Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, proj,
u= -9,3), v = (-9,- 3)
a. (-7.2.- 2.4)+ (-18,5.4)
c. (9-3) + (0.6)
b. 4-6,-2)+(-3,9)
d. (3.1) + (-12,2)

Astuntman jumping off a 20-m-high building is modeled by the equation h=20-5t^2, where t is the same in seconds. a high-speed camera is ready to film him between 15m and 10m above the ground. for which interval of time should the camera film him?

Will give brainliestbased on the topographic map of mt. st. helens, what is the contour interval if the volcano height is 2,950 m?

Plzzz answer both questions and i will give you 100 points
