Find a recurrence relation for the amount of money in a savings account after n years if the interest rate is 6 percent and $50 is added at the start of each year.

Step-by-step explanation:

Suppose, is initial amount in the saving account,

Here, the annual interest rate is 6% and additional amount in each year is $ 50,

So, the amount after one year,

Amount after 2 years,

Amount after 3 years,

................................., so on....

Hence, by following the pattern,

The amount after n years,

Which is the required recurrence relation for the amount of money in a savings account

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
