Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
Answer:
68cm^2
Step-by-step explanation:
<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>
Area of a trapezium= 1/2(sum of parallel sides)×height
Area of the trapezium= 1/2(5+3)×17
Area of the trapezium= 1/2(8)×17
Area of the trapezium=4×17= 68cm^2
The value of his investment at the third year is
F (3)=300×(1.02)^(3)=318.36
The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22
The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year
It is 860.4 because if you multiply it in the calculator you will get the answer. So you put in 71.1 times 12 and you get 860.4.
