mass of chain = 134 kg

Step-by-step explanation:

a)  sin28 = 37/p             sin = opposite/hypotenuse

p = 37/sin28 = 78.8 m

b)  78.8 m  x 1.7 kg/m = 134 kg

Therefore, the final amount for an investment of $5,000 over 5 years at an annual interest rate of 6% if the interest is compounded quarterly is $6,734.27.

SI unit is defined as (P, R, and T) / 100.

SI stands for Straightforward Interest in this instance. P represents the principal (loaned or invested), and R represents the interest rate.

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

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

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

Here, we have:

P = $5,000

r = 6% = 0.06 (annual interest rate)

n = 4 (compounded quarterly)

t = 5 years

Plugging these values into the formula, we get:

A = 5000 (1 + 0.06/4)^(4*5)

A = 5000 (1.015)^20

A = 5000 (1.349858807)

A = $6,734.27 (rounded to the nearest cent)

Therefore, the final amount for an investment of $5,000 over 5 years at an annual interest rate of 6% if the interest is compounded quarterly is $6,734.27.

Step-by-step explanation:

Using Pythagoras Theorem, The height of the screen is approximately 27.18 inches.

Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.

We can use the Pythagorean theorem to solve this problem. Let's call the height of the screen "h". Then, according to the Pythagorean theorem, we have:

[tex]h^2 + 32^2 = 42^2[/tex]

Simplifying this equation, we get:

[tex]h^2 + 1024 = 1764[/tex]

Subtracting 1024 from both sides, we get:

[tex]h^2 = 740[/tex]

Taking the square root of both sides, we get:

[tex]h = \sqrt{(740)}[/tex]

Using a calculator to approximate the square root, we get:

h ≈ 27.18 inches

Hence, the height of the screen is approximately 27.18 inches.

The solutions to the equation z^2 = -361 are:

z = ±19i and z = ±19i*(-1)^k, k = 0 or 1.

To find all n complex solutions of the equation x^n = k, where k is a complex number, we can use the polar form of complex numbers. If we write k in polar form as k = re^(iθ), where r = |k| is the modulus of k and θ = arg(k) is the argument of k, then we can write x in polar form as x = ρe^(iφ), where ρ = |x| is the modulus of x and φ = arg(x) is the argument of x.

Substituting these polar forms into the equation x^n = k, we get:

(ρe^(iφ))^n = re^(iθ)

Taking the modulus of both sides, we get:

|ρ^n| = |r|

Since r is a complex number, its modulus is a positive real number, so we can write r = Re^(i0) in polar form, where R = |r|.

Substituting this into the equation above, we get:

|ρ^n| = R

Taking the argument of both sides, we get:

nφ = 0 + 2πk

where k is an integer. Solving for φ, we get:

φ = (2π*k) / n

Substituting this expression for φ back into the polar form of x, we get:

x = ρe^(i(2π*k)/n)

where ρ is a positive real number. This gives us n complex solutions for x, which are:

x = ρe^(i(2π*k)/n), k = 0, 1, 2, ..., n-1.

Now let's apply this method to solve the equation z^2 = -361.

Writing -361 in polar form, we have:

-361 = 361e^(iπ)

Taking the square root of both sides, we get:

z = ±sqrt(361)e^(iπ/2 + iπk)

where k = 0 or 1. Simplifying, we get:

z = ±19e^(i(π/2 + π*k))

So the solutions to the equation z^2 = -361 are:

z = ±19i and z = ±19i*(-1)^k, k = 0 or 1.

The following solutions with regard to resolving or simplifying the radii of the circular pond are given below.

Part A: 5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: 5 × 10 + 2√41 meters = 50 + 2√41 meters

Part C: The radius of Pond B is 10√2 meters.

Part D: the radius of Pond B is greater than the radius of Pond A.

Part A: The mistake is in Step 1. To simplify the square root of 164, we need to find its prime factors:

164 = 2 × 2 × 41

So, we can write:

√164 = √(2 × 2 × 41) = 2√41

Using this, we can rewrite Step 1 as:

5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: Using the corrected step from Part A, we can simplify the radius of Pond A as:

5 × 10 + 2√41 meters = 50 + 2√41 meters

So, the radius of Pond A is 50 + 2√41 meters.

Part C: The radius of Pond B is already simplified, so we don't need to do any additional steps. It is:

25√200/5 meters = 5√200 meters

We can simplify this further by finding the prime factorization of 200:

200 = 2 × 2 × 2 × 5 × 5

So, we can write:

√200 = √(2 × 2 × 2 × 5 × 5)

= 2 × 5√2

Using this, we can rewrite the expression for the radius of Pond B as:

5 × 2 × √2 meters

= 10√2 meters

Thus, the radius of Pond B is 10√2 meters.

Part D: We can compare the radii of the ponds using the original expressions by writing:

√164 < 25√200/5

Simplifying both sides:

2√41 < 10√2

Dividing both sides by 2:

√41 < 5√2

Squaring both sides (since both sides are positive):

41 < 25 × 2

41 < 50

So, the inequality is true. Therefore, the radius of Pond B is greater than the radius of Pond A.

The one real solution of the equation 6x^(2)+7x-h=0 can be expressed in terms of equality as h = -49/24 using discriminant formula.

To find all values of h for which the quadratic equation 6x^(2)+7x-h=0 has one real solution, we need to use the discriminant formula. The discriminant formula is given by:

D = b^(2) - 4ac

Where a, b, and c are the coefficients of the quadratic equation. In this case, a = 6, b = 7, and c = -h. Plugging these values into the formula, we get:

D = 7^(2) - 4(6)(-h)

D = 49 + 24h

For the quadratic equation to have one real solution, the discriminant must be equal to 0. Therefore, we can set D = 0 and solve for h:

49 + 24h = 0

24h = -49

h = -49/24

Therefore, the value of h for which the quadratic equation has one real solution is h = -49/24. We can write this as an equality:

For the given observations 48, 12, 11, 45, 48, 48, 43, 32, the values are -

Mean = 37.5 , Median = 44, and Mode = 48

The median is the best measure for the data.

