Answer:

Step-by-step explanation:

1) x + 1 = 0

x = -1

P(x) = x³ + 5x² + 2x + 1

P(-1) = (-1)³ + 5(-1)² + 2*(-1) + 1

       = -1 + 5*1  -2 +1

       = - 1 +5 - 2 +1

P(-1) = 3

2)x -5 =0

x = 5

P(x) = x³ - 6x² + 5x + 2

P(5) =5³ -6*(5)²  + 5*5 + 2

    = 125 - 6*25 + 25 + 2

   = 125 - 150 + 25 +2

  P(5) = 2

Which statement is true about the flight of 2 rockets?
umka21 [38]

Answer:

  The first rocket, g(x), reached its maximum height before the second rocket, h(x).

Step-by-step explanation:

Each equation is in vertex form, so we can read the vertex of the rocket's path from the equation.

  y = a(x -h)^2 +k . . . . . . has vertex (h, k)

__

g(x) has vertex (time, max height) = (4, 170).

h(x) has vertex (time, max height) = (5, 170).

The rockets have the same maximum height (170), but the first rocket, g(x), reaches that height in 4 seconds, one second sooner than the second rocket, h(x).

The first rocket, g(x), reached its maximum height before the second rocket, h(x).
