Determine the length of a chord whose central angle is 80° in a circle with a radius of 4 centimeters. Question 9 options: 3.94 cm 2.57 cm 5.14 cm 7.88 cm

Answers

Answer 1

The length of the chord whose central angle is 80° in a circle with a radius of 4 centimeters is 5.14 cm using the law of cosines.

Given that,

Central angle of a chord = 80°

Radius of the circle = 4 centimeters

There will be a triangle formed by the chord and the two radius.

Let a be the length of the chord.

Using the law of cosines,

a² = 4² + 4² - (2 × 4 × 4) cos (80°)

a² = 16 + 16 - 32 cos (80°)

a² = 32 - 32 cos (80°)

a² = 26.4433

a = 5.14

Hence the length of the chord is 5.14 cm.

find dy/dx of y= ln(1-x^2/1+x^2)

The derivative of y with respect to x is:

[tex]dy/dx = -4x / (1 - x^4)[/tex]

How to find derivative ?

The chain rule and the quotient rule must be utilized in order to determine the derivative of y with respect to x.:

First, we can rewrite y as follows:

[tex]y = ln[(1 - x^2)/(1 + x^2)][/tex]

Let's define two functions:

[tex]u = 1 - x^2[/tex]

[tex]v = 1 + x^2[/tex]

Then, y can be rewritten in terms of u and v as:

y = ln(u/v)

Now, we can use the chain rule to find the derivative of y with respect to u and v, respectively:

[tex]dy/du = 1/u\\dy/dv = -1/v[/tex]

Using the quotient rule, we can find the derivative of y with respect to x:

[tex]dy/dx = (dy/du) * (du/dx) + (dy/dv) * (dv/dx)[/tex]

[tex]du/dx = -2x\\dv/dx = 2x[/tex]

Substituting in the values we get:

[tex]dy/dx = (dy/du) * (du/dx) + (dy/dv) * (dv/dx)\\= (1/u) * (-2x) + (-1/v) * (2x)\\= -2x/(1 - x^2) - 2x/(1 + x^2)\\= -4x / (1 - x^4)[/tex]

Therefore, the derivative of y with respect to x is:

When a baseball is thrown upward, its height h, in feet, is the function of time t, in seconds. If this function is described by the formula h(t)=-16t^2+24t+5, what is the maximum height of the baseball reaches?

Answers

Answer:

the maximal height is 14.75 units of distance.

Step-by-step explanation:

We want to find the maximum height of the function

h(t) = -16*t^2 + 24*t + 5

In order to find the maximum, we need to find the value of t where the derivate of h(t) is equal to zero, then we evaluate our original function in that time.

The derivate of h(t) (or the vertical velocity) is:

h'(t) = 2*(-16)*t + 24 = -32*t + 24

we want to find the value of such:

0 = -32*t +24

32*t = 24

t = 24/32 = 0.75

Now we evaluate our height function in that value.

h(0.75) = -16*0.75^2 + 25*0.75 + 5 = 14.75 units



The maximum height of the baseball can be found by determining the vertex of the parabolic function h(t) = -16t^2 + 24t + 5.

The vertex of a parabola in the form of y = ax^2 + bx + c is given by the coordinates (-b/2a, c - b^2/4a).

In this case, a = -16, b = 24, and c = 5.

Therefore, the vertex of the parabola is at t = -b/2a = -24/(2*-16) = 0.75 seconds.

To find the maximum height, we substitute t = 0.75 into the equation for h(t):

h(0.75) = -16(0.75)^2 + 24(0.75) + 5 = 11.5 feet.

Therefore, the maximum height reached by the baseball is 11.5 feet.

what is the best measure of sensors to use in the set of data below 12, 8, 15, 45, 7, 13 mean, median, mean or median, mode?​

Answers

Answer:

The best measure of central tendency to use in a set of data depends on the characteristics of the data and the specific objective of the analysis. Let's examine the given data set: 12, 8, 15, 45, 7, 13.

