Answer:
c = 8.14 million×(0.9166)^t
4.83 million
Step-by-step explanation:
Data:
t = y - 2007
c₀ = 8.14 million
c₃ = 23 % less than c₁
Part 1. Calculate c₃
c₃ = c₀(1 - 0.23) = 0.77c₀
Part 2. Calculate r
c₃ = c₀r^t
0.77c₀ = c₀r³
0.77 = r³ Divided each side by c₀
r = 0.9166 Took the cube root of each side
The explicit decay model is c = 8.14 million×(0.9166)^t
Part 3. Prediction
t = 2013 - 2007 = 6
c = c₀r^t = 8.14 million×(0.9166)⁶ = 8.14 million × 0.5929 = 4.83 million
The model predicts that there will be 4.83 million cars for sale in 2013.
The answer is 2.34 x 10-11 g
Answer:
14 1/2
Step-by-step explanation:
Rewriting our equation with parts separated
=7 + 7/8 + 6 + 5/8
Solving the whole number parts
7 + 6=13
Solving the fraction parts
7/8 + 5/8= 12/8
Reducing the fraction part, 12/8,
12/8=3/2
Simplifying the fraction part, 3/2,
3/2=1 1/2
Combining the whole and fraction parts
13 + 1 + 12=14 1/2
