Answer:=−x3+26x2+−7x+−13+6x4+−x3+8x+27
=(6x4)+(−x3+−x3)+(26x2)+(−7x+8x)+(−13+27)
=6x4+−2x3+26x2+x+14
Answer: =6x4−2x3+26x2+x+14
Answer:
<u>5, 18, 44, 96, 200</u>
Step-by-step explanation:
<u>Given</u>
<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>
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
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)
