I think this is.. ↓
grows 4% at every year
after 7 years ↓↓
4 × 7 = 28
A town has a population of 5000
28% of 5000 = 1400
5000 + 1400 = 6400
after 7 years, town has 6400 population = after 7 year grows 28%
Answer:
6
Step-by-step explanation:
f(6) from the graph is -6
g(5) from the graph is -5
4*f(6)-6*g(5)=(4)(-6)-(6)(-5)=-24+30=6
200,000 = 158,000(1.06)^x
Divide both sides by 158,000
1.2658 = 1.06^x
Take the log of both sides and use the power rule to bring down the exponent (x) to the front.
log 1.2658 = x log 1.06
Divide both sides by log 1.06
log (1.2658)/log(1.06) = x
x = 4 years
CHECK
y = 158,000(1.06)^4
y = 199,471.36
Answer:
Scale Factor: 15/3 = 5
y = 8 x 5 = 40
x = 38.5/7 = 7.7
Step-by-step explanation:
Scale Factor: 15/3 = 5
y = 8 x 5 = 40
x = 38.5/7 = 7.7
