An astronaut drops a rock off the edge of a cliff on an alien moon. The distance, d(t) in meters, the rock travels after"t" seconds can be modeled by the function d(t)=-0.3(t)^2+90. How high is the cliff from the surface of the moon, and how do you know? What is the average speed, in meters per second, of the rock between 5 and 10 seconds after it was dropped?

20+ ! come and answer quick! triangle mno is reflected over the x-axis and then translated up 4 and right 3. how can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? a translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis. b translate the pre-image up 3 and right 4 and then reflect the figure over the x-axis. c translate the pre-image up 4 and left 3 and then reflect the figure over the y-axis. d translate the pre-image down 3 and right 4 and then reflect the figure over the x-axis.
