Solution A has a volume of 20 mL and a mass of 40 g Solution B has a volume of 25 mL and a mass of 75 g. Which solution is more dense? Show the math you used to find out.

a² + b²= c²

24² + 7² = c²

c= 25

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:

thus, the first answer choice, y = sec x, is the correct one

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
