Find the unit tangent vector t(t) at the point with the given value of the parameter t. r(t) = 2te−t, 6 arctan(t), 3et , t = 0

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)

step-by-step explanation:

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
