A reduction of 126000 visitors in 3 months is an average rate of change of:
-126000 / 3
= -42000 visitors / month.
The answer is negative because it is a reduction.
2.
50ft in 28sec downward
= – (50 / 28) ft/sec
= -1.78 ft/sec
= -1.8 ft/sec. to nearest tenth,
3.
The balance changes by:
$100 – $75 + $85 – $150 in a month
= -$40 / month
= -$(40 * 12) / year
= -$(40*12 / 365.25) /day
= -$1.314 per day
= -$1.31 per day to nearest cent.
