Answer: 880 Trees

Step-by-step explanation:

To determine the number of trees that can be planted on 2 miles of streets, we need to convert the distance from miles to feet and then divide it by the spacing between each tree.

1 mile is equal to 5,280 feet. Therefore, 2 miles would be 2 * 5,280 = 10,560 feet.

If each tree is planted 12 feet apart, we can calculate the number of trees by dividing the total distance by the spacing between each tree:

Number of trees = Total distance / Spacing between each tree

Number of trees = 10,560 feet / 12 feet

Number of trees = 880

Therefore, they can plant 880 trees on 2 miles of streets, assuming each tree is planted 12 feet apart.

The sorting algorithms that are not comparison based are counting sort, bucket sort, and radix sort.

Counting sort works by counting the number of occurrences of each element in an array and then using this information to determine the position of each element in the sorted array.

Bucket sort works by dividing the array into a number of smaller arrays, called buckets, and then sorting each of these smaller arrays separately.

Radix sort works by sorting the elements of an array based on the individual digits of each element, starting with the least significant digit and working up to the most significant digit.

These algorithms do not rely on comparisons between elements, which is why they are not considered comparison based.

Given:

prtion D is the correct answer.

Answer:

C: y + 3 = 1/4(x + 4)

Step-by-step explanation:

Perpendicular to a given line means opposite inverse of the slope...

Equation of line is: y = -4x - 3

slope in above equation is -4, perpendicular would be 1/4

Perpendicular equation of a line through P(-4, -3):

y = mx + b

-3 = 1/4(-4) + b

-3 = -1 + b

b = -2

Use perpendicular slope and the b from above to form the perpendicular equation of line:

y = 1/4x - 2

Check:

(-3) = 1/4(-4) - 2

-3 = -1 - 2

-3 = -3

Answer:

x = 2/3

Step-by-step explanation:

cross multiply

-9(x-4) = 10(3x+1)

and then solve the equation

-9x + 36 = 30x + 10

36 = 39x + 10

26 = 39x

x = 2/3

The mean cycle time for the trucks hauling concrete to a highway construction site is 60 minutes, and the variance of the cycle times is 100/3 minutes squared.

The cycle time for the trucks hauling concrete is uniformly distributed over the interval 50 to 70 minutes. This means that any value within the interval has an equal chance of being the cycle time for the trucks. The probability density function (PDF) for a uniform distribution is given by:

f(x) = 1/(b-a), for a ≤ x ≤ b

where a = 50 minutes (the lower limit of the interval) and b = 70 minutes (the upper limit of the interval).

To find the mean of the cycle times, we can use the formula:

mean = (a + b)/2

Substituting the values of a and b, we get:

mean = (50 + 70)/2 = 60

Therefore, the mean cycle time for the trucks hauling concrete is 60 minutes.

To find the variance of the cycle times, we can use the formula:

variance = (b - a)² / 12

Substituting the values of a and b, we get:

variance = (70 - 50)² / 12 = 100/3

Therefore, the variance of the cycle times for the trucks hauling concrete is 100/3 minutes squared.

Therefore, the forecast function g(h) is given by: g(h) = Xn + 0.8(Xn+1 - Xn) - 0.25(Xn+2 - Xn+1) for h > 0.

To determine the forecast function g(h) for an ARIMA(2,1,0) process, we need to find the values of Xn+h for each h > 0.

The ARIMA(2,1,0) model can be represented as (1 - 0.8B + 0.25B^2)∇Xt = Zt, where ∇Xt represents the differenced series and Zt is white noise with mean 0 and variance 1.

To forecast the future values, we need to solve the difference equation for ∇Xn+h. Let's denote the difference operator as Δ = (1 - B) and rewrite the model as:

Δ(1 - 0.8B + 0.25B^2)Xt = Zt

Expanding the expression, we have:

Xn+h - Xn - 0.8(Xn+1 - Xn) + 0.25(Xn+2 - Xn+1) = Zn+h

Rearranging the equation, we get:

Xn+h = Xn + 0.8(Xn+1 - Xn) - 0.25(Xn+2 - Xn+1) + Zn+h

Therefore, the forecast function g(h) is given by:

g(h) = Xn + 0.8(Xn+1 - Xn) - 0.25(Xn+2 - Xn+1) for h > 0.

