Please see below.

#### Explanation:

As I understand such a modeling appears to have used polynomials of degree

As you may see **^3** is used for writing a cube and **^2** is used for writing a square. They will appear as (here given in bold letters)

**N=−0.028t^3+0.06t^2+0.1t+17** and

**U=−0.38t^2+1.5t+42**

Hashes are added so that they look like a mathematical function or formula. To write such a polynomial, you can have details at https://socratic.org/help/symbols

If you have to work out value of a function say for

#=−0.028xx125+0.06xx25+0.1xx5+17#

#=-3.5+1.5+0.5+17=15.5# and

#=−0.038xx25+1.5xx5+42#

#=-0.95+7.5+42=48.55#
