Answer:

Mercury

Step-by-step explanation:

We'll translate this into ratios.

First, V:E = 0.943:1

Then, M:E = 0.983:1

We already have their density in terms earth's density. They are in the same unit. So, we can compare them directly, with greater ratio means greater density. It's clear that Mercury has the greater density.

Hey can you please help me posted picture of question

Zinaida [17]

The inverse functions have a property that the composition of two inverse functions always results is x.

From the given options, only the pair given in option B result in the composition equal to x.

$F(x)= \frac{12}{x}-18 \\ \\ 
G(x)= \frac{12}{x+18} \\ \\ 
F(G(x))= \frac{12}{ \frac{12}{x+18} }-18 \\ \\ 
F(G(x))= \frac{12(x+18)}{12}-18 \\ \\ 
F(G(x))=x+18-18=x$

This proves, F(x) and G(x) are inverse of each other.

So the answer to this question is Option B

What is the value of X? round to the nearest hundredth

Oksi-84 [34.3K]

Using the law of Cosine:

Cos(angle) = Adjacent Leg / Hypotenuse

Cos(65) = x / 81.9

x = 81.9 x cos(65)

x = 34.61

The answer is A.
