Assume the amount of pollution entering the world's oceans grows exponentially. At the start of 1900 suppose that the instantaneous rate at which pollution enters the oceans is 107 tons per year, and that the amount doubles every 10 years thereafter.
Express the rate that pollution enters, in units of tons per year, at a time t years after 1900.
Fill in below an integral which expresses the total amount of pollution which has entered during the period 1900 to 1990. int_a^b dt
