The period in which a sample decays to one-half of its initial amount is called its half-life. The initial amount of iodine-131 in 14mg. The equation y 14() models this decay. If y
represents the amount remaining after t half-lives, which graph represents this situation?

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

The measure of an angle is 117°. what is the measure of a supplementary angle?
