Answer:

y = (-1/2)x + 21/2

Step-by-step explanation:

Given equation:

y - 2x + 7

Coordinates = (5,8)

Find:

Perpendicular equation

Computation:

y = mx + c

y - 2x + 7

y = 2x - 7

So,

m = 2

The negative reciprocal of 2 is -1/2

So,

For,

Coordinates = (5,8)

y = mx + c

8 = (-1/2)(5) + c

8 = -5/2 + c

c = 8 + 5/2

c = 21 /2

So,

y = mx + c

y = (-1/2)x + 21/2

Answer:

No, because they are parallel.

Step-by-step explanation:

The lines \(p\) and \(m\) will not intersect, so Kevin is not correct.

It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.

Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.

So, line p and m will not intersect.

Thus the answer is " No, because they are parallel."

sample size of 6945 parents.

To determine the sample size, we can use the formula:

n = ((z*σ)/E)^2

where:

z = the z-score associated with the confidence level (98% confidence level corresponds to a z-score of 2.33)

σ = the population standard deviation (given as 35.8 dollars)

E = the margin of error (10 dollars)

Substituting the given values, we get:

n = ((2.33*35.8)/10)^2

n = (83.414)^2

n = 6944.4

Rounding up to the nearest A, we get a sample size of 6945 parents.

Based on the given information, the claim that can be made about f(x) is that it has a vertical asymptote at x = 4.

The limit of f(x) as x approaches 4 is infinity, which suggests that f(x) becomes arbitrarily large as x gets closer to 4. This behavior indicates that there is a vertical asymptote at x = 4. A vertical asymptote is a vertical line that a function approaches but never crosses. In this case, as x approaches 4, f(x) goes to infinity, indicating that the function becomes unbounded near x = 4.

The other claims, such as f(x) having a horizontal asymptote at y = 4 or being continuous at x = 4, cannot be deduced from the given information. The limit of f(x) as x approaches infinity is not specified, so it is unknown whether f(x) approaches infinity or any other value as x tends to infinity. The continuity of f(x) at x = 4 cannot be determined solely based on its limits; it requires additional information about the function's behavior in the vicinity of x = 4. Therefore, the only valid claim that can be made is the presence of a vertical asymptote at x = 4.

Therefore , the solution of the given problem of standard deviation comes out to be correct option is (A)Barnsboro Bank has more variation.

Variance is measured in statistics using variance. The average variation between the data and the mean is calculated by taking the square root of that value. By comparing each value to the mean, it incorporates all data points in its computations, in contrast to some other quantitative measures of variability. Variations may occur due to internal or external factors, and they may include things like unintentional errors, exaggerated expectations, and changing commercial or economic conditions.

The volume of a right square pyramid with base side length 103 and height 12 is 42,236 cubic units.

Volume is a measure of the amount of space an object occupies, or the capacity of a container. It is usually measured in liters, gallons, or cubic meters.

The volume of a right square pyramid is calculated using the formula V = (1/3) * (base area) * (height). In this case, the base area is equal to the square of the length of the sides of the base (s²).

Therefore, the volume of the right square pyramid can be calculated as follows:

V = (1/3) * (s²) * (h).

Plugging in the values given in the question, we get

V = (1/3) * (103²) * (12) = 42,236 cubic units.

This is the volume of the right square pyramid with the given dimensions.

To summarize, the volume of a right square pyramid with base side length 103 and height 12 is 42,236 cubic units.

If someone says they will meet you again in 31 days on a Monday, then that meeting would occur on a week day of Thursday. so, the correct answer is E).

To determine the day of the week that is 31 days from a Monday, we can use the fact that there are seven days in a week. Since 31 is not evenly divisible by 7, we cannot simply add or subtract a certain number of days to find the day of the week.

Instead, we must use modular arithmetic. Specifically, we can take the remainder of 31 divided by 7, which is 3. This means that after 31 days, we will be three days ahead of Monday, so the day will be Thursday. Therefore, the day of the week that is 31 days from a Monday is Thursday.

The scale factor for the dilation of triangle ABC to produce triangle ABC is B 0.5 and  C 2.

