Answer:
(-∞,0)∪(0,∞)
Step-by-step explanation:
The domain of a function is wherever the y values exist. The only time the y values dont exist in this function is when the denominator is zero. So the denominator does not exist at x=0, because that is when 4x = 0.
Answer: The answer should be 38.
I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.
Step-by-step explanation:
2.3 (14+6) -2 to the power of three
2.3 (20) -2 to the power of three
2.3 (20) -8
46-8
38
I really hoped this helped and if I got it wrong with the t just reply to me c:
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
