6.3 feet per 60 seconds so if you want feet per one second you need to divide 6.3 and 60 which is 0.105 ft per 1 sec.
Answer:
250 sq ft
Step-by-step explanation:
Since the shorter side is along the street and the setback is 10ft from each side, the house is 50 ft wide
and 100 -20 -30 = 50 ft long
50 x 50 = 250 sq ft
The derivative is -6sin(3x)
