a model for the performance of a stock is P= -2.5d^2+50d where d represents the days of trading and P is the price per share. What is the maximum price per share of stock and after how many days of trading did this price occur?

The maximum price per share is $250 and it happens after 10 days of trading.

Step-by-step explanation:

The performance of a stock is modeled by the function:

Where d is the number of days of trading and P is the price per share.

To find the maximum price, we use the first derivative:

Equating to zero:

-5d+50=0

Solving for d:

-5d = -50

d = -50/(-5) = 10

d = 10

The price for d=10 is:

The maximum price per share is $250 and it happens after 10 days of trading.

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
