3. The horizontal distance "d" of the tip of a pendulum from its
vertical position at rest can be represented by a sinusoidal function.
The tip of the pendulum has a maximum displacement of 7.5 inches
and completes one cycle in 3.1 sec. Assume that the pendulum is at
rest at t= 0 and swings forward first.

Determine the value of y when t = 3.1 s:_

Approximate the value of t when y = 4 for the second time:

Answers

Answer 1

The second time that d = 4 is approximately 2.275 seconds after the pendulum starts swinging forward from its vertical position at rest.

What is the sinusoidal function?

A sinusoidal function is a mathematical function that describes a repetitive oscillation that resembles a sine or cosine wave. It can be expressed in the general form:

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

We can use the general form of a sinusoidal function to model the horizontal distance "d" of the tip of the pendulum from its vertical position at rest:

d = A sin(ωt + φ) + C

where:

A = amplitude (maximum displacement) = 7.5 inches

ω = angular frequency = (2π)/T, where T is the period = 3.1 seconds

φ = phase shift (initial horizontal displacement) = 0 (since the pendulum is at rest at t=0)

C = vertical displacement = 0 (since the pendulum is at rest at its vertical position)

Plugging in the given values, we get:

d = 7.5 sin((2π/3.1)t)

Now we can use this equation to answer the given questions:

Determine the value of d when t = 3.1 s:

We simply plug in t = 3.1 into the equation:

d = 7.5 sin((2π/3.1)(3.1))

d = 7.5 sin(2π)

d = 0 inches

Therefore, when t = 3.1 seconds, the horizontal distance of the tip of the pendulum from its vertical position is 0 inches.

Approximate the value of t when d = 4 for the second time:

To find when d = 4 for the second time, we need to find the two values of t for which the sinusoidal function equals 4. We can use the fact that the sine function repeats itself every 2π radians to solve this problem.

First, we find the period of the sinusoidal function:

T = 2π/ω = 2π/(2π/3.1) = 3.1 seconds

Next, we find the time it takes for the function to complete half a cycle, or π radians:

t1 = (π/ω) + kT, where k is an integer

t1 = (π/(2π/3.1)) + k(3.1)

t1 = (3.1/2) + 3.1k

We want to find the second time that d = 4, so we need to find the smallest integer value of k for which t2 > t1, where t2 is the time when d = 4 for the second time.

t2 = (3π/ω) + kT

t2 = (3π/(2π/3.1)) + k(3.1)

t2 = (9.3/2) + 3.1k

We want to find the smallest integer value of k such that t2 > t1 and d = 4:

7.5 sin((2π/3.1)t1) = 4

7.5 sin((2π/3.1)t2) = 4

calculating

t1 ≈ 0.604 s

t2 ≈ 2.275 s

Therefore, the second time that d = 4 is approximately 2.275 seconds after the pendulum starts swinging forward from its vertical position at rest.

The length of a rectangle is given by the function 1(x) = 2x + 1, and the width of the rectangle is given by
function w(x) = x +4.
Which function defines the area of the rectangle?
Hint: A = 1- w
O a(z)=2x² + 9x +4
O a(z)=2x² + 5x +4
O a(z)=2-3
O a(z) = 3r+5

Answers

The correct function that defines the area of the rectangle is:

A(z) = 2[tex]x^{2}[/tex]+ 9x + 4 (option A).

HOW TO CALCULATE AREA OF THE RECTANGLE?

The area of a rectangle is given by the product of its length and width. So, the function that defines the area of the rectangle would be:

A(x) = l(x) * w(x)

where l(x) is the length of the rectangle given by the function 1(x) = 2x + 1, and w(x) is the width of the rectangle given by the function w(x) = x + 4.

