Step-by-step explanation:

To differentiate the function f(x) = 1/x^3, we can use the power rule of differentiation. Here's the step-by-step process:

Write the function: f(x) = 1/x^3.

Apply the power rule: For a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Differentiate the function: In our case, n = -3, so the derivative is:

f'(x) = -3 * x^(-3-1) = -3 * x^(-4) = -3/x^4.

Therefore, the derivative of the function f(x) = 1/x^3 is f'(x) = -3/x^4.

Step-by-step explanation:

use SOH CAH TOA to remember sin cos and tan functions

Sin = oppostive/hypotenuse
Cos = adjacent/hypotenuse
Tan = opposite/adjacent

22. cos(x) = b/c
24. sin(x) = 2/2sqrt(17) = 1/sqrt(17)
26. tan(x) = 2/8 = 1/4

28. cos(y) = 2/2sqrt(17) = 1/sqrt(17)
30. sin(30)
in a 30 60 90 triangle, the side opposite 30 is 1, the side opposite 60 is sqrt(3), the side opposite 90 is 2.
sin(30) = opposite/hypotenuse = 1/2/1 = 1/2
32.
in a 45 45 90 triangle, the side opposite 45 is 1, the side opposite 45 is 1, the side opposite 90 is sqrt2.

sin = opposite/hypotenuse = 1/sqrt(2)
34. cos(30) = sqrt(3)/2

36. tan(31) = AC/9 --> AC = 9tan(31) = 5.408

32.  \(\dfrac{\sqrt{2} }{2}\)

34.  \(\dfrac{\sqrt{3} }{2}\)

36. AC = 5.41 (nearest hundredth)

Step-by-step explanation:

Using trig ratios:

\(sin(\theta)=\dfrac{O}{H}\\\\\\cos(\theta)=\dfrac{A}{H}\\\\\\tan(\theta)=\dfrac{O}{A}\)

where \(\theta\) is the angle, O is the side opposite the angle, A is the side adjacent the angle, H is the hypotenuse of a right angle

22. \(cos(x)=\dfrac{b}{c}\)

24.  \(sin(x)=\dfrac{2}{2\sqrt{17} }=\dfrac{\sqrt{17} }{17}\)

26. \(tan(x)=\dfrac{2}{8}=\dfrac14\)

28. \(cos(y)=\dfrac{2}{2\sqrt{17} }=\dfrac{\sqrt{17} }{17}\dfrac{}{}\)

30. \(sin(30)=\dfrac12\)

32. \(sin(45)=\dfrac{\sqrt{2} }{2}\)

34. \(cos(30)=\dfrac{\sqrt{3} }{2}\)

36. \(tan(31)=\dfrac{AC}{9}\)

\(\implies AC=9tan(31)=5.41\) (nearest hundredth)

3(50 g) = 150 g

Answer:

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire

Step-by-step explanation:

Given that:

Perimeter of squared garden = 220m

As the perimeter is given, the length of the wire would be calculated with it.

The length of wire to fence with 1 round = 220 * 1 = 220m

The length of wire to fence with 2 rounds = 220 * 2 = 440m

The length of wire to fence with 3 rounds = 220 * 3 = 660m

Hence,

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire

No, any court case should not be based solely on probabilities as probability does not imply certainty.

Compute the probability of another couple being in that area with the same characteristics

CHARACTERISTIC ASSUMED PROBABILITY

Drives a yellow car 1 out of 12

Man over 6 feet tall 1 /10

Man wearing tennis shoes 1/4

Man with beard 1/11

Woman with blond hair 1/3

Woman with hair in a ponytail 1 /13

Women over 6 feet tall 1/100

We will use the multiplication rule as all the characteristics should be present in the couple.

The probability of another couple being in that area with the same characteristics is given as

P(Drives a yellow car) x P(Man with beard) x P(Woman with blond hair) x P(Woman with hair in a ponytail) x P(Woman over 6 feet tall) = 1/12 x 1/11 x 1/3 x 1/13 x 1/100 = 1/514800

The characteristics dependent on the sum of the probabilities is not equal to 1.

The assumption of independence would lead to use of the addition rule instead of the multiplication rule, and hence the probability would change (the probability would increase).

Alexander is utilizing a scale of 1 inch : 300 feet for his map.

The Alexander's triangle has a height of 4 inches in inches.

When comparing the initial dimensions as used by alexander, the scale of the map may be determined.

The scale is 1 inch: 300 feet since he used 10 inches to symbolize 3000 feet, this is gotten by diving both sides by 10

Using the scale factor 1 inch: 300 feet, the height of 1200 feet would be.

