The cost C (in dollars) of producing x DVD players is represented by C-4.5x2. How many DVD players are produced if the cost is $544.50?
is that the anwser
wait im so confused
oobleck showed you how to do it. Finish it by doing what I said.
To find the number of DVD players produced if the cost is $544.50, we need to solve the equation C = 544.50, where C represents the cost and x represents the number of DVD players.
Given that the cost C is represented by the equation C = -4.5x^2, we can substitute this into the equation C = 544.50:
-4.5x^2 = 544.50
To solve for x, we need to isolate x on one side of the equation.
First, divide both sides of the equation by -4.5:
x^2 = 544.50 / -4.5
Simplifying further:
x^2 = -120.99999999999999
Now, take the square root of both sides to find x:
x = sqrt(-120.99999999999999)
Here is where we encounter a problem. The square root of a negative number is not a real number. Hence, there is no real solution to this equation.
Therefore, it is not possible to produce DVD players if the cost is $544.50 using the given equation.
really? Just solve for x in
4.5x^2 = 544.50
no
divide both sides by 4.5
take the square root
THINK !!!
