Answer:
y = 3n + 70 - 35 or y = 3n + 35
Step-by-step explanation:
you get 3n bc she gets 3 rocks per hike(n)
you get 70 - 35 or just 35 bc she started with 70 then gave half away and half of 70 is 35
In a function, every input has one and only one output.
if -5 is your input, then 5 is the output
if 8 is your input, then 0 is your output
multiple inputs can lead to the same output, like
-6 as the input can give an output of 7
and also -7 as the input can give an output of 7
however, multiple one input cant not have multiple outputs.
since none of those values share the same x values with different y values, the relation is in fact a function.
the answer should be true
The amount remaining (Q(t)) can be expressed in terms of the initial quantity Q₀ and the number of days (t) by
Q(t) = Q₀×0.82^t
Filling in the given numbers, you have
13 = Q₀×0.82^11
13/0.82^11 = Q₀
Q₀ ≈ 115.34 . . . . milligrams
