Answer:
From 2004 onwards, fewer than 38.1% of U.S. voters use punch cards or lever machines
Step-by-step explanation:
The percentage of U.S. voters who use punch cards or lever machines in national elections, in x years after 1994, is given by the following equation:
In which years will fewer than 38.1% of U.S. voters use punch cards or lever machines?
In x years after 1994 onwards.
x is found when P(x) = 38.1.
So
From 2004 onwards, fewer than 38.1% of U.S. voters use punch cards or lever machines
Revenue=quantity x price= (-2p+1000) (p)= -2p^2+1000p
The maximum revenue will occur when the first derivative is zero so when 2(-2p)+1000=0;p=250
Which generates 125,000 in revenue
Try prices of 245 and 255 and you will see they both are less than 250 thereby proving the max revenue is 250
Answer:
A) Neither
Step-by-step explanation:
If two lines have same slope then they are parallel lines
If slope of line1* slope of line 2 = -1
The the two lines are perpendicular
In this question slope of line = 2\7
Slope of line 2 = 7\2
