The function is graphed as shown below
Part A:
We use the formula
to find the vertex of the function. A quadratic function of the form of
and equating this form to the given function
, we have
and
.
Substituting
and
into the vertex formula, we have
, as shown in the graph
This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos
Part B:
We can find solution to this equation by factorising
and
, as shown in the graph
The two values means that the company makes no profit when they either produce 5 or 15 photos
Answer:
Step-by-step explanation:
Given
Required
Approximate (to the nearest 100th)
This means that, we approximate at the second digit after the decimal.
So:
i.e,
Number = 39.79 [Begin approximation] 949748
The first digit after [Begin approximation] is then approximated using the following rule:
Since 9 falls in category, the number becomes:
Bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
Answer:
512
