F(1) = 2
f(2) = 3f(1) = 3(2) = 6
f(3) = 3f(2) = 3(6) = 18 (A)
4 floors with 6 class rooms each = 6*4 = 24 total class rooms.
24 class rooms x 34 students in each one = 816 total students.

Because he was at $-1,000 and he deposited $100 a month that he earns from watching the dogs so it took him 10 months to realize that his bank account is now at $0
Given:
A line contains the points R(-1, 8), S(1, 4) and T(6, y).
To find:
The value of y.
Solution:
Three points are collinear if:

A line contains the points R(-1, 8), S(1, 4) and T(6, y). It means, these points are collinear.



Subtract 12 from both sides.

Divide both sides by 2.


Therefore, the value of y is -6.
Complementary angles add up to 90 so
angle + 47 = 90
angle = 90 - 47
angle = 43 so A
