A boat is heading towards a lighthouse, whose beacon-light is 126 feet above the water. From point AA, the boat’s crew measures
vredina [299]

Using the slope concept, it is found that the distance from point A to point B is of 887 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.

In this problem, the vertical change is of 126 feet.

At point A, the angle is of 6º, while the horizontal position is of x_A, hence:

\tan{6^\circ} = \frac{126}{x_A}

x_A = \frac{126}{\tan{6^\circ}}

x_A = 1198.8

At point B, the angle is of 22º, while the horizontal position is of x_B, hence:

\tan{22^\circ} = \frac{126}{x_B}

x_B = \frac{126}{\tan{22^\circ}}

x_B = 311.9

Hence, the distance in feet is of:

d = x_A - x_B = 1198.8 - 311.9 \approx 887

Tolong bantu jawab please, makasih sebelumnya!
sweet [91]

Answer:

2x² - 3x - 2

Explain:

Use the FOIL method: (a +b)(c +d) = ac + ad +bc +bd.

2x² + x - 4x - 2

Collect like terms.

2x² + (x - 4x) - 2

Simplify.

2x² - 3x - 2
