The population of Nevada was 3.0 million in 2018 and 2.7 million in 2010. Assuming an exponential model: (a) Write the population of Nevada in the form N= Noat, where N is the population of Nevada in millions, No and a are constants, and t is time in years since 2010. NOTE: Enter the exact answer for No. Enter an exact value for a or round to 4 decimal places. N (t): - (b) What was the estimated population of Nevada in 1996? NOTE: Round your answer to 3 decimal places. The population in 1996 was approximately million people.
The change to a villages population over time can be represented using an exponential decay function. P(t) = P0ert (t ≥ 0) P(t) represents the village population at time (t), measured in years. Initially at time t=0, there are 12,000 people in the village. After 4 years, only 5,000 people remain. A. Show the value of P0 is 12,000 and hence, state the equation for P(t) B. Show that the value of the constant r is −0.219 to three significant figures.C.
Radioactive elements decrease (or decay) exponentially. Suppose that 124 mg of an unknown radioactive element decays down to 98 mg after 14 days. (a) What is the half-life of the element? That is, how many days will it take before half of the original sample has decayed? half-life: days (rounded to at least 2 decimal places) (b) How long will it take for a sample of mg to decay to 14 mg? time needed: days (rounded to at least 2 decimal places)
