You find a fossil, and through careful study you find that only one-sixteenth of the carbon-14 that it once contained is still r

emaining in it. Carbon-14 has a half-life of approximately 5700 years. You can conclude that the age of the fossil is about __________.a. 4 × 5700 yr = 22,800 years
b. 16 × 5700 yr = 91,200 years
c. 1/16 × 5700 yr = 356 years

Answer:

The correct answer is:

5×5700 yr = 28,500 years (d)

Explanation:

The half life of an element/atom is the time is takes for that element/atom to decay to half of its original mass/size.

It was found that the carbon-14 atom had decayed until only \frac{1}{16th} of the original size is still remaining.

Now, let us first find how many half lives are in one-sixteenth, and that is \frac{1}{2}* \frac{1}{2}* \frac{1}{2}* \frac{1}{2} = \frac{1}{16}. so it means that there are 4 half lives in one-sixteenth, and since one half life takes approximately 5700 years, therefore 4 half lives will take 4×5700 yr = 22, 800 years, but at this point (22,800 years ago)the fossil has already half-life, therefore the additional age is to add the number of years it took to decay that half life. hence the age of fossil is:

22,800 + 5700 = 28, 500 years

A company manufactures and sells x smartphones per week. The weekly price-demand and cost equations are p=500−0.5x and C(x)=20,0
suter [353]

Answer:

a)

revenue = x amount of phones x price

revenue = x(500 - 0.5x)

revenue = 500x - 0.5x²

we find revenue' (derivative):

revenue' = 500 - x

x = 500

the company should sell 500 smartphones to maximize revenue, the selling price = 500 - (0.5 x 500) = $250 per smartphone. Maximum weekly revenue = $250 x 500 = $125,000

b)

profit = revenue - cost

profit = 500x - 0.5x²  - 20,000 - 135x

profit = -0.5x² + 365x - 20,000

we must find profit' (derivative):

profit' = -x + 365

x = 365

In order to maximize profits, you have to sell 365 smartphones per week. Maximum weekly profit = -0.5(365²) + 365(365) - 20,000 = -66,612.50 + 133,225 - 20,000 = $46,612.50.

The smartphone's price = 500 - (0.5 x 365) = $317.50
