We were discussing Evolution in our Bio class the other day and the question came up. Since I come from a Catholic school, most of my classmates believe in it while I kinda think its just a bunch of bullshit...a passage in the Bible that might have been taken too literally or something. What is Creationism really? And how valid a theory is it to even be compared with Darwin's Theory on Evolution?

Ok here is the question: Find the equation of the line which is parallel to the line 3x-2y+5=0 and which passes through the point of intersection of the lines 4x+y+3=0 and 5x-2y+8=0

My working:
m=3/2 <--- from 3x-2y+5

(4x+y+3)+k(5x-2y+8)
4x+y+3+5kx-2ky+8k
x(4+5k)+y(1-2k)+(3+8k)
4+5k/2k-1=3/2 <---- gradient of line above
8+10k=6k-3
4k=-11
k=-11/4
(4x+y+3)-11/4(5x-2y+8)
4(4x+y+3)-11(5x-2y+8)
16x+4y+12-55x+22y-88
= -39x+26y-76=0 <------ my answer, however this is wrong and instead it is supposed to be 39x-26y+76=0 according to my textbook.

Where did i go wrong?

What i mean is that almost all first world countries have four seasons. For example, Iran is a first world country but it's not a four seasos. It's only because of the oil they have. What reason can it be??
Most first world countries lie in the capricorn and cancer part of the world almost never in the tropic!
I'm curious! Do you have any references? That'd really help!

Puhleese help me on this one, electronic engineers out there!

Vpk=1V, Vrms = √2 V, Rsourcevoltage = 50Ω (bummer#1) L=56mH, Rinductor = 56Ω(bummer#2), C=100nF, Rload=120Ω

Find: impedance, circulating current (thats Ipk or Irms??? :-S), and VOLTAGES across EACH COMPONENT (megabummer) using theoretical as well as complex analysis.

I know internal resistances can be summed with load as series resistance, but what about the Icirculating (pk or rms???), and VOLTAGE? Do i find voltage across(L+Rinductor) or what?

{lease solve the entire question with steps, if that's not too much to ask. I'm sure there are people who love such questions and are raring to go.

Well? Help!

Quite seriously im taking this que to heart as its a major percent of my finals, the nose bleeds are not stopping. Really.

500 grams of a radioactive substance is expected to decay exponentially to 125 grams in the course of 20 years.


(a) Write down the half-life, and the rate of decay of the radioactive substance.









(b) Write down the function in time, N(t), where t is in years, representing the exponential decay of the radioactive substance.











(c) How much of the substance is expected to remain after 15, 25, and 40 years, respectively?. How long would it take for the radioactive substance to decay to under 1 gram?.

please,
i need your help.
my cousin keeps getting high off this stuff,
coricidin cough and cold for high blood pressure-
it has chlorpheniramine maleate
and
dextromethorphan hydrobromide
he took like 4 of these little pills.
the box says take one,
not more than 4 in 24 hours.
he doesnt have high blood pressure
and hes 18.
what effects does it have,
can he die from it?

i kept a spider in a small glass bottle with a plastic cap (yes i become cruel when my sense of observation heightens XD). i open the bottle around 2-3x a day only to capture small moths around the house for its food. and its still alive and kicking even if i haven't poked holes on the bottle cap. so, do they breathe?
