so, the constant of proportionality is 3.88
Answer:


Step-by-step explanation:
The vertex form of a parabola is given as

If this parabola opens downward, then a<0.
This means for a function opening downward not to have a solution, the k value must also be negative and taking a square root of a negative number will not give real solution.
From the given options, examples of such functions are:

and

For this case we have the following equation:

To clear w, we must follow the following steps:
1) The value of t multiplied by c pass to divide the other side of the equation:
2) the value of 1000 is passed to multiply to the other side of the equation:
Answer:
The cleared equation for w is:
Answer:
