Suppose that a sum S0 is invested at an annual rate of return r compounded continuously. a. Find the time T required for the original sum to double in value as a function of r. b. Determine T if r = 7%. c. Find the return rate that must be achieved if the initial investment is to double in 8 years.

Answer

given,

Sum = S₀

annual rate of return = r

T is the time

Ordinary differential equations is

integrating both side

e^C = S₀

a) time when sum is doubled

b) Time T if r = 7 %

        T = 9.9 years.

c) return rate, r = ? T = 8 years

         r = 0.0866

        r = 8.67%

step-by-step explanation:

10 - 2.8 = 7.2

2 2/5 = 2.4

7.2 / 2.4 = 3

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
