For what values of x is the slope tangent to y=x^3+11x^2-x+17 equal to 0

Take the derivative  and set to 0

3x^2 + 22x - 1   = 0

Solving this gives us

x ≈ 0.045176      and   x ≈  -7.3785

melody, do you think you need to revise the instructions as i cant upload any pics...

i know,, i was joking...you see too serious , eh?

yay great!

It took forver,,, no wait.... it took... = 5:50-5:25 = 25 mins.....yep thats it!

hi, rosala! no, it does not require any payment don't worry! and thank you for voting and joining!

you know i did post a pic of the fig, but it didnt display it...i just saw that now after remebering, thanks for the fig hectictar, how did you upload it?

does it require money to join?

Hi , im rosala , and i want to join!

i guess Sunday and Saturday would be good!

I drew a picture just for fun :)

As a member, I'm voting for wed and sat.

You know its almost 2 am and i just got off from studying "Heredity and Evilotion" In BIo and i just thought to come here while having my midnight snack, then i now see your question and even tho ive done so much math in this week, i still want to answer you.....

so , as  the ball are next to each other, its fig, would be like... 

so here the height of cylinder (h)= 1.25x3 =3.75 inches

radius or cylinder = radius of ball = r= 1.75inches

V left in can = V of (can - 3b***s)

=Pi*r²h- 3* 4*Pi*r³/3

Its always to take common, makes the calculation easier...

=Pi*r²(h - 3*4r/3)

=22/7 * (1.75)² ( 3.75 - 12*1.75/3)

i guess you can do the rest yourself, 

just a tip: while solvinf such problem which have decimal quite a lot in them , its always better to take them in fraction , it makes the calculation easier and you are less prone to errors....

hope it helps.....

There is a formula for such an even number. Since 1,000,000 can be written as: 10^6, and we are excluding one number (7 in this case), then we only have 9^6 numbers left. The difference:

10^6 - 9^6 =1,000,000 - 531,441 =468,559 must be "sevens".

In a single-elimination tournament of 4 teams, 3 games will be played.

If there is a 50-50 chance that each team can win each game, then the probability of predicting the winning team in all three games is (1/2) x (1/2) x (1/2), or 1/8.

An ostrich egg has about the same volume as a sphere with a diameter of 5 inches. If the shell is about 1/12 inch thick, find the volume of just the shell, not including the interior of the egg. Round your answer to the nearest tenth.

The volume of the shell will equal the volume of the egg including the shell less the volume of the interior....so we have

(4/3)pi (5 + 1/12)^3  - (4/3)pi(5)^3  =

(4/3)pi  [ (5 + 1/12)^3 - (5)^3 ] ≈ 26.6 in^3

This looks to be the volume of a sphere with a radius of (7.5) 

V=(4/3)3.14*7.5^3 ≈ 1766.25 units^3

tan(67)*14 = 32.981933121536 = x

tan(67*14) = 0.781285626507 = x

Write the answer to whichever one is needed.
