which of the following best explains how you would prove that the two functions, f(x)and g (x), are inverse of each other algebraically

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

elli's hot cocao is more chocolaty

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
