for jhanna_12's question: 72 & 49.

for shroudedbylies's qn
The answer is : I = 2/3 + 4/3*e^(-3T/4)
As T tends to infinity, 4/3*e^(-3T/4) tends towards 0
therefore, I = 2/3 amperes (or whatever units it is in).

gradient: 2.5, y-intercept: 5

2x -0.5y = 3
x - y = 2
find x & y
Posted 1/14/10
x = 4/3, y = -2/3

x (x -5) = y
sin x = y

find the intercepts
