The radius of a circle is 15 inches. A chord is drawn 4 inches from the center of the circle. How long is the chord?
Alex73 [517]

Let X represent the length of the chord.

By using Pythagoras' Theorem:

4^2 + (X/2)^2 = 15^2

(X^2)/4 = 209

X^2 = 836

X = 28.91

  1. The equilibrium price is $1.12.
  2. If price is $0.98, there would be scarcity of Super Widgets.
  3. When price is $0.98, quantity demanded is y.
  4. When price is $0.98, quantity supplied is x.
  5. When price is $1.22, there would be a surplus of Super Widgets.

<h3>What is equilibrium? </h3>

Equilibrium price is the price at which the quantity demanded equals the quantity supplied. The equilibrium price is $1.12.

Above equilibrium price, quantity supplied would exceed quantity demanded and there would be a surplus. When price is below equilibrium price, quantity supplied would be less quantity demanded and there would be a scarcity.
