F(x) = x²-4x-5, quadratic function,
Domain (the values if x) is all real numbers.
To find range we should draw a graph or to write an equation in vertex form.
f(x) = x²-4x+4-4-5
f(x) = (x-2)²-9
Point (-2,-9) is the vertex of the parabola, and it is a minimum because a parabola has positive sign in front of x², so it is looking up. Minimum value of y =-9
Range(the values of y) is [-9, ∞)
Tan(E) = 6/8 =3/4
tan(E) (opposite side)/(adjacent side)
80 student tickets and 30 adult tickets must be sold to reach a $700 raise.
Since the drama club is selling tickets to their play to raise money for the show's expenses, and each student ticket sells for $ 5 and each adult ticket sells for $ 10, and the auditorium can hold a maximum of 110 people and the drama club must make a minimum of $ 700 from ticket sales to cover the show's costs, to determine one possible solution the following calculation must be performed:
- 110 x 5 + 0 x 10 = 550
- (700 - 550) / (10 - 5) = 150/5 = 30
- 80 x 5 + 30 x 10 = 400 + 300 = 700
Therefore, 80 student tickets and 30 adult tickets must be sold to reach a $700 raise.
