math 6.1-6.4

Question 1

compound interest formula

Answer 1

a=p(1+r/n)^(n*t)

Question 2

natural base exponential function

Answer 2

e^x

Question 3

continuously compounded interest

Answer 3

a=pe^(rt)
p=principal (starting rate)
r=annual interest rate (decimal)
t=time in years

Question 4

logarithm form

Answer 4

log base b y=x, for example log 2(8)=3

Question 5

exponential form

Answer 5

b^x=y, 2^3=8

Question 6

e^(ln(a))=?

Answer 6

a

Question 7

exponential form and log

Answer 7

e^a=b, log base e (b)=a OR e^a=b, and ln(b)=a
