Anarel [89]

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.