Mean: The mean, also known as the average, is calculated by summing up all the values in the data set and dividing by the total number of values. The mean is sensitive to extreme values and can be influenced by outliers. In this case, the mean is calculated as (12 + 8 + 15 + 45 + 7 + 13) / 6 = 100 / 6 ≈ 16.67.

Median: The median is the middle value in a data set when the values are arranged in ascending or descending order. The median is not affected by extreme values and is a good measure to use when there are outliers or when the data is not symmetrically distributed. In this case, when the data set is arranged in ascending order, the median is 13, as it is the middle value.

Mode: The mode is the value that appears most frequently in a data set. It is a useful measure when we want to identify the most common value in the data set. In this case, the mode is not applicable as there are no repeated values in the data set.

Based on the characteristics of the given data set, the median is a good measure to use as it is not affected by extreme values and provides a central value that represents the middle of the data set. The mean may be influenced by the outlier value of 45, and the mode is not applicable in this case. So, the best measure of central tendency to use in this data set would be the median.

Answers

Based on the data displayed in the box plots, Mr. Simpson's class lost the most pencils overall. This can be determined by looking at the median value for each class, which is represented by the line inside the box. The median value for Mr. Simpson's class is 14.5 pencils, while the median value for Mr. Johnson's class is 11 pencils. Therefore, Mr. Simpson's class had a higher median number of pencils lost.

The spread of the data can also be considered, but it does not necessarily indicate which class lost the most pencils overall. Mr. Simpson's class has a narrower spread than Mr. Johnson's class, but this only means that the data in Mr. Simpson's class is more consistent, not that they lost fewer pencils overall.

Therefore, the answer is: Mr. Simpson's class; it has a larger median value 14.5 pencils.

The Indian cricket team won 50% of the matches played in the first two weeks of the
NatWest series in Australia. However, at the end of the series its success rate was 75%. If
the team had played 6 matches in the first two weeks and they then won all the matches
they played after the first two weeks, how many matches did they play after the first
two weeks?

Answers

Answer:

the Indian cricket team played 13 matches after the first two weeks.

Step-by-step explanation:

Let's assume that the Indian cricket team played x matches after the first two weeks.

We know that the team won 50% of the matches played in the first two weeks. So, out of the 6 matches played in the first two weeks, they won 0.5*6 = 3 matches.

We also know that at the end of the series, their success rate was 75%. This means that out of the total number of matches played in the entire series, they won 75% of them. Let's say the total number of matches played in the series is y. Then, we can write:

Number of matches won = 0.5*6 + x (matches won in the first two weeks + matches won after the first two weeks)

Total number of matches played = 6 + x (matches played in the first two weeks + matches played after the first two weeks)

According to the given information, the success rate at the end of the series was 75%. So we can write:

Number of matches won / Total number of matches played = 75/100

Substituting the values, we get:

(0.5*6 + x) / (6 + x) = 75/100

Simplifying this equation, we get:

12 + 4x = 25 + 3x

x = 13

Therefore, the Indian cricket team played 13 matches after the first two weeks.

A rectangular storage container with an open top is to have a volume of 20 cubic meters. The length of its base is twice the width. Material for the base costs 20 dollars per square meter. Material for the sides costs 3 dollars per square meter. Find the cost of materials for the cheapest such container.

Answers

The cost of the materials for the cheapest container is when width = 1.5 m

Given data ,

Let's use "w" metres to represent the rectangular storage container's width. The length would be "2w" metres since the base's length is twice as long as its width.

The container's height is indicated by the letter "h" metres.

Volume is determined by the following formula:

20 = (2w)(w)(h) 20 = 2w²h

The equation may be rearranged to represent "h" in terms of "w":

h = 20 / (2w²)

The container's "w" and "h" surface area is the next item to discuss. The surface area would be made up of the base and the four sides as the container has an open top.

