Our basis is the given ratio of 1:44. The actual rocket is obviously larger than the model rocket. Thus, it means that for every 44 ft of the actual rocket, the scale of the model rocket would be 1 ft. Through ratio and proportion, the solution is as follows:

1/44 = x/168
x = 3.818 ft

<em>The height of the model rocket, is approximately 3.8 ft.</em>

A cabbage palmetto has a height of 80 feet. what is the approximate height of the tree in meters?
frutty [35]
1 foot is about 0,3 meters.
If the height of the cabbage palmetto is 80 feet, it should be about 80*0,3 = 24 meters.

So a cabbage palmetto with 80 feet of height is about 24 meters.

Hope this helps! :)

8. A computer application generates a sequence of musical notes using the function f(n) 6(16)", where n is the
s2008m [1.1K]

Applying an exponential property, it is found that the function that will generate the same note sequence as function f(n) is given by:

B. H(n) = 6(2)^{4n}

<h3>What is function for the note sequence?</h3>

The function for the node sequence is defined by:

f(n) = 6(16)^n

A function that will the same note sequence as function f(n) has the same initial value of 6. Additionally, applying an exponential property, we have that:

H(n) = 6(2)^{4n} = 6(2^4)^n = 6(16)^n

Hence option B is correct.
