The table shows the depth
DIA [1.3K]

Answer:

  The sub rose 121 feet.

Step-by-step explanation:

The sub was less deep at 12 pm than at 10 am, so rose in the water. The amount it rose was ...

  410 -289 = 121 . . . . feet

__

If you like, you can think of the sub's elevation relative to the surface as changing from -410 feet to -289 feet. The difference is then an increase in elevation (rise) of ...

  -289 -(-410) = -289 +410 = 121 . . . feet

_____

12 am is midnight, 14 hours after 10 am. The time 2 hours after 10 am is 12 pm, noon.

Find two unit vectors in 2-space that make an angle of 45◦ with 4i+3j.
inn [45]
First, lets transform the given vector into an unit vector (dividing by its module)


UnitVec = 4/5 i + 3/5 j

Then lets change this vector into a polar form

UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector

Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form

U = 1*[cos(
36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j


V = 1*[cos(
36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
