20.) 8y=300- So take the log of both sides,
log 300 = log 8y
Writing 300 as 3*100,
log(3*100)=log 8y
Using log(AB) = log A+log B,
log 3+log100=log 8+log y
Because log 100=2,
log 3+2=log 8+log y
Rearrange: log 8-log 3=log y-2
By log(A/B)=log

What this means is that you are going to do 1/5(2.9+3.6+4.5+4.9+5.5) The 5 above the symbol means
how many numbers you are going to have within the () since you need the average you multify by 1/5 (or

114.) A) 2007 is 5 years after 2002, so x = 5. Just plug this into the function:
f(5) = 8 + 38 ln(5) = 69.12
Hence it overes

Therefore it is the vector
i
The magnitude of the green vertical vector is
Therefore it is the vector
