Consider the following vector function. R(t) = 9 2 t, e9t, e−9t (a) find the unit tangent and unit normal vectors t(t) and n(t)

Answers

The unit tangent vector is T(u) and the unit normal vector is N(t) if the  vector function. R(t) is equal to 9 2 t, e9t, e−9t.

What is vector?

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have vectored function:

[tex]\rm R(t) = (9\sqrt{2t}, e^{9t}, e^{-9t})[/tex]

Find its derivative:

[tex]\rm R'(t) = (9\sqrt{2}, 9e^{9t}, -9e^{-9t})[/tex]

Now its magnitude:

[tex]\rm |R'(t) |= \sqrt{(9\sqrt{2})^2+ (9e^{9t})^2+ (-9e^{-9t})^2}[/tex]

After simplifying:

[tex]\rm R'(t) = 9 \dfrac{e^{18t}+1}{e^{9t}}[/tex]

Now the unit tangent is:

[tex]\rm T(u) = \dfrac{R'(t)}{|R'(t)|}[/tex]

After dividing and simplifying, we get:

[tex]\rm T(u) = \dfrac{1}{e^{18t}+1} (\sqrt{2}e^{9t}, e^{18t}, -1)[/tex]

Now, finding the derivative of T(u), we get:

[tex]\rm T'(u) = \dfrac{1}{(e^{18t}+1)^2} (9\sqrt{2}e^{9t}(1-e^{18t}), 18e^{18t}, 18e^{18t})[/tex]

Now finding its magnitude:

[tex]\rm |T'(u) |= \dfrac{1}{(e^{18t}+1)^2} (9\sqrt{2}e^{9t}(1-e^{18t})^2+ (18e^{18t})^2+( 18e^{18t})^2)[/tex]

After simplifying, we get:

[tex]\rm |T'(u)|= \dfrac{9\sqrt{2}e^{9t}}{e^{18t}+1}[/tex]

Now for the normal vector:

Divide T'(u) and |T'(u)|

We get:

[tex]\rm N(t) = \dfrac{1}{e^{18t}+1} ( 1-e^{18t}, \sqrt{2}e^{9t}, \sqrt{2}e^{9t})[/tex]

Thus, the unit tangent vector is T(u) and the unit normal vector is N(t) if the  vector function. R(t) is equal to 9 2 t, e9t, e−9t.

Raj, Devi and Miko have managed their savings well. The sum of Raj and Devi's savings is $1181. Raj and Miko's savings sum up to $1797. The ratio of Devi to Miko's savings is 3 : 11. How much has Raj saved?

Answers

Answer:

it is easy it is 3833

Step-by-step explanation:

The money saved by Raj from the given conditions is $950.

Given that, Raj, Devi and Miko have managed their savings well.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The ratio of Devi to Miko's savings is 3:11.

So, Devi's saving is 3x and Devi to Miko's savings is 11x.

The sum of Raj and Devi's savings is $1181. Raj and Miko's savings sum up to $1797.

Let y be the Raj's saving.

Now, y+3x=1181 --------(I) and y+11x=1797 --------(II)

From equation (I), y=1181-3x

Substitute y=1181-3x, in equation (II), we get

1181-3x+11x=1797

⇒ 8x=1797-1181

⇒ 8x=616

⇒ x=616/8

⇒ x=77

So, y=1181-3x=1181-231

=$950

Hence, the money saved by Raj from the given conditions is $950.

Each donut has a diameter of 3 inches and a height of 1.5 inches. The donuts in the original box stood on their side. You have been asked to design a new box that will allow the donuts to lie flat as shown. What is the circumference, in inches, of a donut?​

Answers

9.42 in. is the circumstance

The company has decided to redesign the box it uses to hold one dozen donuts, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

What is circumference?

The circumference is the distance around the edge of a circle or any circular object. It is calculated using the formula:

C = 2πr

To find the circumference of a donut, we need to first find the diameter. The diameter of each donut is 3 inches, so the radius is 1.5 inches. The circumference can then be found using the formula:

C = 2πr

where C is the circumference and π is approximately 3.14.

Substituting the radius, we get:

C = 2π(1.5) = 3π

Therefore, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

Which statement describes the function y = axn when a = 1 and n is odd?

Answers

Answer:

The graph is symmetric about the origin.

The graph does not pass through the origin.

Step-by-step explanation:

We're given:

the function y=axna = 1n is odd

Because a = 1, then the given function can be rewritten as y = n.

The graph opens down

The function y = n will produce a horizontal line. Any function in the form of y = a single number, such as 4 or 9.3 will produce a horizontal line.

The graph is symmetric about the origin.

This is true, given the graph is a horizontal line.

The graph does not pass through the origin.

This is also true. We're given that n is an odd number. The graph will only pass through the origin if n = 0, and 0 is even.

The graph has more than one x-intercept.

This would only be true when n = 0, and this isn't possible. So, no.

Find the total surface area of this cone, leaving your answer in terms of π

Answers

The total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².

What is a cone?

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The total surface area of a cone is given by its curved surface area plus area of its base.

Total surface area = curved surface area + area of base

Total surface area = πrl + πr²

Given that;

Radius r = 5cmSlant height l = 9cmTotal surface area TSA = ?

Total surface area = πrl + πr²

Total surface area = ( π ×  5cm × 9cm ) + ( π × (5cm)² )

Total surface area = 45πcm² + 25πcm²

Total surface area = 70πcm²

Therefore, the total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².

Can someone please answer this, ill give you brainliest Would be very appreciated.

Answers

Answer:

Given function:

f(t) = (-16t - 2)(t - 1)

Part 1

The zeros of the function are the values of t when f(t) = 0

⇒ f(t) = 0

⇒ (-16t - 2)(t - 1) = 0

⇒ (t - 1) = 0  ⇒  t = 1

⇒ (-16t - 2) = 0  ⇒ t = -2/16 = -1/8

Part 2

The zeroes tell us the time (in seconds) when the ball is at ground level (when its height is zero).

Since time is not negative, only one zero is meaningful:  t = 1

Therefore, the total journey of the ball, from throwing it to it hitting the ground, is 1 second.

Part 3

The height the ball is thrown can be determined by inputting t = 0 into the function:

⇒ f(0) = (-16(0) - 2)(0 - 1)

⇒ f(0) = (0 - 2)(0 - 1)

⇒ f(0) = (-2)(-1)

⇒ f(0) = 2

Therefore, the height from which the beach ball is thrown is 2 ft.

Equation: y = (-16t-2)(t -1)

1) Finding zeros of the function?

To find zero's of the function y = 0

(-16t-2)(t -1) = 0

-16t - 2 = 0, t - 1 = 0

t = 2/-16, t = 1

t = -0.125, 1

2) What do the zero's tell us? Are they meaningful?

Answer: It tells us that the time is 1 seconds when the height of the ball is 0 or at rest.

3) From what height is the ball thrown?

Insert t = 0

y = (-16(0)-2)((0) -1)

y = 2
