Answer:

-8

Explanation:

2x4–5x3+x2+3x+2

Since the value of x=5

By putting the value in the above equation;

= 2(5)4 - 5(5)3 + (5)2 + 3(5) + 2

= 40 - 75 + 10 + 15 + 2

= -8

Therefore if the value of x is 5, the answer of the above equation is -8.

The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many wou
Sergeu [11.5K]

Answer:

50 atoms have decayed during that time

Explanation:

The radioactive decay is represented as

N = N_0 * \frac{1}{2}^X\\

Where N is the amount of radioactive element after a certain time period

N0 is the amount of radioactive element during the initial time period

X is the half life of the radioactive element

Substituting the given  values in above equation,  we get:

N = 100 * \frac{1}{2}^1\\N = 50atoms

So, 50 atoms of carbon-14 remain are left after decaying for 5700 years.

Hence,  atoms of carbon-14 that decay during 5700 years are 100-50 - 50
