Answer:
-24
Step-by-step explanation:
You should leave $10.52 for waiter.
The total bill will be $67.33 including tax and tip.
Step-by-step explanation:
Given,
Bill before tax and tip = $52.60
Tip = 20% of pre tax amount
Amount of tip = 
Amount of tip = 
Amount of tip = $10.52
Sales tax = 8%
Amount of sales tax = 
Amount of sales tax = 0.08*52.60
Amount of sales tax = $4.208
Final bill = Bill + Tip + Sales tax
Final bill = 52.60 + 10.52 + 4.208 = $67.33
You should leave $10.52 for waiter.
The total bill will be $67.33 including tax and tip.

Answer: Angle 2= 82
Step-by-step explanation:
Area of the Figure = Area of Parallelogram + Area of Triangle
A = b*h + 1/2bh
A = 11*9 + 1/2*9*8
A = 99 + 36
A = 135 in²
In short, Your Answer would be: 135 in²

Answer:
<h3>
f(x) = -x² + 20x - 96</h3>
Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors
So we get:
f(x) = a(x - 8)(x - 12)
The parabola passes through point (13, -5) that means if x=13 then f(x)=-5
So:
-5 = a(13 - 8)(13 - 12)
-5 = a(5)(1)
-5 = 5a
a = -1 {<0 so parabola opens down}
Therefore:
f(x) = -(x - 8)(x - 12)
And expanding:
f(x) = -(x² - 12x - 8x + 96)
So the standard form equation of the parabola:
<u>f(x) = -x² + 20x - 96</u>
