Help with this exponential function!

butalik [34]

The population size after 6 years and after 8 years are 147 and 169 population respectively

<h3>Exponential functions</h3>

The standard exponential function is expressed as y = ab^x

where

a is the base

x is the exponent

Given the function that represents the population size P (t) of the species as shown;

$p(t)=\frac{550}{1+5e^{-0.1t}} \\$

For the population size after 6 years

$p(t)=\frac{550}{1+5e^{-0.1(6)}} \\P(6)=\frac{550}{3.744}\\ P(6)=147 population$

For the population after 8 years

$p(t)=\frac{550}{1+5e^{-0.1(8)}} \\P(8)=\frac{550}{3.2466}\\ P(8)=169 population$

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

Trey evaluated 12/15 + 1/10 and got the answer of 13/25. which statement is true about this answer?

Ganezh [65]

Answer:

Option C. His answer is not correct, because the same can not be less than either attend

Step-by-step explanation:

we have

$\frac{12}{15}+\frac{1}{10} =\frac{13}{25}$

we know that

$\frac{12}{15}=0.8$

$\frac{1}{10}=0.10$

$\frac{13}{25}=0.52$

substitute

$0.80+0.10=0.52$ ----> is not true

therefore

His answer is not correct, because the same can not be less than either attend
