your answer would be 17/25
This is the distributive property of multiplication. The -2 was distributed into the parentheses.
Let 1993 = time 0 = 0.
Let 1999 = time 6 = 6
Let 2012 = time 19 = 19
So, a = 171 (million). First solve for k.
176 = 171 e^k6
176/171 = e^(k*6)
ln (176/171) = 6k
k = 1/6 ln (176/171)
So, in 2012 we have: P(19) = 171 e^(19k), where k = 1/6 ln (176/171)
Hope this helped!
To solve this problem, you should know what is the not recovered waste for each item. To solve this, you should deduct the waste recovered from waste generated.
So for paper, the waste that is not recovered is 2.674 x 10^7.
While for glass, the not recovered waste is 0.840 x 10^7.
Lastly for plastics, the waste that is not recovered is 3.0554 x 10^7.
So by adding these three items, we can get now the total waste not recovered.
2.674 x 10^7 + 0.840 x 10^7 + 3.0554 x 10^7 = 6.5694 x 10^7.
