Answer:
$1571
Step-by-step explanation:
If we assume that y is profit in dollars, the maximum value of y is revealed by a graph to be ...
ymax = $1571
The maximum profit the company can make is $1571 at a selling price of $45 each.
_____
The function can be written in vertex form as ...
y = -(x^2 -90x) -454
y = -(x^2 -90x +45^2) -454 +45^2
y = -(x -45)^2 +1571
Because the leading coefficient is negative, we know this vertex represents a maximum. (x, y) = (45, 1571) at the vertex. Maximum profit is $1571.
Answer:
The diver will be in free fall for seconds.
Step-by-step explanation:
The distance in feet, that an object falls in t seconds is given by the function .
Now, given that the height is 4800 feet and we have to calculate the number of seconds the diver was in a free fall.
Therefore,
⇒
⇒ seconds.
Therefore, the diver will be in free fall for seconds. (Answer)
