part 3. Find the value of the trig function indicated, use Pythagorean theorem to find the third side if you need it.​

The additive inverse of a function f(x) is the function that, when added to f(x), equals 0. In other words, the additive inverse of f(x) is the function that "undoes" the effect of f(x).

The multiplicative inverse of a function f(x) is the function that, when multiplied by f(x), equals 1. In other words, the multiplicative inverse of f(x) is the function that "undoes" the effect of f(x) being multiplied by itself.

For the function h(x) = x - 24, the additive inverse is j(x) = -x + 24. This is because when j(x) is added to h(x), the result is 0:

\(h(x) + j(x) = x - 24 + (-x + 24) = 0\)

The multiplicative inverse of h(x) is k(x) = 1/(x - 24). This is because when k(x) is multiplied by h(x), the result is 1:

\(h(x) * k(x) = (x - 24) * 1/(x - 24) = 1\)

Therefore, the additive inverse of  \(h(x) = x - 24\) is \(j(x) = -x + 24\\\),

and the multiplicative inverse of \(h(x) = x - 24\)is \(k(x) = \frac{1}{x - 24}\).

In the given equation r = 2/5 t "r" is the dependent variable.

In mathematics, a variable is a symbol that represents a quantity that can take on different values. In many cases, variables can be divided into two types: dependent variables and independent variables.

An independent variable is a variable that can be changed freely, and its value is not dependent on any other variable in the equation.

A dependent variable is a variable whose value depends on the value of one or more other variables in the equation

Here we have

Lin notices that the number of cups of red paint is always  2/5 of the total number of cups.

She writes the equation r = 2/5 t to describe the relationship.

In the equation, r = 2/5 t, "t" represents the total number of cups, while "r" represents the number of cups of red paint.

Here "t" is the independent variable because it represents the total number of cups, which can be changed arbitrarily.

The value of "r" depends on the value of "t" because the number of cups of red paint is always 2/5 of the total number of cups.

The probability of picking one bolt and one nut is 1/2 or 50%.

To find the probability that one is a bolt and one is a nut, we need to use the formula for calculating the probability of two independent events happening together: P(A and B) = P(A) × P(B)

Let's first calculate the probability of picking a bolt from the box:

P(bolt) = number of bolts / total number of parts = 3/6 = 1/2

Now, let's calculate the probability of picking a nut from the box:

P(nut) = number of nuts / total number of parts = 3/6 = 1/2

Since the events are independent, the probability of picking a bolt and a nut in any order is:

P(bolt and nut) = P(bolt) × P(nut) + P(nut) × P(bolt)

P(bolt and nut) = (1/2) × (1/2) + (1/2) × (1/2)

P(bolt and nut) = 1/2

Therefore, the probability of picking one bolt and one nut is 1/2 or 50%.

the probability that one chosen part is a bolt and the other chosen part is a nut is 1, or 100%. This makes sense because if we choose two parts at random, we must get one bolt and one nut since there are three of each in the box.

To find the probability that one chosen part is a bolt and the other chosen part is a nut, we need to use the formula for probability:

Probability = (number of desired outcomes) / (total number of outcomes)

There are two ways we could choose one bolt and one nut: we could choose a bolt first and a nut second, or we could choose a nut first and a bolt second. Each of these choices corresponds to one desired outcome.

To find the number of ways to choose a bolt first and a nut second, we multiply the number of bolts (3) by the number of nuts (3), since there are 3 possible bolts and 3 possible nuts to choose from. This gives us 3 x 3 = 9 total outcomes.

Similarly, there are 3 x 3 = 9 total outcomes if we choose a nut first and a bolt second.

Therefore, the total number of desired outcomes is 9 + 9 = 18.

The total number of possible outcomes is the number of ways we could choose two parts from the box, which is the number of ways to choose 2 items from a set of 6 items. This is given by the formula:

Total outcomes = (6 choose 2) = (6! / (2! * 4!)) = 15

Putting it all together, we have:

Probability = (number of desired outcomes) / (total number of outcomes)
Probability = 18 / 15
Probability = 1.2

However, this answer doesn't make sense because probabilities should always be between 0 and 1. So we made a mistake somewhere. The mistake is that we double-counted some outcomes. For example, if we choose a bolt first and a nut second, this is the same as choosing a nut first and a bolt second, so we shouldn't count it twice.

To correct for this, we need to subtract the number of outcomes we double-counted. There are 3 outcomes that we double-counted: choosing two bolts, choosing two nuts, and choosing the same part twice (e.g. choosing the same bolt twice). So we need to subtract 3 from the total number of desired outcomes:

Number of desired outcomes = 18 - 3 = 15

Now we can calculate the correct probability:

Probability = (number of desired outcomes) / (total number of outcomes)
Probability = 15 / 15
Probability = 1

So the probability that one chosen part is a bolt and the other chosen part is a nut is 1, or 100%. This makes sense because if we choose two parts at random, we must get one bolt and one nut since there are three of each in the box.

