It will take 13 seconds for the golf ball to hit the ground. The correct answer between all the choices given is the last choice or letter D. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
It is 13, because if you use the formula that you learned, Simplify and then turn the factors to 0 to get the answer. H(t)= -16t^2 - 208t H(t)= -16t(t-13) -16t/-16= 0/16= t=0 t-13=0 t=13
Distance formula : sqrt (x2 - x1)^2 + (y2 - y1)^2 (212,23)...x1 = 212 and y1 = 23 (6,23)......x2 = 6 and y2 = 23 now we sub d = sqrt ((6 - 212)^2 + (23 - 23)^2) d = sqrt ((- 206)^2 + (0^2)) d = sqrt (42436 + 0) d = sqrt 42436 d = 206 miles <==
B. Similar- Angle Angle Similarity Theorem This theorem states that if 2 angles of a triangle are congruent to two angles of another triangle, then the two triangles are similar. Hope this helps :)
