A square backyard is drawn below. Which of the following inequalities best represents the perimeter of the yard if it must be no less than 140 units? F. y ≥ 3x - 35 units
G. y ≤ 3x - 35 units
H. y ≥ 12x - 140 units
J. y ≤ 12x - 140 units

is this part of a question or something

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:

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
