Please help! 100points! A sequence is defined recursively by the given formulas. Find the first five terms of the sequence.
DiKsa [7]

Answer:

<u>5, 18, 44, 96, 200</u>

Step-by-step explanation:

<u>Given</u>

  • aₙ = 2(aₙ₋₁ + 4)
  • a₁ = 5

<u>First term</u> : 5

<u>Second term</u> : a₂ = 2(a₁ + 4)

  • a₂ = 2(5 + 4) = 2(9) = 18

<u>Third term</u> : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44

<u>Fourth term</u> : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96

<u>Fifth term</u> : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200

Hence, the first 5 terms of the sequence are :

  • <u>5, 18, 44, 96, 200</u>

The temperature in a commercial freezer over four days are -2.36 F, 1.68F, -1.81F, and 0.67F what is the mean temperature of the
Nikitich [7]

Answer: -0.455F

Step-by-step explanation:

The mean temperature of the freezer over the four days will be gotten by adding the total temperature and then dividing by 4. This will be:

= (-2.36 + 1.68F + -1.81F + 0.67F) / 4

= -1.82F/4

= -0.455F

The mean temperature is -0.455F

Express the solution of, x^3 + 2x^2 &lt; x + 2, using interval notation?
kati45 [8]
X³ + 2x² - x - 2 < 0

x³ - x + 2x² - 2 < 0

x(x² - 1) - 2(x² - 1) < 0

(x - 2)(x² - 1) < 0

(x - 2)(x - 1)(x + 1) < 0

by chacking we get the solution

x ∈ (-∞,-1) ∪ (-1,1)
