The HNH Corporation offers 4-year, 9 percent coupon bonds with annual payments and a yield to maturity of 7.8 percent. What is the market price of a $1,000 face value bond? (0.5 score)

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.

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.

i those same problems in math and dont know how to do them

they aren't great and cause destruction, idk man
