Step-by-step explanation:
Multiple y by 5
$9.99+$0.25x
X stands for the number of songs the person got which would come around 415 songs
This is an obtuse triangle.
Acute triangles have angles of less than 90º.
Right triangles have an angle equal to 90º.
Obtuse triangles an angle more than 90º.
The maximum or minimum point can be obtained by obtaining an expression of the slope of the curve and equating this to zero. The slope of the curve can be obtained by dg/dx
therefore
dg/dx = 200x - 1100
equating this equation to zero
dg/dx = 0 = 200x - 1100
therefore x = 5.5
there g(x) = 100* (5.5)^2 - 1100*5.5 = -3025
