The answer to the question is a
The rule to remember for this problem is: i^2 = -1
(4 + i)(1 - 5i)
4 - 20i + i - 5i^2
4 - 19i + 5
9 - 19i
Answer: Okay so do 3x7.5 then 3x11.5 then 7.5x11.5 then add it up and you should get 143.25
14 is how many bottles you can fill
Answer:
.
Step-by-step explanation:
Let m represent meters and h represent hours.
We have been given that Captain Brain and Mr. Pinky start 1500 meters below the surface of the water and ascend at 37 meters per hour.
Since the submarine ascends at a rate of 37 meters per hour, so elevation of submarine after h hours would be
.
Since the elevation under water surface is negative, so 1500 meters below the surface of water would be
.
The final elevation in meters of submarine after h hours would be initial elevation plus change in elevation after h hours that is
.
Therefore, the equation
. represents the given scenario.
