A person has body fat percentage of 17.2% and weighs 171 pound how many pounds of her weight is made up of fat
Citrus2011 [14]

Answer: 29.41 pounds

Step-by-step explanation:

You have the following information given in the problem:

- The fat percentage that the person has is 17.2%

- The person weighs 171 pounds.

Therefore, to calculate the amount of pounds of her weight is made up of fat (which you can call x), you must multiply the weight of the person by the fat percentage.

Therefore, you obtain the following result:

x=171lb*0.172\\x=29.41lb

Find the interval(s) over which the function is decreasing
son4ous [18]

Answer : (0,3) U  (3, ∞)

We need to find  the interval(s) over which the function is decreasing

We look at the intervals of x  where the graph is decreasing

Decreasing interval of the graph is the part where the graph goes down

We look at the part where the graph changes direction

In the middle  inverted U shaped graph , the graph changes direction and start decreasing at x=0

the graph is decreasing till x=3

so first decreasing interval is x=0  to 3. we write it as (0,3)

After x=3 the graph starts decreasing and it goes to infinity

So the second decreasing interval is 3  to infinity . We write it as (3, ∞)

Now combine both intervals by a 'U' union

(0,3) U  (3, ∞)
