Answers

A computation time expression ~ n, of means that the computation time increases in proportion to the size of the input.

This presents a computational complexity of O(n). Here 'O' stands for 'Big O Notation' and is used to denote an upper bound on the computational complexity of the algorithm.

That's, the algorithm's computational complexity is straightforwardly corresponding to the measure of the input information.

This shows that as the input estimate increments, the computational time will increment at the same rate.

 Linear time complexity is considered to be very efficient, and many algorithms aim to achieve this level of complexity. This is a relatively efficient computational complexity and is common in algorithms that require only one pass through the input data.

Let f be the function defined by f(x)=xlnx for x>0. On what open interval is f decreasing?

Answers

The function f(x) = xlnx is decreasing on the open interval (0, e^-1).

To find the interval on which the function f(x) = xlnx is decreasing, we need to find the intervals where the first derivative f'(x) is negative.

Using the product rule of differentiation, we can find the first derivative of f(x) as

f'(x) = x × (1/x) + ln(x) × 1 = 1 + ln(x)

Now, we need to find the values of x where f'(x) < 0

1 + ln(x) < 0

ln(x) < -1

x < e^-1

Therefore, f(x) is decreasing on the interval (0, e^-1).

Note that we exclude x = 0 from the interval because the function is not defined for x ≤ 0.

Find the are length of An Leave your answer in terms of it and round to the nearest hundredths

Answers

The exact length of arc AB is π feet. To round to the nearest hundredths, we get:

AB ≈ 3.14 feet

What is a circle?

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

we can use the central angle and the fact that a full circle has a central angle of 360° to calculate the fraction of the circumference that AB represents.

Since the central angle, APB is 45°, we can calculate the fraction of the circumference that AB represents as:

45°/360° = 1/8

Therefore, AB represents 1/8 of the circumference of the circle.

If we let C be the circumference of the circle, then the length of AB can be calculated as:

AB = (1/8) * C

Since we do not know the value of C, we cannot calculate the exact length of AB. However, we can leave our answer in terms of π as:

AB = (1/8) * π * d

where d is the diameter of the circle.

If the diameter of the circle is 8ft, then the radius (r) is half of that, or 4ft. We can now use this value to find the exact length of AB.

The circumference (C) of the circle can be found using the formula:

C = 2πr

where π is the constant pi.

Plugging in the given value of the radius, we get:

C = 2π(4ft) = 8πft

Therefore, the exact length of AB is:

AB = (1/8) * C = (1/8) * 8π ft = π ft

Hence, the exact length of arc AB is π feet. To round to the nearest hundredths, we get:

AB ≈ 3.14 feet

If the reentry angle is 6.5°, what is x?



WORTH A LOt OF POINTS !!

Answers

Given the above conditions in the word problem above, x is also equal to 6.5°.

What is the explanation for the above response?

The angle x is the angle between this perpendicular line and the Earth's surface. It is also equal to the angle between the tangent line and the horizontal axis.

Since the reentry angle is 6.5°, we know that the tangent line makes an angle of 6.5° with the horizontal axis. We also know that the tangent line and the perpendicular line form a right angle, so the angle between the perpendicular line and the horizontal axis is 90° - 6.5° = 83.5°.

Finally, we can subtract this angle from 90° to find x:

x = 90° - 83.5° = 6.5°

For the hypothesis test h0:μ=8 against h1:μ>8 with variance unknown and n=10, find the best approximation for the p-value for the test statistic t0=2. 155

Answers

The best approximation for the p-value for the test statistic t0 = 2.155 is 0.032.

To find the best approximation for the p-value for the hypothesis test with null hypothesis H0: μ=8 and alternative hypothesis H1: μ>8, with variance unknown and n=10, and a test statistic t0=2.155, we need to use the t-distribution with degrees of freedom (df) equal to n-1 = 10-1 = 9.

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed one, assuming the null hypothesis is true. Since this is a one-tailed test with the alternative hypothesis in the form of μ>8, the p-value corresponds to the area in the right tail of the t-distribution.

Using a t-table or calculator with the t-distribution, we can find the probability of obtaining a t-value as large as 2.155 or larger with 9 degrees of freedom. This probability is approximately 0.032. Therefore, the best approximation for the p-value for this hypothesis test is 0.032.

We can interpret this result as follows: if the null hypothesis is true (i.e., if the population mean is 8), the probability of obtaining a sample mean as extreme or more extreme than the observed one (i.e., greater than 8.215) is 0.032. Since this probability is relatively small, we may reject the null hypothesis in favor of the alternative hypothesis at a significance level of 0.05 or smaller.

Answers

If the diameter of circular-garden is 18 feet, then it will cost Randy an amount of $85.50 to buy edges for his garden.

The "Circumference" of circle is defined as the "total-length" of the boundary or the outer edge of the circle.

The circumference formula is : Circumference = π × Diameter,

The "diameter" of garden is = 18-feet,

So, Circumference = 3.14 × 18 = 56.52 feet,

Since, Randy needs to buy plastic-edging to cover the entire circumference of garden, he needs to buy 56.52 feet of edging.

We know that, Randy can only buy edging in whole-foot amounts,

So, rounding up to the nearest whole foot, we get 57 feet,

The cost of edging is = $1.50 per foot,

So, "total-cost" for Randy to buy edging for his garden is,

⇒ Total Cost = (Cost per foot) × (Number of feet),

⇒ $1.50 × 57,

⇒ $85.50

Therefore, it will cost Randy $85.50 to buy edging for his circular garden.

The z-score of a car that is 6 years old is  -0.625.

