Answer:
<em>a) the angle of ascent is 8.2°</em>
<em>b) the horizontal distance traveled is 4375 m</em>
Step-by-step explanation:
depth of ocean = 626 m
distance traveled in the ascent = 4420 m
This is an angle of elevation problem with
opposite side to the angle = 626 m
hypotenuse side = 4420 m
a) angle of ascent ∅ is gotten from
sin ∅ = opp/hyp = 626/4420
sin ∅ = 0.142
∅ = 0.142
∅ = <em>8.2° this is the angle of ascent of the submarine.</em>
b) The horizontal distance traveled will be gotten from Pythagoras theorem
= +
The horizontal distance traveled will be the adjacent side of the right angle triangle formed by these distances
= +
adj =
adj = <em>4375 m this is the horizontal distance traveled.</em>
The answer is 4/9 that is the answer hahahahah
The first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25

R + 4D < = 64 (thats less then or equal)....and R = regular and D = deluxe
