0.725kg or 725 grams
5.8 kg ÷ 8 star containers = 0.725 kg
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses
1 Year: 19
2 Years: 9.50
3 Years: 4.75
4 Years: 2.38 (2.375, but rounded)
<span>y=2(1/2)^x
</span>
x = 0; <span>y=2(1/2)^0 = 2(1) = 2
x = 1; </span><span>y=2(1/2)^1 = 2(1/2) = 1
answer is the last one.</span>
