Find an equation of the line passing through each of the following pairs of points.

Mathematics
1 answer:
Ksivusya [100]3 years ago
5 0
To find the equation of the line we will need to find slope and the y-intercept.
 
Given: (-3,9), (-3,-5)
 
What we know:
slope=m=(y2-y1)/(x2-x1)
           m=(-5-9)/9-3-(-3))=-14/0
           m=undefined

When slope=m is undefined we have an a line x=-3. That means that for every y the x value is always -3. This line x=-3 is a vertical line on the graph at -3.

the leaning tower of pisa in italy makes an angle of 86 degrees with the ground. a person standing on the ground approximately 8
Art [367]
See the picture to better understand the problem

we know that
in the triangle ABC
∠A+∠B+∠C=180°
∠C=180-(86+69)-----> ∠C=25°
Applying the law of sines
b/sin B=c/sin C------> b=c*sin B/sin C-----> b=82*sin 69/sin 25
b=181.14 ft

the answer is
181.14 ft

What is the area of the circle?
hodyreva [135]

Diameter = radius x 2

So, the radius is half of the denominator.

10 / 2 = 5

A = pi x r^2

A = pi x 5^2

A =  3 x 25

A = 75 ft^2

Hope this helps!

A segment with endpoints (5,8) and (-6,8) is rotated around the origin. How long will the new segment be?
Gekata [30.6K]
The segment was only rotated, not changed. It would be the same length as the original.

To find the length, use the distance formula.

\sqrt{ {(x2 - x1)}^{2}  + ( {y2 - y1)}^{2} }
(5, 8) would be point 1.

(-6,8) would be point 2.

Plug them into the formula.

\sqrt{( { - 6 - 5)}^{2}  + ( {8 - 8)}^{2}  }
Simplify.

\sqrt{( { - 11)}^{2}  + ( {0)}^{2} }
\sqrt{121 + 0}
\sqrt{121}
Square root this answer.
\sqrt{121}  =  + or - 11
Negative distances aren't possible, so your answer is 11.

Hope this helped!
