Volgvan

Answer:

6.69 to the nearest hundredth

Step-by-step explanation:

Use the law of sines

Let x = PQ

$\frac{sin 72}{12} = \frac{sin 32}{x}$

x sin 72 = 12 sin 32

$x = \frac{12 sin 32}{sin 72}$

x = 6.69 to the nearest hundredth

Which of the following is equation of a line that passes through (-2,1) and (-4,-3)?

ladessa [460]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

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

We have the points (-2, 1) and (-4, -3). Substitute:

$m=\dfrac{-3-1}{-4-(-2)}=\dfrac{-4}{-2}=2$

$y=2x+b$

Put the coordinates of the point (-2, 1) to the equation:

$1=2(-2)+b$

$1=-4+b$ add 4 to both sides

$5=b\to b=5$

Finally:

$y=2x+5$
