Answer:
A)2
Step-by-step explanation:
we would like to integrate the following definite Integral:

use constant integration rule which yields:

notice that we can rewrite √x using Law of exponent therefore we obtain:

once again use law of exponent which yields:

use exponent integration rule which yields;

simplify which yields:

recall fundamental theorem:

simplify:

hence
our answer is A
Answer:
-3r + 15 ---> answer
Step-by-step explanation:
r < 5
You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.
3r < 15
Now, subtract 15 from both sides, you will get this:
3r < 15
-15 -15
-------------
3r — 15 < 0
Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.
So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l
