Answer:
Hello how are you lol
Step-by-step explanation:
All of those are true, except the one about the radius. Because alternate definition of diameter uses the idea of chord. So, both ends of a chord have to be on the circle, but one end of a radius is at the center, so a radius can't be a chord.
Account 1 = $5750 Interest 9% = $517.50
Account 2= $ 250 Interest 5% = $ 12.50
$517.50+$12.50=$350
