Answer:



Step-by-step explanation:
Given
See attachment
Solving (a): g(-1)
We make use of:

Because:
is true for x =-1
Hence:

Solving (b): g(0.75)
We make use of:

Because:
is true for x =0.75
Hence:

Solving (b): g(1)
We make use of:

Because:
is true for x =1
Hence:

Work shown above! Answer to both is A

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
You find the lowest common denominator of both fractions, which in this case is 24.
1/6 is equivalent to 4/24 and 1/8 is equivalent to 3/24.
4/24 + 3/24 = 7/24
