Find an equation of the tangent line to the hyperbola: x^2/a^2 - y^2/b^2 = 1 at the point (x0,x1)

musickatia [10]

The standard form of a hyperbola is x2/a2 − y2/ b2 = 1
the tangent line is the first derivative of the functiony′ = b^2x/ a^2 y
hence the slope is m = b^2 x0 / a^2 x1

Therefore the equation of the tangent line isy−x1 = b^2 x0 / a^2 x1* (x−x0)

Part A:What percentage of the total students surveyed like both watching television and reading?

The total amount of student is 230
The amount of students that like to read and watch television is 80

As a fraction it is 80/230
Turn that to a percentage
It is:34.7826%

Part A=34.7826%

Part B:What is the probability that a student does not like watching television also does not like reading?

On the table it shows 20

So the probability is 20/230

Part B=20/230
