Brums [2.3K]

The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).

So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).

An object is launched upward at 64 ft/sec from a platform that is 80 feet high. What is the objects maximum height if the equati
Free_Kalibri [48]
Max height is the vertex
convert to vertex form (y=a(x-h)^2+k) by completeing the square

h(t)=-16(t²-4t)+80
h(t)=-16(t²-4t+4-4)+80
h(t)=-16((t-2)²-4)+80
h(t)=-16(t-2)²+64+80
h(t)=-16(t-2)²+144

vertex is (2,144)
at t=2, the height is 144

max height is 144ft
