A student in Greece discovers a pottery bowl

finlep [7]

Answer:

The age of the pottery bowl to the nearest year is 15606 years.

Step-by-step explanation:

Let the initial amount of C-14 in the bowl i.e. $N_{0} = 100$ and today (say after t years) the amount of C-14 in the bowl i.e. N = 21.

Therefore, from the given equation we can write

$21 = 100 e^{- 0.0001t}$ {Since, k is give to be 0.0001}

⇒ $0.21 = e^{- 0.0001t}$

Now, taking ln on both sides we get

ln 0.21 = - 0.0001t (ln e) {Since, $\ln a^{b} = b \ln a$ }

⇒ - 1.560647 = - 0.0001t {We have ln e = 1}

⇒ t = 15606.47 years ≈ 15606 years

Therefore, the age of the pottery bowl to the nearest year is 15606 years.(Answer)

There are eleven people on a softball team and nine different positions. Work through the questions to determine how many ways a

jek_recluse [69]

Answer:

19958400

1814400

Step-by-step explanation:

* Lets explain how to solve the problem

- Permutation is the act of arranging the members into order

- The number of permutations of n members taken r at a time is

denoted by nPr

- nPr = n!/(n - r)! , where n! means n(n - 1)(n - 2)(n - 3) ......... × 1

* Lets solve the problem

- There are eleven people on a softball team

∴ n = 11

- There are nine different positions

∴ r = 9

∴ The number of ways can be made = 11P9

∵ 11P9 = 11!/(11 - 9)! = 11!/2! = 19958400

* The number of total arrangements of the player is 19958400

- If Amy does not want to play pitcher

∵ They are 11 players

∴ The number of players can be pitch = 11 - 1 = 10

* If Amy does not want to play pitcher, then there are now 10 people

available to pitch

- Assuming the pitcher has already be chosen

∴ There are 10 remaining players

∵ The positions are 9

∴ The remaining positions = 9 - 1 = 8

* There are 8 remaining positions

- Lets find how many ways to arrange the remaining positions

∵ n = 10

∵ r = 8

∴ 10P8 = 10!/(10 - 8)! = 10!/2! = 1814400

* The number of ways to arrange the remaining players is 1814400
