2x² + 4x + 4 + x² + 1 = 180

Tasya [4]

Step-by-step explanation:

$2 {x}^{2} + 4x + 4 + {x}^{2} + 1 = 180$

$3 {x}^{2} + 4x + 5 = 180$

${3x}^{2} + 25x - 21x - 175 = 0$

$x \times (3x + 25) - 7(3x + 25) = 0$

$(3x + 25) \times (x - 7) = 0$

$3x + 25 = 0 = x - 7 = 0$

$x = - \frac{25}{3} = x = 7$

$= x_{1} = - \frac{25}{3} . \: \: x_{2} = 7$

A sequence is defined recursively using the formula f(n + 1) = -0.5f(n). If the first term of the sequence is 120, what is f(5)?

PolarNik [594]

Answer: 7.5

Step-by-step explanation:

The given formula tells us that the next term f(n+1) of the sequence is -0.5 times the previous term f(n)

First term of the sequence is f(1) = 120

Second term of the sequence is f(2) = f(1+1) = -0.5 f(1) = -0.5 (120) = -60

Third term of the sequence is f(3) = f(2+1) = -0.5 f(2) = -0.5 (-60) = 30

Fourth term of the sequence is f(4) = f(3+1) = -0.5 f(3) = -0.5 (30) = -15

Fifth term of the sequence is f(5) = f(4+1) = -0.5 f(4) = -0.5 (-15) = <em>7.5</em>
