6. (MGSE9-12.F. LE.5) An element is decaying according to the model given by y(x) = where x is measured in days and y(x) is measured in grams. Explain the correct meaning of the
7 in this situation.
A. Initially, seven grams of the element were present at x = days.
B. The element is decaying at a rate of 7 grams/day.
C. After 7 days, there is 1/3 of the element remaining in grams.
D. As the days continue to increase, the amount of element left approaches 7 grams.

Match the term on the left with its image or description on the right. match term definition diameter a) circle a and a line segment connecting points b and c which are on the circle. circumference b) circle a and a line segment connecting points b and c which are on the circle. radius c) a piece of the circumference of a circle secant d) two circles that share the same center. concentric circles e) the distance around a circle arc f) a segment between two points on a circle that passes through its center

What is the distance between (–2 1/2,-3) and (1, –3)?

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°.
