The position of a particle on the x-axis at time t, t > 0, is s(t) = et with t measured in seconds and s(t) measured in feet. what is the average velocity of the particle for 0 ≤ t ≤ in3? 3 2/ln3 3/ln3 3/2

step-by-step explanation:

jjj

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
