Answer:
(a) 320 cm²
(b) 75 cm³
Step-by-step explanation:
The scale factor from A to B is 8/4 = 2.
The scale factor of the areas is 2² = 4.
The scale factor of the volumes is 2³ = 8.
(a)
80 cm² * 4 = 320 cm²
(b)
600 cm / 8 = 75 cm³
Answer:
(x-2) (4x^2+1)
Step-by-step explanation:
4x^3-8x^2+ x-2
Factor 4x^2 out of the first group and 1 out of the second group
4x^2 (x-2) +1(x-2)
Factor out (x-2)
(x-2) (4x^2+1)
Answer:
hold on im trying to solve it
Step-by-step explanation:
V is the voltage or the potential difference between the plates, usually expressed in volts.
Infinite parallel plates have a uniform electric field between them.
So V = 245 (V/m) * 0.0037 (m) = 0.9065 volts
