Create a trigonometric function that models the ocean tide..
Explain why you chose your function type. Show work for any values not already outlined above.

Answers

Answer 1

Answer:

One possible function that models the ocean tide is:

h(t) = A sin(ωt + φ) + B

where:

h(t) represents the height of the tide (in meters) at time t (in hours)

A is the amplitude of the tide (in meters)

ω is the angular frequency of the tide (in radians per hour)

φ is the phase shift of the tide (in radians)

B is the mean sea level (in meters)

This function is a sinusoidal function, which is a common type of function used to model periodic phenomena. The sine function has a natural connection to circles and periodic motion, making it a good choice for modeling the regular rise and fall of ocean tides.

The amplitude A represents the maximum height of the tide above the mean sea level, while B represents the mean sea level. The angular frequency ω determines the rate at which the tide oscillates, with one full cycle (i.e., a high tide and a low tide) occurring every 12 hours. The phase shift φ determines the starting point of the tide cycle, with a value of zero indicating that the tide is at its highest point at time t=0.

To determine specific values for A, ω, φ, and B, we would need to gather data on the tide height at various times and locations. However, typical values for these parameters might be:

1. A = 2 meters (representing a relatively large tidal range)

2. ω = π/6 radians per hour (corresponding to a 12-hour period)

3. φ = 0 radians (assuming that high tide occurs at t=0)

4. B = 0 meters (assuming a mean sea level of zero)

Using these values, we can write the equation for the tide as:

h(t) = 2 sin(π/6 t)

We can evaluate this equation for various values of t to get the height of the tide at different times. For example, at t=0 (the start of the cycle), we have:

h(0) = 2 sin(0) = 0

indicating that the tide is at its lowest point. At t=6 (halfway through the cycle), we have:

h(6) = 2 sin(π/2) = 2

indicating that the tide is at its highest point. We can also graph the function to visualize the rise and fall of the tide over time:

Tide Graph

Overall, this function provides a simple and effective way to model the ocean tide using trigonometric functions.

You randomly select 500 students and observe that 85 of them smoke. Estimate the probability that a randomly selected student smokes.
a. 0.27
b. 0.50, since there are two possible outcomes for every student surveyed. smoke, don't smoke
c. 0.17
d. 1.2

Answers

Option C is the correct answer. 0.17 is the probability that a randomly selected student smokes out of 500 students, given 85 smoke.

By dividing the total number of students observed (500) by the number of students who smoke (85) in this scenario, it is possible to estimate the probability of smoking among the 500 students.

This results in a ratio of 0.17, or 17%. The estimated likelihood that a randomly chosen student smokes is therefore 0.17, meaning that roughly 17 out of every 100 students in the population smoke. It is crucial to remember that this is only an estimate, and the true probability could change slightly depending on the size and sampling method.

The estimated probability does, however, have a tendency to converge to the true probability when the sample size is sufficient.

Hence, the probability that a randomly selected student smokes  is 0.17

Answers

As a result, the probability that the average battery life exceeds 553.9 minutes is 0.0262 (or 2.62%). The answer, rounded to four decimal places, is 0.0262.

What is probability?

Probability serves as an indicator of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing an unlikely event and 1 representing an unavoidable event. Switching a fair coin and coin flips has a probability of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probability theory is a branch of mathematics that studies happenings rather than their properties. It is applied in many fields, including statistics, fund, science, and engineering.

The central limit theorem can be used to approximate the sample mean distribution as a normal distribution with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size.

The standard error of the mean (SE) is calculated as follows:

SE = σ/√n

Where n is the sample size and is the population standard deviation.

SE = 83/√160 = 6.575

Z = (X - μ) / SE

Where X represents the sample mean, is the population mean, and SE represents the standard error of the mean.

Z = (553.9 - 541) / 6.575 = 1.94

As a result, the probability that the average battery life exceeds 553.9 minutes is 0.0262 (or 2.62%). The answer, rounded to four decimal places, is 0.0262.

Therefore, the scale factor of the dilation of the shape is 2.

What is scale factor?

A scale factor is a ratio that describes the proportional relationship between two similar figures. It represents how much larger or smaller one figure is compared to the other, and it is calculated by dividing a corresponding measurement (such as side length, perimeter, or area) of the larger figure by the corresponding measurement of the smaller figure. Scale factor is used in mathematics, particularly in geometry and measurement, to describe the transformation of one figure into another through dilation or resizing. It is represented by a number or a ratio, such as 2:1 or 1/2, which indicates how many times larger or smaller the new figure is compared to the original.

