Line L passes through the points (0, --3) and (6,9).<br> (a) Find the equation of line L.
valentina_108 [34]

Step-by-step explanation:

Given points are :

(0,\:-3)=(x_1,\:y_1) \:\&\: (6,\:9)=(x_2 ,\:y_2)

Equation of line in two point form is given as:

\frac{y -y_1 }{y_1 -y_2 }  = \frac{x -x_1 }{x_1 -x_2 }  \\  \\  \therefore \frac{y -( - 3)}{ -3  -9 }  = \frac{x -0 }{0 -6 }  \\  \\  \therefore \frac{y  + 3}{ -12}  = \frac{x  }{ -6 }  \\  \\  \therefore \frac{y  + 3}{ 2}  = \frac{x  }{1}  \\  \\  \therefore  \: y + 3 = 2x \\  \\  \huge \red{ \boxed{\therefore  \: 2x - y - 3 = 0}} \\ is \: the \: required \: equation \: of \: line.

Find cot theta if csc theta = <br><br>sqrt17/4 and tan theta &gt;0.​
Lorico [155]

Answer:

tan \theta = 4

Step-by-step explanation:

We know that

cosec \theta = \frac{hypotenuse }{opposite }

Given :

cosec \theta =\frac{\sqrt{17}}{4}\\

So 4 is the opposite side of theta.

tan \theta = \frac{opposite}{adjacent}

We use the Pythagorean theorem to find for the adjacent side.

a = \sqrt{17 - 4^2} = \sqrt{17-16} = 1

Therefore, \ tan \theta = \frac{4}{1} = 4

The base of a circular fence with radius 10 m is given by x = 10cos(t), y = 10sin(t). the height of the fence at position (x, y)
Karo-lina-s [1.5K]
The average height of the fence is 2 m; its length is 20π m. So, its 2-sided area is
  A = 2*(2 m)*(20π m) = 80π m² ≈ 251 m²

At 1 L/(100 m²), it will take 2.51 L of paint to paint both sides.