Substituting the given functions for length and width, we get:

A(x) = (2x + 1) * (x + 4)

Now, we can expand and simplify the expression:

A(x) = [tex]2x^2 + 8x + x + 4[/tex]

A(x) = [tex]2x^2 + 9x + 4[/tex]

72° (x+4)° Write an equation that can be used to find the value of x.​

Answer:

In a triangle, the sum of the interior angles is 180 degrees. So, we can set up the following equation:

72° + (x+4)° + A = 180°

where A is the measure of the third angle in the triangle.

Simplifying the equation, we get:

(x+4)° + 72° + A = 180°

x + 76° + A = 180°

Subtracting 76° from both sides, we get:

x + A = 104°

Therefore, an equation that can be used to find the value of x is x + A = 104°, where A is the measure of the third angle in the triangle. Note that we do not have enough information to solve for x or A individually, but we can use this equation to relate the two angles in the triangle.

Answers

Answer:

Step-by-step explanation:

To find P * 1, we need to find all pairs of elements in P that have a difference of 1. Let's start by listing the elements of P:

P = {(1, 2), (2, 5), (3, 8), (4, 11)}

Now, we can find all pairs of elements in P that have a difference of 1:

(1, 2), (2, 5) -> (1, 5)

(2, 5), (3, 8) -> (1, 3)

(3, 8), (4, 11) -> (1, 3)

Therefore, P * 1 = {(1, 5), (1, 3), (1, 3)} = {(1, 5), (1, 3)} (since the last pair is a duplicate).

​​Part A:
Find D(15) and interpret the meaning in the context of the problem.

Answers

To find D(15), we simply substitute t = 15 into the function:

D(15) = 2,280 - 60(15)

D(15) = 2,280 - 900

D(15) = 1,380

Therefore, when the Chang family has been driving for 15 hours, they are 1,380 miles away from home.

Interpreting this result in the context of the problem, we can say that the family has made good progress on their trip and has covered a distance of 1,380 miles from home.

WZ and XR are diameters find the measure of XZ in circle C

Answers

The length of XZ in circle C is equal to the √34. This can be found using the Pythagorean theorem and the fact that XZ is a radius of the circle.

As WZ and XR are diameters, they intersect at the center of the circle, which we'll call point O.

Since WX is a chord of the circle, we can use the perpendicular bisector of WX, which passes through O, to find the length of XZ.

Let's call the midpoint of WX point M. Then OM is perpendicular to WX and bisects it.

So we have two right triangles, OXM and MXZ. We know that OM = 5 and XM = 3 (half of WX).

Using the Pythagorean theorem, we can find the length of OX:

OX² = OM² + MX²

OX² = 5² + 3²

OX² = 34

OX = √(34)

Since XZ is also a radius of the circle, we have XZ = OX = √(34).

Therefore, the measure of XZ in circle C is √(34).

The distribution of the heights of students in a large class is roughly Normal, with an average height of 68 inches, and approximately 95% of the heights are between 62 and 74 inches.

The height distribution is approximately Normal, we can use the empirical rule, which states that approximately 95% of the data falls within 2 standard deviations of the mean, to estimate the standard deviation.

The range of heights within which approximately 95% of the students fall is from 62 to 74 inches.

This range is 12 inches wide, and it corresponds to 2 standard deviations from the mean.

What is the center and radius of the circle?

To rewrite the equation of the circle in graphing form, we need to complete the square for both the x and y terms.

x² + 6x + y² - 4y = -9

Step 1: Move the constant term to the right side of the equation.

x² + 6x + y² - 4y + 9 = 0

Step 2: Group the x terms and the y terms separately.

(x² + 6x) + (y² - 4y) + 9 = 0

Step 3: Complete the square for the x terms. To do this, take half of the coefficient of x (which is 6), square it, and add and subtract it inside the parentheses.

(x² + 6x + 9 - 9) + (y² - 4y) + 9 = 0

(x + 3)² - 9 + (y² - 4y) + 9 = 0

(x + 3)² + (y² - 4y) = 0

Step 4: Complete the square for the y terms. To do this, take half of the coefficient of y (which is -4), square it, and add and subtract it inside the parentheses.

