Answer:
Remember, if H(x) and J(x) are functions, then . And G(x) is the inverse function of H(x) if
With . Since H and J are the same function, then
.
Since , then H and J are inverses.
When you divide 86 by 18 you get 4.7777777777777777777777777777777777777 so she could technically make 4 so <u>A</u><u />
4. The answer is -7 and 7. Start at 0 and count to the left. That’s -7. Then to the right it’s 7
Given equation:
P=1500 (1.04)^x
When have to find x, when population, p=1900
Put value of P=1900 in above equation.
1900=1500(1.04)^x
Divide both sides by 1500
19/15=(1.04)^x
1.27=(1.04)^x
Take natural log.
ln(1.27)= ln(1.04)^x
ln(1.27)=x ln (1.04)
Divide both sides by ln (1.04)
x=6 years
Answer: 6 years