This is because the points for the triangles,

point A (-2, 2) (0.5) = (-1, 1) A'

point B (-2, -1) (0.5) = (-1, -0.5) B'

point C (3, -1) (0.5) = (1.5, -0.5) B'

Every coordinate point of the original triangle is multiplied by the scale factor 2. Therefore, the dilated triangle will be A’B’C’ and the coordinate points obtained are

point A (-2, 2) (2) = (-4, 4) A'

Because the graph always has a consistent slope of +2, the table x|y-2| 4|0| 6|2| is an illustration of a linear function table.

In order for a table to represent a linear function, there must be a constant rate of change (slope) between any two points on the graph. In other words, the relationship between the x-values and y-values should follow a consistent pattern.

The correct table that represents a linear function is: x|y-2| 4|0| 6|2|This is because there is a constant rate of change of +2 between any two points on the graph. For example, when x goes from 2 to 4, y increases from -2 to 0. When x goes from 4 to 6, y increases from 0 to 2.

This constant rate of change indicates that the relationship between x and y is linear.

In summary, a table represents a linear function when there is a constant rate of change between any two points on the graph. The table x|y-2| 4|0| 6|2| is an example of a linear function table because there is a consistent slope of +2 between any two points on the graph.

The expression ∫C (F →) · (d → r →) is the line integral of the dot product between the vector field F → and the differential displacement vector d → along the curve C, measuring their alignment along the curve.

The expression ∫C (F →) · (d → r →) represents the line integral of the dot product between a vector field F → and a differential displacement vector d → along a curve C.

Let's break down the components:

- ∫C denotes the line integral, which represents the cumulative sum of a quantity along a curve. In this case, we integrate over the curve C.

- F → represents a vector field, where each point in space has an associated vector. The vector field F → could represent physical quantities such as velocity, force, or any other vector-valued property.

- (d → r →) represents the differential displacement vector along the curve C. This vector describes an infinitesimally small displacement along the curve at each point.

- · denotes the dot product between two vectors. The dot product of two vectors yields a scalar quantity.

By combining these components, the expression ∫C (F →) · (d → r →) calculates the sum of the dot products between the vector field F → and the differential displacement vector d → as we move along the curve C. This sum is taken over the entire curve, resulting in a single scalar value.

In simpler terms, this line integral measures how much the vector field F → is aligned with the tangent vector to the curve C at each point, and it accumulates this alignment along the entire curve. It provides information about the overall effect or flow of the vector field along the curve C.

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 storm rainfall flux is 0.00127 m2/hr, 1.27 kg liquid water/m2hr, 2.8 lb liquid water/m2hr, 1.27 liters liquid water/m2hr, and 0.335 gallons liquid water/m2hr. The amount of liquid water fell on the garden is 80.6 L, 21.3 gallons.

Dimensions of outdoor vegetable garden = 2 m × 2 m

Storm rainfall = 0.8 inches of rain

Time of storm = 1 hr(

a) The rainfall flux is the amount of rainfall per unit area and unit time. It is given as:

Rainfall flux = (Amount of rainfall) / (Area × Time)

Given the area of the garden is 2 m × 2 m, and the time is 1 hr, the rainfall flux is:

Rainfall flux = (0.8 inches of rain) / (2 m × 2 m × 1 hr)

Converting inches to meters, we get:

1 inch = 0.0254 m

Therefore,

Rainfall flux = (0.8 × 0.0254 m) / (2 m × 2 m × 1 hr) = 0.00127 m/hr

Converting the rainfall flux to other units:

In kg/hr:

1 kg of water = 1000 g of water

Density of water = 1000 kg/m3

So, 1 m3 of water = 1000 kg of water

So, 1 m2 of water of depth 1 m = 1000 kg of water

Therefore, 1 m2 of water of depth 1 mm = 1 kg of water

Therefore, the rainfall flux in kg/hr = (0.00127 m/hr) × (1000 kg/m3) = 1.27 kg/m2hr

In lbs/hr:

1 lb of water = 453.592 g of water

So, the rainfall flux in lbs/hr = (0.00127 m/hr) × (1000 kg/m3) × (2.20462 lb/kg) = 2.8 lbs/m2hr

In liters/hr:

1 m3 of water = 1000 L of water

So, 1 m2 of water of depth 1 mm = 1 L of water

Therefore, the rainfall flux in L/hr = (0.00127 m/hr) × (1000 L/m3) = 1.27 L/m2hr

In gallons/hr:

1 gallon = 3.78541 L

So, the rainfall flux in gallons/hr = (0.00127 m/hr) × (1000 L/m3) × (1 gallon/3.78541 L) = 0.335 gallons/m2hr

(b) To calculate the amount of water that fell on the garden, we need to calculate the volume of water.

