Given:
[tex]g(x)=\sin(5x)\degree+7.5[/tex]
Where g(x) is the number of units of natural gas used.
x is the number of months.
Required:
To find the natural gas used bu Hall family in june.
Explanation:
When x = 6
[tex]\begin{gathered} g(6)=\sin(5\times6)+7.5 \\ =\sin30\degree+7.5 \\ =0.5+7.5 \\ =8 \end{gathered}[/tex]
8,000 natural gas used by the Hall family in June.
Final Answer:
The option K is correct.
8,000
