The Sommers invested $5000 for three years at 6.5%. How much interest did the investment earn in three years? What was the total amount of the account after three years? PLZ SHOW HOW YOU SLOVED IT! THX <3

$1039.74 and $6039.74

Step-by-step explanation:

Ok so if this is growing exponentially and is giving 6.5% per year then you would do (5000*0.065) + 5000 which is 5325 then you would do (for year 2). (5325*0.065) + 5325 which is 5671.125. And lastly, you would do (5671.125*0.065) + 5671.125 which is 6039.74 (rounded answer).

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.
