Round your answers to two digits. Suppose you have been told that a differentiable function T of two variables satisfies T(-2, 3) = 4, T;(-2, 3) = 2, and T2(-2, 3) = 12. Find an approximate value for T(-1.97, 3.02): T(-1.97, 3.02) ~ The following equation implicitly defines a function t(r, s) = c: earst _ 976 84+5. Find the partial derivative of t with respect to s and express it as: at a . rtearst - b . 7693+5 as c . rsearst - d . p6 4 4 + 9 . est + k . The coefficient a is equal to X . The coefficient b is equal to X . The coefficient c is equal to X . The coefficient d is equal to X . The coefficient g is equal to X . The coefficient k is equal to X