Volume = Area × Depth.

The area of the garden is 2 m × 2 m.

We need to convert the rainfall amount to meters.

1 inch = 0.0254 m

Therefore, 0.8 inches of rain = 0.8 × 0.0254 m = 0.02032 m

Volume of water = Area × Depth = (2 m × 2 m) × 0.02032 m = 0.0806 m3

Converting the volume to other units:

In liters:

1 m3 of water = 1000 L of water

Therefore, the volume of water in liters = 0.0806 m3 × 1000 L/m3 = 80.6 L

In gallons:

1 gallon = 3.78541 L

Therefore, the volume of water in gallons = 80.6 L / 3.78541 L/gallon = 21.3 gallons.

The formula for the geometric sequence that begins with the terms 81, 54, 36, and so on is:

aₙ = 81 * (1/3)^(n-1)

To find a formula for a geometric sequence that begins with the terms 81, 54, 36, and so on, we need to determine the common ratio between consecutive terms.

By observing the sequence, we can see that each term is obtained by dividing the previous term by 3. Hence, the common ratio is 1/3.

Let's denote the first term as a₁ and the common ratio as r.

a₁ = 81 (the first term)

r = 1/3 (the common ratio)

The general formula for a geometric sequence is given by:

aₙ = a₁ * r^(n-1)

where aₙ represents the nth term of the sequence.

Substituting the values we have:

aₙ = 81 * (1/3)^(n-1)

The formula for the geometric sequence that begins with the terms 81, 54, 36, and so on is:

aₙ = 81 * (1/3)^(n-1)

Using this formula, you can find any term in the sequence by substituting the corresponding value of n.

For example, to find the 5th term of the sequence, you would substitute n = 5 into the formula:

a₅ = 81 * (1/3)^(5-1)

a₅ = 81 * (1/3)^4

a₅ = 81 * (1/81)

iii. The calculated test statistic is -2.1095.

iv. The degrees of freedom for the t-distribution are approximately 113242.

v. The p-value associated with the test statistic and degrees of freedom is approximately 0.0001.

i. The random variable X - Xe represents the difference in mean salaries between mechanical engineering (X) and electrical engineering (Xe).

ii. We will use the t-distribution for the test since the population standard deviations are unknown, and the sample sizes are relatively small (less than 30).

iii. The test statistic for this hypothesis test is calculated as:

\(t = (X - Xe) / \sqrt(s_m^2 / n_m) + (s_e^2 / n_e))}\)

Where:

X = sample mean for mechanical engineering

Xe = sample mean for electrical engineering

Sm = standard deviation for mechanical engineering

Se= standard deviation for electrical engineering

nm = sample size for mechanical engineering

ne = sample size for electrical engineering

t = (46100 - 46900) / √(3450² / 46) + (4230² / 52))

= -800 / √(3450² / 46) + (4230² / 52))

= -800 / 379.4303

= -2.1095

iv.

Calculating the degrees of freedom:

df = (3450² / 46 + 4230² / 52)² / ((3450² / 46)² / (46 - 1) + (4230² / 52)² / (52 - 1))

= (119023.913 + 180714.2308)² / ((119023.913)² / 45 + (180714.2308)² / 51)

= 113242.1436

The degrees of freedom are approximately 113242.

Now, we need to find the p-value associated with the test statistic and degrees of freedom.

We can use a t-distribution table to look up the p-value.

Since the test is one-tailed and the test statistic is negative, we will look up the p-value in the left tail of the t-distribution with the given degrees of freedom.

Assuming the p-value is less than 0.0001, we can state that the p-value is approximately 0.0001.
