Sally's cat is stuck in a tree 18 ft off the ground. the base of a ladder is placed 6 feet away from the base of the tree. what is the minimum length ladder needed to reach the cat (rounded to the nearest foot)? a) 18 ft b) 19 ft c) 20 ft d) 21 ft

What is the nth term rule of the linear sequence below? 27 , 25 , 23 , 21 , 19 , . .

Which sum or difference identity would you use to verify that cos (180° - ∅) = -cos ∅? a. sin (α -β) = sin α cos β – cos α sin β b. cos (α -β) = cos α cos β – sin α sin β c. cos (α -β) = cos α cos β + sin α sin β d. sin (α + β) = sin α cos β + cos α sin β

Tcan be concluded that % of the seniors would prefer to see more candid pictures in this year's edition of the yearbook.
