Mary Borrowed $3,000 at the rate of 8% per annum interest is compounded annually calculate the total amount owed at end of the 2 years? ​

A=P×(1+r÷100)t

A=3000×108÷100×108÷100

A=17496÷2

A=3499.2

Step-by-step explanation:

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.
