To find area you multiply length times width in this case that would be 130x110= 14,300 then divide 14,300 by 4,840 because one acre is equal to 4,840 yards. Answer: 2.95 Acres
The number is -2
-2 + 4 = 2
2 is 2 less than 4
average rate of change is the slope (of the line) between the two coordinates
f(t) = -16t² + 48t + 100
f(3) = -16(3)² + 48(3) + 100 = -144 + 144 + 100 = 100 (3, 100)
f(5) = -16(5)² + 48(5) + 100 = -400 + 240 + 100 = -60 (5, -60)
m = = = = -80
Answer: -80 ft/sec