Answer:

Length = 7cm, Width = 15cm

Step-by-step explanation:

Length = p

Width = 3(p-2)

          = 3p-6

Perimeter = length + width + length + width

                = p + 3p-6 + p + 3p-6

                = 8p-12

8p - 12 = 44

Isolate 8p.

8p = 44+12

    = 56

Find p.

p = 56 ÷ 8

p = 7

Length = 7cm

Width = 3(7)-6

          = 21-6

          = 15cm

The Cartesian coordinates for the polar coordinate (9, (11π)/6) are x = (9√3)/2 and y = 9/2.

To convert a polar coordinate to Cartesian coordinates, we use the formulas:

x = r * cos(theta)

y = r * sin(theta)

Given the polar coordinate (9, (11π)/6), where r = 9 and θ = (11π)/6, we can substitute these values into the formulas:

x = 9 * cos((11π)/6)

y = 9 * sin((11π)/6)

To simplify, let's recall the values of cosine and sine for (11π)/6. In the fourth quadrant, the reference angle for (11π)/6 is π/6. We know that cos(π/6) = √3/2 and sin(π/6) = 1/2.

Substituting these values into the formulas:

x = 9 * (√3/2)

y = 9 * (1/2)

Simplifying further:

x = (9√3)/2

y = 9/2

Therefore, the Cartesian coordinates for the polar coordinate (9, (11π)/6) are x = (9√3)/2 and y = 9/2.

from the question, we have the following parameters that can be used in our computation:

f(x) = 2x³ + 6x - 1/x + 3eˣ - sin(x)

The derivative of the functions can be calculated using the first principle which states that

Using the above as a guide, we have the following:

f'(x) = 6x² + 6 - ln(x) + 3eˣ - cos(x)

Step-by-step explanation:

the probability that a top-selling red and voss tire wears out before 80,000 miles is about 2.56%.

The student question asks about the probability that a top-selling red and voss tire, rated for 80,000 miles, wears out before reaching 80,000 miles. The tire's lifespan follows a normal distribution with a mean of 94,000 miles and a standard deviation of 7200 miles.
To find the probability, we need to calculate the z-score first. The z-score is a measure of how many standard deviations away from the mean a particular value is. We can use the following formula to calculate the z-score:
z = (X - μ) / σ
where X is the value (in this case, 80,000 miles), μ is the mean (94,000 miles), and σ is the standard deviation (7200 miles).

Calculate the z-score:
z = (80,000 - 94,000) / 7200
z = -14,000 / 7200
z ≈ -1.944
The z-score is approximately -1.944, which means the tire wearing out at 80,000 miles is about 1.944 standard deviations below the mean.
Find the probability:
Now, we can use the z-score to find the probability. We can look up the z-score in a standard normal distribution table or use a calculator with a built-in function for this purpose.
Using a standard normal distribution table or calculator, we find that the probability corresponding to a z-score of -1.944 is approximately 0.0256 or 2.56%.

The value of a computer depreciates by $25 each month. Given that the computer initially costs $1300, we need to determine the value of the computer after t months.

To find the value of the computer after t months, we subtract the total depreciation from the initial cost. The total depreciation can be calculated by multiplying the depreciation per month ($25) by the number of months (t). Therefore, the value V of the computer after t months is given by V = $1300 - $25t.

This equation represents a linear relationship between the value of the computer and the number of months. Each month, the value decreases by $25, resulting in a straight line with a negative slope. The value of the computer decreases linearly over time as the depreciation accumulates. By substituting the appropriate value of t into the equation, we can find the specific value of the computer after a certain number of months.
