A² + b² = c²
a² = c² - b²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = √45
a ≈ 6.7082
a = 6.7
Answer:
I think it's -2
Step-by-step explanation:
F^1(-2) = 2(-2) = -4
f(-4) = 1/2 * -4 = -2
f(f^-1(x)) = x so answer is -2
Answer:
-8
Step-by-step explanation:
substitute x with 3
-4(3) + 4
simplify (multiply)
-12+4
simplify
-8
It isn't different, it is very much the same
1-1 = 0
.1-.1 = 0
5.25 - 3.75 = 1.50
1.0005 +1.005 = 2.0055
just make sure to line the decimal places on top of each other <span />
