Ana dives into a pool off of a springboard high dive. her height (in meters above the water), xxx seconds after diving, is modeled by h(x)=-5(x+1)(x-3). what is the height of ana above the water at the time of diving?

seems like d

step-by-step explanation:

14

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
