A sample of an unknown chemical element naturally loses its mass over time. The relationship between the elapsed time t, in days, since the mass of the sample was initially measured, and its mass, M(t) in grams, is modeled by the following function: M(t)=900⋅(827)^t Complete the following sentence about the rate of change of the sample. Round your answer to two decimal places. The sample loses 1/3 of its mass every days.

noncoplanar points are points that do not lie on the same line.

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
