This shows the recursive formula for a sequence. an = an – 1 + 5
a1 = –4
Which function can be used to determine the nth term?

f(n) = –9 + 5n

f(n) = –4n

f(n) = n + 5

f(n) = 5 – 9n

answer:

what is your question that you ask

step-by-step explanation:

you need to give us more information since we can't answer

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)
