In the 2012 olympics, usain bolt ran the 100m dash in 9.63 seconds. jim hines won the 1968 olympic gold with a time of 9.95 seconds. a. bolt’s time was % faster than hines’. b. hine’ time was % slower than bolt’s. c. hine’ time was % of bolt’s.

a. bolt’s time was 32% faster than hines’.

b. hine’ time was 32% slower than bolt’s.

c. hine’ time was 1.03% of bolt’s.

step-by-step explanation:

given bolt's time was 9.63 seconds

jim time was 9.95 seconds

difference in time between the two runners

9.95-9.63=0.32 seconds

express it as a percentage

0.32×100=32%

jim time= 9.95

bolt's time=9.63

jim's time as a percentage of bolt's time

9.95/9.63 ×100=1.03%

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
