Write the vector u as a sum of two orthogonal vectors one of which is the vector projection of u onto v, projvu u=(-9,3), v=(-9,-3).

a. (-7.2,-2.4)+(-1.8,5.4)
b. (-6,-2)+(-3,9)
c. (-9,-3)+(0,6)
d. (3,1)+(-12,2)

answer: it's d

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
