Answer:
1
Step-by-step explanation:
First we have to factor:
-5 * -5 equals 25 and adds up to -10.
(x - 5)(x - 5)
The only answer is positive 5, so there is only 1 solution.
That would be equal to the slope of the line
slope = rise / run = 100-10 / 30 = 90/30 = 3 Answer
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
A) Both walked 3.5 hours.
B) Hannah walked 3.5 x 3 = 10.5 miles.
For Hannah you multiplied her rate by the time to get total distance.
Penelope walked 7 miles, the black dot on the graph is at the 7 miles on the distance.
C) Hannah walked a faster rate, because she walked further in the same amount of time.
