The coordinates of the point on y sin(x) that is closest to the point (4, y) is (3.579, 0.323).

To find the point on the curve y = sin(x) that is closest to the point (4, y), we can use the distance formula between two points. The distance between two points (x1, y1) and (x2, y2) is given by:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

We want to minimize this distance, so we can minimize the square of the distance:

d^2 = (x2 - x1)^2 + (y2 - y1)^2

Let (x, sin(x)) be a point on the curve y = sin(x). Then the distance squared between this point and (4, y) is:

d^2 = (x - 4)^2 + (sin(x) - y)^2

To minimize this distance, we can take the derivative of d^2 with respect to x, set it equal to zero, and solve for x:

d^2 = (x - 4)^2 + (sin(x) - y)^2

d^2/dx = 2(x - 4) + 2(sin(x) - y)cos(x) = 0

Simplifying this expression, we get:

x - 4 + (sin(x) - y)cos(x) = 0

We can solve this equation numerically using a numerical method such as Newton's method or the bisection method. Once we have found the value of x that minimizes the distance, we can find the corresponding value of y = sin(x) and the closest point on the curve is (x, sin(x)).

Using a numerical method, we can find that the value of x that minimizes the distance is approximately 3.579. Therefore, the closest point on the curve is (3.579, sin(3.579)) which is approximately (3.579, 0.323).

The United States forces arrived in Europe in 1917 and helped tip the scales in favor of Britain and France, leading to an Allied victory over Germany and Austria in November 1918. More than four million Americans had served in the armed forces by the time of the armistice, and 116,708 had died.

When World War I broke out in Europe in 1914, President Woodrow Wilson declared that the United States would remain neutral, and many Americans agreed. However, public opinion on neutrality began to shift after the sinking of the British ocean liner Lusitania by a German U-boat in 1915, which killed nearly 2,000 people, including 128 Americans.

Wilson requested a declaration of war against Germany in response to the Zimmermann telegram, which threatened an alliance between Germany and Mexico against America.

The United States of America officially entered World War I on April 6, 1917. Millions of Americans served overseas and helped the war effort at home over the next year and a half. Their contributions aided in the victory of the war and shaped both America and the world for future generations.

a) Probability that the flight will accommodate all ticketed passengers who show up is 0.16

b) Probability that not all ticketed passengers who show up can be accommodated is 0.67

c) The probability that you will be able to take the flight is 96%

Probability is a powerful tool to understand the likelihood of different outcomes in various situations, including overbooking of flights

In this scenario, the random variable y represents the number of ticketed passengers who actually show up for the flight, out of a total of 55 ticketed passengers for a plane with only 50 seats. The probability mass function of y provides the probabilities for each possible outcome.

(a) The probability that the flight will accommodate all ticketed passengers who show up is the probability of y being equal to 50, which is 0.16.

(b) The probability that not all ticketed passengers who show up can be accommodated is the sum of the probabilities of y being greater than 50, which is

=> 0.05 + 0.10 + 0.13 + 0.14 + 0.25 = 0.67.

(c) If you are the first person on the standby list, the probability of being able to take the flight is the probability of y being less than or equal to 50, which is 0.89. This means that there is an 89% chance that you will get on the plane. If you are the third person on the standby list, the probability is the probability of y being less than or equal to 52 (since two people need to cancel or not show up for you to get on), which is 0.96. This means that there is a 96% chance that you will get on the plane.

Answer:

a. (-0.93,-0.37)

Step-by-step explanation:

The unit circle is a circle with a radius of 1 that is centered at the origin (0, 0) of a coordinate plane. To find the coordinates of a point on the unit circle corresponding to a given central angle, we can use the relationship between the angle and the coordinates of the point.

For a central angle of 202 degrees, the point on the unit circle would be found by using the formula:

x = cos(202°)

y = sin(202°)

Rounding the results to the nearest hundredth, we have:

x = -0.927

y = -0.3746

So the coordinates of the point on the unit circle corresponding to the central angle of 202 degrees are (-0.93, -0.37).

