14 - (-270) - 69 + 10 = 14 + 270 - 59 = 284 - 59 = 225;
The time it takes between when the rock was dropped and when it landed is 1.33 seconds.
<h3>What is the time it takes for the rock to land?</h3>
The time it takes the rock to land on the ground from where it is dropped can be determined by using the function given.
The height of the function when it hits the ground will be zero, so the function can be written as:


64 = 36t²

t² =1.778

t = 1.333 seconds

The appropriate units to measure the thickness of a playing card would likely be millimeters.
Solution: Let x be the total space of hard drive.
We are given 80% space of hard drive is full and 12000 megabytes are free.
We can write:





megabytes
We have to free 5% of space as the difference between 80% and 75% is 5%.
Therefore 5% of 60000 is:

We know that 1 minute of video uses 60 megabytes of space.
Therefore number of minutes of video that should be deleted to make 75% of space free is:
minutes of video
Hence, 50 minutes of video should be deleted so that the hard drive is 75% full.
Work shown above!
The Midpoint would be ( -1, 6)
Hope this helps!!! c:
