Answer: b) -1 < x < 0
<u>Step-by-step explanation:</u>
Graph the equation to see where it crosses the x-axis. The x-intercepts are the zeros of the function.
The graph shows only one zero, which lies between x = -1 and x = 0.
Answer:
10.8109 amu
Step-by-step explanation:
The average atomic mass of boron is determined as the average of the atomic masses of both isotopes weighed by their respective abundances.
Therefore, the average atomic mass is given by:
The average atomic mass of boron isotopes is 10.8109 amu.
The answer would be 77,000
