If f(x)= 10 sin(x) – 3 then f (30%) = ?
marissa [1.9K]

Answer:

The value of f(30) is equal to 2.

Step-by-step explanation:

The given expression is :

f(x)= 10 \sin(x) - 3

We need to find the value of f(30)

Put x = 30 in above expression.

So,

f(x)= 10 \sin(30) - 3\\\\=10\times \dfrac{1}{2}-3\\\\=5-3\\\\=2

Hence, the value of f(30) is equal to 2.
