Megan gets ready to launch the same rocket from a platform 21 feet above the ground with the same initial velocity. how long will the rocket stay in the air this time?
a. write a function that represents the rocket's path for this launch.
b. factor the corresponding equation to find the values for t when h is zero.
c. erin says that the roots of the equation are t = 5.25 and t= -20.25 and that the rocket will stay in the air 5.5 seconds. megan says she is wrong. who is correct? how do you know?

its definatley   this on your answer choice?

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.
