The initial number of atoms are 1,000 at t = 0. note t is dimensionless time. use t = 0.2 for finite difference method (fdm). (a) what is the number of atoms n(t), using analytic approach for 0 ≤ t ≤ 10? (0.5 pt) (b) what is the number of atoms n(t), using fdm for 0 ≤ t ≤ 10? (1 pt) (c) what is the number of atoms n(t), using matlab/octave built-in function, "ode45" for 0 ≤ t ≤ 10? (1 pt) (d) plot the results of parts (a) to (c)

answer: this is not a question

step-by-step explanation: this is a answer

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.

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