To find the z-score of a car that is 6 years old, we can use the formula:

z = (x - μ) / σ

where x is the value we are interested in (in this case, 6 years old), μ is the mean of the distribution (8 years), and σ is the standard deviation (3.2 years).

Plugging in the values, we get:

z = (6 - 8) / 3.2 = -0.625

Therefore, the z-score of a car that is 6 years old is -0.625. This indicates that the car is 0.625 standard deviations below the mean age of cars driven by employees at the company. Since the distribution is normal, we can use this z-score to find the probability of finding a car with an age of 6 years or less, using a z-table or a calculator.

What does the calculation's mean mean?

By dividing the sum of the numbers by the total number of numbers, the mean, or average, of the given numbers is determined. Mean is equal to (Sum of all Observations / Total Observations).

We must sum up all the values and divide by the total number of values to determine the mean of the data in the dot plot.

The first step is to count the dots for each value:

3 has 3 dots

4 has 5 dots

5 has 6 dots

6 has 8 dots

7 has 5 dots

8 has 3 dots

Then, multiplying each value by the quantity of dots associated with it, we must total up all the products:

(3 x 3) + (4 x 5) + (5 x 6) + (6 x 8) + (7 x 5) + (8 x 3) = 3 + 20 + 30 + 48 + 35 + 24 = 160

Last but not least, we must divide the entire number of values—i.e., dots—by the sum:

An amount of R6000 is made up of R100 and R50 notes. There are 4 times as many R50 notes as there are R100 notes. how many notes are there?

Answers

Answer:

There are 20 R100 notes and 80 R50 notes.

Step-by-step explanation:

Let's call the number of R100 notes "x" and the number of R50 notes "4x" (since there are 4 times as many R50 notes as R100 notes).

We can set up an equation to represent the total value of the notes:

100x + 50(4x) = 6000

Simplifying:

100x + 200x = 6000

300x = 6000

x = 20

So there are 20 R100 notes and 4 times as many R50 notes:

4x = 4(20) = 80

Therefore, there are 20 R100 notes and 80 R50 notes.

Where is the turning point for f(x+4)+5

Answers

The answer of the given question based on the function is ,  the turning point of the function f(x+4)+5 is at the point (-4, -5).

What is Function?

In mathematics, a function is a rule that assigns each input value (or argument) in a set to a unique output value in another set. In other words, it is a relationship between two sets of numbers, where each input value produces exactly one output value. Functions are usually represented using function notation, where the name of the function is followed by the input value in parentheses.

To find the turning point of the function f(x+4)+5, we need to first rewrite the function in vertex form, which is given by:

f(x) = a(x-h)² + k

where (h, k) is vertex of parabola.

To do this, we can start by completing the square:

f(x+4) + 5 = a(x+4-h)² + k

f(x+4) = a(x+4-h)² + k - 5

To complete the square, we need to add and subtract (4-h)²/4a inside the parentheses:

f(x+4) = a(x+4-h)² + k - 5 + (4-h)²/4a - (4-h)²/4a

f(x+4) = a(x+4-h)² + (4-h)²/4a + (4a*k-20a)/4a

Now the function is in vertex form:

f(x+4) = a(x+4-h)² + (4-h)²/4a + (4a*k-20a)/4a

The vertex of the parabola is at (h, k), so in this case, the vertex is at (-4, -5).

Therefore, the turning point of the function f(x+4)+5 is at the point (-4, -5).

The two solutions that satisfy the equation 3x^2 + 2x = 6 when rounded to two decimal places are x = 1.12 and x = −1.79. So, correct option is A.

To solve for x in the equation 3x^2 + 2x = 6, we need to rearrange the terms and use the quadratic formula:

3x^2 + 2x - 6 = 0 (subtract 6 from both sides)

x = (-b ± √(b^2 - 4ac)) / 2a (quadratic formula)

In this equation, a = 3, b = 2, and c = -6, so we can substitute those values into the quadratic formula:

x = (-2 ± √(2^2 - 4(3)(-6))) / 2(3)

x = (-2 ± √(4 + 72)) / 6

x = (-2 ± √(76)) / 6

Simplifying this expression, we get:

x = (-2 ± 2√(19)) / 6

x = (-1 ± √(19)) / 3

Rounding these solutions to two decimal places, we get:

Answers

Carbon 14 has a half-life of 5,600 years, which means that after 5,600 years, half of the initial amount of Carbon 14 will decay. Therefore, we can use the following formula to find the amount of Carbon 14 that was present 11,200 years ago:

A = A0 * (1/2)^(t/T)

where:

A0 = initial amount of Carbon 14

A = amount of Carbon 14 remaining after time t

t = time elapsed since the initial amount was present

T = half-life of Carbon 14

How many grams did it contain 11,200 years ago?

We know that the fossil contains 3 g of Carbon 14, which is the amount remaining after 11,200 years. We want to find the initial amount, A0.

Let's plug in the values we have into the formula and solve for A0:

3 g = A0 * (1/2)^(11,200/5,600)

3 g = A0 * (1/2)^2

3 g = A0 * 1/4

(y2 - y1) / (x2 - x1)

(y2 - y1) =(2/3 - 6) =-17/3

(x2 - x1) = (2 - (-4))= 6

Hence slope = -17/18

Here the In starting number of chess sets = 18

Ordered number of chess set cases = 3

In each case number of chess sets= 15

Then total number of ordered chess sets = 3*15 = 45.

Now total number of chess set in chess club = 45+18 = 64.

The number of teacher = 4.

Then expression is ,

The number of chess sets each of the 4 teachers should get = 63/4 = 15 [tex]\frac{3}{4}[/tex]

Remaining set = 3.

Hence the greatest number of chess sets each of the 4 teachers should get is 15.
