Answer:
The number of the students who got selected are 4,13,22,31.
Step-by-step explanation:
The professor wants to select 4 students randomly.
She randomly select the fourth and every ninth student after that
First the 4th student is selected
Now by using the next term formula which is
=>a + d(n-1)
The next student is the 2nd student.
=>4 + 9(2-1)
=>4 + 9(1)
=>4 + 9
=> 13
The 3rd student will be
=>4 + 9(3-1)
=>4 + 9(2)
=>4 + 18
=> 22
The 4th student will be
=>4 + 9(4-1)
=>4 + 9(3)
=> 4+ 27
=> 31

Answer:
Step-by-step explanation:
a. The vertex is (1, -9). False. The vertex is (-1, -9).
b. The graph opens upward. True. That coefficient '6' is positive.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units. False. It's DOWN 9 units.
d. The graph is steeper than the graph of f(x) = x^2. True. The given function increases 6 times faster than does x^2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Let's put f(x) = 6(x + 1)^2 -9 into standard form. Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9. YES, TRUE