What is mean?

In statistics, in addition to the mode and median, the mean is one of the metrics of central tendency. Simply put, the mean is the average of the values in the given collection. It indicates that values in a particular data collection are distributed equally. The three most frequently employed metrics of central tendency are the mean, median, and mode.

To find the measure that best represents the given data, we can calculate the mean, median, and mode and choose the measure that gives us the most representative value.

Mean -

To find the mean of the data, we add up all the values and divide by the total number of values -

Mean = (48 + 12 + 11 + 45 + 48 + 48 + 43 + 32) / 8 = 37.5

Median -

To find the median of the data, we arrange the values in order from smallest to largest and then find the middle value.

If there are an even number of values, we take the average of the two middle values.

11, 12, 32, 43, 45, 48, 48, 48

There are eight values in the data set, so the median is -

(43 + 45) / 2

88 / 2

44

Mode -

To find the mode of the data, we look for the value that occurs most frequently.

In this case, 48 occurs three times, which is more than any other value, so the mode is 48.

Conclusion:

In this data set, the mean is 37.5, the median is 44, and the mode is 48. Since the data set has some values that are higher than the others, such as 48 occurring three times, the mean may be influenced by these outliers.

In this case, the median is a better measure of central tendency because it is not influenced by outliers.

Therefore, the median is the measure that best represents the data.

We can use the fact that 32 is equal to 2 raised to the power of 5:

32 = 2^5

Substituting this into the equation gives:

16^x = 2^5

We can then rewrite 16 as 2^4, since 16 is equal to 2 raised to the power of 4:

(2^4)^x = 2^5

Simplifying the left side of the equation gives:

2^(4x) = 2^5

Now we can see that the bases of both sides of the equation are equal, so we can set the exponents equal to each other:

4x = 5

Dividing both sides by 4 gives:

x = 5/4

Therefore, the solution to the equation 16^x = 32 is x = 5/4.

Answer:

See below.

Step-by-step explanation:

We are asked to identify BC and AC.

Before we start, we should know that this triangle has a center called a Centroid.

A Centroid is a point that is formed by 3 concurrent medians.

A Median is a line segment that connects the vertex of a triangle to the midpoint of the opposite side.

The top part of a Median is 2/3 of the entire line segment. The bottom part of a Median is 1/3 of the entire line segment.

Using the information from above, we can identify that AB (10) is 2/3 of AC, and that BC is 1/3 of AC.

Divide 10 by [tex]\frac{2}{3}[/tex] to find AC.

[tex]10 \div ( \frac{2}{3} )=15 \ (AC)[/tex]

Since we know AC, we can now find BC by simply subtracting AC - AB.

Therefore, AC = 15; BC = 5.

After eight leaps, there is a 0.3828 percent chance that the bug will still be within three units of where it started.

a. To return to the origin after eight jumps, the bug must take an equal number of left and right jumps. Since there are [tex]2^8=256[/tex] possible sequences of eight left/right jumps, we need to count how many of these sequences have an equal number of left and right jumps. To do this, we can use the binomial coefficient:

[tex]C(8,4) = 8! / (4! * 4!) = 70[/tex]

This counts the number of ways to choose 4 out of 8 jumps to be leftward, with the other 4 jumps being rightward. Therefore, the probability of returning to the origin after eight jumps is:

[tex]P(return to origin) = 70 / 256 = 0.2734[/tex]

b. To be within three units of the origin after eight jumps, the bug must take at most three more rightward than leftward jumps or three more leftward than rightward jumps. We can compute the probabilities of each of these cases separately and add them up. Let's first consider the case where there are three more rightward jumps than leftward jumps. To count the number of such sequences, we can choose three out of the eight jumps to be leftward, with the other five jumps being rightward. Therefore, the probability of this case is:

P(3 more rightward) = C(8,3) / 256 = 0.1094

Similarly, the probability of having three more leftward jumps than rightward jumps is also 0.1094. To count the number of sequences where there are two more rightward jumps than leftward jumps, we can choose two out of the eight jumps to be leftward, with the other six jumps being rightward. There are also C(8,2) sequences with two more leftward jumps than rightward jumps. Therefore, the probability of being within three units of the origin after eight jumps is:

[tex]P(within 3 units) = 2 * 0.1094 + 2 * C(8,2) / 256 = 0.3828[/tex]

Therefore, the probability that the bug is within three units of the point of departure after eight jumps is 0.3828.

A regular polygon is one that has an equal number of sides and angles. Each vertex of a regular polygon is located on a shared circle known as the circumscribed circle or circumcircle. A circumscribed circle or circumcircle of the polygon, on the other hand, is any circle that goes through every vertex of the polygon. The circumradius of the polygon is the circumference of the circle. The circumradius is the distance from the centre to any vertex of a regular polygon with n sides, and the circumcircle's centre coincides with the polygon's centre.

Given that, the hexagon is regular, angle AOB is 60 degrees.

The side AB is given as 8cm.

Using trigonometric functions we have:

h = r * cos(30 degrees) = (√(3)/2) * r.

Now using the Pythagoras theorem:

OB² = AB² - h².

Substituting the value of h:

OB² = 8² - (√(3)/2)² * r².

OB² = 64 - (3/4) * r².

OB = √(64 - (3/4) * r²).

Here, OB is equal to the radius of the circle.

r = √(64 - (3/4) * r²) = 5.861 cm.
