1 zero pair of 25 was added to bring given function into vertex form.
<h3>What is a Zero Pair ?</h3>
A zero Pair is the set of two numbers which when added together gives 0.
The function given is
f(x) = x² -10x -4
To convert it into the vertex form
y = a(x-h)² +k
f(x) = x² -10x +25 -25 -4
f(x) = x² -10x +5² -25-4
f(x) = (x-5)² -29
Therefore this is the given function's vertex form and
1 zero pair of 25 was added to bring it into that.
Therefore Option D is the answer.

Answer: 112.32
Step-by-step explanation:
2(b + 3c) → We first need to simplify this.
Simplify.
2b + 6c
1st Option :
3(b + 2c)
Simplify.
3b + 6c
This is INCORRECT, as it is not equal to 2b + 6c.
2nd Option :
(b + 3c) + (b + 3c)
Simplify.
2b + 6c
This is CORRECT because 2b+6c = 2b+6c
(b + 3c) + (b + 3c) → Answer

Answer:you know that N=0.41No so if you sub that in the No's cancel and you get 0.41=e^-kt.
solving for t you get t=(ln0.41)/(-k)=8915.98=8916 (to the nearest year)
