<u>Exponential Equations</u>
Solve:
Separate each exponential:
Operating:
Multiplying by 5:
Rearranging:
Recall that:
Calling
Factoring:
There are two possible solutions:
y=25
y=-50
Since
y cannot be negative, thus:
The solution is:
x = 2
Since there are 
in a circle, and central 
, you can see that the part "sliced out" by the central angle is 
of the whole circle.
This means that the length of the intercepted arc
is 
of the circumference of the circle. So,
This means that the length of the intercepted arc
