If cos(Θ) = -2 9 , and 90° < θ < 180°, what is the value of tan(θ)?
frosja888 [35]
We know that

if  <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative

sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9

tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2

the answer is the option
<span>A) -77sqroot/2</span>

Damm [24]

Complete question:

The line graph relating to the question was not attached. However, the line graph has can be found in the attachment below.

Answer:

17,209

Step-by-step explanation:

The line graph provides information about alcohol-related highway fatalities between year 2001 to 2010.

Determine the average number of alcohol-related fatalities from 2001 to 2006. Round to the nearest whole number.

The average number of alcohol related fatalities between 2001 - 2006 can be calculated thus :

From the graph:

Year - - - - - - - - - - Number of fatalities

2001 - - - - - - - - - - 17401

2002 - - - - - - - - -  17525

2003 - - - - - - - - -  17013

2004 - - - - - - - - - 16694

2005 - - - - - - - - - 16885

2006 - - - - - - - - - 17738

To get the average :

Sum of fatalities / number of years

(17401 + 17525 + 17013 + 16694 + 16885 + 17738) / 6

= 103256 / 6

= 17209.333

Average number of alcohol related fatalities is 17,209 (to the nearest whole number)

Inscribe a circle in a unit square and to r= 1000 random.
Oduvanchick [21]

Step-by-step explanation:

area of square = 1

area of a circle in square = \pi r^2 = \pi *(1/2)^2 = \frac{\pi }{4}

bu estimate  p^ = X/n = 760/1000 = 0.76Therefore, &#10;[tex]\frac{\pi }{4} \approx 0.76

\pi \approx 0.76*4 =3.04

b) if n tend to infinity

\pi will approach 3.14
