Question

The worldwide sales of flash memory chip (in billions of dollars) is approximated by

The worldwide sales of flash memory chip (in billions of dollars) is approximated by S(t) = 4.3(t + 2)0.94 (0 ? t ? 6) where t is measured in years, with t = 0 corresponding to 2002. Flash chips are used in cell phones digital cameras, and other products. What were the worldwide flash memory chip sales in 2002? (Round your answer to two decimal places.) What were the estimated sales for 2003? (Round your answer to two decimal places.)

Explanation / Answer

The given S(t) function is the worldwide sales of flash memory chips in billions of dollars


t = 0 is the year 2002 so
(a) S(0) = 4.3(0 + 2)^(.94) = 8.25 billion


(b) t = years since 2002 so 2003 would be t = 1:

S(1) = 4.3(1 + 2)^(.94) = 12.08 billion
