What is the f(n) runtime of the following pseudocode: sum = 0 for A = N/2 downto 1 for B = 1 to 4N increment sum by B
nikitadnepr [17]

Answer:

f(N) = 2+ N/2 + 6N² units of time.

Step-by-step explanation:

Assigning 0 to the variable sum takes one unit of time.

Each time you increment sum by B, you need to call the value of sum, sum it to B and assign it to sum, which takes three units of time in total. You are repeating this process for each value of B which ranges from 1 to 4n and for each value of A which ranges from 1 to n/2. Opening the FOR takes also another unit of time, so, as a result, we have

f(N) 1 + 1 (open the FOR in A)+ N/2*(1 (open the FOR in B) + 4N*3) = 2+ N/2 + 6N² units of time. It has order complexity O(N²).

Solve for y in terms of x.
krek1111 [17]

<u>Answer:</u>

y=\frac{3}{2} x+6

<u>Step-by-step explanation:</u>

We are given the following equation and we are supposed to solve y in terms of x. It simpler terms, it means that we have to make y the subject of the equation while x being used in it as it is:

\frac{2}{3} y-4=x

Taking the constant 4 to the side where x is to get:

\frac{2}{3} y=x+4

Multiplying the denominator 3 to the other side of the equation to get:

2y=3x+12

Isolating y to make it the subject:

y=\frac{3}{2} x+\frac{12}{2}\\ \\y=\frac{3}{2} x+6
