Answer: 
The question is incomplete as some details are missing; Here is the complete question; If vector u = 3i and v = 4i + 4j, Find the measure of the angle θ between u and v. Express the answer in radians rounded to two decimal places, if it is not possible to express it exactly.
The measure of the angle θ between u and v = 0.785radians

Answer:
None of the above, f(5) + g(-3) = 19.
Step-by-step explanation:
Given f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3). Assume that is supposed to be f(5) + g(-3).
f(5) + g(-3) = 2×5 + 4 + (-3)^2 - 4
 = 10 + 4 - 4 + (-1)^2(3)^2
 = 19
