H(t)=-16t^2+24
so i have to find how long (in seconds) it will take a tool to fall to the ground from a height of 24 feet. i am using the equation h(t)=-16t^2+24 to find it but i'm not sure how to solve it or where to even get started! any would be great you!

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

this doesn't make sense lol
