Answer:

1

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 4-2)/(4-2)

   = 2/2

   = 1

Situation:A researcher in North America discoversa fossile that contains 65% of its originalamount of C-14..-ktN=NoeNo inital am
zheka24 [161]

SOLUTION

We have been given the equation of the decay as

\begin{gathered} N=N_0e^{-kt} \\ where\text{ } \\ N_0=initial\text{ amount of C-14 at time t} \\ N=amount\text{ of C-14 at time t = 65\% of N}_0=0.65N_0 \\ k=0.0001 \\ t=time\text{ in years = ?} \end{gathered}

So we are looking for the time

Plugging the values into the equation, we have

\begin{gathered} N=N_0e^{-kt} \\ 0.65N_0=N_0e^{-0.0001t} \\ e^{-0.0001t}=\frac{0.65N_0}{N_0} \\ e^{-0.0001t}=0.65 \end{gathered}

Taking Ln of both sides, we have

\begin{gathered} ln(e^{-0.000t})=ln(0.65) \\ -0.0001t=ln(0.65) \\ t=\frac{ln(0.65)}{-0.0001} \\ t=4307.82916 \end{gathered}

Hence the answer is 4308 to the nearest year

What property is illustrated by the statement? 0 + x = x A. Inverse Property of Multiplication B. Commutative Property of Additi
Firlakuza [10]
<h2>Answer:</h2>

Option: D is the correct answer.

The property which is illustrated by the given statement is:

              D. Identity Property of Addition

<h2>Step-by-step explanation:</h2>

We know that an identity is a value which when added to any element of the set gives the resultant as the element itself.

Also, we know that the identity under addition is always: zero.

Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.

Hence, by the Identity Property of Addition we have:

                              0 + x = x
