Answer:

the fourth option

9, 30, 93, 282, 849

Step-by-step explanation:

a1 = 9

based on the sequence definition

a2 = 3×a1 + 3 = 3×9 + 3 = 27 + 3 = 30

the only answer option with a2=30 is the fourth one. all others must be therefore wrong.

check

a3 = 3×a2 + 3 = 3×30 + 3 = 93

a4 = 3×a3 + 3 = 3×93 + 3 = 282

a5 = 3×a4 + 3 = 3×282 + 3 = 849

confirmed.

P(x) =2x3 -11x2 -4x +1 g(x) =2x +1

icang [17]

Answer:

see explanation

Step-by-step explanation:

If (2x + 1) is a factor then x = - $\frac{1}{2}$ is a root and P(- $\frac{1}{2}$ ) = 0 ← Factor theorem

P(- $\frac{1}{2}$ )

= 2(- $\frac{1}{2}$ )³ - 11(- $\frac{1}{2}$ )² - 4(- $\frac{1}{2}$ ) + 1

= - $\frac{1}{4}$ - $\frac{11}{4}$ + 2 + 1

= - $\frac{12}{4}$ + 3

= - 3 + 3

= 0

Since P(- $\frac{1}{2}$ ) = 0 then g(x) is a factor of P(x)
