- Given the vectors i =(- 3, 7, 4] and y = [- 6, 0, 8], determine b) proj „ . a) The angle between i and ỹA box containing basketball equipment is sitting on a shipping pallet. The box plus the contents weighs 40.0 newtons [N], and the pallet weighs 155 newtons [N]. The box can be modeled as a rectangular parallelepiped and has the following dimensions: 3 inches [in] by 15 inches [in] by 20 inches [in]. Assume the pallet is also a rectangle and has the following dimensions: 4 feet [ft] by 3.5 feet [ft] by 0.25 feet [ft]. The box is sitting on the pallet in the configuration shown below.

(Round your answer to four decimal places.)The length of the slope of a mountain is 2750 m, and it makes an angle of 13.4° with the horizontal. What is the height of the mountain, relative to its base?
- You are wondering how high that hawk is, surveying your back yard from a perch at the top of an oak tree toward the back property line. Remembering that you learned about vectors in physics, you measure off two components of a vector from your feet to the bird. Let "x" be parallel to the back of your house, and "y" perpendicular to the house out to the base of the tree. The vector to the bird would be (x, y, z). If x is 49 and y is 70 meters, what would z be in meters such that the angle from your feet to the bird is 45 degrees?The length of the slope of a mountain is 2690 m, and it makes an angle of 10.0° with the horizontal.
