⦁find all sets of three consecutive positive odd integers whose sum is less than 22.

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

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
