893.42

Step-by-step explanation:

1kg=2.205pounds

so 20mg is for 2.205pounds

therefore for 197pounds will be 1784.84mg

but the dose is once every 12hrs meaning twice a day so divide 1784.84/2 to get the pounds

stiks02 [169]

Answer:

Every decade, the number of species decays by a factor of 0.0834.

Step-by-step explanation:

Let be $S(t) = 25,000,000\cdot 0.78^{t}$ , $\forall t \geq 0$ . The decay rate per decay is deducted from the following relation:

$\frac{S(t+10)}{S(t)} = \frac{25,000,000\cdot 0.78^{t+10}}{25,000,000\cdot 0.78^{t}}$

$\frac{S(t+10)}{S(t)} = 0.78^{t+10-t}$

$\frac{S(t+10)}{S(t)} = 0.78^{10}$

$\frac{S(t+10)}{S(t)} = 0.0834$

Every decade, the number of species decays by a factor of 0.0834.