Answer:

a. (-0.93, -0.37)

Step-by-step explanation:

A unit circle has its center at (0, 0) and a radius of 1.

The coordinates on the unit circle (x, y) are equivalent to (cos θ, sin θ), where θ is the angle (measured anticlockwise from the positive x-axis).

Therefore, given θ = 202°, the coordinates of the corresponding point on the unit circle are:

Therefore, the point on the unit circle is (-0.93, -0.37).

The vector equation of the tangent line is <9t+9, t+2, t^2>.

To find the tangent line to the curve at t=1, we need to find the derivative of r(t) and evaluate it at t=1.

r(t) = 9t <1> + 1 <2> + t^2 <3>

Taking the derivative of r(t) with respect to t, we get:

r'(t) = 9 <1> + 1 <0> + 2t <3>

Evaluating r'(1), we get:

r'(1) = 9 <1> + 1 <0> + 2(1) <3> = 9 <1> + 2 <3>

So the vector equation of the tangent line at t=1 is:

r(1) + tr'(1) = <9,1,1> + t<9,2,0>

Simplifying, we get:

<9t+9, t+2, t^2>

So the vector equation of the tangent line is <9t+9, t+2, t^2>.

Step-by-step explanation:

Surveys suggest that about 7 percent of people in the united states experience a depression during a given year.

The United States experienced a depression during the 1930s, which lasted from 1929 to 1939. This was one of the longest and deepest economic downturns in U.S. history. The Great Depression caused widespread unemployment, poverty, and hardship throughout the country.

The stock market crash of 1929 and the subsequent bank failures caused a sharp decline in industrial and agricultural production, as well as a dramatic drop in consumer spending. As a result, millions of Americans were left without jobs, and many lost their homes and other possessions.

The government responded to the crisis with a series of programs and initiatives, such as the New Deal, to stimulate the economy and provide relief for those most affected. These programs helped to create jobs and provide economic stability, but the Great Depression would not end until the U.S. entered World War II in 1941.

Answer: We can start by expanding the square on the left-hand side of the equation:

(s + t)^2 = s^2 + 2st + t^2

We know that s^2 + t^2 = 6, so we can substitute that into the equation:

(s + t)^2 = 6 + 2st

We also know that st = c + 5, so we can substitute that into the equation:

(s + t)^2 = 6 + 2(c + 5)

Simplifying the right-hand side:

(s + t)^2 = 6 + 2c + 10

So, in terms of c, (s + t)^2 = 6 + 2c + 10.

a) Increased by 44 students per year= N(t) = 240 + 44t

b) Decreased by 32 students per year=N(t) = 240 - 32t

c) Increased by 40 students every 2 years=N(t) = 240 - 32t

d) Decreased by 24 students every 4 years=N(t) = 240 - 32t

e) Remained constant= N(t) = 240

f) Increased by 5 students every semester (twice in a year)=N(t) =240+10t

The original population of students in the year 2000 is 240.

[tex]N_0=240[/tex]

Let the number of years = t

a) If the population increased by 44 students every year, the population, after t years, would have increased by 44t

Therefore,

[tex]N(t)=N_0+44t[/tex]

N(t) = 240 + 44t

b) If the population decreased by 32 students per year, the population, after t years, would have decreased by 32t

Therefore,  [tex]N(t)=N_0-32t[/tex]

N(t) = 240 - 32t

c) If the population Increased by 40 students every 2 years and increase is uniform per year, the population will increase by 40/2 = 20 students in 1 year. So in t years, the population would increase by 20 t.

Therefore,

Note that "ε" and "δ" are the Greek letters epsilon and delta, respectively, and they are used to represent small positive numbers. This definition says that if we want the limit of f(x) to be L, we can find a positive number δ such that the distance between f(x) and L is less than ε whenever x is within δ units of a (but not equal to a).
