Answer:

No, it's not

Step-by-step explanation:

A set is closed under a particular operation if the results of said operation still belong to the set.

So, this set is not closed under subtraction because if we take two of its elements, for example 5 and 8, the result of their subtraction 8-5=3 doesn't belong to the set.

Greg invested $9,000 in an investment account that earns 4.2% interest compounded monthly.
Ulleksa [173]

Answer:

Step-by-step explanation:

y=a(1+r/c)^{ct}\\ \\ y=9000(1+.042/12)^{12t}\\ \\ y=9000(1.0035)^{12t}\\ \\ a)\ y=9000(1.0035)^{12(10)}=\$ 13687.61\\ \\ b)\ 15400=9000(1.0035)^{12t}\\ \\ 1.0035^{12t}=77/45\\ \\ 12t ln(1.0035)=ln(77/45)\\ \\ t=(ln(77/45))/(12ln(1.0035))\\ \\ t\approx 12.8\ years
