Data? I need the data! Not trying to provoke, but in order to answer this I need data...
Answer:

Step-by-step explanation:
The projectile has constant horizontal speed all the time and we can use this formula
x=Vax*t, where t is time it (projectile) takes to reach x=1000m
t=x/Vax=1000/50=20s
As we know we can split projectile trajectory in two parts and the time for each part is equal. We can conclude that time t=20s belong to first part where projectile is going up.
Formula for this type of movement is y=Vay-(gt∧2)/2
If we take acceleration of gravity g=10m/s∧2
we get y=200*20-(10*20∧2)/2=4000-2000=2000m
But if I calculate time it takes the highest point I get
t=Vay/g=200/10=20s
The highest point for that time is
y= H=Vay∧2/2g=200∧2/2*10=40000/20=2000m
This happened because the projecile is fired from the edge of a cliff which is above the sea line.
Good luck!!!
2. The mean is the average so it phase shifted up five points where as the range is the difference between the highest and lowest # which wouldn't change if all the numbers were adjusted.
Answer:
option A) New cars and used cars is correct option.
Step-by-step explanation:
loan Interest rate can be defined as the percentage of a loan paid by borrowers to lenders. For most loans, interest is paid in addition to principal repayment in order to compound over time.
since new cars have more price than old cars that's why new cars have more greater loan interest than old cars
hence option a is correct
