Need help with question 2 a) and b).
thank you

Question 2 These questions are related to the applications of Engineering Mathematics. Solve the following question, giving the answers as exact logarithms where appropriate. 4 cosh(t) – 1 = sin inh(e) (b) Sarah invests a total of RM 10,000 in three accounts, one paying 5% interest, another paying 8% interest, and the third paying 9% interest. The annual interest earned on the three investments last year was RM 770. The amount invested at 9% was twice the amount invested at 5%. By using the Gaussian elimination method, determine the value of investment for each rate.
