A chemist has 50 grams of the isotope gold-196 which has a half-life of one week. This means that the amount of the sample decreases by half each week. Determine the equation and the graph of its solution set to represent the amount of gold-196 over the course of several weeks.

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

Which of the following will form the composite function?

Prove the converse of the pythagorean theorem using similar triangles. the converse of the pythagorean theorem states that when the sum of the squares of the lengths of the legs of the triangle equals the squares length of the hypotenuse, the triangle is a right triangle. be sure to create and name the appropriate geometric figures.
