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

The standard form of a hyperbola is <span><span><span>x2/</span><span>a2 </span></span>− y<span><span>2/ </span><span>b2 = 1
the tangent line is the first derivative of the function</span></span></span><span>y′ = <span>b^2x/ a^2 y

Please help!
Schach [20]

Answer:

A) Yes, for each increase of 25 employees there is an increase of 150 products.

B) y = 6x + 10

C) the slope indicates the increase that will occur in the y-value for each unitary increase in the x-value, and the y-intercept indicates the inicial value of y (when x = 0)

Step-by-step explanation:

A)

Yes, there is a linear correlation, because a linear increase in the number of employees causes a linear increase in the number of products. For each increase of 25 employees there is an increase of 150 products.

B)

We can use two pair of points to write a linear equation in the model:

y = ax + b

Using x = 0 and y = 10, we have:

10 = a * 0 + b -> b = 10

Using x = 25 and y = 160, we have:

160 = a * 25 + 10

25a = 150 -> a = 6

So the equation is:

y = 6x + 10

C)

the slope indicates the increase that will occur in the y-value (number of products) for each unitary increase in the x-value (number of employees), and the y-intercept indicates the inicial value of y (when x = 0, that is, no employees)
