Answer: 35.36
----------------------------
Work Shown:
N(t) = N0*(1/2)^(t/5730)
N(t) = 200*(1/2)^(t/5730)
N(14325) = 200*(1/2)^(14325/5730)
N(14325) = 200*(1/2)^(2.5)
N(14325) = 200*0.17677669529663
N(14325) = 35.355339059326
N(14325) = 3<span>5.36</span>
You were fairly close to the answer
By the <span>tangent-secant theorem:
x</span>² = 5(5+12) = 5 * 17 = 85
x = √85 ≈ 9.2
