1 song: 0.99
2 songs: 0.99 + 0.99 = 2 * 0.99
3 songs: 0.99 + 0.99 + 0.99 = 3 * 0.99
...
n songs: 0.99 + .. 0.99 ( n times) = n * 0.99 = 0.99n

Answer:
The value of
is
.
Step-by-step explanation:
We know that the position function is given by

Velocity is defined as the rate of change of position. Therefore,

So, the velocity function is

When a body reaches a vertical velocity of zero, this is the maximum height of the body and then gravity will take over and accelerate the object downward. Thus,

We know that the ball bearing reaches its maximum height 21 seconds after being launched (t = 21 s).
So, the value of
is
.
Answer:
80%
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((36 - 20) / 20) * 100 = 80 %
Answer:
A: P = 41100 - 590t
B: 34610
Step-by-step explanation:
equation = 41100-(41100-36380)/(2011-2003)t
plug it in
41100 - 590(2014-2003)=34610
