If a 25 foot 1/2 inside diameter pipe was placed vetically, filled with water what would be the PSI? I don't understand the equation below.
What would be the numerical answers to Dw and G
Pressure = P = Dw x G x H
Whereby, P = Pressure in Psi
Dw = Density of Water
G = Gravity in Feet / Second^2
H = Height in feet, distance from A to B whereby
Point A is from the surface of the water
Point B is any point that you wish to calculate but
logically it won't exceed 25 feet.

∫1/(cos² x + sin² x) dx from ∏ to 0 =
∫sec² x/(1+tan² x) dx = arctan (tan x) |∏ to 0 = 0

i know the mistake is with arctan (tan x) |∏ to 0 , but i cannot show why, as
∫f'(x)/(a²+(f(x))² dx = 1/a arctan[(f(x)/a]....can someone enlighten me? thanks

based on market research :

if the sales of a product are high
the company can make a profit of $3.1million/year
if 'so so', make a profit of $1.5million/year
if sales are low then lose $0.5million

the probabilities for the two profit scenarios are 0.65 and 0.14 respectively

calculate the standart deviation of profit for the prodcut in millions to 3 decimal places

too hard to put the standard deviation formular here
my answer is
[0.65-(0.65+0.14)/n]square/n-1=
if the n is =2
then =0.065025
open root =0.255

does it seem right to you?

repects for y'all who check this answer for me.
thx a lot.

from 1987 to 1997 the #'s of banks could be found by this equation, N(t) = -458t + 923,769. where "t" is the year. approx. what is the # of banks in 1987 and 1997?

do i need to find the "t" first? but how do i find that if it only gives me 1987 and 1997? do i need to subtract the years to find "t"?

thanks for the help.

When I was in Middle School I asked why you couldn't divide by zero. I was told the generic answer that ... you just can't. In high school I was told that it is undefined. I was told by an engineer that zero divided by zero was actually infinity. At the time he was trying to explain that the closer and closer you get to zero the higher and higher the number got but I couldn't "get" it then.

Now having taken Calc 1 I understand limits and I guess what he was trying to explain was (and excuse my syntax, as the text only formula is not conductive to mathematical formula writing) The limit as x approaches 0 of 0/X is infinity. Is this what he was getting at by saying that zero / zero is infinity or was he just making a false assumption that since both the right and left side of the function approach infinity that zero / zero was infinity?

I appreciate your help!!!