Here,

In the given picture, it appears that the distance from the center of dilation (the origin) to the pre-image (the original figure) is 4 units, and the distance from the center of dilation to the image (the transformed figure) is 8 units. The scale factor of the dilation is equal to the ratio of the distance from the center of dilation to the image and the distance from the center of dilation to the pre-image.

So, the scale factor of the dilation is:

8 units ÷ 4 units = 2

What is the slope of a line that passes through the points (-2, 3) and (4, -12)?

Answers

The slope of a line passing through two points (x1,y1) and (x2,y2) is given by:

slope = (y2 - y1)/(x2 - x1)

Using the coordinates of the two given points, we have:

slope = (-12 - 3)/(4 - (-2))
slope = (-15)/(6)
slope = -5/2

Therefore, the slope of the line that passes through (-2, 3) and (4, -12) is -5/2.

Answers

a) The first four nonzero terms of the power series for f(x) about x=0 are

e^6 - 2x^2 + (2x^4)/2! - (2x^6)/3!

The general term of the power series is (-2)^n (2x)^(2n) / (2n)!

b) The interval of convergence of the power series is (-∞, ∞).

c) To estimate the error between f(x) and its partial sum g(x) given by the sum of the first four nonzero terms of the power series, we can use the Lagrange form of the remainder

|R4(x)| = |f(x) - g(x)| ≤ M |x|^5 / 5!

a) To find the power series for f(x) about x = 0, we can use the Maclaurin series formula

f(x) = Σ[n=0 to ∞] (fⁿ(0)/n!) xⁿ

where fⁿ(0) denotes the nth derivative of f evaluated at x=0.

In this case, we have

f(x) = e^6(-2x^2)

fⁿ(x) = dⁿ/dxⁿ(e^6(-2x^2)) = (-2)^n(2x)^ne^6(-2x^2)

So, we can write the power series as

f(x) = Σ[n=0 to ∞] ((-2)^n(2x)^n e^6(0))/n!)

= Σ[n=0 to ∞] ((-2)^n (2x)^n /n!)

To find the first four nonzero terms, we substitute n = 0, 1, 2, and 3 into the above formula

f(0) = e^6

f'(0) = 0

f''(0) = 24

f'''(0) = 0

So, the first four nonzero terms of the power series are:

e^6 - 2x^2 + (2x^4)/2! - (2x^6)/3!

The general term of the power series is

(-2)^n (2x)^(2n) / (2n)!

b) To find the interval of convergence of the power series, we can use the ratio test

lim [n→∞] |((-2)^(n+1) (2x)^(2n+2) / (2n+2)! ) / ((-2)^n (2x)^(2n) / (2n)!)|

= lim [n→∞] |-4x^2/(2n+1)(2n+2)|

= lim [n→∞] 4x^2/(2n+1)(2n+2)

Since this limit depends on the value of x, we need to consider two cases

i) If x = 0, then the power series reduces to the constant term e^6, and the interval of convergence is just x=0.

ii) If x ≠ 0, then the series converges absolutely if and only if the limit is less than 1 in absolute value

|4x^2/(2n+1)(2n+2)| < 1

This is true for all values of x as long as n is sufficiently large. So, the interval of convergence is the entire real line (-∞, ∞).

c) We can use the Lagrange form of the remainder to estimate the error between f(x) and its partial sum g(x) given by the sum of the first four nonzero terms of the power series

|R4(x)| = |f(x) - g(x)| ≤ M |x|^5 / 5!

where M is an upper bound for the fifth derivative of f(x) on the interval [-0.6, 0.6].

The tube rests on a 1.5-mm thin film of oil having a viscosity of mu = 0.0586 N middot s/m^2. If the tube is rotating at a constant angular velocity of omega = 4.5 rad/s, determine the torque T that must be applied to the tube to maintain the motion. Assume the velocity profile within the oil is linear.

Answers

As per the given velocity, the torque T that must be applied to the tube to maintain the motion is zero.

To determine the torque required to maintain the motion of the tube, we can use the formula for torque:

T = I x α

where T is the torque, I is the moment of inertia, and α is the angular acceleration.

The angular acceleration is given by:

α = (d² θ) / (dt²)

where θ is the angle of rotation and t is time.

Since the velocity profile is linear, we know that the velocity of the oil can be described by:

v = (δ v / δ y) x y

where v is the velocity of the oil, δ v is the change in velocity across the oil layer, δ y is the thickness of the oil layer, and y is the distance from the bottom of the oil layer.

