Question

If f(x)= 10 sin(x) – 3 then f (30%) = ?

A) - square root 3/2 -3
B.) 2
C.) -5/2
D.) 4/3 - square root 3/2

Answer 1

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

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* (1)/(2)-3\\\\=5-3\\\\=2`

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