Step-by-step explanation:
Answer:
C(t)=5000 -10t
Step-by-step explanation:
There are many examples in the real world of relationships that are functions.
For example, imagine a tank full of water with a capacity of 5000 liters, this tank has a small hole, by which 10 liters of water are lost every hour.
If we call C the amount of water in the tank as a function of time, then we can write the following equation for C:

Where:
C (t): Amount of water in the tank as a function of time
: Initial amount of water in the tank at time t = 0
a: amount of water lost per hour
t: time in hours
Then the equation is:
The graph of C (t) is a line of negative slope. This relation is a function since for each value of t there is a single value of C.
Its domain is the set of all positive real numbers t between [0,500]
Because the time count starts at t = 0 when the tank is full and ends at t = 500 when empty
Its Range is the set of all positive real numbers C between [0,5000] Because the amount of water in the tank can never be less than zero or greater than 5000Litres
Answer:
Mr. Herrera will hike 78 miles on 6th day.
Step-by-step explanation:
Given:
Number of miles Mr. Herrera will hike in 9 days = 117 miles
Total Number of days =9 days
Let us first find the number of miles he will hike in 1 day
By Using Unitary method we get,
Number of miles Mr. Herrera will hike in 1 days= 
We need to find miles hiked in 6th day.
Number of miles Mr. Herrera will hike on 6th day= Number of miles Mr. Herrera will hike in 1 days
Number of days =
