Answer:
B. $39550
Step-by-step explanation:
The expression for the function is not well-formatted, find the correct format in the solution bellow
Step one:
given data
We are told that the function of the cost is
instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above
substituting we have
$39550
We are given the quadratic:
, with a=1, b=-8, c=15.
We know that the x-coordinate of the vertex, which is the point where the line of symmetry passes through is
.
Thus, the x-coordinate of the vertex is
.
Thus, the line of symmetry is x=4.
Answer: <span>B. The line of symmetry should have been 4 instead of –4. </span>
