f(x) = x³ - 2x² - 24x

x³ - 2x² - 24x = 0

x(x² - 2x - 24) = 0

x = 0

x² - 2x - 24 = 0

a = 1, b = -2, c = -24

Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100

x = (-(-2) - 10)/(2 * 1) = -8/2 = -4

x = (-(-2) + 10)/(2 * 1) = 12/2 = 6

The angle of elevation from a ship to a

GREYUIT [131]

Answer:

Step-by-step explanation:

The angle we are given is 2° and we are given the opposite leg, 135 ft. We are trying to find the hypotenuse length- the diagonal distance from the ship to the lighthouse.

So, we use SOHCAHTOA with sine:

$sin(2)=\frac{opp}{hyp}= \frac{135}{x}$

$x = \frac{135}{sin(2)} = 3868.251 ft$

Keep in mind that the angle is in degrees. Also, the number is large because of the extremely short angle.
