Answer: option A. 9.2 gal/year
Justification:
The average rate of change from 1960 to 1970 is the change on the variable gallons consumed per passenger car divided by the period
average rate of change = Δg / Δt
Δg = 760 gallons - 668 gallons
Δt = 1970 year - 1960 year
760 gal - 668 gal 92 gal
average rate of change = -------------------------------- = ---------- = 9.2 gal / year
1970 year - 1960 year 10 year
Answer: 9.2 gal / year
As you see for this specific period, 1960 to 1970, the vehicles increased their consumption of gas per passenge, meaning that they became less efficient.
Answer:
20) 8 years
21) Tori could paint the room alone for 3 hours, Sydney could paint the room alone for 5 hours.
Step-by-step explanation:
A = P ( 1 + r/n ) ^ nt.
8000 = 5000 ( 1 + 6%/4) ^ 4t
8000 = 5000 ( 1 + 0.06/4) ^4t
8000 = 5000 ( 1 + 0.015 ) ^ 4t
8000 = 5000 ( 1.015 ) ^ 4t
8000 / 5000 = ( 4.06 / 4 ) ^ 4t
8/5 = ( 203/200 ) ^ 4t
b = aᶜ ⇔ logₐb = c
