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

Answer:
$12
Step-by-step explanation:
Given data
Radius= 2in
cost = $4
New jaw breaker radius= 6in
cost=???
If 2 in jaw breaker cost $4
6in jaw breaker will cost x
cross multiply
6*4= 2*x
24= 2x
x= 24/2
x= $12
Hence the 6 in jawbreaker will cost $12
