• ### Characteristics of West African Dance?

What are the characteristics of West African Dance? What about the West African Welcoming Dance? What kind of movement? Hip, arm, full-body? How is the movement? Quick and sharp or light and floaty etc.?

Can anyone describe the Ijesha Dance by Clyde Morgan specifically? Thanks in advance!!!! 10pts for the best answer!

• ### Pimple on pubic area?

Is this normal? How do I get rid of it? I'm a virgin so the idea that it's an STI or an STD is off the list as far as I know.

Does anyone have any solutions for this? It doesn't really bother me that much but it's strange and it doesn't seem to be like warts or anything. Though I've had a wart before on my neck, close to my ear. I don't think it's the same thing though. I'm fairly sure it's just a pimple- what do you think?

It feels like a pimple and is sorta pink but not really. (I can't really see the color correctly since I have a lot of hair down there...) Sorry for all the details.

• ### AB Calculus problems help?

Let f be a function that is differentiable on the

open interval (1,10). If f(2) = −5, f(5) = 5,

and f(9) = −5, which of the following must

be true?

I) f has at least 2 zeros.

II) The graph of f has at least one horizontal tangent.

III) For some c, 2 < c < 5, f(c) = 3

______________________________________…

The function f given by f(x) = x^3 + 12x -24 is:

1. increasing for x < −2, decreasing for

−2 < x < 2, increasing for x > 2

2. decreasing for x < −2, increasing for

−2 < x < 2, decreasing for x > 2

3. decreasing for all x

4. decreasing for x < 0, increasing for x > 0

5. increasing for all x

• ### Related Rates Calculus help?

In which the angle beta increases at a constant

rate of 12 radians per minute. At what rate is

x increasing in units per minute when x = 12

units?

(the diagram is a right triangle with 20 as the hypotenuse and "x" as the y-axis) Angle beta is between the hypotenuse and side "y" (x-axis)

• ### Can someone help me with citing a Scientific Journal? (Easy bib does not work in this case.)?

http://www.molecularneurodegeneration.com/content/...

I have to find the volume number and the pages it's from but I don't know where I can find that!

• ### How do I do these pre-calc problems?

Use an appropriate half-angle formula to find the each value of the expression.

1) cos(pi/12)

2) sin(9pi/8)

Please explain! I would rather have a detailed explanation as opposed to the answer. Thanks in advance!

• ### What is the secret to creating awesome A Capella harmonies?

Is there is special formula? Thrids? Fifths? Anything you would like to suggest for creating harmonies? Thanks!

For what value of k does the equation: x^2 + 3x -k = 0 have equal roots?

Can someone explain how to do this? And, what is an equal root? Thanks in advance!

• ### Probability math problem- help please?

What is the probability of getting exactly one head from 3 coin tosses?

• ### Physics question help!?

A flowerpot is knocked off a balcony 19.3 m

above the sidewalk and falls toward an un-

suspecting 1.66 m tall man who is standing

below.

How close to the side walk can the flower

pot fall before it is too late for a warning

shouted from the balcony to reach the man in

time? Assume that the man below requires

0.313 s to respond to the warning, and the

velocity of sound in air to be 342 m/s. The

acceleration of gravity is 9.8 m/s2 . Answer in

units of m.

If tan (theta/2) = 1/3; what is the exact value of tan(theta)?

A parallelogram has sides of 6in and 8in and included angle of 60: Find

i) it's area

ii) the length of each diagonal

[I think I'm supposed to use the law of sines (you know.. the one with proportions) but I don't know the angles of the diagonal]

write as a sum of cosines: 2cos(60)cos(120)

Please provide an explanation and which properties you used (i.e.: sum of cosine etc..) Thanks in advance!

• ### Pre-calculus problems! Help please?

The following questions are not for homework but are questions that my teacher gave as a guide to study for our upcoming test. With that said, I'm not interested in the answer but I am interested in the methods to how you arrived to the answer. We have learned about the sum of angles, difference of angles, double angle identities and half-angle identities. Please answer any of the following problems to the best of your ability! Thanks in advance!!

1. If tan (theta/2) = 1/3; what is the exact value of tan(theta)?

2. A parallelogram has sides of 6in and 8in and included angle of 60: Find

i) it's area

ii) the length of each diagonal

3. write as a sum of cosines: 2cos(60)cos(120)

4. Write as a sum of sines 2sin(10theta)cos(6theta)

5. Evaluate exactly cos(40)+cos(80)+cos(160)

So, I did the first problem but I couldn't figure out the second and they are connected. Can anyone please help?

Assume your mass is 60 kg. The acceleration

due to gravity is 9.8 m/s2.

How much work against gravity do you do

when you climb a flight of stairs 3.7 m high?

2175.6 <<<< this is the answer for the first question

Consider the energy consumed by a 60 W

light bulb in an hour.

How many flights of stairs would you have

to climb to equal the work of the lightbulb?

• ### Physics question! Help Please?

So, this is a 2 part question and I have the answer for the first one but I don't know how to do the 2nd part.

A car with an initial speed of 21.3 km/h ac-

celerates at a uniform rate of 0.89 m/s2 for 3.4

s.

a) Find the final speed of the car. Answer

in units of m/s.

b) Find the displacement of the car after that

time. Answer in units of km.

So, this is a 2-part question and I figured out the first part but I couldn't figure out the 2nd part. Please help?

and accelerates at a maximum rate of −5.4

m/s2.

a) From the instant the plane touches the

runway, what is the minimum time needed

before it can come to rest? Answer in units of

s.

21.07407407 <<<<<< That's the answer to the first part.

The plane is landing on a naval aircraft carrier

that is 0.80 km long.

b) What distance does the plane require to

land? Answer in units of km.
