It's the third one. It is the correct option.
Root are also known as what x is equal to. So, to find x you would need to set (x-4)=0 and (x+7)=0
X=4. X=-7
The movement of the minute hand is circular.
Tangence speed is V=2Rπ/T= 2*7*3.14/3600 inches/sec=0.012211 inches/sec
The path (distance) that minute hand past is D=V*t = 0.012211 * 5 min= 0.012211 * 300sec=>
D=3.663≈3.66 inches
Good luck!!!
There are 4 quarts in a gallon.
In two gallons would be 8 quarts.
2 gallons - 5 quarts = 8 quarts - 5 quarts = 3 quarts.
Note: 3 quarts is 3/4 or .75 of a gallon.
