Answer:

C. ?????

Explanation:

Given code:

void unknown(int n)

{

if(n>0)

unkown(n-1);

System.out.print("?");  

}

Calling code: unknown(4)

This is a recursive invocation of unknown function and causes ? to be printed 5 times once each for following values of n.

  • unknown invocation with n=4
  • unknown invocation with n=3
  • unknown invocation with n=2
  • unknown invocation with n=1
  • unknown invocation with n=0

When n becomes 0, termination condition is reached and the function returns.

So the output is ?????

Integral 3t+ 1 / (t + 1)^2​
Verizon [17]

Answer:

3ln|t+1|+\frac{2}{t+1} +C

Explanation:

We'll be using u-substitution for this problem.

Let

u=t+1\\du=dt

Substitute

\int\limits {\frac{3u-2}{u^2}} \, du

Split the fraction

\int\limits {\frac{3u}{u^2} } \, du -\int\limits {\frac{2}{u^2} } \, du

Move the constants out

3\int\limits {\frac{u}{u^2}du -2\int\limits {u^{-2}} \, du

Simplify

3\int\limits {\frac{1}{u}du -2\int\limits {u^{-2}} \, du

Integrate

3ln|u|+\frac{2}{u} +C

Substitute

3ln|t+1|+\frac{2}{t+1} +C

If you need to multiply 50 and 8 and divide by 2, what would you type on the numerlc keypad?
nata0808 [166]

Answer:

50*8/2

The asterisk is the multiplication sign and the parenthesis is the division.

I've never used an apostrophe for a multiplication sign before, but I'm guessing multiplication is what it stands for.
