5.

Which value of x, with −4 ≤ x ≤ 4, corresponds to the global (absolute) maximum of the functions f(x) = x 2 (3x 2 − 4x − 36) + c, where c is some given real number?

(a) −2 (b) 2 (c) 3 (d) 0 (e) None of the above.

14. Find f(x) by solving the initial value problem. f 0 (x) = e x − 2x; f (0) = 2

(a) f (x) = e x − x 2 (b) f (x) = e x − x 2 + 1 (c) f (x) = e x − x 2 + 2 (d) f (x) = e x − x 2 + C (e) None of the above.

18. Let f(x, y) = 1 + x + y + x 2 + axy + y 2 be a function of two variables. Suppose it is always true that ∂f /∂x = ∂f /∂y . What is the value of a?

(a) Any value of a is possible since mixed partial derivatives are equal. (b) 0 (c) 2 (d) 1 (e) There is no such value of a since the partial derivatives must be different.

Please provide the correct solution for each problem for a thumbs up. thank you!

Fundamental Theorem of Line Integrals Consider the line integral: ∮_C▒〈6xy+6x, 3x^2-3 cos⁡(y) 〉 ∙dr ⃗ where C is the line segment from the origin to (4, 5). Evaluate this integral by rewriting the integral as a standard single variable integral of the parameter t. Without finding a potential function show that the integrand is a gradient field. Find a potential function for the vector field. Use the Fundamental Theorem of Line Integrals to evaluate this integral.

Solve the following constant coefficient linear differential equations using Laplace Transform (LT), Partial Fraction Expansion (PFE), and Inverse Laplace Transform (ILT). You must check answers in the t-domain using the initial conditions.

Note: Complex conjugate roots

y ̈ (t) + 6 ̇y (t) + 13y (t) = 2

use the initial conditions
y(0) = 3, ̇y(0) = 2.
