Hope this helps you. I apologize if it’s incorrect.
I believe the answer is 1.343 x 10^5
0
evaluate g(7) by substituting x = 7 into g(x
g(7) = (49-35-10)/2 = 4/2 = 2
now substitute x = 2 into f(x)
f(2) = √(4 - 48 + 144) = √0 = 0
(f ○ g)(7) = 0
The main formula we use here is Work=Rate*Time,
1. The rate (speed of working) of Dominik is

2. Let the the rate of Katarina be

Together they have a rate of

equal to

(project per hour)
so

simplify the units:



so the rate of Katarina is 3/40 (proj per hour)
Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)
In 5 hours Dominik complets 5*5/40=25/40 of the project
Katarina completes 5*3/40=15/40 of the project.
