Well, for a line with a slope of 3/4, any other parallel line to it, will also have the same slope of 3/4
so if the line through (2, -1) is parallel to it, it has a slope of 3/4 as well
We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />
Use the formula (new price-old price) / old price
32-40=-8
-8/40=-20%
the percent difference is 20%
the negative means it was a markdown
Answer:
C : 20
good luck, hope this helped!
(2.5, 2.5) and (2, 0)
But you knew that already
sorry
