1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer: The value of 2^3+5^2 is 18.
Step-by-step explanation:
2^3 = 2 × 2 × 2 = 8
5^3 = 5 × 2 = 10
10 + 8 = 18
I hope this helped! :D
Well you equal out the two angles to each other and solve for x. then you just plug the the number you got for x back into the equations to get your answers
Answer:
uh ma'am - you need help this totally make sense ^_^
