It has 4 significant figures
the assumption here is that the function f(x), has an inverse function of f⁻¹(x), so let's assume that is indeed the case, f⁻¹(x) is the inverse function of f(x).
for functions and their inverse, if they're indeed inverse of each other, then
f⁻¹( f(x) ) = x
f( f⁻¹(x) ) = x.
Answer:
The side length is approximately 11.3 inches
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
128 = s^2
Take the square root of each side
sqrt(128) = sqrt(s^2)
11.3137085= s
The side length is approximately 11.3 inches
The first one is 52/161. The second one is correct.
Answer:
x=1
Step-by-step explanation:
-31 - 4x= -5 - 5 (1+5x)
-31-4x=-5-5-25x
Separate the different variables and solve.
-31+5+5=4x-25x
-31+10=-21x
-21=-21x
x=1
