Is y=10/x a linear function, explain

Answer:

Sa / Va = time traveled by bus a

Sb  / Vb + 3/4  = time traveled by van b

Sa / Va = Sb  / Vb + 3/4      times traveled are the same

            = (220 - Sa) / Vb + 3/4

Sa ( 1 / Va + 1 / Vb) = 220 / 80 + 3/4

Sa (140 / 4800) = 3.5

Sa = 120 km

Check: 120 km / 60 km/hr = 2 hr = Ta

Sb = 1.25 * 80 = 100 km   traveling for 1.25 hrs

Given:

For simplicity, suppose f is infinitely differentiable at x.

We can use h^2f(x+h)-2f(x)+f(x-h) to approximate f''(x).

To show that, h^2f(x+h)-2f(x)+f(x-h)−f′′(x)=O(h^2).

Solution:

           As per Taylor’s Theorem,

                            f(x+h)=f(x)+hf′(x)+h^2/2!f′′(x)+⋯f(x−h)=f(x)−hf′(x)+h^2/2!f′′(x)−⋯

Therefore,           2f(x+h)−2f(x)=2hf′(x)+h^2f′′(x)+⋯

Substituting the above values in given equation,we get

                            h^2f(x+h)-2f(x)+f(x-h) = h^2f′′(x)+O(h^3)\

Therefore,

               h^2f(x+h)-2f(x)+f(x-h) −f′′(x) = O(h^2)

Thus, the result is proved.

Answer:

Alternate exterior angles

Step-by-step explanation:

Answer: To create a 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night, we can use the following formula:

CI = p ± z*(sqrt((p*(1-p))/n))

where:

p = proportion of college students who get 8 or more hours of sleep per night (356/2282 = 0.1559)

n = sample size (2282)

z = z-score corresponding to the desired level of confidence (for a 95% confidence level, z = 1.96)

Substituting the given values, we get:

CI = 0.1559 ± 1.96*(sqrt((0.1559*(1-0.1559))/2282))

CI ≈ (0.1301, 0.1818)

Rounding to four decimal places, the 95% confidence interval for the proportion of college students who get 8 or more hours of sleep per night is (0.1301, 0.1818).

Answer:

Step-by-step explanation:

The future value of the monthly deposit which earns 0.475 monthly interest will be $10,944.67 after 16 months.

The future value can be determined using the future value annuity formula or an online finance calculator.

The future value represents the periodic deposits compounded periodically at an interest rate.

N (# of periods) = 16 months

I/Y (Interest per year) = 5.7% (0.475% x 12)

PV (Present Value) = $0

PMT (Periodic Payment) = $660

Results:

Future Value (FV) = $10,944.67

The sum of all periodic payments = $10,560.00

Total Interest = $384.67

Thus, using an online finance calculator, the future value of the monthly deposits is $10,944.67.

An estimate for the total volume of food and water you've ingested in the last day is 3000-5000 milliliters. On average, the heart pumps about 5 liters of blood per minute. 10-20% or more error I'm expecting. Calculating heart blood volume compared to food and drink consumption is crucial for understanding circulation and liver function.

D.1 Estimating the amount of food and water consumed in a day can be difficult without specific measurements, but a rough estimate can be made based on typical intake amounts. On average, a person may consume 2-3 liters of water and 1000-2000 calories per day, resulting in an estimated total volume of 3000-5000 milliliters.

D.2 The amount of blood pumped by the heart varies from person to person and depends on factors such as heart rate and overall health. On average, the heart pumps about 5 liters of blood per minute, which is much larger than the estimated volume of food and water intake.

D.3 Estimating food and water intake and blood flow is prone to error due to variability and uncertainties in personal measurements. Individuals' habits, health, and physical activity levels can affect these estimates, potentially resulting in a significant error of 10-20% or more.

D.4 The calculation of the heart's blood volume compared to food and drink consumption is crucial for understanding the circulation system and liver role.

The liver processes nutrients, detoxifies, and produces blood components, while the heart is responsible for circulating blood throughout the body. The vast difference in volume between the two is emphasized, emphasizing the heart's crucial role in maintaining circulation.

