F( g( f(x) ) ) = f( g( 2x+1 ) )
= f( 2x+1 -3 )
= f( 2x-2 )
= 2(2x-2) +1
= 4x -4 + 1
= 4x -3
Answer:
B .62.5 m
Step-by-step explanation:
convert Kmh-1 in to ms-1
30 Kmh-1 = (30×1000) ÷3600 = 8.3ms-1
60 Kmh-1 = (60×1000) ÷3600 = 16.6 ms-1
acceleration = (16.6 - 8.3) ÷ 5 = 1.66 ms-2
V^2 = U^2 +2aS
(16.6)^2 = (8.3)^2 + 2×1.66 ×S
S = 62.5 m
Answer:
s = 2