We can use this equation to determine the velocity of the oil at the top of the oil layer, which is where the tube is in contact with the oil.

v = (δ v / δ y) x y

v = (δ v / 1.5 x 10^⁻³) x 1.5 x 10⁻³

v = δ v

Therefore, the velocity of the oil at the top of the oil layer is equal to the change in velocity across the oil layer.

Now, we can use the velocity of the oil to determine the angular acceleration of the tube.

α = (d² θ) / (dt²)

α = (d/dt) (σ)

α = 0

Since the angular velocity is constant at omega = 4.5 rad/s, the angular acceleration is zero.

Therefore, the torque required to maintain the motion of the tube is:

T = I x α

T = 0

The mixed numbers that have 12 as the LCD are 2 11/12 and 6 4/5. All other fractions do not have 12 as the denominator and are not equivalent.

What are mixed numbers?

Mixed numbers consist of a whole number and a fractional part. To add or subtract mixed numbers, the fractions must have the same denominator (the bottom number of the fraction).

The LCD (lowest common denominator) is the smallest number that all of the denominators can be divided into evenly. In this case, the LCD is 12.

2 11/12 and 6 4/5 both have 12 as the denominator. The denominator of 11/12 can be divided by 11 and 12, so it is the same as 12/12. The denominator of 4/5 can be divided by 4 and 12, so it is the same as 48/12 (4 x 12 = 48). Therefore, both fractions have the same denominator.

The other fractions do not have 12 as their denominator. 3 1/7 can be divided by 3, 7, and 12, so it is the same as 21/12 (3 x 7 = 21). 5 3/4 can be divided by 4, 5, and 12, so it is the same as 60/12 (4 x 5 = 60). 8 38/47 can be divided by 8, 47, and 12, so it is the same as 376/12 (8 x 47 = 376).

Answer:

Step-by-step explanation:

To solve this problem, we can use the formula for the Pythagorean theorem, which states that for any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we are given the length of two sides of the triangle (the legs) and we need to find the length of the hypotenuse.

Let's label the sides of the triangle:

The shorter leg is the vertical side opposite the angle marked 55 degrees, so let's call it "a".

The longer leg is the horizontal side adjacent to the angle marked 55 degrees, so let's call it "b".

The hypotenuse is the side opposite the right angle, so let's call it "c".

Using trigonometry, we can determine the value of "a" and "b":

a = b * tan(55°) (since tangent = opposite/adjacent, we solve for opposite which is "a" in this case)

a = 100 * tan(55°) = 100 * 1.428 = 142.8

b = 100

Now, we can use the Pythagorean theorem to find the length of the hypotenuse:

c^2 = a^2 + b^2

c^2 = 142.8^2 + 100^2

c^2 = 20484.84 + 10000

c^2 = 30484.84

c = sqrt(30484.84)

c ≈ 174.6

Therefore, the length of the hypotenuse is approximately 174.6 units (the units are not given in the problem, but we can assume they are consistent with the units used for the given values of "a" and "b").

The problem does not specify the orientation or scale of the graph, but we can assume that it is a right triangle with the angle marked 55 degrees in the upper left corner.

The vertical side (the shorter leg) of the triangle should be labeled with a length of approximately 142.8 units (assuming the units used for the problem are consistent with the values given for "a" and "b"). The horizontal side (the longer leg) should be labeled with a length of 100 units.

The hypotenuse (the side opposite the right angle) should be drawn as a diagonal line connecting the endpoints of the vertical and horizontal sides. The hypotenuse should be labeled with a length of approximately 174.6 units.

The angle marked 55 degrees should be labeled as such, and the other two angles of the triangle (the right angle and the angle opposite the longer leg) should be labeled accordingly.

An algebraic expressiοn is a cοntains οf variables, cοnstants, and mathematical οperatiοns such as additiοn, subtractiοn, multiplicatiοn, divisiοn, and expοnentiatiοn. It cantains  parentheses and οther grοuping symbοls tο indicate the οrder in which the οperatiοns shοuld be perfοrmed.

In the given question ,

To find (f+g)(x),

we simply add the two functions f(x) and g(x) term by term:

(f+g)(x) = f(x) + g(x)

= (x² + 3x - 8) + (-2x + 6)

= x²  + (3x - 2x) + (-8 + 6)

= x² + x - 2  

Therefore, (f+g)(x) = x² + x - 2.

