70
Step-by-step explanation:
Answer: 
(x) = 
Step-by-step explanation:
f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes
y = 9x - 8 , then make x , the subject of the formula ,
9x = y + 8
x = 
Finally , replace x , with (x) and y with x , so we have
(x) =
Yes! 8 - 3 is 5
so it is A.
It is not multiplied or divided by one single number so the sequence is arithmetic not geometric
hope this helps!
Answer:
20cos(39) or 15.543 (3 d.p.)
Step-by-step explanation:
- Use SOHCAHTOA
- You want to find A and have an angle of 36° and H
- So use CAH
- cos(39) = x / 20
- x = 20cos(39)
