A roller coaster travels 350 feet horizontally and then travels 130 feet at an angle of 60 degrees from the ground. What is the magnitude of the resultant vector?

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position

Simplify this expression. 8x 16(x + y)