300 feet per inch, then ? inch is 1200 feet

? * 300 = 1200 * 1

The probability that a discrete random variable X takes on a particular value x is equal to the probability mass function (PMF) of X evaluated at x. The PMF of a discrete random variable X is defined as the derivative of its cumulative distribution function (CDF) with respect to x.

Given the CDF for X as F(x), the PMF for X is denoted as f(x) and can be computed as follows:

f(x) = F'(x) = dF(x)/dx

In this case, the CDF for X is given as:

F(0) = 0

F(1) = .15

F(2) = .45

F(3) = .55

F(4) = .85

F(5) = 1

To find the probability that x = 3, we need to compute the PMF of X at x = 3. Using the formula above, we have:

f(3) = F'(3) = dF(3)/dx

Since the CDF for X is a discrete function, we can compute the derivative by taking the difference between the values of the CDF at x = 3 and x = 2:

f(3) = F(3) - F(2) = .55 - .45 = .1

Therefore, the probability that x = 3 is .1.

Answer:

G = 109

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles.

12x-10 = 73+ 7x-3

Combine like terms.

12x-10 = 70+ 7x

Subtract 7x from each side.

12x-10-7x= 70+7x-7x

5x-10 = 70

Add 10 to each side.

5x-10+10 = 70+10

5x= 80

Divide each side by 5.

5x/5 = 80/5

x = 16

Answer:

x = 65.26 degrees or x = 245.26 degrees.

Step-by-step explanation:

To solve the equation 4tan(x)-7=0 for 0<=x<360, we can first isolate the tangent term by adding 7 to both sides:

4tan(x) = 7

Then, we can divide both sides by 4 to get:

tan(x) = 7/4

Now, we need to find the values of x that satisfy this equation. We can use the inverse tangent function (also known as arctan or tan^-1) to do this. Taking the inverse tangent of both sides, we get:

x = tan^-1(7/4)

Using a calculator or a table of trigonometric values, we can find the value of arctan(7/4) to be approximately 65.26 degrees (remember to use the appropriate units, either degrees or radians).

However, we need to be careful here, because the tangent function has a period of 180 degrees (or pi radians), which means that it repeats every 180 degrees. Therefore, there are actually two solutions to this equation in the given domain of 0<=x<360: one in the first quadrant (0 to 90 degrees) and one in the third quadrant (180 to 270 degrees).

To find the solution in the first quadrant, we can simply use the value we just calculated:

x = 65.26 degrees (rounded to two decimal places)

To find the solution in the third quadrant, we can add 180 degrees to the first quadrant solution:

x = 65.26 + 180 = 245.26 degrees (rounded to two decimal places)

So the solutions to the equation 4tan(x)-7=0 for 0<=x<360 are:

x = 65.26 degrees or x = 245.26 degrees.

Step-by-step explanation:

The R factor is used to access the strength of the relationship between a dependent and independent variable. The R factor ranges between - 1 and 1. With negative values depicting a negative linear relationship and positive values meaning a positive relationship. The closer the R factor is to - 1 or + 1, the greater the strength, a value of 0 means, no correlation exists.

Hence, a R factor of 0.15 depicts a positive but very weak relationship between cost and volume as the R value is close to 0.

The standard error is 0.0912.

The standard error (SE) is a measure of the precision of the sample mean estimate compared to the true population mean. To calculate the SE, we use the formula SE = standard deviation / square root of sample size.

In this scenario, the population parameter is 0.7, and the sample size is 30. If we assume that the sample mean is an unbiased estimator of the population mean, then the SE can be calculated using the above formula. However, we do not know the standard deviation of the population, so we use the sample standard deviation as an estimate.

Assuming the sample is large enough to assume normality, the formula becomes SE = \(\sqrt{(0.7*0.3)/30}\)   = 0.0912. Therefore, the standard error for a sample size of 30 is 0.0912. This means that if we were to take multiple samples of size 30 from the same population, the standard deviation of the means of those samples would be around 0.0912 away from the population parameter of 0.7 on average.

Step-by-step explanation:

Triangle ABC is a right angle triangle.

From the given right angle triangle,

AB represents the hypotenuse of the right angle triangle.

With m∠A as the reference angle,

AC represents the adjacent side of the right angle triangle.

BC represents the opposite side of the right angle triangle.

To determine tan m∠A, we would apply the tangent trigonometric ratio.

Tan θ = opposite side/adjacent side. Therefore,

Tan A = √32/2 = (√16 × √2)/2

Tan A = (4√2)/2

Tan A = 2√2
