Answer:

  • team: 8 kph
  • current: 4 kph

Step-by-step explanation:

The downstream speed is ...

  speed = distance / time

  speed = 36 km/(3 h) = 12 km/h

The upstream speed is ...

  12 km/(3 h) = 4 km/h

__

If b and c represent the speeds of the boat and current, respectively, then we have ...

  b + c = 12

  b - c = 4

Adding these gives ...

  2b = 16

  b = 8

  c = b -4 = 4

The rate of the rowing team in calm water is 8 km/h; the rate of the current is 4 km/h.

The x-coordinate of the vertex of the equation y = 2x2 − 4x + 12 The x-coordinate of the vertex of the equation y = 4x2 + 8x + 3
dolphi86 [110]

So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is x=\frac{-b}{2a}, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:

y = 2x^2 − 4x + 12: x=\frac{4}{2*2}=\frac{4}{4}=1

y = 4x^2 + 8x + 3: x=\frac{-8}{2*4}=\frac{-8}{8}=-1

In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
