Question

What is the value of 1 over 2 x^3 + 3.4y when x = 3 and y = 4?

A. 15.85
B. 18.1
C. 27.1
D. 31.6

Answer 1

Answer:

67.6

Solving Steps:

=> 2x³ + 3.4y

=> 2(3)³ + 3.4(4)

=> 2(27) + 13.6

=> 54 + 13.6

=> 67.6

Answer 2

Hey there!

1/2x^3 + 3.4y

= 1/2(3)^3 + 3.4(4)

= 1/2(3 * 3 * 3) + 3.4(4)

= 1/2(9*3) + 3.4(4)

= 1/2(27) + 3.4(4)

= 27/2 + 3.4(4)

= 13.5 + 13.6
= 27.1

Therefore, your answer is: 27.1

Good luck on your assignment & enjoy your day!
