Answer:
16,767
Step-by-step explanation:
Geometric sequence formula: an = ar^n-1
Now, we just plug in the values.
an = 23(3)^7-1
an = 23(3)^6
an = 23(729)
an = 16,767
The half life of the radioactive isotope to the nearest tenth is 0.83 days.
<h3>What is rate of radioactive decay?</h3>
The rate of radioactive decay is the rate at which a radioactive isotope is disintegrated. The half life is the time taken for half of the original amount of radioactive isotope to remain.
Given that;
t/12 = 0.693/k
Where;
t1/2 - half life
k =decay constant
t/12 = 0.693/0.84
t/12 = 0.83 days

Answer:
The answer for ∠B = 68°
Step-by-step explanation:
Total angle in a triangle is 180° so you can just substract ∠A and ∠C from 180° :
∠A + ∠B + ∠C = 180°
90° + ∠B + 22° = 180°
∠B = 180° - 90° - 22°
= 68°
