Answer:

Answer: B

<u>Explanation:</u>

           rate    x    time

Chris:   40     x       t      = 40t

Amy:    60     x     t - 2   = 60(t - 2)

Use the distance formula:

d = \sqrt{(Chris)^{2}+(Amy)^{2}}

300 = \sqrt{(40t)^{2}+(60(t - 2))^{2}}

*****************************************************************************

Answer: B

<u>Explanation:</u>

  x² - 8x + 19

a=1  b=-8  c=19

Use the Quadratic formula to find the solutions for x:

x = \frac{-b +/- \sqrt{b^{2}-4ac}}{2a}

  = \frac{-(-8) +/- \sqrt{(-8)^{2}-4(1)(19)}}{2(1)}

  = \frac{8+/- \sqrt{64-76}}{2}

  = \frac{8+/- \sqrt{-12}}{2}

  = \frac{8+/- 2i\sqrt{3}}{2}

  = \frac{2(4+/- i\sqrt{3})}{2}

     = 4 ± i√3

Solutions are:                  Factors are:

x = 4 + i√3                       x - (4 + i√3) = 0

x = 4 - i√3                       x - (4 - i√3) = 0

Which geographic factors present problems for the middle east?.
Grace [21]
Rivers allowing for productive agriculture were the key factor in the settling of cities. Mountain ranges kept cultures in separate areas, providing natural barriers to imperialist agendas. The rich, fertile soil of the Middle East led early civilizations to settle, domesticate plants and animals, and thrive.
