Answer:
sqroot(9) - 7 = -4
sqroot(10) - 7 = -3.838
sqroot(11) - 7 = -3.683
sqroot(12) - 7 = -3.536
It isd not equal to -4 but pretty close so I am thinking that B is the right choice.
Answer is B
Step-by-step explanation:
2 radical 13
2.82 seconds (3 sf)
s = ut + 0.5at²
6 = -95(sin25)t + 0.5(32)t²
16t² - 40.14873487t - 6 = 0
t = 2.818501699, -0.1419193751
t is time so can't be negative.
Therefore, t = 2.82s (3 sf)
132.4
