Answer:
t=4 seconds to reach the cannon floor
Step-by-step explanation:
ax^2+bx+c=0
0=-16t^2+255
-255=-16t^2
t^2=15.9375
t= 3.99
round it up...
t=4 seconds to reach the cannon floor
hope this helps!!! :)
Answer:
It will take approximately 34 years
Step-by-step explanation:
If a town population is 8000 and grows 3% annually.
How long will it take to reach 16300
growth is 16300 - 8000 = 8300
using simple interest formula
SI = (P × r × t)/100
8300 = (8000 × 3 × t)100
8300= (80 × 3)t
8300 = 240t
t = 8300/240
t ≈ 34 years to the nearest tenth
The range is the simplest measure of variation . It is the difference between the biggest and smallest random variable.
Range= maximum value - minimum value
ex. Therefore in the range of these variables: (2,4,4,7} you would do 7 minus 2
Answer:
100
Step-by-step explanation:
103.37 and after rounding off to nearest tenth it becomes 100
