Answer:

x=4096, Option B

Step-by-step explanation:

Given, \log_{8}x=4

Formula needed,

\log_{a}b=\frac{\log b}{\log a}

Therefore,

\log_{8}x=\frac{\log x}{\log 8}

\frac{\log x}{\log 8}=4

{\log x}=4{\log 8}

\log x={\log 8^4}

x=8^4

x=4096

Option B is correct.

Answer:

Hope this helps :)

Step-by-step explanation:

8(x - 2) = 2x + 8

y+9 = -2(y + 1)

value of x in 8(x - 2) = 2x + 8

x=4

substitue

y+9=−2(y+1)

value of y y+9=−2(y+1)

Determine whether the two figures are similar. If so, give the similarity ratio of the smaller figure to the larger figure. The
zloy xaker [14]
We have that

smaller figure
ha=8.7
ra=1.6

larger figure
hb=10.44
rb=1.92

ha/hb=8.7/10.44----> 0.83
ra/rb=1.6/1.92-------> 0.83
ratio smaller figure to the larger figure
1.6/1.92-------> divided by 1.6 both members[1.6/1.6]/[1.92/1.6]-------> 1/1.2

the ratio ha/hb is equal to the ratio ra/rb
so
the smaller figure and the larger figure are similar
and
the ratio smaller figure to the larger figure is equal to---->  1/1.2

the answer is
the option yes 1/1.2
