Answer:
No restriction
Domain:
Step-by-step explanation:
We are given function as
we know that this is exponential function
and x+4 as an exponent over e
so, we can select any real values of x as an exponent
and this function will be defined for all values of x
so, there won't be any value of x where f(x) is undefined
So, domain would be
Answer:
504 different ways
Step-by-step explanation:
There are 9 people competing
9 Different people can come in 1st
We have a winner
Now there are only 8 people left to come in second
8 different people can come in 2nd
There is 1 second place winner
Now there are only 7 people left to come in second
7 different people can come in 3rd
9*8*7 =504
There are 504 different ways
True since only one from the first goes to one from the second

Answer:
Step-by-step explanation:
On the return trip from the beach, you pedal hard for the first ten minutes and cover 4 miles.
Speed = distance covered/time taken
This means that your speed for the first 4 miles would be
4/10 = 0.4 miles per minute
Tired, you slow down and cover the last 6 miles in 36 minutes. This means that your speed for the last 6 miles would be
6/36 = 0.17 miles per minute
Therefore, your average speed for the return trip would be
(0.4 + 0.17)/2
= 0.285 miles per minute
