(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =
Strike441 [17]

Answer:

  • See below

Step-by-step explanation:

<u>According to the model, the equation is:</u>

  • P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

<u>If b = 1.75, daily growth rate is:</u>

  • 1.75 - 1 = 0.75 = 75%

<u>If  we get P(4) = 55200, find the value of b:</u>

  • 55200 = 3450*b⁴
  • b⁴ = 55200/3450
  • b⁴ = 16
  • b⁴ = 2⁴
  • b = 2

What are the solutions of 6x2 + 2x – 20 = 0? x = x =
Darina [25.2K]

6x² + 2x - 20 = 0

3(2x² + x - 10) = 0

3[(2x² - 4x + 5x - 10)] = 0

3[2x(x - 2) + 5(x - 2)] = 0

3(2x + 5)(x - 2) = 0

3=0, 2x + 5 = 0, x - 2 = 0 (Note: 3=0 is false so disregard that equation)

x = \frac{-5}{2} , x = 2

Answer: x = {\frac{-5}{2}, 2}
