Step-by-step explanation:
the value in the y axis moves by the same amount each time.
Answer:

Explanation:
The question is "Einstenium-253 is an element that loses about 2/3 of its mass every month. A sample of einstenium-253 has 450 grams. Write a function that gives the sample's mass in grams, S(t) from today".
Since <em>einstenium-253 loses about 2/3 of its mass every month</em>, you can model the amount of sample by an exponential decay function, which is a geometric progression with a growing factor less than 1.
The general form of an exponential decay function is:

Where:
- A₀ is the initial value
- r is the growing or decaying factor
- t is the time
- y is the value of the function at time t.
In this case, you have:
- A₀ = 450
- r = 2/3
- t = t
- y = S(t)
Now you can replace the values in the model and will obtain:

84 kilometers ... 1 hour
7 kilometers ... x hours = ?
If you would like to know how long does the pigeon take to fly 7 kilometers, you can calculate this using the following steps:
84 * x = 1 * 7
84 * x = 7 /84
x = 7/84
x = 1/12 hour
Result: A pigeon can fly 7 kilometers in 1/12 hour.
