Answer: Rhombus</h3>
======================================================
Reason:
Let's find the distance from A to B. This is equivalent to finding the length of segment AB. I'll use the distance formula.

Segment AB is exactly
units long, which is approximately 4.1231 units.
If you were to repeat similar steps for the other sides (BC, CD and AD) you should find that all four sides are the same length. Because of this fact, we have a rhombus.
-------------------------
Let's see if this rhombus is a square or not. We'll need to see if the adjacent sides are perpendicular. For that we'll need the slope.
Let's find the slope of AB.

Segment AB has a slope of 1/4.
Do the same for BC

Unfortunately the two slopes of 1/4 and 4 are not negative reciprocals of one another. One slope has to be negative while the other is positive, if we wanted perpendicular lines. Also recall that perpendicular slopes must multiply to -1.
We don't have perpendicular lines, so the interior angles are not 90 degrees each.
Therefore, this figure is not a rectangle and by extension it's not a square either.
The best description for this figure is a <u>rhombus</u>.

Answer:
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
Step-by-step explanation:
After reviewing the information given for solving the question, we notice that the number of adults and the number of children are two constants, where the number of children is the 75% of the number of adults (3/4 = 75%). In that case, for finding the number of children for every specific number of adults, we do the following calculations:
1. For 8 adults: Using the 75%, we multiply by it (8 * 75%) and we get that the number of children is 6.
2. For 12 adults: Using the 75%, we multiply by it (12 * 75%) and we get that the number of children is 9.
3. For 16 adults: Using the 75%, we multiply by it (16 * 75%) and we get that the number of children is 12.
4. For 20 adults: Using the 75%, we multiply by it (20 * 75%) and we get that the number of children is 15.
<u>There were 6, 9, 12 and 15 children if the number of adults at the beach were 8, 12, 16 and 20.</u>
H(t)=h0+vt-(at^2)/2 we can assume that this problem is near to the earth's surface so a≈32ft/s^2
h(t)=h0+vt-16t^2 now you need to plug in the initial velocity where v is and the initial height where h0 is...
