Solve each equation using the quadratic formula. Find the exact solutions.<br><br> 6n^2 + 4n - 11
Paul [167]

Answer:

\frac{-2\pm\sqrt{70}}{6}}

Step-by-step explanation:

The quadratic formula is \frac{-b\pm\sqrt{b^2-4ac}}{2a}, where a, b, and c are values in the quadratic ax^2 + bx + c. Plug in the values to get \frac{-4\pm\sqrt{4^2-4(6)(-11)}}{2\cdot6} \implies \frac{-4\pm\sqrt{16+264}}{12} \implies \frac{-4\pm2\sqrt{70}}{12} = \boxed{\frac{-2\pm\sqrt{70}}{6}}

A large airplane (plane A) flying at 26,000 feet sights a smaller plane (plane B) travelling at an altitude of 24,000 feet. The
Delicious77 [7]

Answer:

The line of sight distance is 1285.58 feet.

Step-by-step explanation:

The situation is illustrated in the figure attached.

From the figure we see that the altitude difference of the planes and the distance between them form a right triangle with one angle of 40° .

The line of sight between the two planes is the hypotenuse of the triangle.

The altitude difference of the planes is

26,000ft -24,000ft = 2000 ft.

Therefore, if we call x the line of sight distance, from trigonometry we have

$ sin (40^0) = \frac{2000ft}{x} $

\boxed{ x = 1285.58ft}

Therefore, the line of sight distance (x) is 1285.58 feet.
