Answer:
The graph is attached.
Step-by-step explanation:
The exercise says that Elon took 35 seconds to pull the boot up to the surface, how the constant rate is:
- Constant rate: 0.1 meters per second.
To know the meters below the surface that is the boot, we multiply the constant rate by the time Elon took to pull up it:
- Boot depth = 0.1 m/s *35 s
- Boot depth = 3.5 meters.
How the boot is pulling up through the time, the formula must subtract the time from the depth, how is below:
- <u>a = 3.5 - 0.1t</u>
Where:
<em>a = depth.</em>
<em>t = time.</em>
Answer:
option D
Step-by-step explanation:
x-2y≥-12
-2y≥-x-12
y≤0.5x+6
has to be a solid line since y is less than or equal to 0.5x+6
so, options 1 and 3 are not applicable
also, in y≤0.5x+6 , y is less than or equal to this line, thus it only exists on the line and to the right of it (below it)
so, option 2 is wrong also, leaving us with option 4 or D, which in this case is the answer
