Suppose the points (1.6) (-2,21), and (4,45) are on a parabola with equation y = ax^2 +bx+c. (a) plug each of the points into this equation to get a system of three equations (one for each point) in three unknowns (a, b,c). (b) use matlab to solve this system and obtain the equation of the parabola, (c) describe how this method would work (or not) if you only had two points that were to be on a parabola. (d) describe how this method would work (or not) if you had four points that were to be on a parabola.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
