Use the position formula $$ s=-16 t^{2}+v_{0} t+s_{0} $$ \(\left(v_{0}=\text { initial velocity, } s_{0}=\text { initial position, } t=\text { time }\right)\) to answer Exercises \(49-52 .\) If necessary, round answers to the nearest hundredth of a second. A projectile is fired straight upward from ground level with an initial velocity of 80 feet per second. During which interval of time will the projectile's height exceed 96 feet?
In Exercises \(29-44,\) perform the indicated operations and write the result in standard form. $$\frac{-8+\sqrt{-32}}{24}$$
In Exercises \(9-20,\) find each product and write the result in standard form. $$(-4-8 i)(3+9 i)$$
Solve each rational inequality in Exercises \(29-48,\) and graph the solution set on a real number line. Express each solution set in interval notation. $$ \frac{-x+2}{x-4} \geq 0 $$
Write a rational inequality whose solution set is \((-\infty,-4)\) or \([3, \infty)\)
