The number of rows in an auditorium can be represented by the function f(x) = 80x. the number of seats in each row can be repres
Dominik [7]

Applying multiplication of functions, the total number of seats in the auditorium is given by:

h(x) = 80x² + 560x.

<h3>How polynomial functions are multiplied?</h3>

They are multiplied applying the distributive property, that is, all the terms are multiplied and then the common terms are added.

In this problem, the functions are given as follows:

  • f(x) = 80x.
  • g(x) = x + 7.

Then the multiplication is:

h(x) = f(x)g(x) = 80x(x + 7) = 80x² + 560x.

Wewaii [24]

Answer:

Step-by-step explanation:

sinD = opposite/hypotenuse = 12/15 = 4/5

cosD = adjacent/ hypotenuse = 9/15 = 3/5
