![### Calculus Problem: Find the Second Derivative
Given:
\[ h(x) = (10 - x^2)(5x + 17) \]
we are asked to find the second derivative of the function \( h \).
First, determine the first derivative \( h'(x) \).
\[ h'(x) = \frac{d}{dx}[(10 - x^2)(5x + 17)] \]
To find \( h'(x) \), we need to use the product rule, which states:
\[ \frac{d}{dx}[u \cdot v] = u' \cdot v + u \cdot v' \]
where \( u = (10 - x^2) \) and \( v = (5x + 17) \).
Next, find the first derivative of each function:
\[ u = 10 - x^2 \quad \Rightarrow \quad u' = -2x \]
\[ v = 5x + 17 \quad \Rightarrow \quad v' = 5 \]
Apply the product rule:
\[ h'(x) = (-2x)(5x + 17) + (10 - x^2)(5) \]
\[ h'(x) = -10x^2 - 34x + 50 - 5x^2 \]
\[ h'(x) = -15x^2 - 34x + 50 \]
Now, we find the second derivative \( h''(x) \), which is the derivative of \( h'(x) \):
\[ h''(x) = \frac{d}{dx}(-15x^2 - 34x + 50) \]
\[ h''(x) = -30x - 34 \]
Thus, the second derivative of the function \( h \) is:
\[ h''(x) = -30x - 34 \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7369c9e1-cd27-40fa-b19e-4e793313e403%2F646efe56-3cab-4780-b226-d4712ded4a53%2Fpy05bvu.png&w=3840&q=75)
