Nathan Cannon · Answer 1

That is alot of qeustions

I will be puting less detail tho

first one

f (3) = 2 (0.75) ^3=0.84375

D

2nd one

declining since it is less than 1, 100-94=6, so declining by 6%

D is answer

3rd one

rememeber that loga-logb=log (a/b)

so, log32-log8=log (32/8) = log4

A is answer

4th one

log25

evaluate using your calculator

1.39794

D
