Two Algebra Questions

 

1) A bank features a savings account that has an annual percentage rate of r=4.6r=4.6% with interest compounded quarterly. Dalton deposits $10,500 into the account.

The account balance can be modeled by the exponential formula S(t)= P(1 + r/n)^nt

where S is the future value, P is the present value, r is the annual percentage rate written as a decimal, n is the number of times each year that the interest is compounded, and t is the time in years.

(A) What values should be used for P, r, and n?

P = _____, r = ______, n = ______

(B) How much money will Dalton have in the account in 1010 years?
Answer = $ ______
Round answer to the nearest penny.

 

2) The number of bacteria in a culture is given by the function
n(t)=935e^0.2t
where t is measured in hours.


(a) What is the exponential rate of growth of this bacterium population?

(b) What is the initial population of the culture (at t=0)?

(d) How many bacteria will the culture contain at time t=6?
