Situation: A 9 gram sample of a substance that's
used for drug research has a k-value of
0.1453.

N = Noekt

No = initial mass (at time t = 0)

N = mass at time t

k = a positive constant that depends on
the substance itself and on the units
used to measure time

t = time, in days

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.
