Answer: 9
Step-by-step explanation: -(-3)=3^2=9
Answer: 25/36
Step-by-step explanation:
Multiply:
2/3 * 10/24 = 20/72 = 5/18
-3 1/8 * -4/5 = 5/2
5/18 * 5/2 = 25/36
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:
-3,7,17,27,37,47,57,67,77,87,97,107
Step-by-step explanation:
You add 10 to -3 which gives you 7. You continue adding. This sequence goes on forever. You just keep adding 10.
I hope this helps!
