A. x intercept is -8 ; y intercept is 4
Answer:
B. 8.
D. log2 256.
Step-by-step explanation:
Generally:
loga b + loga b
= loga b^2.
Therefore log2 16 + log2 16
= log2 16^2
= log2 256.
From the above:
256 = 2^x where x is the log.
Now 2^8 = 256 so the original log2 16 + log2 16 = 8.
We conduct long division, cancelling each term in x³ + 6x² + 3x + 1. As so:
x²(x -2) = x³ - 2x²
Subtracting from the original equation, we get:
8x² + 3x + 1
8x(x - 2) = 8x² - 16x
Subtracting from the new equation, we get:
21x + 1
21(x - 2) = 21x - 42
Subtracting from the new equation, we get:
43
The answer is x² + 8x + 21 with a remainder of 43.
