To factor a polynomial we need to find 2 numbers that add up to -15 and multiply into -54.
(-x -18)(x +3) Will be your answer.
The answer is the bottom !hope this helps!
Answer:
2n= 53
and you divide both sides by 2
2n/2 =53/2
2 divided by 2 is 1 and 53 divided 2 is 26.5
n= 26.5
Answer:
Option A.Exponential decay, 55% decrease
we have
This is a exponential function of the form
where a is the initial value
b is the base
b=(1+r)
r is the rate of change
In this problem
a=54
b=0.45
so
0.45=1+r
r=0.45-1
r=-0.55
Convert to percentage
r=-55% ------> is negative because is a exponential decay
