30) Agolf ball is hit upward at 132 feet per second, or 90 miles per hour. It's height in feet after \( t \) seconds 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?

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

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

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

1. \( \lim _{x \rightarrow \infty}(\overline{3 x-5}) \) 2. \( \lim _{x \rightarrow 0}(1-\tan x)^{\frac{4 x}{\sin ^{2} 3 x}} \)

Integrate as indicated. Assume \( \mathrm{g}(\mathrm{x})>0 \) whenever \( \ln g(\mathrm{x}) \) is involved. \( \int \frac{8 \mathrm{x}}{4 \mathrm{x}^{2}+1} \mathrm{dx} \) \( \int \frac{8 \mathrm{x}}{4 \mathrm{x}^{2}+1} \mathrm{dx}= \)
