may someone please help? thank you!

Answers

Answer:

[tex]6\sqrt2\\OR\\8.48528137[/tex]

Step-by-step explanation:

The area of a sector of a circle is found by:

[tex]A = \frac{\theta*r^2}{2}[/tex]

The question asks for the radius so the equation above can be repurposed

[tex]r = \sqrt\frac{2A}{\theta}[/tex]

A = 3pi

angle = pi/12

[tex]\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72[/tex]

[tex]\sqrt{72} = 6\sqrt2 = 8.48528137[/tex]

Answer:

  a) radius: 6 (m); mass: 22 (kg)

  b) volume: 19 (m³)

  c) d ≈ 2.8×10^3 kg/m³

Step-by-step explanation:

The order of magnitude is the exponent of 10 when the number is written in scientific notation.

a) radius: 1.6×10^6 m, so the order of magnitude is 6 when the units are meters.

  mass: 4.8×10^22 kg, so the order of magnitude is 22 when the units are kg.

__

b) The volume is ...

  V = (4/3)πr^3 ≈ 1.716×10^19 m^3, so the order of magnitude of the volume is 19 when the units are m^3.

__

c) The ratio of mass to volume is ...

  d = (4.8×10^22)/(1.716×10^19) ≈ 2.8×10^(22-19) = 2.8×10^3 kg/m^3, so the order of magnitude is 3 when the units are kg/m^3.

Find lateral surface
area of the play tent.
h = 4 in
14 in
5 in
5 in
W
6 in

Answers

Answer:

224 in.²

Step-by-step explanation:

The tent has a shape of a triangular prism. So, we are looking for the Lateral surface area of a triangular prism.

Lateral surface area of a triangular prism = Perimeter of base × height of prism

Perimeter of base = 5 + 6 + 5 = 16 in.

Height of prism = 14 in.

Plug in the values

Lateral Surface Area = 16 × 14 = 224 in.²

What is the total surface area ?

Answers

Answer:

The answer is 126.

There are only seven days left until we launch of our new product and we only have $668 left in our promotion budget we need to spend $85 on the last day can you please calculate how many dollars a day we can spin on the remaining days

Answers

Answer:

$97.17

Step-by-step explanation:

First, subtract 85 from 668:

668 - 85

= 583

This means that our budget for all of the days excluding the last day is $583

To find how much can be spent on the remaining days, divide 583 by 6:

583/6

= 97.17

So, approximately $97.17 can be spent on the remaining days

The Wells family uses up a

-gallon jug of milk every 3 days. At what rate do they drink milk?
Simplify your answer and write it as a proper fraction, mixed number, or whole number

Answers

Answer:

4 gallons/1 day

Step-by-step explanation:

What is a rate? A rate is writing a ratio in fraction form. A ratio is the proportion of two things. (ex: for every 1 dog, there are two cats.)

Creating the ratio: For the ratio, there is no given amount of which one needs  to come first, but because it is about the milk, I put that first. In the problem it says 12 gallons for 3 days so: 12/3

Simplifying: To simplify, think of the largest factor between the two numbers. If you can't immediately, think of one factor in common and keep simplifying. In this case, 4 is the greatest common factor between these. To simplify, divide both sides by four, and that is your answer: 4: 1

Given tan theta = -2 and pi/2 < theta < pi; find cos2theta.
a. - 4/3
b.- 4/5
c. 3/4
d. - 3/5

PLEASE HELP ASAP

Answers

Answer:

Cos 2theta = -3/5

Step-by-step explanation:

Given that;

tan theta = -2

tan theta = -2/1 = opp/adj

hyp^2 = (-2)^2+1^2

hyp = √4+1

hyp = √5

sin theta = opp/hyp

sin theta = -2/√5

Cos theta = adj/hyp

Cos theta = -2/√5

Cos 2theta = 1-2sin^2 theta

Cos 2theta = 1- 2(-2/√5)^2

Cos 2theta = 1- 2(4/5)

Cos 2theta = 1- 8/5

Cos 2theta = (5-8)/5

Cos 2theta = -3/5

Given f(x) = 5x4 – x2 + 6x – 1. What is Limit of f (x) as x approaches negative 1?

–3
–13
–25
–29

Answers

Answer:

-3

Step-by-step explanation:

The limit of the given function f(x) = 5[tex]x^{4}[/tex] – x2 + 6x – 1 approach negative 1 will be -3 so correct option will be (A).

What is limit?

Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.

In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.

Because the value of that function at that point doesn't define.

For example, limits tend to 0 of sine x, limits tend to infinite of cosx.

Given that the function

5[tex]x^{4}[/tex] – x2 + 6x – 1

Limit is from x is tends to -1

[tex]\lim_{x \to \-1} f(x)[/tex] = 5(-1)⁴ - (-1)² +6(-1) -1

⇒ -3 hence it will be the correct answer.
