"The quantity of price measured in dollars depends on the quantity of time measured in minutes" is an example that best defines the two quantities that are measured to find the call rate of a cell phone company.
Answer=4
8*16=128
your number is 8
therefore half your number is 4
8/2=4
268.08
V=4/3(pi)r(cubed)
Plug and chug —> the volume of this sphere is about(squiggly equality sign) 268.08 feet
The equation of the tangent line is 
To find the tangent to the hyperbola
at (x₀, y₀), we differentiate the equation implicitly to find the equation of the tangent at (x₀, y₀).
So, 
So, at (x₀, y₀)

So, the equation of the tangent line is gotten from the standard equation of a line in point-slope form
So, 
So, the equation of the tangent line is
