Answer:
The time the object takes to fall on the ground from 224 feet is 3.74 s.
Step-by-step explanation:
In this case we have a known quantity, the distance of the fall that is 224 feet and a equation that represents the motion of this fall that is d = 16t^2. We wish to find the time it'll take this object to fall, so we can solve this equation for t. It goes as follows:
d = 16t^2
d/16 = t^2
t^2 = d/16
t = \sqrt(d/16)
t = [\sqrt(d)]/4 = [\sqrt(224)]/4 = 14.97/4 = 3.74 s
where \sqrt is the square root of the number.
You write .63/1 or (63/100) but since you can't really do anything with that, you move the decimals so that it's a whole number but you have to move the decimal the same amount of times with the one. So since you move 2 times so that it's 63, you do the same with the one=100. So the answer is 63/100

Again we do the vertical line test. Every vertical line must intersect at most one point for the graph to be a function. That fails for all but the first one, top left.
