A ship's sonar locates a treasure chest at a 12° angle of depression. A diver is lowered 40 meters to the ocean floor. How far (
anastassius [24]

Answer:

The answer to your question is 8.5 m

Step-by-step explanation:

Data

angle = Ф = 12°

dept = 40 m

distance from the ship to the treasure = ?

Process

To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

                      tan Ф = Opposite side / Adjacent side

-Solve for Opposite side

                      Opposite side = Adjacent side x tanФ

-Substitution

                      Opposite side = 40 x tan 12

-Simplification

                       Opposite side = 8.5 m

If log 6=.7781 then what is log 60,000
pashok25 [27]
By using the calculator, log 6 = 0.7781...

log 60,000 is just equal to log (6 * 10,000)
log (6 * 10,000) = log 6 + log 10,000

As we know that log 10 = 1, log 100 = 2, log 1000 = 3, and so on.
So log 10,000 = 4

Going back to our equation,
log (6 * 10,000) = log 6 + log 10,000
log 60,000 = 0.7781 + 4

So log 60,000 = 4.7781

elijah has three neighbors the sum of all the neighbors ages is 80 the second-oldest neighbor is 28 years old the difference bet
Nata [24]

Ans:

Step-by-step explanation:

Let the age of oldest neighbour be x

let the age of youngest neighbour be x-30

According to question,

x+28+x-30 = 80

or, 2x +28-30=80

or,2x+28=80+30

or, 2x=110-28

or, 2x=82

or, x=82/2 = 41

Therefore, The age of oldest neighbour is 41 years

& The age of youngest neighbour= x-30 = 41-30 = 11 years!
