Answer is 3 seconds
When the bullet reaches the ground, ground being x in graph (and here its s which is = 0)
s = -16t^2 + 48t
s = 0, solve for t
0 = -16t^2 + 48t
0 = t ( -16t + 48)
0 = 16t ( - t + 3)
now you have two equation
0 = 16t and 0 = -t +3 ( you can look at the graph line touches x twice)
0 = 16 t
0 = t ( you know its false, because time = 0)
You are left with
0 = -t + 3
t = 3
It takes 3 seconds for the bullet to return to the ground.

Answer:
30.6%
Step-by-step explanation:
10.75/15.5 = x/100
0.69354838709 x 100 = x = 69.3548387097
100% - 69.3548387097% = 30.6451612903% discount
Answer:
The correct answer is 2,4,6,8 and 0.
Step-by-step explanation:
A number is considered a multiple of 2 when it contains the number 2 repeated several times.
For example the number 8, contains the number 2 repeated 4 times = 2 + 2 + 2 + 2 = 8
It can also be a multiple of 2, any number multiplied by two. For example 6 is a multiple of 2 since 2x3 = 6
In simple words, all even numbers, or all numbers multiplied by 2, are multiples of 2.
2x0 = 0
2x1 = 2
2x2= 4
2x3 = 6
2x4 = 8
2X5 = 10 ...
