In properties of logarithms, what is log2 25?
spayn [35]
log_a(b)=clog_a(b)=c translates to

a^c=ba^c=b
let's say it equals y

log_2(25)=ylog_2(25)=y
trsnaltes to
2^y=252^y=25
doesn't help us
we can also translate it to
log_2(5^2)log_2(5^2) or 2log_2(5)log_2(5^2)

Figures A and B at right are similar. Assuming that figure A is the original figure, find the scale factor and find the lengths
AnnZ [28]

The scale factor is: 1/5.

The missing sides of figure B are: 2.4, 3.6, and 4.

<h3>How to find Scale Factor?</h3>

Scale factor = dimension of new figure / dimension of original figure

The polygons given are shown in the diagram attached below.

Figure A is the original figure

Figure B is the new figure.

x, y, and z has been used to mark the missing sides of figure B.

One dimension of original figure = 15

Corresponding dimension of the new figure = 3

Scale factor = new/original = 3/15

Scale factor = 1/5

To find the missing sides of figure B, multiply each corresponding side lengths of Figure A by the scale factor:

x = 12 × 1/5 = 2.4

y = 18 × 1/5 = 3.6

z = 20 × 1/5 = 4

In summary:

The scale factor is: 1/5.

The missing sides of figure B are: 2.4, 3.6, and 4.
