As stated in the strategy, choose a coordinate system where the x axis is horizontal and the y axis is vertical. note that in the strategy, the y component of the projectile's acceleration, ay, is taken to be negative. this implies that the positive y axis is upward. use the same convention for your y axis, and take the positive x axis to be to the right. where you choose your origin doesn't change the answer to the question, but choosing an origin can make a problem easier to solve (even if only a bit). usually it is nice if the majority of the quantities you are given and the quantity you are trying to solve for take positive values relative to your chosen origin. given this goal, what location for the origin of the coordinate system would make this problem easiest?

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
