The data below has been taken for the reaction of a dye with the hydroxide ion. The reaction was performed at two different hydroxide ion concentrations while the dye concentration was kept constant. What is the rate law? [OH─] = 0.10 M [OH─] = 0.20 M t (min) Abs l...

never mind! figured it out

range of f(x)= 5^(2x^2-1)^(1/2) i know that the domain of the inverse would be the range of this and i've found the inverse but it has natural logs in it and i don't know how to find the domain with that.. i feel like i'm missing something simple

the pie is 360 degrees divide that by 10 peices it gives you 36 degrees per slice 3 slices left times 36 degrees is 108 degrees

thank youu

i found A and B, just checking if they're right. C i can never remember how to do these. D i haven't tried yet but i could probably figure out but i figured since i was putting the rest up i would do it as well

12, because there is 1 mole of c6h12o6 and 2 moles of o2 so you have a 1:2 ratio

they drew a diagram for it and Q is actually on the left side of the graph making the line L an upward slant, and yes i meant "write"

Line L is tangent to the graph of y= x- (x^2/500) at the point Q a) find the x coordinate of point Q B) right an equation for line L C) suppose the graph above were a hill (measured in feet). There is a 50 foot tree growing vertically at the top of the hill. Does a spot light ...
