Answer:
Step-by-step explanation:
t = Time taken
u = Initial velocity =17 m/s
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
Total height the rock is to fall when it is 8 meters from the ground is 
Time taken to reach the maximum height is 1.73 s.
Time taken from the maximum height to the point which is 8 m from the ground is 2.77 s.
So, time taken from the moment of the throw to the point 8 m from the ground is 
.

Answer:
growth
Step-by-step explanation:
Exponential function represents f (x) = a ^ x
First, the derivative is f '(x) = xa ^ (x-1)
Because when a is greater than 1
(1.08>1)
The values of derivative functions are all greater than 0, so they are monotonically increasing in the domain of definition
So when the base number is greater than 1, it is an increasing function
And the larger the index, the larger the number

Answer:
220 minutes
Step-by-step explanation:
Find how many hours there are between the two times which is 3 hours then multiply 3 by 60 because there are 60 minutes in an hour
Since the time is 11:40 we also know 40 minutes have passed so add the two minutes
40+180=220
