Ok you need to do y-(-2) over -3-(-9) and you get(y+2)/(-3+9)=1
so y+2=1*6
y+2=6
y=4

The angle of depression from the top of a cruise ship to the top of a sailboat is 22. Sitting above water, the cruise ship is 23

dusya [7]

Answer:

The distance between the cruise ship and the sail boat is 517 feet.

Step-by-step explanation:

The cruise ship is 236 feet tall, and the sailboat is 236 tall; this means the distance between the top of the cruise ship and the top of the sail boat is

236 feet - 27 feet = 209 feet.

We also know that the angel of depression from the top of the cruise ship to the bottom of the cruise ship is 22°. This forms a right triangle as shown in the figure attached.

Now from trigonometry we get:

$tan \: \theta = \dfrac{209}{d}$

$d= \dfrac{209}{tan\:\theta }$

$\boxed{d=517ft}$

The distance between the cruise ship and the sailboat is 517 feet.

Can someone solve this for me please?

masya89 [10]

Answer:
20 * 10⁻⁹

Explanation:
Assume that the number of times is t

Now, we want to know what number (t) multiplied by 2 * 10¹⁴ will result in
4 * 10⁶

Translating this into an equation:
2 * 10¹⁴ * t = 4 * 10⁶

Solving for t:
t = (4 * 10⁶) / (2 * 10¹⁴)
t = 20 * 10⁻⁹

Hope this helps :)
