1· (1 point each) Given the array defined below, evaluate each of the expressions and write their value in the space provided. If the expression will cause an error, write "ERROR" in the space instead. Note that each expression is independent. They do not build on each other, so each should be applied to the original array as shown here: int [ ] numbers = {7, 15, 13, 10): a. numbers[O] b. numbers[2] c. numbers[1 + 2] d. numbers[4] e....

1. (9 points, 3 points each) Using the Boolean identities, simplify the following expressions: a. (x7)Zi)(2+ y) b. 7(xyz) + y(ż + (7 +z)) C. (xz + ✓x) + y(x+y)(7+ y)
Evaluate the following expressions: Note: You are not allowed to use decimals in any answer. a. log2 (52) = 0 (exact value) b. If log)(x) = 4 and log (y) = -10, then log, (xy) = (exact value) c. log3 (12) = (Express in terms of 'log' or 'In") d. cos $(134) =(exact value) e. If f(-2) = 10, then f-'(10) = f. If the polynomial p(x) is divided by (x + 8), the remainder is 15. Therefore p(-8) =
