i dun all those hws, iv had enuff of these big idea

find when f(x)= pie/3

you take the evaluated equation and you lose all similar sines by xsing. onse you are left with a group of different signs you square all them and then do the problem. once you have the answer you take the square root of that and then times it by 2^ drwls...

1L = 1000 mL (1.5L to mL) 1mL = 1 cm cube so convert 1.5L to mL and then to cm cube

thank you but how is 171 moles/L equals to 250 mL of the 3.000 M solutions of Ba(OH)2

i think it is so due to the fact that the clean water from the municipal supply has under go purification process just as the bottle water.

the acceleration is decreasing as you increase the mass while keeping the Force constant.... a=F/M

multipy the 6(2-8n)= -36 collect like terms and then solve for n

Potassium is group 2 metal and Bromide nonmetal.....group 7

according to the equation, the acceleration increase as mass decreases......

No I don't think I posted this question :(

What is the magnitude of the torque about his shoulder if he holds his arm straight, but 43.8° below horizontal? I tried multiplying the torque force by sin43.8 but it was wrong :(

sorry wrong post!!!

Bones contain more ________ than any other organ. A. Calcium B. Vitamin C C. Phosphate D. Iron

which regions were favored as areas of human settlement, given the technology available during the classical period?

It is D. They will have no intersection. :)

no, you have to plug in the values for x to get values for y. For instance, if you want x is 2, then y would have to be y=2(2)+.05 which is 4.05. If you want x as 1, y=2.05. Does that make sense Island G?

the villi are just small projections (similar to cilia but not completely) that project from the epithelial lining of the intestinal wall. they are for increasing the surface area of the cell for increased absorption of nutrients. :)

to get y values you have to put the x values into the y equation. Y is a function of x. So for x=1,y=2.05. x=2, y=4.05. x=3, y=6.05. x=4,y=8.05. x=5,y=10.05. x=6,y=12.05. Does that clear things up?

you're welcome!!

what is the solubility of benzophenone in toluene?

0.5 x 0.0019 x sqr(587) x 0.398 x 26.72 = 3,481.12 3481.12 x 587 = 2,043,419.03 2,043,419.03 / 550 = 3715 you're welcome!

F(drag) = 0.5 x 0.0019 x sqr(587) x 0.398 x 26.72 = 3481 P = 3481.12 x 587 = 2043419 Hp = 2043419 / 550 = 3715
