Answer: 9°
Step-by-step explanation:
(3w + 7)° + 90° + (7w - 7)° = 180°
=> 3w + 7 + 90 + 7w - 7 = 180
=> 10w + 90 = 180
=> 10w = 180 - 90 = 90
=> w = 90 / 10 = 9°
Answer:
t = 
Step-by-step explanation:
Given a parabola in standard form : ax² + bx + c : a ≠ 0
Then the axis of symmetry is
x = - 
h = - 16t² + 20t + 6 is in standard form
with a = - 16 and b = 20, hence
t = - 
= ← axis of symmetry
Revenue:
R ( x ) / x = 30 - 0.25 x
R ( x ) = 30 x - 0.25 x²
Profit:
P ( x ) = 30 x - 0.25 x² - 200
P ` ( x ) = 30 - 0.5 x
30 - 0.5 x = 0
0.5 x = 30
x = 60
P max = 30 · 60 - 0.25 · 3600 - 200 = $700
Answer:
I should sell 60 tickets to maximize the profit.
(w-2)^2 = 63
FOIL left hand side:
(w-2)^2 = w^2 - 4w + 4
So,
w^2 - 4w + 4 = 63
w^2 - 4w - 59 = 0
Then use quadratic equation to get values of w = 2 + 3*root(7) and w = 2 - 3*root(7).
