A weight is suspended from a spring and allowed to hang at its rest position. It is then pulled down 2 in, released, and allowed
to oscillate up and down. Its location (in inches) relative to its rest position is given by the function f(t)=2sin(2.5t - pi/2), where t is the time in seconds. How much time will it take for the weight to move through one complete cycle of motion? A.) 2.5 seconds B.) 3.1 seconds C.) 3.8 seconds D.) 5.0 seconds
An official playing field (including end zones) for the Indoor Football League has a length 29 yd longer than its width. The perimeter of the rectangular field is 158 yd. Find the length and width of the field
4 pennies = $0.04. 22 coins minus the 4 pennies = 18. So, 18 nickels is equal to $0.90. Because she has at most 22 coins and they're worth at least $0.78 then $0.94 would make since.
