A. False. The domain (x-coordinates) starts at 0, not at 100.
b. True. The range (y-coordinates) does start at 100 and increases.
c. True. The graph moves up to the right showing an increase in y as x increases.
d. True. Point (40, 222.11) means that when x = 40 years, y = $222.11.
e. False. The initial point is at x = 0 when the account was opened. At x = 1, it is already 1 year after the account was opened.

the slope of perpendicular lines must be opposite and reciprocal
Answer:
7088 m²
Step-by-step explanation:
The area of the half-cylinder is half the area of a cylinder with the same dimensions. This half-cylinder has a radius of 0.3 m and a length of 0.8 m, so its area is ...
A = πr(r +l) = π(0.3 m)(0.3 m+0.8 m) = 0.33π m² ≈ 1.0362 m²
The area of the bottom part of the box is the sum of its lateral area and its base area.
lateral area = Ph = (2(0.6m +0.8m))(0.75 m) = 2.1 m²
base area = lw = (0.8 m)(0.6 m) = 0.48 m²
The total area is then ...
total area = half-cylinder area + lateral area + base area
= 1.0362 m² +2.1 m² +0.48 m²
= 3.6162 m²
__
The area for 1960 mailboxes will be 1960 times this area, or ...
area for week's production = 1960 × 3.6162 m² = 7087.752 m²
It will take about 7088 square meters of aluminum to make these mailboxes.