The degrees of freedom for a one-sample t-test with an alpha level of .05 and a sample size of 88 students is 87.

The degrees of freedom are calculated by subtracting 1 from the sample size, which in this case is 88 - 1 = 87. The degrees of freedom represent the number of independent pieces of information available for estimating the population parameter.

In this context, it reflects the number of students in the sample whose scores can vary freely while still being able to estimate the population mean. The t-distribution is used in the t-test to determine the critical value for hypothesis testing and to calculate the p-value.

In a one-sample t-test, the researcher is comparing the mean of a single sample to a known or hypothesized population mean. The degrees of freedom are a crucial parameter in determining the critical value from the t-distribution. The formula to calculate the degrees of freedom is simply the sample size minus 1. In this case, the sample size is 88, so the degrees of freedom would be 87.

Having 87 degrees of freedom means that the sample data has 87 independent pieces of information that contribute to estimating the population mean. With this information, the researcher can use the t-distribution table or statistical software to find the critical t-value for a one-sided test with an alpha level of .05.

suricce area

The hare can afford to nap for a maximum time of 3,690 seconds without losing the race if his speed is 15 m/s.

After running for 7 seconds, the hare has covered a distance of:

\(distance = speed \times time\\distance = 15 \times 7\\\)

distance = 105m

The hare is now 895 m away from the starting line and 100 m away from the finish line.

The hare needs to cover a distance of 100 m to reach the finish line, while the tortoise needs to cover a distance of 895 m.

calculate the time it would take the tortoise to reach the finish line:

\(time = \frac{100}{0.27}\) = 3704 seconds

The maximum speed of the hare is 15 m/s, which means the time it would take the hare to cover the distance is:

\(time = \frac{100}{15}\) = 6.67 seconds

so, the time hare have to nap so that he does not lose race = 3704 - (7+6.67) ≅3690 seconds

The value of the trigonometric function is -

sin(θ) = 21 / 29,

cos(θ) = 20/29,

csc(θ) = 29/21,

sec(θ) = 29/20,

cot(θ) = 20/21.

In a nutshell, trigonometric functions, also referred to as circular functions, are the functions of a triangle's angle. This suggests that these trig functions provide the relationship between a triangle's angles and sides. Sine, cosine, tangent, cotangent, secant, and cosecant are the fundamental trigonometric functions.

Given that,

tan (θ) = - 21 / 20

We can infer from the value that the triangle's two legs are 21 and 20, respectively.

Using the Pythagorean theorem, we can:

\(a^{2} + b^{2} = c^{2}\)

\((21)^{2} + (20)^{2} = c^{2}\)

441 + 400 =\(c^{2}\)

c = 29

The value of :

sin(θ) = 21 / 29

cos(θ) = 20/29

csc(θ) = 29/21

sec(θ) = 29/20

cot(θ) = 20/21

Hence, the value of the trigonometric function is

sin(θ) = 21 / 29,

csc(θ) = 29/21,

sec(θ) = 29/20,

Solving for variables is a quick and easy concept to learn. Solving for variables is simple. All you need to do is figure out what number can replace the variable.

Vocabulary

variable - a symbol that represents a mathematical object.

The equation: -6h + 12 = -36

Lets solve this step by step!

When a variable is right next to a number, for example, -6h, this means the same as 6 · h and 6 × h. This means we will be multiplying. The equation can be represented as -6(h) + 12 = -36. Because we know that negative + negative = positive, we know h cannot be a negative number as the answer is -36. What we can do to solve this is substitute numbers as h to see what can equal -36. -6(8) + 12 = -36, so, this means that h = 8.

Step-by-step explanation:

A 3-digit number cannot start with 0, so the leftmost digit is a choice of 6 digits out of the 7. The middle digit can be chosen from all 7 digits minus the one already used, so there are 6 choices. The right digit can be chosen from 5.

6 × 6 × 5 = .180

The number of three-digit numbers that can be formed from the digits 0, 1, 2, 3, 4, 5, and 6 is 180.

This can be calculated by finding the number of element availabe at first place which is 6 excluding 0 than for second position 6 as first number is excluded and 0 is added and for the last positon the number of possibe combination is 5 as 2 digits are already used.
