use spherical coordinates to find the mass of the sphere x^2+y^2+z^2=9 if its density at a point is proportional to the disitance from the point to the origin.

please show me the solution, i already spent an hour on this fking questions and still not understanding very well. it's important

when i purchase item on amazo, how do i know it's from amazon or third party sellers? does the item have amazon prime means from amazon? it's important because when i received a defective item, it's easily to get the refund without shipping the item back. :P (sometimes)

The function

x = (4.2 m) cos[(3πrad/s)t + π/2 rad]

gives the simple harmonic motion of a body. At t = 1.8 s, what are the (a) displacement, (b) velocity, (c) acceleration, and (d) phase of the motion? Also, what are the (e) frequency and (f) period of the motion?

i need the answer btw

The Quiet Life

by Alexander Pope (1688-1744)

Read by Samuel West

Happy the man whose wish and care

A few paternal acres bound,

Content to breathe his native air

In his own ground.

Whose herds with milk, whose fields with bread,

Whose flocks supply him with attire;

Whose trees in summer yield him shade,

In winter fire.

Blest who can unconcern’dly find

Hours, days, and years slide soft away

In health of body, peace of mind,

Quiet by day,

Sound sleep by night; study and ease

Together mixt, sweet recreation,

And innocence, which most does please

With meditation.

Thus let me live, unseen, unknown;

Thus unlamented let me die;

Steal from the world, and not a stone

Tell where I lie.

The Golden age in Greece ended with a war in Sicily? True or F?

Sophocles was also noted for his dance and music talents;once he dance after a victory in the nude with no instruments

As we know Sophocles is born 498 BC and died 406 BC. But im so confused did he live in the 5th century?

The sheltering sky

Knows not what is to come,

But what is.

The blazing sun

Lights all that is,

But cannot reach what is not.

The rain from the heavens

Quenches the thirst of all living creatures,

But cannot satisfy those who have not yet came into being.

All of nature lives in the present

And knows naught of the future,

For the present is all that is real

And the future is but a shadow of what is to come.

I don t understand poems, can someone just tell me what is the meaning of this poem? or the elements of this poem

i don't know how to write the summary of results, my professors said each measured quantity must include your estimate of errors. what is that mean? should i do some calculation?

A boat is traveling upstream at 10 km/h with respect to the water of a river. The water is flowing at 7.0 km/h with respect to the ground. What are the (a) magnitude and (b) direction of the boat’s velocity with respect to the ground? A child on the boat walks from front to rear at 6.0 km/h with respect to the boat.What are the (c) magnitude and (d) direction of the child’s velocity with respect to the ground?

I know how to do this question, but i don't get why is the water is flowing with respect to the ground is negative?

does it always been negative direction?

i had a test in my literature class, and it asked me where did Saul and David from, I answered Benjamin for Saul but i don't know about David. please help

and it also asked how did Saul die.

How did Saul die?

Where did Saul and David from? (countries)

My math skills is ok I think . Currently I'm taking cal 3 class and college physics 1.but physics class is totally different with math. First, I don't well-understanding to solving a problem, i just know the formula and use the data that the problem gave us to fit in the formula. Whenever the question change little bit , I wouldn't know how to do it. And I'm so confused about the elements such as velocity, acceleration and average of velocity and acceleration. Whenever I get in my physics class I'm feeling like I enter another world. Did I miss some class that teach basic physics? I don't mean I didn't learn anything from my physics class, but im just saying like... I don't know how to describe. Sigh

I‘’m so regret that I took the English literature class when I‘’m studying math major, this class just having lot of reading ，old English vocabulary and weird grammar. I just took a test today, I think I will get the worst score in the class. I‘’m so frustrate, I‘’m afraid I wouldn’t get a good grade from this class.
