On the basis of data collected during an experiment, a biologist found that the growth of a fruit fly population (Drosophila) wi
Ket [755]

Answer:

(a). 15

(b). 78

Step-by-step explanation:

Growth of the population of a fruit fly is modeled by

N(t) = \frac{600}{1+39e^{-0.16t} }

where t = number of days from the beginning of the experiment.

(a). For t = 0 [Initial population]

N(0) = \frac{600}{1+39e^{-0.16\times 0} }

       = \frac{600}{1+39}

       = \frac{600}{40}

       = 15

Initial population of the fruit flies were 15.

(b).Population of the fruit fly colony on 11th day.

N(11) = \frac{600}{1+39e^{-0.16\times 11} }

       = \frac{600}{1+39e^{-1.76} }

       = \frac{600}{1+39\times 0.172 }

       = \frac{600}{1+6.71}

       = \frac{600}{7.71}

       = 77.82

       ≈ 78

On 11th day number of fruit flies colony were 78.

Help please! Need to finish this assignment! Have more like this if someone could please help!
Alchen [17]

Answer:

\bar{AD}\parallel \bar{BC}

Step-by-step explanation:

If m\angle 4=m\angle8, then m\angle4 and m\angle4 are alternate interior angles.

This means that line segment AC is a transversal.

This implies that line segment AD is parallel to line segment BC.

The second choice is the correct answer.

Fantom [35]

Answer:

$3,800

Step-by-step explanation:

$200 (down payment) + 48 x $75 (monthly payments)


$200 + $3600 = $3800


Since the original car was $3450, there was $350 in interest ($3800 - $3450 = $350)
