1 answer:
Answer:
Jerry does cases per hour (Rounded to 2 decimal places). As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.
Step-by-step explanation:
to find the number of cases per hour, we have to divide the number of cases by number of hours taken for those cases,
Number of cases per hour =
= cases per hour
= cases per hour
= cases per hour
= cases per hour (Rounded to 2 decimal places)
As we cannot do 0.11 cases. We can say Jerry does 2 cases per hour.

EXPLANATION
The given polynomial is
where a=1,b=k, c=30
Let the zeroes of this polynomial be m and n.
Then the sum of roots is
and the product of roots is
The square difference of the zeroes is given by the expression.
From the question, this difference is 169.
This implies that:
We substitute the values of k into the equation and solve for x.
The zeroes are given by;
