statistical midels predict that price p (in dollars) of a new smartphone will change according to the function p= 900-4t^2, where t is the number of months since jan. which expression gives the month t in terms of the price p?
To find an expression for the month t in terms of the price p, we need to rearrange the equation p = 900 - 4t^2.
Start by isolating the term 4t^2 by subtracting p from both sides of the equation:
900 - p = 4t^2
Now, divide both sides of the equation by 4 to solve for t^2:
(900 - p) / 4 = t^2
Finally, taking the square root of both sides of the equation, we can find the expression for t in terms of p:
t = √((900 - p) / 4)
Therefore, the expression for the month t in terms of the price p is t = √((900 - p) / 4).
