If x+9/x=(-3) then find x²-27​
Sedaia [141]

Answer:

x = -9/4

Step-by-step explanation:

We have:

(x + 9)/x = -3

(x + 9) = -3x

3x + x + 9 = 0

4x + 9 = 0

4x = -9

x = -9/4

A boat is heading towards a lighthouse, whose beacon-light is 108 feet above the water. From point AA, the boat’s crew measures
nikklg [1K]

Using the slope concept, it is found that the distance from point A to point B is of 392 feet.

<h3>What is a slope?</h3>
  • The slope is given by the <u>vertical change divided by the horizontal change</u>.
  • It's also the tangent of the angle of depression.

At point A:

  • The vertical change is of 108.
  • The horizontal change is the position x_A, that we want to find.
  • The angle is of 8º.

Hence:

\tan{8^\circ} = \frac{108}{x_A}

x_A = \frac{108}{\tan{8^\circ}}

x_A = 768.6

At point B:

  • The vertical change is of 108.
  • The horizontal change is the position x_B, that we want to find.
  • The angle is of 16º.

Hence:

\tan{16^\circ} = \frac{108}{x_B}

x_B = \frac{108}{\tan{16^\circ}}

x_B = 376.6

Then, the distance is:

d = x_A - x_B = 768.6 - 376.6 = 392

The distance from point A to point B is of 392 feet.
