I think you meant "y = 4 arccot (x)."

This is equivalent to:

y
---- = arccot x

Assume you are working with a standard deck of 52 cards. There are 13 cards (2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, and

NemiM [27]

Answer:

$P(9\cup queen)=\frac{2}{13}$

Step-by-step explanation:

Total number of cards $=52$

Total cards of $9$ $=4(1\ club,1\ diamond,1\ heart,1\ spades)$

Total cards of Queen $=4(1\ club,1\ diamond,1\ heart,1\ spades)$

Total number of elements in $9\cup Queen$ $=8$

$P(9\cup queen)=\frac{elements\ in\ 9\cup queen}{Total\ number\ of\ elements}\\\\P(9\cup queen)=\frac{8}{52}=\frac{2}{13}$

A line contains the points (1, –6) and (–2, 6). What is the slope of a line that is perpendicular to this line?

OlgaM077 [116]

First, find the slope of the line contains the points (1,-6) and (-2,6) using slope formula
m = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

plug in the numbers
m = $\dfrac{6-(-6)}{-2-1}$
m = $\dfrac{6+6}{-3}$
m = $\dfrac{12}{-3}$
m = -4

Second, determine the slope of perpendicular line
The slope of the perpendicular line is the opposite and reciprocal from the other line. Thus, the slope is $\dfrac{1}{4}$
