Answer: 139 feet

Step-by-step explanation:I used tan. Tan(44) = x/140

x = 140(Tan 44)

x = 135.196

The transit is 4, so we add that to 135.

This makes 139 feet.

The given system of equation is,

Rewrite equation (2).

Now, put y=10-x in equation (1).

Rewrite the above equation and solve for x.

Hence,

x=-8 is not in the first quadrant.

Put x=2 in equation (2) to find the corresponding value of y.

The coordinate (x, y)=(2, 8) is in the first quadrant.

So, the x coordinate of the solution located in the first quadrant is x=2 .

To test a hypothesis using the p-value approach, you need to follow these steps:

1. Formulate the null and alternative hypotheses:
  - The null hypothesis, denoted as H0, states that there is no significant difference or relationship between the variables being studied.
  - The alternative hypothesis, denoted as Ha or H1, states that there is a significant difference or relationship between the variables.

2. Verify the requirements of the test:
  - Before performing the hypothesis test, you need to ensure that the assumptions and requirements of the test are met. These requirements may vary depending on the type of test and data you have. Common requirements include independence, random sampling, normality, and equal variances.

3. Choose an appropriate significance level (α):
  - The significance level, denoted as α, is the predetermined threshold below which we reject the null hypothesis. Commonly used significance levels are 0.05 (5%) and 0.01 (1%).

4. Calculate the test statistic:
  - The test statistic is a numerical value that summarizes the evidence against the null hypothesis. The specific test statistic depends on the type of hypothesis test being conducted. For example, if you're testing the difference between two population means, you might use the t-test or z-test.

5. Calculate the p-value:
  - The p-value is the probability of obtaining a test statistic as extreme as the one observed, assuming that the null hypothesis is true. It measures the strength of the evidence against the null hypothesis. A small p-value suggests strong evidence against the null hypothesis, while a large p-value suggests weak evidence.

6. Make a decision:
  - Compare the p-value to the significance level (α) you chose in step 3. If the p-value is less than or equal to α, reject the null hypothesis. If the p-value is greater than α, fail to reject the null hypothesis.

Remember that failing to reject the null hypothesis doesn't necessarily prove it to be true. It simply means that there is not enough evidence to support the alternative hypothesis.

The length of the minor arc AB is approximately 16.8 cm (to 1 decimal place).

To find the length of the minor arc AB, we need to calculate the circumference of the entire circle and then find the fraction of the circumference represented by the central angle OAB.

The formula for the circumference of a circle is given by C = πd, where C is the circumference and d is the diameter.

Given that the diameter of the circle is 68 cm, we can calculate the circumference:

C = πd

C = π(68 cm)

C ≈ 213.628 cm

Now, to find the length of the minor arc AB, we need to find the fraction of the circumference represented by the central angle OAB. Since the central angle is given in degrees, we can use the formula:

Length of minor arc AB = (Central angle/360°) * Circumference

Length of minor arc AB = (28°/360°) * 213.628 cm

Length of minor arc AB ≈ 16.776 cm

c = 50 liters (initial amount of soup)

d = 10 liters (amount of water added)

1: Calculate the initial amount of broth in the soup.

The soup is 50% broth, so 50% of 50 liters is (50/100) * 50 = 25 liters of broth.

2: Calculate the final amount of soup after adding water.

The initial amount of soup is 50 liters, and 10 liters of water are added, so the final amount of soup is 50 + 10 = 60 liters.

3: Calculate the final amount of broth in the soup.

The initial amount of broth is 25 liters, and no broth is added or removed during the process, so the final amount of broth remains the same at 25 liters.

4: Calculate the final percentage of broth in the soup.

To find the percentage of broth in the soup, divide the final amount of broth by the final amount of soup and multiply by 100.

Step-by-step explanation:

The interval of continuity of the function is continuous given y = 2 (x + 4 ) 2 + 8 is (-∞, ∞).

A function is continuous at a point if the function value exists and is finite at that point, and the limit of the function as the input approaches that point from the left and right side is equal to the function value at that point. In other words, the function has no sudden jumps or discontinuities at that point.

In the case of the function y = 2(x + 4)² + 8, the function is defined and continuous for all real numbers x. There are no values of x for which the function is undefined or has a discontinuity, so the function is continuous for all values of x, meaning that the interval of continuity is (-∞, ∞).

Answer:

Hello,

Step-by-step explanation:

Just find the longest measure.

A boat takes 3.40 hours to travel 25.0 km down a river, then 4.60 hours to return, so the river is flowing at the speed of 0.95km/hrs.

Let x represent the boat's speed on still water.

Let y equal the current's speed.

The time is 3.40 hours, and the rate is x + y with the current.

