Answer:
Step-by-step explanation:
Rate = 10%
Time = 2 years
Initial CO2 = 280000 metric ton
1st year
10% × 280000
= 28000 metric ton.
2nd year
10% × (280000 - 28000)
= 25200 metric ton.
Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200
= 226800 metric ton of CO2.
X is any number smaller than 8, or X<8. A positive integer could be 7, 6, 5, 4, 3, 2, 1, or 0.
Answer:
g(4) = 157
Step-by-step explanation:
Substitute 4 for x in g(x) = 8x^2 + 9x – 7, obtaining:
g(4) = 8(4)^2 + 9(4) - 7 = 128 + 36 - 7 = 157
