Two parallel chords of a circle, MN and PQ have lengths 12 cm and 16 cm. If the diameter of the circle is 20 cm, find the perpendicular distance between the chords. I am confused on how to do this, if I could get some help that would be very much appreciated!

You deposit $5000 each year into an account earning 3% interest compounded annually. how much will you have in the account in 30 years?

Acertain company's main source of income is a mobile app. the company's annual profit (in millions of dollars) as a function of the app's price (in dollars) is modeled by p(x)=-2(x-3)(x-11)p(x)=−2(x−3)(x−11 ) which app prices will result in \$0$0 annual profit? enter the lower price first.
