Find the equation of the line through point (8,−9) ( 8 , − 9 ) and perpendicular to 3+8=4 3 x + 8 y = 4 .
Leno4ka [110]

The equation of the line will be 3y + 8x = 165.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

  • Find the equation of the line through point (8,−9) ( 8, − 9 ) and perpendicular to 3 x + 8 y = 4.

The given equation of the line is:-

3 x + 8 y = 4.

The slope of this line will be:-

3 x + 8 y = 4.

8y = -3x + 4

y = -3 /8x + ( 1 / 2)

y = mx + c

m = -3 / 8

Since the line is perpendicular to the other line 3x +8y = 4 so the slope will be inverse and negative for the line.

So the slope of the line will be -8 / 3

The equation of the line passing through the point will be given as:-

y - y 1 = m ( x- x1)

y - (-9) = ( -8 / 3) ( x - 8)

Y + 9 = ( -8 / 3 ) ( x -8 )

3 y = -8x + 165

3y + 8x = 165

Therefore the equation of the line will be 3y + 8x = 165.

Evaluate the expression. If necessary, round to the nearest hundredth. ln 0
STatiana [176]
Well, a logarithmic expression is just an exponential expression written from the point of the exponent.

now, ln is just a shorthand for the logarithm with a base "e" or euler's constant, so-called the "natural logarithm", now, let's use the exponential version of that here, and let's say equals an constant exponent of "k",

\bf \textit{exponential form of a logarithm}\\\\&#10;log_{{  a}}{{  b}}=y \implies {{  a}}^y={{  b}}\qquad\qquad &#10;%  exponential notation 2nd form&#10;{{  a}}^y={{  b}}\implies log_{{  a}}{{  b}}=y\\\\&#10;-------------------------------\\\\&#10;ln(0)=k\implies log_e(0)=k\implies e^k=0

now, look closely, what "k" value, what exponent, negative or fraction or positive, will ever make "e" to 0?  none, so one can say is "undefined".
