Answer:

The value of given expression is 27.1

C is correct

Explanation:

Given:
(1)/(2)x^3+3.4y

We are given an expression of two variable x and y.

We need to find the value of expression at x=3 and y=4

Put x=3 and y=4 into expression and simplify


\Rightarrow (1)/(2)\cdot 3^3+3.4* 4


\Rightarrow (1)/(2)\cdot 27+13.6


\Rightarrow (27)/(2)+13.6


\Rightarrow 13.5+13.6

Add both number


\Rightarrow 27.1

Hence, The value of given expression is 27.1
