Ok.
The volume of a cone is the volume of a cylinder over 3.
The volume of a cone is:
This problem gives us the diameter, which is twice of the radius. So, we'll just half it.
Radius (me) = 4 cm.
Substitute our given values into the equation.
Multiply
Multiply
This would make 
the closest option.
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
we can arrange this properly to form a quadratic equation by grouping like terms.
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
Y≤ 3x-1. Why?
Note that y intercept = -1 , but note also that it can get all values
smaller than - 1 as per the grey area
Answer: Explanation below.
Step-by-step explanation:
First of all you need to know how to convert a logarithm into an exponential expression. The property is:
This is the same as: 
Example 1:
We are trying to find what to raise 9 to, in order to get a result of 9.
When you have same bases, you equal exponents.
Therefore; 
Example 2:
In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: 
which is 2*2*2*2*2
Rewriting this example we have;
Since we have the same base, we equal exponents.
Therefore; 
Example 3:
729 can have a base of 3 if expressed as: 
2
Because 5x2=10
So times the smaller box by 2 to equal the bigger box.
Hope this helps! :)
