Answer:

-57

Step-by-step explanation:

log \frac{ {c}^{7} }{ {a}^{6} {b}^{2}  }  \\  \\  = log {c}^{7}   - log( {a}^{6} {b}^{2} )  \\  \\  = log {c}^{7}   - (log {a}^{6} +  log{b}^{2} )\\  \\  = 7 \: log {c}   - (6 \: log {a}+  2 \: log{b})\\  \\  = 7 \:( - 9) - [6 \: ( - 5)+  2 \: (12)] \\  \\  =  - 63 - [ - 30 + 24] \\  \\  =  - 63 - [- 6] \\  \\  =  - 63 + 6 \\  \\  =  - 57

natali 33 [55]

Answer:

Her score in the first game was 173.

Step-by-step explanation:

Sue's total score for the 3 games = 3*162 = 486 points.

Let her score in the first game be x points. Then in the second game she scored (x - 10)  and in the third, ( x - 10 - 13) points:

x + (x - 10) + (x - 23) = 486

3x - 33 = 486

3x = 519

x = 173 (answer).

Serhud [2]

The cost of extracting the first 50 tons of copper is $151,000.

Step-by-step explanation:

Start-up costs of $150,000.

For the 50 tons of cooper.

C(x) = 0.6 + 0.008x

So

C(50) = 0.6 + 0.008*50 = 1

1 thousand dollars.

So

$150,000 + $1,000 = $151,000

The cost of extracting the first 50 tons of copper is $151,000.
