Answer:
- 2
Step-by-step explanation:
f(2) = - 2
Answer:
18x² - 6x
Step-by-step explanation:
Differentiate using the product rule, that is
y = f(x)g(x), then
= f(x)g'(x) + g(x)f'(x)
here
f(x) = 3x² ⇒ f'(x) = 6x
g(x) = 2x - 1 ⇒ g'(x) = 2, thus
(3x²(2x - 1)
= 3x² × 2 + 6x(2x - 1)
= 6x² + 12x² - 6x
= 18x² - 6x
Answer:
4x^3y^2+4x^2y^2- 8xy^2
Step-by-step explanation:
Answer:
28π
Step-by-step explanation:
A =2πrh+2π
r= ft = 2
h= 5ft
A = 2π (2* 5 )+ 2π(2*2)
A= 2π (10)+2π (4)
A= 20π + 8π
= 28π
The correct answer is: 6.022x10²³
Actually, the more correct answer is its longer version: 6.022140857 × 10²³. Therefore, the correct Avogrado's number is equal to: 6.022x10²³. We use this to relate the molar mass of one substance to the mass of its sample.
