Answer:
18,223 feet
Step-by-step explanation:
y= -16t^2 + 608t + 12,447.
y = -16(t² - 38t) + 12447
y = -16[t² - 2(t)(19) + 19² - 19²] + 12447
y = -16(t - 19)² - 16(-19²) + 12447
y = -16(t - 19)² + 18223
Vertex: (19, 18223)
Max height is 18,223 at t = 19
The ratio will be 100/20 or 5:1. Read as for every 5 purple disks , there is 1 green disk.
Pretend DK and ML are parallel lines. Then MK is a line crossing the parallel lines. Angles KML and DKM would be alternate interior angles there fore the angle would be the same, 82.
