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.
Draw a right triangle. The cat represents a side, the bird represents a side. Then just use the Pythagorean Theorem to find the hypotenuse. a^2 + b^2 = c^2. Let a = cat; b = bird; then solve for c.
The question which ask to select among the choices the equation that Alejandria should write to represent the new line where as the equation she wrote is y-3=x-10 and the answer would be that the form in this equation is y=x-13 and if the slope is 2 then it is y=2x-13
