A 11 gram sample of a substance that’s used to treat thyroid disorders has a k- value of 0.125
NikAS [45]

The substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125

<h3>What is exponential decay?</h3>

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have an exponential function:

\rm N = N_oe^{-kt}

Plug N = N⁰/2

\rm N_o/2 = N_oe^{-kt}

\rm \dfrac{1}{2} = e^{-0.125t}

Solving for t:

t = 5.54 ≈ 5.5 days

Thus, the substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125

Grace is standing 14 feet from a lighthouse and Kelly is standing 12 feet from Grace. The angle that Grace looks up to see the t
mezya [45]
To find the height of the lighthouse, use tan45= \frac{h}{14} to get that h = 14 (the tangent of 45 is 1).  Now for the next question, you have to use the height you just solved for to find angle y.  Use tan(y)= \frac{14}{26} and the inverse tangent button on your calculator tells us that the angle is 28.3. Now for the last question, use the supplement of 45 to get that the angle adjacent to y is 135.  180 - 135 - 28.3 = 16.7  That's your x value.
