Answer:
the height is 9
Step-by-step explanation:
To find the answer, we first need to understand the formula to find the volume of a cone:
Volume = 1/3 x base area x height
In this case, we can put the given information into the formula.
The base area of the cone: pi(radius)^2 = pi(3)^2 = 9pi
We can then find the height:
27pi = 1/3 x 9pi x height
27pi/9pi = 1/3 x height
3 = 1/3 x height
height = 9
Therefore, the height is 9cm.

Answer:
x-2i
Step-by-step explanation:
Complex roots come in pairs, called complex conjugates
If you have a root a+bi, the other root is a-bi
Since you have one root x+2i, the other root is x-2i
Answer:
Step-by-step explanation:
|8| = 8, and |-7| = 7. Thus, we have 8 + 7, or 15.

Answer:
41.04 g/L
Step-by-step explanation:
The relationship is modeled by the following function:
S(t) = 500*e^(-0.25*t)
where t is time elapsed after the dilution begins (in hours) and S(t) the concentration of salt in the tank (in g/L)
Replacing with t = 10
S(t) = 500*e^(-0.25*10)
S(t) = 41.04 g/L
