its so easy if you need help

Answer 2

Answer:

$0\leq d\leq 7$

Step-by-step explanation:

$11.79=11(1.01^d)\\1.01^d=\frac{11.79}{11} \\1.01^d=1.0718\\ln(1.01^d)=ln(1.0718)\\d ln(1.01)=ln(1.0718)\\d=\frac{ln(1.0718)}{ln(1.01)} \\d=\frac{0.069}{0.0099} \\d=6.9696$

By rounding up.

d=7

Hence, the domain is

$0\leq d\leq 7$
