Answer:
5.90551
Step-by-step explanation:
(88sin20)(t - 16t²) = 0
(8(0.3090169944)(t - 16t²) = 0
(2.472135955)(t - 16t²) = 0
2.472135955t - 39.55417528t² = 0
Pythagoras:
sqrt( 9^2+12^2) = sqrt( 81+144) = sqrt(225) = 15! Voila :)
B is the correct answer, that is y = 48/x because as we know y=4 and x=12
48/x = 48/12 = 4 =y
