4. The trajectory of a model rocket can be modelled by the equation h = - 3t^2 + 24t- 25, where h is the height of the rocket in meters, and t is time after launch in seconds. Determine when the rocket is at the highest point. ​

Write an equation of a line in slope intercept form that is perpendicular to the line 2x -3y = 12 and passes through the point (2, 6).

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
