Answer:
At the end of 7 days, it will have gained 5 minutes and 36 seconds.
Step-by-step explanation:
This question can be solved using a rule of three.
It gains 8 minutes every 10 days. How much does it gains every 7 days?
7 days - x minutes
10 days - 8 minutes
Each 7 days, it gains 5.6 minutes. That is, it gains 5 full minutes, plus 0.6 = 60% of a minute, in seconds.
A minute has 60 seconds. 0.6*60 = 36
So
At the end of 7 days, it will have gained 5 minutes and 36 seconds.
.6, 2/3, .7, .07, .28, 7/8
I hope this helped.
"polynomial function f(x) has a leading coefficient of 1"
So because of that, we can eliminate A and B.
Now we have "root –5 with multiplicity 3"
That's just product of three factors (x+5)
So D is wrong.
We are left with the only possible correct option C.
C is f(x)= (x + 5)(x + 5)(x + 5)(x + 4)(x – 2)(x – 9)<span>

Answer is: C: f(x)= (x+5)(x+5)(x+5)(x+4)(x-2)(x-9)
Have an amazing day!
