Answer:
Correct answer: Db = 411 .18 ft
Step-by-step explanation:
Given:
α = 27° angle of depression
Dt = 462 ft distance from the top of lighthouse to the boat
Db = ? distance from the base of the lighthouse to the boat
Here we have a right triangle with hypotenuse Dt and one leg Db.
By definition
cos α = Db / Dt ⇒ Db = Dt · cos α
Db = 462 · cos 27° = 462 · 0.89 = 411 .18 ft
Db = 411 .18 ft

Answer: B) $1.75</h3>
===================================================
Explanation:
To get the unit cost, we divide the total cost over the number of pounds.
We can do this for any row
- row one: ($17.50)/(10) = $1.75
- row two: ($35.00)/(20) = $1.75
- row three: ($52.50)/(30) = $1.75
- row four: ($70.00)/(40) = $1.75
You don't need to show all four row calculations. You can simply pick one row.
This tells us that each pound costs $1.75
Put another way: the price is $1.75 per pound