The time is 4.60 hours, and the rate against the current is x - y.

rate x time = downstream

distance (x + y) * 3.40 = 25

Thus, upstream, 3.4x + 3.4y = 25. (x - y) * 4.60 = 25 so 4.6x - 4.6y = 25

Add 4.6 to both sides of the "downstream" equation and 3.4 to both sides of the "upstream" equation:

15.64x + 15.64y = 115

15.64x - 15.64y = 85

When the two equations are combined: 31.28x = 200, so x = 6.4

In other words, 15.64(6.4) + 15.64(y) = 115 and 100 + 15.64y = 115 are equivalent to 15.64x + 15.64y = 115.

120 is subtracted from both sides: 15.64y = 15, so y = 0.95

The speed of the boat in still water is 6.4 km per hour

The speed of the current is 0.95 km per hour.

The speed of the plane in still air is 425 mph.

Let's denote the speed of the plane in still air as v, and the speed of the wind as w.

For the first leg of the trip, against the headwind, the effective ground speed is v - w. For the second leg of the trip, with the wind, the effective ground speed is v + w.

Using the formula distance = speed × time, we have:

Time against headwind = 3300 / (v - w)

Time with the wind = 3300 / (v + w)

Given that the return trip with the wind took 16 hours less time, we can set up the equation:

3300 / (v + w) - 16 = 3300 / (v - w)

Simplifying the equation by multiplying both sides by (v - w)(v + w), we get:

3300(v - w) - 16(v - w)(v + w) = 3300(v + w)

3300v - 3300w - 16v² + 16w² = 3300v + 3300w

16w² - 16v² = 6600w

w² - v² = 412.5

Substituting w = 8 mph, we have:

64 - v² = 412.5

v² = 348.5

v ≈ 18.67

Therefore, the speed of the plane in still air is approximately 18.67 x 23,040 = 429.49 mph (rounded to two decimal places).

i. To find the Fourier transform of (t - 2) - 38(t - 3), we can use the linearity property of the Fourier transform. The Fourier transform of (t - 2) can be found using the time-shifting property, and the Fourier transform of -38(t - 3) can be found by scaling and using the frequency-shifting property. Adding the two transforms together gives [(jw)^2 + 38jw]e^(-2jw).

ii. The function e^(-2t)u(t) is the product of the exponential function e^(-2t) and the unit step function u(t). The Fourier transform of e^(-2t) can be found using the time-shifting property as 1/(jw + 2). The Fourier transform of u(t) is 1/(jw), resulting in the Fourier transform of e^(-2t)u(t) as 1/(jw + 2).

iii. The function e^(-3t+12)u(t-4) can be rewritten as e^(-2t)u(t-4)e^(12jw) using the time-shifting property. From the result of ii., we know the Fourier transform of e^(-2t)u(t-4) is 1/(jw + 2). Multiplying this by e^(12jw) gives the Fourier transform of e^(-3t+12)u(t-4) as e^(-2t)u(t-4)e^(12jw).

iv. To find the Fourier transform of e^(-2|t|)cos(t), we can use the definition of the Fourier transform and apply the properties of the Fourier transform. By splitting the function into even and odd parts, we find that the Fourier transform is [(2jw)/(w^2+4)].

Answer:

128 cm

Step-by-step explanation:

After the first bounce

height = \(\frac{4}{5}\) × 250 = 4 × 50 = 200 cm

After the second bounce

height = \(\frac{4}{5}\) × 200 = 4 × 40 = 160 cm

After the third bounce

height = \(\frac{4}{5}\) × 160 = 4 × 32 = 128 cm

The ball will rise to 128 cm after the third bounce, if dropped from a height of 250 cm.

Multiplication is the process of operating a number by adding the number repeatedly to itself up to the times of the other number which is multiplied to the given number.

Mathematically, we can define this as for two numbers p and q, p × q implies that p is added to itself q times or q is added to itself p times.

Initial height = 250 cm

On each bounce, a ball rises to 4/5 of its previous height.

On first bounce,

Height = (4/5) × 250 = 4 × 50 = 200 cm

On second bounce,

Height = (4/5) × 200 = 4 × 40 = 160 cm

On third bounce,

Height =  (4/5) × 160 = 4 × 32 = 128 cm

This problem can also be solved using geometric progression with the formula for nth term as (a rⁿ⁻¹) where a is the first term 250, r is the common ratio 4/5 and n is 4, implies the 4th term.

Hence the height ball rise after the third bounce is 128 cm.

The probability a customer spends more than $7 each visit is approximately 0.9082. The survey question is biased as it is leading and implies a comparison with a specific competitor.

The type of sampling method used is not specified in the given information.

Using the standard normal distribution, the probability that a customer spends less than $14 can be found as

P(X < 14) = P(Z < (14-11)/3) = P(Z < 1) = 0.8413

Therefore, the probability that a customer spends less than $14 each visit is 0.8413.
