Answer: A. 88 turtles
To find this, multiple 110 x .80
This is easier than multiplying 110 by .20 because you don’t have to subtract.
110 x .80 = 88
(7x+12y)(7x-12y)

Answer:
i found the question mark ;)
Step-by-step explanation:
Answer:
1600
growth
4%
Step-by-step explanation:
To solve this question, you must know what the equation really means.
P = population
t = time
1600 = initial population size
1.04 = is the percentage growth, (growth because it is greater than 1.)
So, the initial population size is 1600.
It is growth because the percentage is greater than 1.
(1.04 = 104%, 104%-100%=4%)
The population changes by 4%
A function
is periodic if there is some constant
such that
for all
in the domain of
. Then
is the "period" of
.
Example:
If
, then we have
, and so
is periodic with period
.
It gets a bit more complicated for a function like yours. We're looking for
such that
Expanding on the left, you have
and
It follows that the following must be satisfied:
The first two equations are satisfied whenever
, or more generally, when
and
(i.e. any multiple of 4).
The second two are satisfied whenever
, and more generally when
with
(any multiple of 10/7).
It then follows that all four equations will be satisfied whenever the two sets above intersect. This happens when
is any common multiple of 4 and 10/7. The least positive one would be 20, which means the period for your function is 20.
Let's verify:
More generally, it can be shown that
is periodic with period
.
