a) 32/8= 4
32/20= 1.6
84/30= 2.8
100/40= 2.5
4+1.6+2.8+2.5= 10.9
10.9/4=2.725 so on average the bassett travels 2.725 yards per second
b) the bassett stops moving for 12 seconds, I know this because between seconds 8 and 20, there is no rise in yards
c) 20 to 30 seconds because it has the steepest increase in yards, with the least time passed.
B, the number of females is 40, while the number of males is 80. 40x2=80

2
Answer:
x = √2 = 1.414
Step-by-step explanation:
5x-(x+2)^2=x^2-8+x
since (x+2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4
so
5x - (x^2 + 4x + 4) = x^2 + x - 8
-x^2 + x - 4 = x^2 + x - 8
x^2 + x^2 + x - x = -4 + 8
2x^2 = 4
x^2 = 2
x = √2 = 1.414
Answer:
all real numbers such as 0<y<40
Step-by-step explanation:
as the tub is draining water, it will never exceed original amount of 40. the lowest amount of water you can have is 0, never below 0