For each given sample result, the p-value and conclusion are as follows:

a. p-value = 0.0067, Conclusion: Reject H0,  b. p-value = 0.0830, Conclusion: Fail to reject H0, c. p-value = 0.0322, Conclusion: Reject H0

d. p-value = 0.6221, Conclusion: Fail to reject H0

The p-value is a measure of the evidence against the null hypothesis (H0). It represents the probability of obtaining a sample result as extreme as or more extreme than the observed result, assuming the null hypothesis is true. A p-value less than the significance level (α) indicates strong evidence against the null hypothesis and suggests that the alternative hypothesis (Ha) may be true.

a. For p = .68, we need to determine the probability of observing a sample proportion as extreme as or less than .68, assuming the null hypothesis is true. By conducting the appropriate statistical test (e.g., using the normal approximation to the binomial distribution), we find the p-value to be 0.0067. Since the p-value is less than α = .05, we reject the null hypothesis and conclude that there is evidence to support the claim that the proportion is less than .75.

b. For p = .72, the p-value represents the probability of observing a sample proportion as extreme as or less than .72. Calculating the p-value using the appropriate statistical test yields 0.0830. Since the p-value is greater than α = .05, we fail to reject the null hypothesis. Therefore, we do not have sufficient evidence to conclude that the proportion is less than .75.

c. With p = .70, the p-value indicates the probability of observing a sample proportion as extreme as or less than .70. The calculated p-value is 0.0322. As the p-value is less than α = .05, we reject the null hypothesis and conclude that there is evidence to suggest that the proportion is less than .75.

d. For p = .77, the p-value represents the probability of observing a sample proportion as extreme as or greater than .77. After performing the necessary calculations, we find the p-value to be 0.6221. Since the p-value is much greater than α = .05, we fail to reject the null hypothesis. Consequently, we do not have sufficient evidence to conclude that the proportion is less than .75.

The amplitude of v(t) at steady-state is (a) Amplitude = KFc. This is because the amplitude of the response in a linear system is proportional to the amplitude of the forcing function, and the constant of proportionality is the system gain, K.

In this case, the forcing function has an amplitude of Fc, and the system gain is K, so the amplitude of the response at steady-state is K times Fc, or KFc. The amplitude of v(t) at steady-state can be found by considering the relationship between the system gain (K) and the forcing function f(t). Given the forcing function f(t) = Fc * sin(100t/τ), we can determine the steady-state response by taking the amplitude of the sinusoidal forcing function and multiplying it by the system gain K. Hence, the amplitude of v(t) at steady-state is: Amplitude = K * Fc Therefore, the best answer is: a. Amplitude = KFc.

The value of t after solving the equation -91.2e^(-0.5t)-19.6t+91.2=0 is 4.82.

Given:

-91.2e^(-0.5t) - 19.6t + 91.2 = 0

We need to find the value of 't' which satisfies the given equation.

In order to solve this equation, we can use Newton-Raphson method.

Newton-Raphson Method: Newton-Raphson method is used to find the root of the given equation.

The formula for Newton-Raphson method is given by x1 = x0 - f(x0) / f'(x0)

Where, x1 is the new value,

x0 is the old value,

f(x) is the function and

f'(x) is the derivative of the function.

f'(x) represents the slope of the curve at that particular point 'x'.

Let's find the derivative of the given function

f(t) = -91.2e^(-0.5t) - 19.6t + 91.2

f'(t) = -(-91.2/2)e^(-0.5t) - 19.6

Differentiate 91.2e^(-0.5t) using chain rule

=> 91.2 × (-0.5) × e^(-0.5t) = -45.6e^(-0.5t)

Now, we can rewrite the above equation as f(t) = -45.6e^(-0.5t) - 19.6t + 91.2

Using Newton-Raphson formula, we can find the value of t:

x1 = x0 - f(x0) / f'(x0)

Let's take x0 = 1x1 = 1 - f(1) / f'(1) = 1 - [-45.6e^(-0.5) - 19.6 + 91.2] / [-45.6 × (-0.5) × e^(-0.5) - 19.6]= 4.82

The value of t is 4.82.

The diameter of a wire significantly impacts its strength, range, and stiffness.

1. Strength: As the diameter of a wire increases, its overall strength improves. A larger cross-sectional area allows the wire to withstand greater forces before breaking. This is because the increased material can distribute force more effectively, resulting in enhanced tensile strength.

2. Range: The diameter of a wire also influences its range or length. Thicker wires tend to have shorter range capabilities compared to thinner wires. As the diameter increases, the weight and stiffness of the wire rise as well, making it harder to extend or coil over long distances. Conversely, thinner wires are more flexible and lightweight, enabling them to cover greater lengths.

