6}\\&=9\end{aligned}\)

Then, the length is 2y=2×9=18.

The answer is 18 cm. Therefore, the correct option is option a.

Step-by-step explanation:

Sin(x + 2π) is equivalent to sin(x) for all x, and since the limit of sin(x) as x approaches infinity exists, it must be equal to L as well.  But this contradicts the fact that sin(x) is not a constant function.

To show that if lim(x→∞) f(x) exists, then f(x) is a constant function, we can use the fact that f(x) is periodic with a period T.

Let's assume that lim(x→∞) f(x) exists and denote it as L.

Now, let's consider f(x + T), which is equivalent to f(x) due to the periodicity of f(x) with period T. As x approaches infinity, x + T also approaches infinity.

Since lim(x→∞) f(x) exists and is equal to L, it implies that lim(x→∞) f(x + T) also exists and is equal to L.

However, f(x + T) is equivalent to f(x) for all x, and since the limit of f(x) as x approaches infinity exists, it must be equal to L as well.

Therefore, we can conclude that f(x) is a constant function, as its value is L for all x.

Now, let's deduce that lim(x→∞) sin(x) does not exist.

Since sin(x) is a periodic function with a period of 2π, it satisfies the condition of being a periodic function.

Assuming that the limit lim(x→∞) sin(x) exists, let's denote it as L.

Now, let's consider sin(x + 2π), which is equivalent to sin(x) due to the periodicity of sin(x) with a period of 2π. As x approaches infinity, x + 2π also approaches infinity.

Since lim(x→∞) sin(x) exists and is equal to L, it implies that lim(x→∞) sin(x + 2π) also exists and is equal to L.

However, sin(x + 2π) is equivalent to sin(x) for all x, and since the limit of sin(x) as x approaches infinity exists, it must be equal to L as well.

But this contradicts the fact that sin(x) is not a constant function.

Therefore, we can conclude that lim(x→∞) sin(x) does not exist.

Given that 235 out of 1100 people said that they had heard of the new beverage, we can say that the population proportion of people who know of the beverage is not 0.18 using the z test.

A z test of proportion will assess whether or not a sample from a population represents the true proportion of the entire population.

Here we want to test

H0: population proportion of people who knew the new drink was 0.18.

(p = 0.18)

H1: population proportion of people who knew the new drink wasn't 0.18.

(p ≠ 0.18)

The appropriate test statistic is:

z =  \(\frac{p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }\)

where \(p_0\) is the population proportion under null hypothesis i.e., 0.18 here.

p is the sample proportion given.

In the given question, 235 out of 1100 people said they had heard of the new beverage.

So, p = 235/1100 = 0.2136

n = sample size = 1100 for the given question.

Thus, z = \(\frac{0.213-0.18}{\sqrt{\frac{0.18(1-0.18)}{1100} } }\) = 2.9

Using the standard normal table, we should reject the null hypothesis at 10% level of significance if z calculated value is greater that 1.28

Since, 2.9 > 1.28, we shall reject the null hypothesis at 10% level of significance.

Step-by-step explanation:

The atmospheric pressure on the surface of the Moon can be calculated as 0.1653 times the reading on the mercury-based manometer. When returning to sea level on Earth, the atmospheric pressure would be the standard atmospheric pressure of 101.3 kPa.

The gravity on the Moon is approximately 16.53% of that on Earth. Since the pressure in a liquid column is directly proportional to the height of the column, we can assume that the height of the mercury column in the manometer on the Moon corresponds to the atmospheric pressure. Therefore, the atmospheric pressure on the Moon would be 0.1653 times the reading on the manometer.

When the manometer is brought back to sea level on Earth, the gravitational force acting on the mercury column would be significantly higher due to the stronger gravitational pull. The atmospheric pressure at sea level on Earth is typically around 101.3 kPa, which is considered as the standard atmospheric pressure. Therefore, the reading on the manometer would correspond to the standard atmospheric pressure of 101.3 kPa.

Function f is defined for all values of x in the closed interval [1, 5] is not necessary for the existence of a value c in the open interval (1, 5) where f(c) = 0. Correct answer is option (D).

To ensure that there exists a value c in the open interval (1, 5) such that f(c) = 0, the condition that ensures this is (C) f is continuous on the closed interval [1, 5].

If f is continuous on the closed interval [1, 5], then by the Intermediate Value Theorem, we know that if f(1) = -2 and f(5) = -7, there must exist a value c between 1 and 5 where f(c) crosses the x-axis and equals 0.

Option (A) f(x) dr exists does not provide any information about the function's behavior or whether it crosses the x-axis.

Option (B) f is increasing on the closed interval [1, 5] does not guarantee that f will intersect the x-axis or equal 0 within the open interval (1, 5).

Option (D) f is defined for all values of x in the closed interval [1, 5] is not necessary for the existence of a value c in the open interval (1, 5) where f(c) = 0.

Therefore, the correct condition that ensures f(c) = 0 for some value c in the open interval (1, 5) is that f is continuous on the closed interval [1, 5].
