We're asked to find how high the rocket would rise in a 2 second fuse rise. This is a simple instruction that can be obtained by setting the unknown, t, in the equation to 2. Doing this, we have
-16 * 2² + 300 * 2 + 30
-16 * 4 + 600 + 30
-64 + 630 = 566 ft
Then, we can therefore conclude that the rocket will rise high up to a distance of 566 ft
Y^2+4y=-8 add 8 both sides y^2+4y+8=0 in the form of ax²+bx+c=0 Factor it by formula -b+-(√b²-4ac)/2a -4+-(√16-32)/2*1 -4+-(√-16)/2 -4+-4i/2 -2+-2i where√-1=i
