Answer
V= Base x Height x Width
Step-by-step explanation:
2. f(x) = x - 2x² - 5 + 10x
=-2x² + 8x - 5
f'(x)= -4x + 8
4. y = 100(45x - 30 - 3x³ + 2x²)
= 100(-3x³ + 2x² + 45x -30)
= -300x³ + 200x² + 4500x - 3000
y' = -900x² + 400x + 4500
A.15 b.500 c.40 d.7.5 yeah, not to confident but I think it's correct.
The answer is C. Just divide all of the fractions and use the decimals to see which is bigger/smaller.
