Answer:
Step-by-step explanation:
-8s-28>4
-8s-28+28>4+28
-8s>32 we divide by 8
-s>4 we multiply by -1 and we will change the sign because of this
s<-4
Answer:
B
Step-by-step explanation:
IQR is the higher qurtile subtracted by the lower qurtile so higher is 40 and lower is 20 so 14
Hope this helps have a great day:)
(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
Answer:
180 fb*lb
45 ft*lb
Step-by-step explanation:
We have that the work is equal to:
W = F * d
but when the force is constant and in this case, it is changing.
therefore it would be:

Where a = 0 and b = 30.
F (x) = 0.4 * x
Therefore, we replace and we would be left with:

We integrate and we have:
W = 0.4 / 2 * x ^ 2
W = 0.2 * (x ^ 2) from 0 to 30, we replace:
W = 0.2 * (30 ^ 2) - 0.2 * (0 ^ 2)
W = 180 ft * lb
Now in the second part it is the same, but the integral would be from 0 to 15.
we replace:
W = 0.2 * (15 ^ 2) - 0.2 * (0 ^ 2)
W = 45 ft * lb
