Its 7 hours and 15 minutes
Answer:
f(4) = 22
Step-by-step explanation:
I think that you type wrongly.
we have f(1) = -5
and f(n) = f(n-1) + 9
Find f(4)
Then
with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4
with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13
and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22
So f(4) = 22
Hope you understand.
Answer:
-1/9
Step-by-step explanation:
-7/9 + 2/3 also equals to 2/3 - 7/9
Now make the denominator same
LCM of 3 and 9 = 9
2/3 = 6/9
∴ 6/9 - 7/9 = -1/9
