6
Step-by-step explanation:
There are two ways you could do this. You could multiply the two numbers together and take the cube root of the result
Use y^x key or ^ key to find the answer.
216^0.33333333 = 6
or you could take the cube roots separately
And multiply those two results together
2 * 3 = 6

So, the function will be;
b.
Her friend Suzy has $161.00 in her bank account and is withdrawing $15 every week.
Using the same rule as in a above;
The function will be;
c.
The graph of the two functions is shown below;
d.
The point where the two lines intersect is shown in the graph above.
The point is at;
Which is at week 4 and balance $101.
e.
The point at which they intersect is the point where they both have the same values.
It is the week when both Sally and Suzy have the same amount in there account.
So, at the fourth week (week 4) Sally and Suzy both have $101 in their account
