Answer:
a) -2 < 3
b) |-12| < |15| <em>(the absolute value of -12 is 12 so that's comparing 12 to 15)</em>
c) 3 > -4
d) |15| > |-12|
e) 7 > -11
The speed in feet per second is 247.5
The parachutist will fall 4950 feet during 20 seconds.
Step-by-step explanation:
Given,
Speed during free fall = 75 meters per second
It is given that,
1 meter = 3.3 feet
75 meter = 75*3.3 = 247.5 feet
Therefore;
Speed during free fall in feet = 247.5 feet per second
Now,
1 second = 247.5 feet
20 seconds = 247.5*20 = 4950 feet
Fall during 20 seconds = 4950 feet
The parachutist will fall 4950 feet during 20 seconds.

The proof that the diagram is a square is that; D: slopes are perpendicular where the sides meet
<h3>How to Prove a quadrilateral is a Square?</h3>
We know that a square is a quadrilateral that has 4 sides. Now, the 4 sides of a square are all equal and at right angles.
Since all sides of the square are equal, then it means that 2 consecutive sides must be perpendicular to each other. Thus, this means that the slope of 2 consecutive sides must be perpendicular to each other.
