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:
Then the multiplication is:
h(x) = f(x)g(x) = 80x(x + 7) = 80x² + 560x.

Answer:
y= 3x + 7 Step-by-step explanation:
y= -1/3x+3 (so, gradient of this line is -1/3).
formula: gradient of line one x gradient of line two= -1 (applies for 2 perpendicular lines only).
So, m1 x -1/3= -1
m1= (
)
m1= 3 (gradient of perp line)
y=mx+c
4= 3 x -1 + c
7=c
therefore, y=3x+7 (eqn of the line perp to y=-1/3x+3)
4x + 12 = 48
4x = 48 -12
4x = 36
x= 36 / 4
x= 9
Each ticket is $9.
Add 720 degrees (which represents two full revolutions around the center) to -800. Result: -80 degrees. This angle is in Quadrant IV.
Subtracting 80 from 360 will give you a positive angle co-terminal with -800 deg. 360 - 80 = ?
