Q: Relative to the origin O, the point A has position vector given by OA = i + 2j + 4k. The line l has equation r = 9i − j + 8k + u(3i − j + 2k) . Find the position vector of the foot of the perpendicular from A to l. Hence find the position
vector of the reflection of A in l.

the answer will be b x² +x-1

step-by-step explanation:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21

hope it

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
