i apologize i think may be a very stupid question since simple substitution should most likely work but if it doesn't please inform me what i am doing wrong! Thank you again.

Multivariable Limits! Lim (x^2+y^2)/(1+y^2) (x,y)--> (0,0) evaluate the limit or determine that it does not exist. Im pretty sure that the limit does not exist because if i take it from the y and x axises the values don't match up but not really sure if that is the right way to do it. Any...

Consider the space curve x = cos t, y = sin t, z = sin^2 t. (1) Without plotting this curve, show that this curve lies on the cylinder x^2 + y^2 = 1. (2) Plot this curve (without the cylinder), then use the appropriate rotations to see the planar projections on the xy-plane, the xz-plane and...

Find parametric equations for the line through Po=(3,-1,1) perpendicular to the plane 3x+5y-7z=29. Hey guys I am slightly confused on where to even start on this one the only way i can think about doing it would be finding two other coordinates on the and then taking the cross product of...

monochlorination of methylcyclopentane problem! help Draw all the monochlorinated derivatives of methylcyclopentane that are skeletal isomers of one another. To make a monochlorinated derivative of a compound, replace one H atom in the compound with Cl. This makes me want to cry inside a...

Question given. Predict how the average life span of a nerve cell located in the brain differs from the average life span of a red blood cell. Provide a basis based on cellular features. I know that the average life span of a nerve cell is the life span of the organism which it lives in. The...

can someone give me a fomula to determine the significant difference of the difference in cells/mL in the sample our graph shows 1.7×〖10〗^5 and 1.49×〖10〗^6 how do i find if these numbers are significantly different? I know this is very broad and really doesn't give you much to work with but...

we have done ICE tables but for this reaction none of the initials are given how would I find them with the given information?

For the equilibrium shown below, Kp = 0.20 at 298K PCl5(g) <--> PCl (g) + Cl2 (g) A certain amount of PCl5 is added to a 1.0-L flask. When equilibrium is reached, the total pressure in the flask is 3.00atm. What is the initial pressure of PCl5 in the flask? If someone could point me in the...
