<span>In general, the height of a projectile is given by
</span>
<span>
where </span>
is the height at time
of a projectile shot upward at velocity
from initial height
<span>.
The acceleration of gravity </span>
<span> We give it a negative sign in the equation because it pulls down.
Let's apply it to each group.
Group A launches a tennis ball straight up with an initial velocity of 19 meters per second.
We have MKS units, positive (upward) velocity and an initial height of 0.
</span>
<span>
Group B launches a tennis ball straight up with an initial velocity of 50 feet per second. Not metric, velocity +50, initial height zero.
</span>
<span>
Group C drops a tennis ball from a height of 19 meters.
MKS, initial height 19, initial velocity zero.
</span>
<span>
Group D drops a tennis ball from a height of 50 feet.

Answer:
D. Discount Deals Depot; $15.20
Why?
Lets do Big Bargain Bonanza first.
$8.00 would stay the same as it is for handling. The only number that would change is $1.25, it uses the the words PER pound for shipping.
Your equation would look like this with p being how many pounds Kanya is shipping:
$8.00+$1.25p
Now we just plug in the numbers.
$8.00+$1.25(6)=
$8.00+$7.50=
$15.50
The same games for Discount Deals Depot.
$9.50+$0.95(6)=
$9.50+$5.70=
$15.20
So in conclusion Discount Deals Depot; $15.20 is cheaper than Big Bargain Bonanza;$15.50
Answer:
This property would be the Associative property of addition.
3/6. If you have the same Numerator (in this case 3), the choice with the smaller denominator (6 or 8) is the larger of the numbers
