Step-by-step explanation:
You have to use logarithms.
1) a = log_3 (1/27) = -log_3 (27) = -3
2) b = log_3 (9 * 3^(1/2)) = log_3 (3 ^ {5/2}) = 5/2
3) c = -log_3 (sqrt3) = -1/2
A scale factor of 2 means the dimensions are multiplied by 2.
15 x 2 = 30
8 x 2 = 16
Answer:
8
Step-by-step explanation:
If you count up, 3 is 1 million and 8 is 10 million.
(1) -(5y - 2)= -5y+2
(2) -5 (3n + 1)= -15n - 5
(3) too long to do
