Сorrect statements:
1. EF is the longest side
2. DF = 6 cm (in a 30-60-90 triangle the side opposite the 30 degree angle is half the length of the hypotenuse. )
3. <span>By the Pythagorean theorem:
DE = </span>√(12²-6²) = √(144-36) = √108 = 6√3
DE = 6√3 cm
The initial velocity of the fish is the same as that of the pelican and it is -0.50 m/s. The distance traveled by the object is given by the equation,
d = (V1)t + 0.5at²
where t is equal to 2.50s and the acceleration due to gravity, a, is 9.80 m/s². Substituting,
d = (-0.50 m/s)(2.5 s) + 0.5(9.8 m/s²)(2.50 s)²
d = 30.625 m
Thus, the answer is letter C.
