Nikolas calculated the volume of the prism. His work is shown below. A triangular prism. The triangular base has a base of 5.8 f
eet and height of 6.2 feet. The height of the prism is 9.2 feet. Nikolas’s Work: Area of base = B = one-half b h = one-half (5.8) (6.2) = 17.98 feet squared. Volume = B h = (17.98) (9.2) = 165.416 feet cubed. Where, if any, did Nikolas first make a mistake in his work? A. Nikolas used the wrong measurements when finding the area of the base. B. Nikolas used the wrong formula for the volume of the prism. C. Nikolas made a computational error. D. Nikolas did not make a mistake.

hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t = and t = -
However, as time cannot rewind, we will keep only positive solution
So t =
in seconds it will be : 3.3 seconds
