In this question, f : R → R is a differentiable function. We will use linear algebra try to find a good linear approximation to f near a point x = a. Our linear approximation will be of the form y = c + mx. Use the values of f at the point a and the nearby point a h to find a good approximation. (You will need to set up a linear system involving c, m, a, h, f(a), f(a+ h), where c and m are the variables. You should also be able to solve this linear system exactly for the vector.

Step-by-step explanation:

Given that:

Our linear approximation will be of the form y = c + mx. Use the values of f at the point a and the nearby point a h to find a good approximation. (You will need to set up a linear system involving c, m,a, h, f(a), f(a+ h), where c and m are the variables. You should also be able to solve this linear system exactly for the vector.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

10+4√2 is the answer. i dont have the time to explain.
