B

`2sqrt(t)-8`

C

`(sqrt((4t-8)))/(4)`

D

The correct Answer is:
To find the formula for \( g(f(h(t))) \), we will follow these steps: 1. **Identify the Functions**: - \( f(t) = \sqrt{t} \) - \( g(t) = \frac{t}{4} \) - \( h(t) = 4t - 8 \) 2. **Calculate \( h(t) \)**: - We already have \( h(t) = 4t - 8 \). 3. **Calculate \( f(h(t)) \)**: - Substitute \( h(t) \) into \( f(t) \): \[ f(h(t)) = f(4t - 8) = \sqrt{4t - 8} \] 4. **Calculate \( g(f(h(t))) \)**: - Now substitute \( f(h(t)) \) into \( g(t) \): \[ g(f(h(t))) = g(\sqrt{4t - 8}) = \frac{\sqrt{4t - 8}}{4} \] 5. **Final Result**: - Therefore, the formula for \( g(f(h(t))) \) is: \[ g(f(h(t))) = \frac{\sqrt{4t - 8}}{4} \]