We are given that the cost of material for the base is $20 per square meter and the cost of material for the sides is $3 per square meter

Cost of base material = 20 x 2w² = 40w² dollars

Cost of side material = 3 x 4wh = 12wh dollars

Total cost of material = Cost of base material + Cost of side material = 40w² + 12wh dollars

Now we can substitute the expression for "h" that we derived earlier:

Total cost of material = 40w^2 + 12w(20 / (2w²)) = 40w² + 120 / w

To find the value of "w" that minimizes the cost of material, we can take the derivative of the total cost of material with respect to "w" and set it equal to zero, then solve for "w":

d/dw (40w² + 120 / w) = 0

80w - 120 / w² = 0

On multiplying by w² on both sides , we get

80w = 120

Divide by 80 on both sides , we get

w = 3/4 m

Hence , the width of the rectangular box is w = 1.5 meter

lim[(5e^x-5e^(x+h))/3h]=(5/3)lim[(e^x-(e^x)(e^h))/h]=(5/3)e^xlim[(1-e^h))/h]=

-(5/3)e^xlim[(e^h-1))/h]=-(5/3)e^x as h approaches to 0.

how long will it take $5000 to grow to $6000 at an annual rate of 9% compounded monthly

Answers

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:
A = the amount of money after t years
P = the principal amount (the initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years

We know that P = $5000, A = $6000, r = 0.09 (9%), and n = 12 (since interest is compounded monthly). We can solve for t algebraically:

A = P(1 + r/n)^(nt)
$6000 = $5000(1 + 0.09/12)^(12t)
$6000/$5000 = (1 + 0.09/12)^(12t)
1.2 = (1.0075)^(12t)
log(1.2) = log(1.0075)^(12t)
log(1.2) = 12t * log(1.0075)
t = log(1.2) / (12 * log(1.0075))
t ≈ 4.58

Therefore, it will take about 4.58 years (or about 55 months) for $5000 to grow to $6000 at an annual rate of 9% compounded monthly.
To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:
A = the amount of money in the account after t years
P = the principal amount (the initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years

In this case, we want to find the time it takes for an investment of $5000 to grow to $6000 at an annual rate of 9% compounded monthly. So we have:

P = $5000
A = $6000
r = 0.09 (9% annual interest rate)
n = 12 (compounded monthly)

We want to solve for t, the number of years. So we can rearrange the formula to solve for t:

t = (log(A/P)) / (n * log(1 + r/n))

Substituting the values we have:

t = (log(6000/5000)) / (12 * log(1 + 0.09/12))

Simplifying:

t = 3.10 years (rounded to two decimal places)

Therefore, it will take approximately 3.10 years (or about 37 months) for an investment of $5000 to grow to $6000 at an annual rate of 9% compounded monthly.

How do I find the squareroot?

Answers

Answer:

Step-by-step explanation:

Factoring a square root means that you are finding the closest numbers that multiply together. The easiest square roots are ones that factor directly into squares, such as √100, but more complicated ones involve several square roots, such as √225. Here are the steps to finding the square root using factoring:

   1. Find the factors. Factors are the numbers you multiply to find the total under the square root symbol. For √100, the factors would be √(10 x 10). The factors of √225 would be √(25 x 9).

   2. Separate the factors into their own square roots. Because both factors of √100 are 10, the square root of 100 is 10. For √225, you would separate the factors under their own square root signs, so the formula would be √25 x √9.

  3.  Solve for the individual squares. Next, you would find the squares of each of the individual factors. √25 = 5 and √9 = 3. The remaining formula will look like 5 x 3.

   4. Finish solving the equation. Now that you know what the simplified squares are, you will find that 5 x 3 = 15. So, √225 = 15.

Hope that helps!

What is Probability?

Probability is a fundamental concept that gauges the plausibility of an event taking place. It is expressed numerically within the range of 0 to 1, with values corresponding to complete impossibility and absolute certainty respectively.

When probability values take on an exact midpoint value such as 0.5, they indicate equal probabilities for both possible outcomes. Experts use probability models before making significant decisions in fields such as science, engineering, finance, and speculative markets like gambling.

The study of these apprehension methods and their application form the foundation of probability theory, which helps analyze chance events' rules and guidelines.
