Option B: 5 is the value of f(3)
Explanation:
The equation of the piecewise function is given by

We need to find the value of 
The value of the function f can be determined when
by identifying in which interval does the value of
lie in the piecewise function.
Thus,
lies in the interval
, the function f is given by

Substituting
in the function
, we get,


Thus, the value of
is 5.
Therefore, Option B is the correct answer.
Answer:
Yes
Step-by-step explanation:
You can check whether the ratios form a proportion, by setting one piece of the ratios as x
Thus, we can use the equation 4/3.2=22/x.
From this, we get 4x=70.4.
Solving for x gives us 17.6.
