Final answer:
To solve for d in the equation t = √(hd - 2q), square both sides, add 2q to both sides, and divide by h. The correct answer is d = (t² + 2q) / h.
Step-by-step explanation:
To solve the equation t = √(hd - 2q) for d, you will first need to square both sides of the equation to eliminate the square root.
This leaves us with t² = hd - 2q. Next, you can isolate d by adding 2q to both sides and then dividing by h, giving us d = (t² + 2q) / h. Therefore, the correct answer is (a) d = (t² + 2q) / h.
