The weights of Sarus crane chicks and hooded crane chicks H (both in grams) during the 10 days following hatching can be modeled

by the functions S = –0.122t3 + 3.49t2 – 14.6t + 136 H = –0.115t3 + 3.71t2 – 20.6t + 124 where t is the number of days after hatching. According to the models, what is the difference in weight between 5-day-old Sarus crane chicks and hooded crane chicks? Round your answer to the nearest thousandth, if necessary.

Answer:

  • 35.875 grams

Step-by-step explanation:

Given

<u>Functions:</u>

  • S(t) = –0.122t³ + 3.49t² – 14.6t + 136
  • H(t) = –0.115t³ + 3.71t² – 20.6t + 124  

<u>Finding the difference between S(5) and H(5)</u>

  • S(5) - H(5) =
  • –0.122t³ + 3.49t² – 14.6t + 136  - (–0.115t³ + 3.71t² – 20.6t + 124) =
  • (-0.122 + 0.115)*5³ + (3.49 -3.7)*5² - (14.6 -20.6)*5 + 136 - 124 = 35.875

Answer is 35.875 grams
