How old is a skeleton that has lost 27% of its carbon-14? Use the exponential decay model for carbon-14, A=A0e^-0.000121t Round the answer to the nearest whole number

2,601 years

Step-by-step explanation:

Given the decay model for carbon-14

We want to determine the age of a skeleton that has lost 27% of its C-14.

Initial Value of C-14=100%=1

Present Amount, A(t)=100%-27%=73%=0.73

Substituting these into the model, we have:

The skeleton is approximately 2,601 years old.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
