A student in Greece discovers a pottery bowl

Mathematics
1 answer:
finlep [7]3 years ago
3 0

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)

Name a number that has the same absolute value as 23
IRINA_888 [86]

Answer: A number with the same absolute value of 23 is -23.

Explanation: The absolute value of a number is how far it is from zero, and the absolute value of a number is always positive, unless the number is 0, in which case the absolute value is neutral, and the absolute value is 0.

Examples: 6 is 6 away from zero, so the absolute value of 6 is 6.

−6 is 6 away from zero, so the absolute value of −6 is 6.

Given: F(x) = 2x + 3, find F(X+h)-f(x) and simplify.<br> 01<br> 02<br> (2h+6)/h
antiseptic1488 [7]
F(x+h) = 2(x+h) +3= 2x + 2h +3
f(x) = 2x + 5

f(x+h) - f(x) = 2x + 2h + 3- 2x - 3= 2h

[f(x+h) - f(x)]/h = 2h/h = 2
