Answer:</h3>
- y = -(x -3)² +3 . . . . (agrees with your answer)
- see the attachment for a graph
<h3>
Step-by-step explanation:</h3>
Factoring the leading -1 from the first two terms, we have ...
... y = -(x² -6x) -6
Adding 9 inside parentheses to complete the square, then adding the opposite amount outside parentheses, we have ...
... y = -(x² -6x +9) -6 +9
... y = -(x -3)² +3
A6 = -8
a15= -62
There are (15 - 6) terms in between, therefore 9 terms in between.
-8 to -62 ... there is a difference of 54
54 ÷ 9 = 6
Therefore it gets -6 each term.
a6 = -8, a7= -14, a8 = -20 ......
When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.
<h3>What is a deductible?</h3>
It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.
From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.
When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:
= (4000/18000) × 1000
= $220
