Zoologists are studying two newly discovered species of insects in a previously unexplored section of rain forest. They estimate
salantis [7]
The population Pa of insect A after t years is given by the equation 
     Pa = 1.3(1-0.038)^t 
while the population Pb of insect B after t years is 
     Pb = 2.1(1-0.046)^t

We equate the above expressions to find the number of years t it will take the two populations to be equal: 
     Pa = Pb
     1.3(1-0.038)^t  = 2.1(1-0.046)^t
     1.3(0.962)^t  = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.

We can now solve for t:
     (0.962)^t / (0.954)^t = 2.1/1.3
     (0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
     t = log (2.1/1.3) / log (0.962/0.954)
     t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.

1. What is the perimeter of the figure below. Simplify.<br> 4x^3-5x 2x^3+6x 6x^3+x
____ [38]

Answer:

12x^3+2x

Step-by-step explanation:

The perimeter of a polygon is equal to the sum of its sides.

The sides in the triangle shown have lengths 2x^3+6x, 4x^3-5x, and 6x^3+x in no specific order.

Since its perimeter is given by the sum of its sides, the perimeter is equal to:

2x^3+6x+4x^3-5x+6x^3+x

Combine like terms:

\boxed{12x^3+2x}

LekaFEV [45]

<em>-7 -5 / 4 -2 / -12/2 </em>

<em>-12/2 = -6 </em>

<em>Slope: -6x </em>

<em>5 = 2(-6) + b</em>

<em>5 = -12 + b </em>

<em>-12 + 17 = 5 </em>

<em>Slope intercept Form: y = -6x + 17</em>
