Find a power series for the function, centered at c. f(x) = 1 9 − x , c = 4 f(x) = [infinity] n = 0 Incorrect: Your answer is incorrect. Determine the interval of convergence. (Enter your answer using interval notation.)

Looks like the given function is

Recall that for |x| < 1, we have

We want the series to be centered around , so first we rearrange f(x) :

Then

which converges for |(x - 4)/5| < 1, or -1 < x < 9.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
