A zip line is setup 150ft in the air, where a person can expect to zip line at a safe declining speed to the ground as they pass
hichkok12 [17]

Answer:

139 ft

Step-by-step explanation:

So the zip line forms a right triangle.  The height of the triangle is 150 ft, and the opposite angle is 40°.  The horizontal distance covered by the zip liner can be found with trigonometry, specifically with tangent.

tan 40° = 150 / x

x = 150 / tan 40°

x ≈ 179 feet

But this includes the 40 ft long body of water, so the amount of ground covered is:

179 ft - 40 ft = 139 ft

X^2+2x+9=0 please?!<br>​
Nadusha1986 [10]

Answer:

D

Step-by-step explanation:

Given a quadratic equation in standard form : ax² + bx + c = 0

We can solve for x using the quadratic formula

x² + 2x + 9 = 0 ← is in standard form

with a = 1, b = 2 and c = 9

x = ( - 2 ± \sqrt{2^2-(4(1)(9)}) / 2

  = ( - 2 ± \sqrt{4-36}) / 2

  = (- 2± \sqrt{-32}) / 2)

  = (- 2 ± \sqrt{16(2)(-1)}) / 2

  = ( - 2 ± 4i\sqrt{2}) / 2

  = \frac{-2}{2} ± \frac{4i\sqrt{2} }{2}

  = - 1 ± 2i\sqrt{2} → D
