In the end, Wally makes $2 (profit)
-$5,+$6,-$7,+$8
It’s not a function because there are two y values for the same x value at x=2
Answer:
{-6, -5, -4, -3, -2, -1}.
Step-by-step explanation:
The set contains the integer -6 ( because of the ≤ ) but not 0 because of the < 0.
Answer:
The price where the manufacture sells the maximum number of toys is $20
Step-by-step explanation:
The given equation for that represents the number of toys the manufacturer can sell is given as follows;
T = -4·p² + 160·p - 305
Where;
p = The price of the toys in dollars
At the point where the manufacture sells the maxim number of toys on the graph of the equation T = -4·p² + 160·p - 305, which is the top of the graph, the slope = 0
Therefore, at the maximum point;
The slope = 0 = dT/dp = d(-4·p² + 160·p - 305)/dp = -8·p + 160
∴ -8·p + 160 = 0
160 = 8·p
8·p = 160
p = 160/8 = 20
The price where the manufacture sells the maximum number of toys is = p = 20 dollars
