Answer:
cool dude surface of area cylinder of circle surface
81 * 1 / 27^y = 9 ^2y+1
81 * 1 / 9^3y/2 = 9 ^ 2y+1
9^3y/2 * 9 ^ (2y+1) = 81
9 ^ ( 3y/2 + 2y + 1) = 81 = 9^2
3y/2 + 2y + 1 = 2
7y/2 = 2 -1 = 1
7y = 2
y = 2/7 answer
Answer:
52x+135.74=265.74
4x+3=67
29.95+15.75=187.45
Step-by-step explanation:
52x+135.74=265.74
4x+3=67
29.95+15.75=187.45
What you need to do here is a vector addition of the ship's velocity with respect to the water (V1), plus the velocity of the water with respect to land (V2).
Also remember that:
<span>i = unit vector east </span>
<span>j = unit vector north </span>
<span>V1 = 30 sin 192 i + 30 cos 192 j </span>
<span>V2 = 14 sin 112 i + 14 cos 112 j. </span>
The formula will look like this
<span>V1 + V2 = ?
Now please use the data to put the values into correct places and there you go! Hope this helps</span>
