Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
Then,
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
which yields
Answer:
636.17251
Step-by-step explanation:
V = πr^2h = π·4.5^2·10 ≈ 636.17251
$40 + $7.50x = 62.50 so what you do is take 62.50 - 40 = 22.50 and divide 22.50 by 7.50 which is 3 so 3 hours
X=1±i√19 is the answer -sorry if it looks confusing..-
