Answer:
the correct answer is 12n+2
Step-by-step explanation:
Given:
The graph of an invertible function 
<em> </em>is given.
To find:
The value of 
.
Solution:
We know that, if the graph of an invertible function passes through the point (a,b), then the inverse function 
passes through the point (b,a).
From the given graph it is clear that the graph of the function passes through the points 
.
So, the inverse function must be passes through the point 
.
Therefore, the value of inverse function is 
at 
. So, the value of is .
The answer is 39.60 all you have to do is add the 2 numbers together.
To solve this problem, we must assume that the man
undergoes constant acceleration as he goes down the river (therefore no other forces
must act on him except gravity). Therefore we can use the formula below to
calculate for the duration of his fall:
y = y0 + v0 t + 0.5 a t^2
where y is the distance and y0 = 0 since we set the
reference point at the bridge, v0 is the initial velocity and is also equal to
v0 = 0 since the man started from rest, therefore the equation becomes:
y = 0 + 0 t + 0.5 a t^2
y = 0.5 a t^2
Rewriting in terms of t:
t^2 = 2 y / a
t = sqrt (2y / a)
a is acceleration due to gravity = 9.8 m/s^2
t = sqrt [2 * 23 / 9.8]
t = 2.17 s
Therefore the jump last only about 2.17 seconds.
