Answer:

The car is $5,499.38 in three decades.

Step-by-step explanation:

Cars lose value over time. Every decade, their value decreases by 1/2. A car is bought for $43,995. How much is it worth in 3 decades? Round to the nearest cent!

First Decade: $43,995 * 1/2 = $21,997.50

Second Decade: $21,997.50 * 1/2 = $10,998.75

Third Decade: $10,998.75 * 1/2 = $5,499.375 ≈ $5,499.38

sasho [114]

Answer: 0.87400mg of caffeine.

Step-by-step explanation:

You have

N(t)=N0(e^−rt)(1)

as a general Exponential decay equation where N0 is the amount at t=0, N(t) is the amount remaining at time t and r is the exponential decay constant. You're specifically given that after 10 hours, the decay factor is 0.2601, i.e.,

N(10)/N(0)=N0(e^−10r)/N0(e^0)= e^−10r=0.2601 . .(2)

Taking the last 2 parts of (2) to the power of 0.1t gives

e^−rt=0.2601^.1t . .(3)

This means that

N(t)=N0(e^−rt)=N0(0.2601^.1t). .(4)

Also,

N(2.56)N(1.56)=N0(0.2601.1(2.56))N0(0.2601.1(1.56))=0.2601.1(2.56−1.56)=0.2601^.1

= 0.87400mg of caffeine.
