Find four geometric means between 25 and 800.

Actually, you have to find four missed terms of geometrical sequence. Denote

and r - ratio, then

.

Since , you have that , then

.

Now substitude r=2 in each of unknown 4 terms:

.

four geometric means between 25 and 800 are 50, 100, 200, 400.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
