PLEASE HELP ME I'LL MAKE YOU BRAINLIEST!!!! In 1972, federal vehicle emission standards 3.4 grams hydrocarbons released per mile
AURORKA [14]
<h3>Answer: Approximately -0.0742857 grams per year</h3>

======================================================

Work Shown:

x = year

y = amount of hydrocarbon emissions in grams, per mile driven

m = rate of change = slope

m = (y2 - y1)/(x2 - x1)

m = (0.8 - 3.4)/(2007 - 1972)

m = -2.6/35

m = -0.0742857 approximately

The approximate rate of change is about -0.0742857 grams per year. The negative rate of change indicates the per mile hydrocarbon amount has gone down by about 0.0742857 grams each year.

I need help solving for x: log x = 2.46 - 1.12 * log y
Mariulka [41]
\bf log_{{  a}}(xy)\implies log_{{  a}}(x)+log_{{  a}}(y)&#10;\\\\\\&#10;% Logarithm of exponentials&#10;log_{{  a}}\left( x^{{  b}} \right)\implies {{  b}}\cdot  log_{{  a}}(x)&#10;\\\\\\&#10;{{  a}}^{log_{{  a}}x}=x\impliedby \textit{log cancellation rule}\\\\&#10;-----------------------------\\\\

\bf log(x)=2.46-1.12log(y)\iff log_{10}(x)=2.46-1.12log_{10}(y)&#10;\\\\\\&#10;log_{10}(x)=2.46-log_{10}(y^{1.12})\implies log_{10}(x)+log_{10}(y^{1.12})=2.46&#10;\\\\\\&#10;log_{10}(x\cdot  y^{1.12})=2.46\implies 10^{\cfrac{}{}log_{10}(x\cdot  y^{1.12})}=10^{2.46}&#10;\\\\\\&#10;xy^{1.12}=10^{2.46}\implies \boxed{x=\cfrac{10^{2.46}}{y^{1.12}}}

The order of the numbers from the greatest to the least is

|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|

<h3>Magnitude of numbers</h3>

From the question, we are to order the given numbers from the greatest to the least in magnitude

The given numbers are

|-20|, |-4|, |-6|, |8|, |2 3/10|, |12.3|

Since the modulo sign is included, the <u>negative signs</u> do not take effect.

Hence, the order of the numbers from the greatest to the least is

|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|
