Find the equation of the curve which passes through the point (1,1) and is defined by the differential equation yer dy Ee2* Show that the curve also passes through the dx point (2,2) and sketch the curve. 4. If the half life of a radioactive element that is decaying naturally is 500 years, find how many years it will be before the original mass of the element is reduced by 75%. 5. What constant interest rate is required if an initial deposit placed into an account that accrues interest compounded continuously is to double its value in six years? Note: Since interest is compounded continuously, the balance N(t) in the account at any time tis governed by the following differential equation: dN =kN dt
