The Deep Dive
To find \( h^{\prime}(5) \), we can differentiate \( h(x) \): \[ h(x) = 2 f(x) + 5 g(x) + 5 \] Using the derivative rules, we get: \[ h^{\prime}(x) = 2 f^{\prime}(x) + 5 g^{\prime}(x) \] Now, substituting \( x = 5 \): \[ h^{\prime}(5) = 2 f^{\prime}(5) + 5 g^{\prime}(5) \] Given \( f^{\prime}(5) = 3 \) and \( g^{\prime}(5) = 6 \), we can plug those values into our equation: \[ h^{\prime}(5) = 2(3) + 5(6) = 6 + 30 = 36 \] So, \( h^{\prime}(5) = \boxed{36} \).
