Answer:
g(1)=-12, g(n)=g(n-1)*1/6
Step-by-step explanation:
From the explicit formula -72 and ( <u>1/6</u> )^n-1
the first term of the sequence is -72 and the common ratio is 1/6.
So, we know that g(1), which is the first term, is -72
and that g(n)=g(n-1)*1/6 is the common ratio.
hope this helps :-)!
Answer:
Julian has <em>16 dimes</em> and <em>6 quarters</em>
Step-by-step explanation:
Let's suppose Julian has q quarters and d dimes
The total coins are 22, that is
q+d=22
q=22-d [1]
The total amount of money he has is 310 cents which are made of 10d dimes and 25q quarters
10d+25q=310
Simplifying by 5
2d+5q=62
Using the relation [1]
2d+5(22-d)=62
2d+110-5d=62
3d=48 => d=16
q=22-16 = 6
So Julian has 16 dimes and 6 quarters
