Answer:
the answer would be 2 * 2 * y √2 * 5* 7 * y
Step-by-step explanation:
Im not sure what that means but i can try...
Im not sure the order to put them in but the positive line is
y>1/2x-1
And the negative line is
Y<=3x+1
(I couldn’t find a less than and equal to sign)
Step-by-step explanation:
Slope = -5/5 = -1
Answer:
The height of the pile is increasing at the rate of 
Step-by-step explanation:
Given that :
Gravel is being dumped from a conveyor belt at a rate of 20 ft³ /min
i.e 
we know that radius r is always twice the diameter d
i.e d = 2r
Given that :
the shape of a cone whose base diameter and height are always equal.
then d = h = 2r
h = 2r
r = h/2
The volume of a cone can be given by the formula:




Taking the differentiation of volume V with respect to time t; we have:


we know that:

So;we have:



The height of the pile is increasing at the rate of 
It is 4 because the diameter is twice longer than the radius!
