Using an exponential function, it is found that the multiplier used to predict the amount of medication remaining 2 hours after the peak level is of 0.6889.
<h3>What is an exponential function?</h3>A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that the decay rate is of r = 0.17, hence:
After 2 hours, the multiplier is given by:

Answer:
∴ ∠BAD = (0.2044) = 11.8°
Step-by-step explanation:
i) AD = 9 cm
ii) DC = 3 cm
iii) ∠BCD = 35°
iv) Since AB is parallel to DC and ∠ABD = 90° then we can conclude that ∠BDC = 90°.
v) = 0.6128 ∴ BD = 3
0.6128 = 1.84 cm
vi) ∴ sin(∠ BAD ) = ⇒ sin(∠ BAD ) =
= 0.2044
∴ ∠BAD = (0.2044) = 11.8°
