Use an appropriate taylor polynomial about 0 and the lagrange remainder formula to approximate sin(4/7) with an error less than 0.0001. sin(4/7) ≈ ? (give your answer to 6 decimal places)what is the smallest value of n for which the approximation above is guaranteed to have an error less than 0.0001? (be careful. think about the actual terms used in the series as well as the remainder.)n = ?

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
