16. Alan and Ben each run at a constant rate of 7.5 miles per hour. Carla runs at a constant rate of 10 miles per hour. Debby runs at a constant rate of 12 miles per hour. In a relay race with these four runners as a team running one right after the other, Alan runs 0.3 miles, then Ben runes 0.3 miles, then Carla runs 0.5 miles, then Debby runs 0.24 miles. What is the team's average speed in miles per hour?

the correct answer is 8.93

rewrite using the properties of logarithms using log4, log5, and/or log6

log√5

write logarithmic expression as a single logarithm

[ (2log of b of x / 3) + (3log of b of y / 4)] - 5log of b of z

please help me. thank you!! =]

x = 1/y^2

x = 1/(y+1)^2

x = three over the square root of y

thank you!!! =]

82. let f(x) = 1 - x/2 find f(f(f(x)))

this is read like this: f of x is one minus x over two. find f of f of f of x.

84. let f(x) = 4x - 1 find f(a + h) - f(a) / h

this is read like this: f of x is four x minus one. find f of a plus h minus f of a divded by h

please help me.

I know the last episode aired a long time ago but I still haven't been able to find the song yet. I think it goes something like this "I'm running as fast as I can, holding my heart in my hand" I could be wrong, since it's been so long, but I think thats part of the lyrics.
