Answer:
7pi/6
Step-by-step explanation:
Using the formula for arc length in radians, we get:
- 14pi = 12(theta)
- theta = 7pi/6 [divide both sides by 12]
The minimum cost is achieved when 150 trees are produced giving a minimum cost of $27.5
Polynomial is an expression that involves the <em>operations of addition, subtraction, multiplication of variables.</em>
Let C represent the cost for buying and caring for n trees. Given that:
C = 0.001n² - 0.3n + 50.
The minimum cost is at dC/dn = 0, hence:
dC/dn = 0.002n - 0.3
0.002n - 0.3 = 0
0.002n = 0.3
n = 150
C(150) = 0.001(150)² - 0.3(150) + 50 = 27.5

Answer:
0.59 cents
Step-by-step explanation:
To find how much he paid for 1 pound, you divide $19.20 by 2 = $9.60
Then you divide $9.60 by 16(ounces) = $0.59 cents (or $.0.60, rounded, but is closest to that answer)
