Express the terms of the following sequence by giving an explicit formula. A. u(n) = 4 + 6n, where n = 1, 2, 3, 4, . . . B. u(n) = 6 - 4n, where n = 1, 2, 3, 4, . . . C. u(n) = 4n, where n = 1, 2, 3, 4, . . . D. u(n) = n + 4, where n = 1, 2, 3, 4, . . .

i think the answer is b.

step-by-step explanation:

not 100% sure though.

idk lol xd

step-by-step explanation:

ez do it yourself lazy

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)
