Answer:
   1.63 cm (across the centerline from release)
Step-by-step explanation:
If we assume time starts counting when we release the weight from its fully-extended downward position, then the position at 1.15 seconds can be found from ...
   h(t) = -7cos(2πt/4)
   h(1.15) = -7cos(π·1.15/2) = -7(-0.233445) ≈ 1.63412 . . . cm
That is, 1.15 seconds after the weight is released from below the resting position, it will be 1.63 cm above the resting position.
__
If it is released from <em>above</em> the resting position, it will be 1.63 cm <em>below</em> the resting position at t=1.15 seconds.

Answer: 33.33%
Step-by-step explanation:
Number of White sneakers = 8
Number of Black sneakers = 10
Number of Blue sneakers = 10
The percentage of Oscar's sneakers that are black will be:
= Number of black sneakers / Total sneakers × 100
= 10/30 × 100
= 33.33%
