c220 jumping jacks
b. 239 jumping jacks
d 8jumping jacks

Answer 1

We can do 220 jumping jacks in 5 minutes.

Explanation:

We are given the function:

`j(x) =44x`

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

`j(x) = 44x\\Put \ x=5\\j(5)=44(5)\\j(5)=220`

So, we can do 220 jumping jacks in 5 minutes.
