Answer:
A
Step-by-step explanation:
how long is the ball in the air ?
that is the same as asking : after how many seconds will the ball hit the ground (= reach the height of 0) ?
so, that means we need to find the zero solution of h(t).
at what t is h(t) = 0 ?
when at least one of the factors is 0 :
2(-2 - 4t)(2t - 5)
we have 3 factors
2 : can never be 0.
(-2 -4t) : can only be 0 for negative t, which does not make sense in our scenario (we cannot go back in time, only forward).
(2t - 5) : is 0 when 2t = 5 or t = 2.5
so, A is the right answer.
FYI : the starting height (on the hill) is given by t = 0 :
2(-2 - 0)(0 - 5) = 2×-2×-5 = 20 ft
Hola , la cantidad de las pelotas blancas es 1/4 es otras palabras 25 por ciento ya que 1 divido entre 4 es .25 , o sea hay 6 pelotas blancas ya que 25 por ciento mas 25 por ciento es 50 por ciento la mitad , entonces tienes que agregar 6 bolas.

Answer:
13/6 or 2 1/6
Step-by-step explanation:
6 1/2 = 13/2 (Improper Fraction)
1/3 = 2/6 (1/3 is just simplified)
1/3 x 1 + 1 + 4 + 6 + 1 = Answer
(13/2 x 1/3 = 13/6)