(x + 3)² + (y² - 4y + 4 - 4) = 0

(x + 3)² + (y - 2)² - 4 = 0

Step 5: Move the constant term to the right side of the equation.

(x + 3)² + (y - 2)² = 4

The equation is now in graphing form, which is:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

Comparing the equation to the graphing form, we see that the center of the circle is (-3, 2) and the radius is 2. Thus, the graph of the circle is centered at (-3, 2) with a radius of 2.

If the length of a rectangle prism is doubled, it’s width is tripled, and it’s height remains the same, what is the volume of the new rectangle prism?

Answers

If in a rectangular-prism, the length is doubled, width is tripled and height is same, then the volume of new rectangular prism will be 6 times the original-prism.

The "Volume" of a 3-D object is defined as the amount of space that object occupies in three-dimensional space. It is a measure of the total capacity or size of the object

Volume of a rectangular prism is ⇒ Volume = Length × Width × Height,

If the length of the rectangular prism is doubled, the new length would be 2 times the original length.

If the width is tripled, the new width would be 3 times the original width, and

If the height remains the same, it would be the same as the original height.

Let the original length be = "L",  width be = "W", and height be = "H",

So, New Length = 2L , New Width = 3W, New Height = H (remains unchanged),

So, volume of new rectangular prism is :

New Volume = (New Length)×(New Width)×(New Height),

⇒ (2L) × (3W) × H

⇒ 6LWH

Therefore, volume of "new-rectangular prism' is 6 times volume of  original rectangular prism.

Answers

The amount of space in a gift box for earrings would typically be measured in cubic inches (C).

how to solve the question?

Cubic inches is a unit of volume that is commonly used to measure the capacity of small, enclosed spaces like boxes, containers, and packaging. It is defined as the volume of a cube that measures one inch on each side.

For a gift box designed to hold earrings, the volume of the box would need to be sufficient to accommodate the size of the earrings and any additional padding or decorative elements. Since earrings are small, the gift box would likely have a small volume, measured in cubic inches.

Other units of measurement, like square meters or yards, are used to measure the area of two-dimensional surfaces like floors, walls, or yards. Square centimeters are also a unit of area measurement, but they are much smaller than square meters or yards, and may be used to measure the surface area of small objects.

Cubic feet is a larger unit of volume measurement that may be used for larger boxes or containers, like shipping crates or storage bins. However, for a gift box designed specifically for earrings, cubic inches is likely the most appropriate unit of measurement.

Answers

Let's assume the total mass of the chemical in the container is "x" grams.

According to the problem statement, the sample taken out was 4(1)/(4) grams less than (1)/(5) of the total mass of the chemical in the container.

So we can write an equation as follows:

37.8 = (1/5)x - 4(1/4)

Let's solve for "x" to find the total mass of the chemical in the container:

37.8 + 4(1/4) = (1/5)x

37.8 + 1 = (1/5)x

38.8 = (1/5)x

x = 38.8 x 5

x = 194 grams

[tex]x^2 + y^2 = 17^2[/tex]

Differentiating implicitly with respect to time, we get:

[tex]2x(dx/dt) + 2y(dy/dt) = 0[/tex]

Substituting the given values, we get:

[tex]2x(dx/dt) + 2(16)(-2) = 0[/tex]

Simplifying, we get:

[tex]2x(dx/dt) = 64[/tex]

Dividing both sides by 2x, we get:

dx/dt = 64/(2x)

We know that y = 16, so we can use the Pythagorean theorem to solve for x:

[tex]x^2 + 16^2 = 17^2x^2 = 17^2 - 16^2x^2 = 33[/tex]

Taking the square root, we get:

[tex]x = sqrt(33)[/tex]

Substituting this into our expression for dx/dt, we get:

[tex]dx/dt = 64/(2*sqrt(33)) ≈ 3.86 ft/s[/tex]

Therefore, when the top of the ladder is 16 feet above the ground, the foot of the ladder is moving away from the wall at a speed of approximately 3.86 feet per second.
