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
d. 5 × 5700 yr = 28,500 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 potential investor is seeking to invest $500,000 in a venture, which currently has 1,000,000 million shares held by its founde
Sergeu [11.5K]

Answer:

a, 15%

b, 150,000

c, $ 3.30

d, = $3,333,333.33

e, $3,833,333.33

Explanation:

To solve this,

Note that we have been given a similar venture to compare to our venture.

The total shareholder's equity for the other venture (P) = $10,000,000 and the net income (E) = $1,000,000

Hence, Price/Earnings (P/E) for other venture = 10,000,000/1,000,000 = 10.0

Now for our venture, Earnings in the 5th year = $500,000

Assuming that P/E ratio for both the ventures to be equal, P/500,000 = 10.0

hence, total shareholder's value for our venture = $5,000,000 --------------- (1)

Now the investor invested $500,000 and expected 50% return after 5 years, hence the investor's value after 5 years would be equal to 500,000 * (1+50%) = $750,000 --------------- (2)

Now percent ownership of venture given to investor = (Value of investor's investment after 5 years/total value of all shareholders after 5 years)

Hence, divide (2) by (1)

percent ownership of venture given to investor = 750,000/5,000,000 = 0.15

or 15%

Therefore Answer to part 'a' is = 15%

Part (b) :For the percentage ownership given to new investor = 15%, total number of shares = 1,000,000

Hence, number of shares issued to new investor = 15% x 1,000,000 = 150,000

Hence, answer to part b = 150,000

Part (c): Amount invested by new investor = $500,000 and number of shares issued to him = 150,000

hence issue price of share = Amount invested / Number of shares issued

= 500,000/150,000 = $3.33

Hence, issue price per share = $3.33

Part (d):

The Pre money valuation is the value of the company before any external funding. In this case, the number of shares held with the founders before the new investor = 1,000,000 and the equity price = $3.33

hence, Value of the venture = 3.33 * 1,000,000 = $3,333,333.33

Hence, pre money valuation of the venture = $3,333,333.33

Part (e): Post money valuation of a company is the value of the company after external funding. In this case, investor invests $500,000 to the venture increasing the value of the company by the same amount.

Hence post money valuation = pre money valuation + Investment

= 3,333,333.33 + 500,000

= 3,833,333.33

Hence, post-money valuation of the venture = $3,833,333.33
