given that cosθ = 0.678 where 0<θ

Answers

Answer 1

Answer:

θ = 47.312447

Step-by-step explanation:

I assume you are trying to find θ

The first thing you do is to find θ is to do the acos of 0.678

θ = acos(0.678)

θ = 47.312447

The Goodsmell perfume company has a new line of perfume and is designing a new bottle for it. Because of
the expense of the glass required to make the bottle, the surface area must be less than 150 cm2. The
company also wants the bottle to contain at least 100mL of perfume. The design under consideration is in the
shape of a cylinder.
Determine the maximum volume possible for a cylindrical bottle that has a total surface area of less than 150
cm2 Determine the volume to the nearest 10mL. Report the dimensions of the bottle and the corresponding
surface are and volume.
This cylindrical perfume bottle needs to be boxed in a prism for sale on store shelves. The Goodsmell perfume
company would like a box with the smallest possible surface area which will contain your design for the
perfume bottle. Report the dimensions of the box and the corresponding area and volume.
The Pretty Perfume company, Goodsmell's competition, has also designed a new perfume bottle. The bottle is
to be a spherical shape with a diameter of 7cm. Determine the volume and surface area of this bottle.
The spherical bottle has a conical shaped lid with a diameter of 5cm and a height of 4.5cm. Given this
information, calculate the volume and surface area of the lid of the spherical shaped bottle.
Determine the dimensions of the smallest possible box which could be used to package Pretty Perfume's new bottle with its spherical bottle and conical-shaped
lid. However, this box is not shaped like a rectangular prism. Pretty Perfume would like to have unique packaging and have chosen to have a box shaped like a
pyramid. Calculate the volume and surface area of this pyramid-shaped box.

Prepare a written report that includes:
1. A clear and concise explanation of the process that you used to solve the problem.
2. The calculations that you made, presented in an organized fashion.

- Seats in a theater are curved from the front row to the back. The front row has 10 chairs, the second has 16 and the third has 22, and so on.
a) Write a recursive rule for this series:

b) Write an explicit rule for this series:

c) Using the explicit formula, find the number of chairs in row 5 (show work)

d) The auditorium can hold 17 rows of chairs. Write a sigma notation for this series, and then use either series formula to calculate how many chairs can fit in the auditorium.

Answers

Answer:

The series:

10, 16, 22, ...

This is an AP with the first term a₁ = 10 and common difference d = 6

a) Recursive formula:

a₁ = 10,aₙ = aₙ₋₁ + 6

b) Explicit formula:

aₙ = a₁ + 6(n - 1)  ⇒ aₙ = 10 + 6n - 6  ⇒ aₙ = 6n + 4

c) n = 5 ⇒ a₅ = ?

a₅ = 6*5 + 4 = 34

d) S₁₇ = ?

Sₙ = n(a₁ + aₙ)/2 = n(2a₁ + (n - 1)d)/2S₁₇ = 17(2*10 + 16*6)/2 = 986

Step-by-step explanation:

sn=15+(n-1)2

the 20th row n=20 so the seats are  

15+(20-1)(2)=53 seats

Explicit formula:

aₙ = a₁ + 6(n - 1)  ⇒ aₙ = 10 + 6n - 6  ⇒ aₙ = 6n + 4

Which method and why? Solve, shoving all work

Answers

Answer:

(2,-1)

Step-by-step explanation:

The ys in both questions are isolated on one side of the equation in both. The numerical coefficient of both is 1. Therefore you should equate the the left side of each equation to the other left side. The solution is the easiest one to solve because there is only 1 unknown on both sides.

4x - 9 = x - 3                      Subtract x from both sides.

4x-x - 9 = -3                       Combine

3x -9 = - 3                          Add 9 to both sides

3x - 9+9 = - 3+9

3x = 6                                Divide by 3

3x/3 = 6/3

x = 2

===============

Now use the second equation to solve for y

y = x - 3

y = 2 - 3

y = -1

==============

The solution is (2,-1)

22. Tell which line below is the graph of each equation in parts (a)-(d).

Step-by-step explanation:

Trigonometry Examples

Trigonometry

 

Find the Reference Angle (17pi)/10

17π1017π10

Since the angle 17π/ 10 is in the fourth quadrant, subtract 17π/10 from2π.

2π−17π/10

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].

What is coterminal angle?

Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Angles are considered to be in standard position if the initial side is on the positive x-axis and the vertex at the (0,0) point of the Cartesian plane. All angles generated that share the same terminal side are coterminal angles. These are angles that have differences of multiples of 360n or n2pi where n is an integer.

A coterminal angle is found by simply adding or subtracting 360 and its multiples.

The coterminal angles of 20 degrees for example are 20 + 360 = 380 or 20 - 360 = -340. This may continue by adding or subtracting 360 each time.

To get coterminal angles, you simply have to add or subtract 2[tex]\pi[/tex].

According to this problem,

We are looking for a coterminal angle that is between 0 to 2[tex]\pi[/tex], so we will add [tex]2\pi \ to \ \frac{-17\pi }{10}[/tex].

= [tex]\frac{-17\pi }{10} +\frac{20\pi }{10}[/tex]

= [tex]\frac{-17\pi +20\pi }{10}[/tex]

= [tex]\frac{3\pi }{10}[/tex]

Hence,

The angle between 0 to [tex]2\pi[/tex] that is coterminal with [tex]-\frac{17\pi }{10}[/tex] is [tex]\frac{3\pi }{10}[/tex].

What precisely is a triangle?

A triangle is a polygon because it includes four or so additional parts. It features a simple rectangular shape. A rectangle having edges A, B, and C is referred to as a triangle. When the sides are actually not collinear, Euclidean geometry yields a single plane and cube. If a triangle contains three parts and three angles, it is a polygon. The intersections of a triangle's three sides are referred to as its corners. The sum of a triangle's sides is 180 degrees.

by Pythagorean theorem

n = [tex]\sqrt{12^2 - 4^2}[/tex]

The cube root function , has no domain restrictions. The domain of the cube root function is all real numbers, or ℝ .

What is domain ?

The domain of a function is the complete set of possible values of the independent variable.

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero.

The number under a square root sign must be positive in this section.

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Domain: (- ∞ , ∞) , {x | x ∈ [tex]\mathbb{R}[/tex]}

Hence, The domain of the cube root function is all real numbers, or ℝ .
