**1. Homework Statement**

A friend gave me these problems to solve, believing they were calculus problems, which I did study over 10 years ago. They seem more related to economics, which I did not study.

**2. Homework Equations**

**3. The Attempt at a Solution**

The only attempt I made was for Q3.

H1=t

H2=10-t

B=1

Y= t^2 + (10-t)^2 + t(10-t)

= t^2 + 100 - 20t + t^2 + 10t - t^2

= 100 - 10t + t^2

But do not know if this means it exhibit skill-complementarities or not.

Any help is appreciated, and thanks in advance.
