y = c ekxpassing through (1, 180) and (3, 20).(Note: All of the 'log' in the following are natural logs.)log(y) = log(c) + k log(x)Log(180) = log(c) + k log(1) = log(c)c = 180log(20) = log(180) + k log(3)log(20) - log(180) = k log(3)k = log(20/180) / log(3) = - log(9) / log(3) = -2y = 180 e-2xIn checking my work, I find that this doesn't work at all.Oh woe! Where have I failed ?--------------------------------------------Here's what I did:y=Cekx which passes through the points (1,180) & (3,20)(1) Substitute the values of x & y to create two equations:180 = Cek & 20 = Ce3k(2) Rearrange in terms of the constant, C:C=180/ek & C=20/e3k(3) Since both sets of points satisfy the exponential function, the constant will be the same so:180/ek = 20/e3k(4) Now rearrange and solve for k:180e3k = 20ek9 = e(k-3k)ln(9) = ln(e-2k)ln(9) = -2kk = -ln(9)/2 which is approx. -1.09861(5) Now substitute k into one of the equations to solve for C:C =180/e(-1.09861)C = 539.9987 or rounded to 540So the exponential function that includeds the points (1,180) & (3,20) can be approximated as:y = 540ekx , where k = -1.09861
log(2) + log(4) = log(2x)log(2 times 4) = log(2x)2 times 4 = 2 times 'x'x = 4
how do i log in
log(36,200) = 4.558709 (rounded)log[log(36,200)] = 0.658842 (rounded)
False When logs are taken, division becomes subtraction, so the log of a quotient is the log of the numerator minus the log of the denominator.
Log In Everyday
No, but you will get points on your CSA2010 report.
Points for the team, points against the team, points difference, tries for the team, tries against the team and bonus points
Points against your license, no. But it does put points... and a pretty substantial number of them, at that... on your CSA report.
Yes. It was a purple-painted log with points at the ends.
by playng games in nick and make sure your log in
50
well go to the website log in and then go buy igg points.buy how many you want.then go to the igg exchange and trade igg points for wlo points
Sort of. If you log your exercise you can trade some of that for extra points to eat.
You Get Wireless internet make and Nintendo club and log on to it and shop with your 1000 points
Every thirty days you log on to Howrse you get 1 karma point.
