wo sailboats are sailing away from an island. Sailboat A is sailing North at 7 miles per hour and sailboat B is sailing East at 4 miles per hour. How fast is the distance between two sailboats increasing when sailboat A is 6 miles from the island and sailboat B is 5 miles from the island? Show you work and include diagram?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

The triangle forms a right angle triangle.
we apply pythagorean theorem
we need to find out how fast the distance is increasing . d(d)/dt
Now take derivative with respect to d
