Answer:
Step-by-step explanation:
Initial # = 176 fans
Final # = 202 fans
Increase = 202 - 176 = 26 fans
% increase = 100% x (Increase / initial #)
= 100 x (26/176)
= 100 x 0.1477
= 14.78%
4.5. because ⁼3=9, and 9 divided by 2 is 4.5
Answer:
yes ur correct its nonlinear lol
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
Distance ÷ Speed = Time
81 miles ÷ 60.4 miles per hour= 1.34 hours
1.34 hours ≈ 1 hour 20 min
