Answer:
We can do 220 jumping jacks in 5 minutes.
Step-by-step explanation:
We are given the function:
[tex]j(x) =44x[/tex]
Note: Considering there is typing mistake and the function is: j(x)=4x
where x is minutes
We need to find How many jumping jacks can you do in 5 minutes.
So, here x=5
Now putting value of x in the given function
[tex]j(x) = 44x\\Put \ x=5\\j(5)=44(5)\\j(5)=220[/tex]
So, we can do 220 jumping jacks in 5 minutes.
