Pe^rt and A=P(1+r/n)^nt (rate, # it compounds per year, years) Pump fill 4hr., 2nd fill 3hr. t/4+t/3=1 multi. By 3, 4, then 12. Cancel base and solve. Or find CD and #?s to make it. Add #?s and / CD by sum. Set de. = 0. Cancels r holes. Stayed r va?s. degree of nu. Higher- no ha. Lower- it?s y=0, x-axis. =, then it?s at y= LC of nu./LC of de. Y-int= c of nu./c of de. Even + S E, Even ? s e (parabola), odd + s E, odd ? S e (line). Think of self as y-axis. Standard dev. = ox on calc. 68, 95,99.7. 95-68/2=13.5. inside + left, - right; outside + up, - down. When (a) is -, graph flips horizontally. If (a)>1, narrower; vice versa (absolute value). |Variable-Given value| = Difference/Error. When = x (-b/2a), what = y (insert x), when hit ground = quad formula.
