Mathematics
1 answer:
Paul [167]2 years ago
6 0

Answer:

101

Step-by-step explanation:

\log a=-8\\\\10^{\log a}=10^{-8}\\\\a=10^{-8}

\log b=-9\\\\10^{\log b}=10^{-9}\\\\b=10^{-9}

\log c=-9\\\\10^{\log c}=10^{-9}\\\\c=10^{-9}

\displaystyle \log\frac{a^2}{b^5c^8}=\log\frac{(10^{-8})^2}{(10^{-9})^5(10^{-9})^8}=\log\frac{10^{-16}}{(10^{-9})^{13}}=\log\frac{10^{-16}}{10^{-117}}=\log(10^{-16-(-117)})=\log(10^{101})=101

Please help thank you.

Hello!

To solve this we use the equation sin60 = (s/2) / (d/2)

s is a side of the triangle
d is the diameter

sin60 = s/d

\sqrt{3/4} =s/d

d=s/ \sqrt{3/4}

d = s \sqrt{4/3}

d = 2s/ \sqrt{3}

put 6 in for s

d=12/ \sqrt{3}

d =  \sqrt{48}

d = 6.9

The answer is C) 6.9

Hope this helps!
