To find the value of the expression 10x^3 - 4x + 2.3 when x = 0.3, we substitute 0.3 for x and simplify:
10(0.3)^3 - 4(0.3) + 2.3 = 10(0.027) - 1.2 + 2.3 = 0.27 - 1.2 + 2.3 = 1.37
Therefore, the value of 10x^3 - 4x + 2.3 when x = 0.3 is 1.37.
Answer: C
10(0.3)^3 - 4(0.3) + 2.3 = 10(0.027) - 1.2 + 2.3 = 0.27 - 1.2 + 2.3 = 1.37
Therefore, the value of 10x^3 - 4x + 2.3 when x = 0.3 is 1.37.
Answer: C