3. Stiffness: Lastly, the diameter of a wire impacts its stiffness, which is the resistance of the wire to bending or deformation. With a larger diameter, the stiffness of the wire increases due to the higher amount of material present. This means that it requires more force to bend or change the shape of the wire, resulting in greater rigidity. On the other hand, wires with smaller diameters are more pliable and can easily be bent or manipulated.

In summary, the diameter of a wire plays a crucial role in determining its strength, range, and stiffness. Thicker wires exhibit enhanced strength and stiffness but may have limited range capabilities, while thinner wires are more flexible and suitable for longer distances but may not be as strong or rigid.

The system of equations for determining the dollar amount of  phone and computer sales are Sc = Sp + 600 and 0.05Sc + 0.04Sp = 1200

A commission is defined as the compensation paid to a person or entity based on the sale of a product. It is calculated on a percentage basis

Given:

Phone sales commission = 4%

Computer sales commission = 5%

Total commission = $129

Let Sc and Sp represent the dollar amount of phone sales and computer sales respectively

If Houa had $600 more in computer sales than in phone sales, the equation can be written as:

Sc = Sp + 600

Since Houa earns a 4% commission on phone sales and a 5% commission on computer sales, and a total commission of $129. Thus, the equation for the commission can be written as:

0.05Sc + 0.04Sp = 1200

Note:  5% = 5/100 = 0.05 and  4% = 4/100 = 0.04

The series ∑ (k = 1 to infinity) 5^k / k! is convergent.

The Ratio Test is a method used to determine the convergence or divergence of a series by comparing the ratio of consecutive terms to a limit. For the given series, let's apply the Ratio Test:

Taking the ratio of consecutive terms:

|5^(k+1) / (k+1)!| / |5^k / k!|

Simplifying the expression:

|(5^(k+1) / (k+1)!) * (k! / 5^k)|

|5 / (k + 1)|

Now, we take the limit of this ratio as k approaches infinity:

lim(k->infinity) |5 / (k + 1)| = 0

Since the limit is less than 1, we can conclude that the series converges by the Ratio Test. In other words, the series ∑ (k = 1 to infinity) 5^k / k! is convergent.

The Ratio Test works by comparing the growth rate of consecutive terms in a series. If the ratio of consecutive terms approaches a value less than 1 as k goes to infinity, then the series converges. In this case, as the term k increases, the ratio 5 / (k + 1) approaches 0, indicating that the series converges.

The dimensions of the cylinder with the greatest volume that can be inscribed in the sphere are a height of 12 feet and a radius of 6 feet, and its maximum volume is approximately 1,152π cubic feet.

To find the dimensions of the cylinder with the greatest volume that can be inscribed in the given sphere, we need to consider the diameter of the sphere, which is twice the radius (12 feet). This diameter will be the height of the cylinder.

The maximum volume of the cylinder can be found by using the formula for the volume of a cylinder: V = πr^2h, where r is the radius of the cylinder and h is its height. Since the cylinder is inscribed in the sphere, its radius will be half of the diameter of the sphere, which is 6 feet. Therefore, we have:

The sinusoidal function that satisfies the given attributes is f(x) = 10 * sin(2π/5 * x - π/5) + 31.

To find a sinusoidal function with the given attributes, we can use the general form of a sinusoidal function:

f(x) = A * sin(Bx + C) + D

where A represents the amplitude, B represents the frequency (related to the period), C represents the phase shift, and D represents the vertical shift.

Amplitude: The given amplitude is 10. So, A = 10.

Period: The given period is 5. The formula for period is P = 2π/B, where P is the period and B is the coefficient of x in the argument of sin. By rearranging the equation, we have B = 2π/P = 2π/5.

Midline: The given midline is y = 31, which represents the vertical shift. So, D = 31.

f(3) = 41: We are given that the function evaluated at x = 3 is 41. Substituting these values into the general form, we have:

41 = 10 * sin(2π/5 * 3 + C) + 31

10 * sin(2π/5 * 3 + C) = 41 - 31

10 * sin(2π/5 * 3 + C) = 10

sin(2π/5 * 3 + C) = 1

To solve for C, we need to find the angle whose sine value is 1. This angle is π/2. So, 2π/5 * 3 + C = π/2.

2π/5 * 3 = π/2 - C

6π/5 = π/2 - C

C = π/2 - 6π/5

Now we have all the values to construct the sinusoidal function:

f(x) = 10 * sin(2π/5 * x + (π/2 - 6π/5)) + 31

Simplifying further:

f(x) = 10 * sin(2π/5 * x - 2π/10) + 31

f(x) = 10 * sin(2π/5 * x - π/5) + 31

Therefore, the sinusoidal function that satisfies the given attributes is f(x) = 10 * sin(2π/5 * x - π/5) + 31.
