y = (9x) ^ (1/3)

exchange x and y  then solve for y

x = (9y) ^ (1/3)

cube each side

x^3 = 9y

divide each side by 9

1/9 x^3 = y

the inverse function is 1/9 x^3

Can you help me solve this please :/

Answer:

2√3

Step-by-step explanation:

In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6

x=6/√3

rationalize the denominator:

6√3/3

simlify

2√3

so the answer is the third one. 2√3

The manager of an art gallery wants to bring in a new exhibit that will appeal to her customers. Which surveying method is most
amid [387]

Answer:

C

Step-by-step explanation:

A doesn't make sense, because there are probably many people younger than 50.

Not B because that would be hard since there are probably not many people coming to the gallery by themselves.

Lastly,

Not D because that isn't very fair because since the women probably have different views than the men.

B makes the most sense because it does not rule anyone out and it lets everyone have an equal chance of being surveyed.
