Answer:
To bring the submarine back to the sea level, it have to move 578 feet upwards
Step-by-step explanation:
Given:
Initially the depth the submarine dives = 657 feet below sea
The height the submarine moves up = 79 feet
To Find :
Change in its depth required to bring the submarine back to the sea level = ?
Solution :
In initially the Submarine will be at the depth of 657 feet below sea
when it goes up, the the depth reduces
657 - 79 = 578 feet
Now the submarine will be the depth of 578 feet
Now the submarine have to move 578 feet upwards to reach the sea level
-4x + 10y = -4
10y = 4x - 4
y = 2/5 x - 2/5 so slope = 2/5
-2 - 2x = 5y
5y = -2x - 2
y = -2/5 x - 2/5 so slope = -2/5
the slope is opposite so the lines are intersecting
answer is A.
Answer:
70.5°
Step-by-step explanation:
Use the law of sines.
Multiplying both sides of the equation by 6 will result
Then just use the inverse sine function on your calculator
Answer:
no
Step-by-step explanation:
to be proportional, every step of 1 in the upper row, must equal an equal step in the lower row.
from 1 to 2: +15
from 2 to 3: +18
not the same so not proportional
