Just has to be greater than or equal to 0... w and t can never be negative since taking the square root of a negative number yields an imaginary number which would mean imaginary current. Also the question states that w can't be zero but if T is zero than the current will be zero.

Step-by-step explanation:
The quadratic formula is given by:
We can use this formula in order to solve the following equations:
1. x^2 − 2x = 12 → a = 1, b = −2, c = −12
For this case if we apply the quadratic formula we got:
2. 1/2x^2 − 6x = 2 → a = 1 / 2, b = −6, c = −2
For this case if we apply the quadratic formula we got:
3. 2p^2 + 8p = 7 → a = 2, b = 8, c = −7
For this case if we apply the quadratic formula we got:
4. 2y^2 + 3y − 5 = 4 → a = 2, b = 3, c = −9
For this case if we apply the quadratic formula we got:

Answer:
50%
Step-by-step explanation:
There are 6 sides on the die. 3 of the sides have even numbers (2,4,6) and 3 of the sides have odd numbers (1,3,5). Since there are the same amount of odd numbers as even numbers on the die, you have an equal chance rolling an even number as you do for an odd number. In other words, you have a 50% chance of rolling an odd number.
Hope this helps! :D

Answer:
265 yd squared
Step-by-step explanation:
We can solve this problem by taking the little triangle on the left side and moving it to the right to get a rectangle, and from there we can find the area like its a rectangle
