What's is an equation of the line that passes through the point(-3,-1) and is perpendicular to the line x-2y=6

katrin2010 [14]

Answer:

$y+1=-2(x+3)$

Step-by-step explanation:

Slope is negative reciprocal when two lines are perpendicular

m1=1/2 therefore m2=-2

The equation of the line in point-slope form is given as

$y-y_1=m_2(x-x_1)$

Here m=-2 and (x1, y1)=(-3, -1)

Therefore,

$y+1=-2(x+3)$

Answer:

$AB=148.76\ m$

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

The triangle PAB is a right triangle because the sum of ∠APB and ∠PAB is equal to 90 degrees

In the right triangle PAB

$sin(\angle APB)=\frac{AB}{AP}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(25^o)=\frac{AB}{352}$

solve for AB

$AB=sin(25^o)(352)=148.76\ m$
