Jobie starts with $325 in her piggy bank. each month she adds $10. which recursive function rule models the total amount in jobie’s piggy bank at the end of each month? an=10⋅an−1 and a1=325 an=10+an−1 and a1=325 an=325⋅an−1 and a1=10 an=325+an−1 and a1=10

A recursive formula represent the nth terms of a sequence in terms of it's previous (n-1)th term and it include first term.

Let's assume,

= First term,

= nth term,

= Previous term of nth term or (n-1) the term.

According to the problem,

Jobie starts with $325 in her piggy bank. Each month she adds $10.

Which means first term:

Since he is adding $10 each month. So, this month if he will have then in the next month he will have .

So, the recursive formula will be ,

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