To find (f-g)(x), we subtract g(x) from f(x) term by term:

(f-g)(x) = f(x) - g(x)

= (x²  + 3x - 8) - (-2x + 6)

= x²  + (3x + 2x) + (-8 - 6)

= x²  + 5x - 14  

Therefore, (f-g)(x) = x²  + 5x - 14.

Answer this imagine please

Answers

Answer:

B) Group 2

Step-by-step explanation:

Group 1 wrote it correctly because there are 3 groups of 4x and 3 groups of 3

Group 2 wrote it incorrectly because that would mean 9 groups of 4x, which is not the case here

Group 3 wrote it correctly because 3(4x) + 3(3) = 3(4x+3) due to the Distributive Property

Group 4 wrote it correctly because it is an expansion of Group 3's expression

use the method of lagrange multipliers to find the minimum value of f subject to the given constraint. f(x,y)

Answers

The minimum value of f subject to the given constraint is -62.42 (abs min).

We need to find the minimum and maximum values of f(x,y) = 2x-5y subject to the constraint g(x,y) = x2+3y2 = 111.

Using Lagrange multipliers, we solve the equations:

∇f= λ∇g and g(x,y)  = 111.

This gives,

2 = λ2x    (1) equation.

-5 = λ6y   (2) equation.

From (1) we have λ=1/x. Substituting this into (2)

we have x=-6y/5 (3).

By substituting (3) into constraint g(x,y) we have

                     (-6y/5)2+3y2 = 111

                   y2(-36/25 + 3) = 111

                                         y = ±5√37/√13.

We have given some corresponding points in question (-6√37/√13, 5√37/√13) and (6√37/√13, -5√37/√13).

Evaluating f at these critical points:

f(-6√37/√13, 5√37/√13)

= 13√37/√13

≈ -62.42 (abs min)

f(6√37/√13, -5√37/√13)

=  37√37/√13

≈ 62.42  (abs max)

Answers

The cost of each item would be = $1.5 each of cup of coffee and donuts.

How to calculate the cost of each item bought by Michael?

For yesterday, the number of donut he ordered = 6

The number of cup of coffee he ordered = 8cup

Total cost = $21

The total number of items he ordered = 6+8 = 14

The cost for donuts alone,

= 6/14× 21/1

= 126/14

= $9

The cost of each donut = 9/6 = $1.5

The cost of cup of coffee ;

= 8/14× 21/1

= 168/14

= 12

for each cup of coffee;

= 12/8

=$1.5

Todd is traveling to Mexico and needs to exchange $390 into Mexican pesos. If each dollar is worth 12.29 pesos, how many pesos will he get for his trip?

Answers

To find out how many pesos Todd will get for his trip, we need to multiply the amount of dollars he has by the exchange rate of dollars to pesos.

First, we can set up the equation:

390 dollars x 12.29 pesos/dollar = ?

Then, we can simplify by multiplying:

= 4,794.1 pesos

Therefore, Todd will get 4,794.1 pesos for his trip.

If two objects are pushed by the same amount of force, the one with the greater mass will move more slowly. For a science project, Kendra used centimeter cubes, each with the same mass and volume, to build the two rectangular prisms shown. If each rectangular prism is pushed by the same amount of force, which one will move more slowly? Compare the volumes using
> or <?

Answers

Both rectangular prisms  will move at the same speed and volume of A > volume of B

What is rectangular prism ?

A rectangular prism is a three-dimensional solid shape that consists of six rectangular faces. It is also known as a rectangular cuboid, and it is a special case of a parallelepiped, which is a six-faced polyhedron where each face is a parallelogram. The rectangular prism has parallel and congruent rectangular bases that are connected by rectangular faces that are perpendicular to the bases.

The rectangular prism has several important properties. One of the most important is its volume, which is given by the formula V = lwh, where l is the length, w is the width, and h is the height of the rectangular prism.

Comparing their masses and volumes.
If the mass is the same for both rectangular prisms, then they will move at the same speed if pushed by the same amount of force. The mass of an object is a measure of the amount of matter it contains, and since both prisms have the same mass, they contain the same amount of matter. The force required to move an object is proportional to its mass, so if both objects have the same mass, they will require the same amount of force to move. Therefore, they will move at the same speed.

We can compare their volumes using the inequality sign:

volume of A > volume of B

This is because the area of the base of A is greater than the area of the base of B, and the height of A is less than the height of B. So, A has a greater volume than B.
