Item 4 Compounds A and B are used in an experiment. The equation y=500(0.5)x represents the remaining amount of compound A, in grams, after x hours. The table shows the remaining amount of compound B. Time (h) Grams of B 1 200 2 100 3 50 What is the positive difference in the initial amount of each compound? Enter your answer in the box. g

answer: 12

step-by-step explanation:

because yes

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:
