Penjelasan dengan langkah-langkah:

Answer 2

1. F(2) = 2500

2500 = 4000 - 1000e^(k.2)

-1500 = -1000.e^(2k)

1,5 = e^(2k)

ln(1,5) = ln(e^(2k))

2k = ln(3/2)

k = 1/2. ln(3/2)

k = ln(√(3/2))

2. F(4) = 4000-1000.e^(4k)

           = 1000.(4-e^(4.ln(√(3/2) ))

           = 1000.(4 - (√(3/2)⁴)

          = 1000(4 - (3/2)²)

         = 1000(4 - 9/4)

         = 1000(16/4 - 9/4)

        = 1000(7/4)

         = 250.7

F(4)    = 1750 laptop
