Answer:
Step-by-step explanation:
a). 'Per ml' cost of the small size =
=
= $0.018
'Per ml' cost of the medium size =
= $0.0199
'Per ml' cost of the large size =
= $0.01695
Therefore, expression to compare per ml cost of three containers will be,
$0.0199 > $0.018 > $0.01695
b). Least expensive way to buy the cleaner is to choose the container with least per ml cost.
Cost of 1500 ml cleaner = Cost of 1000 ml cleaner + Cost of 500 ml of cleaner
= Cost of 1000 ml cleaner container + Cost of 'n' containers of 250 ml container
Total cost of 1500 ml = $16.95 + $4.50n
= 16.95 + 2(4.5) [For n = 2]
= $25.95
c). Most expensive way to purchase 1500 ml cleaner is to choose the most expensive cleaners
Cost of 1500 ml cleaner = Cost of 'n' containers of medium size containers
= 9.95(n)
= 9.95(3)
= $29.85
1.5
base x height x 0.5
Pythagorean theorem: c^2 - a^2 = b^2
b = square root of (2.5)^2 - (1.5)^2
= 2
b = height
area = 0.5 x 1.5 x 2 = 1.5
8
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8
