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.

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
