Consider the following class declaration: class thing { private: int x; int y; static int z; public: thing() { x = y = z; } static void putthing(int a) { z = a; } }; int thing: : z = 0: assume a program containing the class declaration defines three thing objects with the following statement: thing one, two, three; a) how many separate instances of the x member exist? b) how many separate instances of the y member exist? c) how many separate instances of the z member exist? d) what value will be stored in the x and y members of each object?

3 instances of x member

3 instance of y member

3 instance of z member

Thing :: putThing(2)

Step-by-step explanation:

a) How many separate instances of y member

there are 3 instance of y member

b) How many separate instances of x member

there are 3 instance of x member

c) how many separate instance of the z member

there are 1 instance of  z

Statement Call put thing member function we get

Thing :: put thing()

180

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
