1. Suppose that algorithm A takes 1000n3 steps and algorithm B takes 2n steps for a problem of size n. For what size of problem is algorithm A faster than B (meaning algorithm A has fewer steps than B)? In your answer describe not only what the answer is but how you arrived at the answer. 2. Give the upper bound (big O notation) that you can for the following code fragment, as a function of the initial value of n. for(int i = 0; i < n; i++) { for(int j = 0; j < i; j++){ //do swap stuff, constant time } } Do you think that the lower bound is likely to be the same as the answer you gave for the upper bound? In your response state why or why not.

When developing a stakeholder matrix, the portfolio manager must look at the portfolio governance in order to complete the stakeholder analysis. in your own words, what is the role, interest and expectations of the governance?

Ap practice - performance task response the ap create performance task asks you to write about an abstraction that you developed and wrote into your code. most of the time that means identifying a function or procedure you wrote to "manage complexity" in your program. here is the actual prompt from the create performance task: 2d. capture and paste a program code segment that contains an abstraction you developed individually on your own (marked with a rectangle). this abstraction must integrate mathematical and logical concepts. explain how your abstraction manage the complexity of your program. (must not exceed 200 words) below is a segment of code from an "under the sea" program with a rectangle drawn around a portion of the code identifying an abstraction. imagine that you wrote this and are composing an ap response about how this abstraction manages complexity. (note: ignore the requirement that the abstraction integrate "mathematical and logical concepts" for this practice response. just write about managing complexity). explain how the abstraction marked with the rectangle in the code above manage complexity of this program. write your response here submit

Technician a says that if a valve is open when a piston rises to the very top of a cylinder, the piston may actually strike the valve head and cause serious engine damage. technician b says if the camshaft is located in the engine block, then the engine is called an overhead valve engine, ohv engine, or an in-block camshaft. who is right? a. b only b. both a and b c. a only d. neither a nor b
