Determine the average rate of change for the following questions. Show your work.

1. It takes a rocket 30 seconds to travel 1 mile above the earth’s surface and 1 1/2 minutes to travel 6 miles. What is the rate of change per second for the entire trip?

2. What is the rate of change for the same rocket to complete its trip after the first mile?

3. Graph both answers; show the rate of change for the first mile and the rate of change after the first mile. (y = 2 1/2 units equal one mile, x = one unit equals 10 seconds)

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down

How can i differentiate this equation?
