Answer:
a) $86.11
b) $467.33
Step-by-step explanation:
no. of gallons saved 'n' per year
n = (10000/33) - (10000/36)
n = 2500/99
Amount saved = 3.41×n = 3.41×2500/99
= $86.11
b) over 5 years:
86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )
= 86.11(5.427157431)
= $467.33
Answer: 
<u>Step-by-step explanation:</u>
The vertex form of a parabola is: y = a(x - h)² + k where
- (h, k) is the vertex
NOTE: p is the distance from the vertex to the focus
The vertex (h, k) is (2, -3)

Insert those values into the vertex formula to get:

Answer:
B. 64 cubic meters
Step-by-step explanation:
The first rectangle has the dimensions 7 x 2 x 4. 2 x 4 is 8, and 8 x 7 is 56. The square has the dimensions 2 x 2 x 2, which is 8. 56 + 8 is 64, so the answer is 64.
Answer:
m =-1.25
Step-by-step explanation:
5.2m + 5 = 2.9m – 3 – 4.1m
Combine like terms
5.2m + 5 = -1.2m – 3
Add 1.2m to each side
5.2m +1.2m +5 = -1.2m +1.2m -3
6.4m +5 = -3
Subtract 5 from each side
6.4m +5-5 = -3-5
6.4m = -8
Divide each side
6.4m/6.4 = -8/6.4
m =-1.25
