It takes Ariel 60 minutes to reach the hiking team's campsite, following a
trail depicted in the graph at the right.
What is the change in the elevation between Ariel's starting point and the campsite?
A) 10 feet
B) 20 fect
C) 25 feet
D) 40 feet

Match each equation with the operation you can use to solve for the variable. subtract 10. divide by 10. divide by 5. subtract 18. multiply by 10. add 18. add 10. multiply by 5. 5 = 10p arrowright p + 10 = 18 arrowright p + 18 = 5 arrowright 5p = 10 arrowright

When you answer this can you explain

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)
