(a) 8t - 4t* + 10 dt = +C. (b) 3/4 + 2,/udu = +C. (c) dx = 4x5 +C.(5 points) Given that the graph of f passes through the point (1, -5) and that the slope of its tangent line at (x, f(x)) is 2x + 1, find f (-10). f(-10) = 78(5 points) Evaluate the indefinite integral. (use C for the constant of integration.) dx = (x4 + 9)4(5 points) Evaluate the indefinite integrals using Substitution. (use C for the constant of integration.) a) sin*(x) cos(x) dx = b) - sin(x)(cos(x))' dx =
