Which of the following is true of the constructions of an equilateral triangle, a square, and a regular hexagon when they are inscribed in circles? A. The diameter in the first step of the constructions divides each shape in half.

B. Three diameters are needed to construct each inscribed polygon.

C. The arc in step two of each construction divides the circle in half.

D. The line segments that form each shape are congruent to the diameter of the circle.

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

Consider the reaction 2x2y2+z2⇌2x2y2z which has a rate law of rate= k[x2y2][z2] select a possible mechanism for the reaction.

Ineed in figuring out this problem.
