Answer:
D. 14.73
Step-by-step explanation:
According to Pythagoras,
19^2 = 12^2 + x^2
x^2 = 19^2 - 12^2
x^2 = 361 - 144
x^2 = 217
x =
x = 14.73
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
