A0) golf ball is hit upward at 132 feet per second, or 90 miles per hour. It's height in feet after given by \( h(t)=-16 t^{2}+132 t \) a. When does the golf ball reach its maximum height? b. What is the maximum height?

Determina los sguientes \( \lim _{x \rightarrow-4}(6-3 x) \)

1) \( \int_{8}^{\frac{\text { III }}{\frac{\pi}{2}}} x \cdot c \)

7.- Resuelve el siguiente límite * \( \operatorname{lí}_{t \rightarrow 1}\left(\frac{t^{2}+2 t+1}{2 t-4}\right) \) 2 -3 -2 3

9.- Calcula la derivada de la función * \( y=\left(x^{2}+b^{2}\right)^{4} \) \( \begin{array}{ll}\text { A) } \frac{d y}{d x} 8 x\left(x^{2}+b^{2}\right)^{5} & \text { B) } \frac{d y}{d x} 8 x^{2}\left(x^{2}+b\right)^{3} \\ \text { C) } \frac{d y}{d x} 8 x\left(x^{2}+b^{2}\right)^{3} & \text { D) } \frac{d y}{d x} 8\left(x^{2}+b^{2}\right)^{3}\end{array} \)

Find \( (A) f^{\prime}(x) \), (B) the partition numbers for \( f^{\prime} \), and \( (C) \) the critical numbers of \( f \). \( f(x)=x^{3}-12 x-8 \) (A) \( f^{\prime}(x)=\square \) (B) Find the partition numbers for \( f^{\prime} \).
