Answer:

5.94x10^1

Step-by-step explanation:

In scientific notation all numbers are written in the form of m×10n (m times ten raised to the power of n), where the exponent n is an integer, and the coefficient m is any real number, called the significand or mantissa. If the number is negative then a minus sign precedes m (as in ordinary decimal notation).

The National Science Organization is monitoring the continuous exponential decline of an insect species due to deforestation. Th

kakasveta [241]

Answer:

$P\geq 26e^{-0.079t}$

$P\geq 2$

Step-by-step explanation:

We are given that there is an exponential decay.

Also, the decrease is of constant rate 7.9% i.e. 0.079 each year.

Since, the initial amount of the species is atleast 26 million.

Thus, the inequality for the corresponding model will be, $P\geq 26e^{-0.079t}$ ,

where t is the time period for the decay and P is the population.

Moreover, is is given that the population cannot be less than 2 million.

So, we get, $P\geq 2$ .

Hence, the inequalities to determine the possible number of insects over time are given by,

$P\geq 26e^{-0.079t}$

$P\geq 2$ .
