What is the frequency of the function f(x)? f (x) = 3 cos (tx) – 2 express the answer in fraction form.

Frequency =

Step-by-step explanation:

We are given the following function and we are to find its frequency:

We know that the standard form of cosine function is

where is the amplitude, while is the mid line.

Frequency is given by:

where is frequency and is the period.

Finding period by comparing the given function:

Substituting B to get:

So, Period = 2.

Since frequency is , therefore

Frequency =

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
