An elliptical riding path is to be built on a rectangular piece of property as shown below.
Digiron [165]

The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1

a=10/2=5

b=8/2=4

put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1

Simplify and the answer is (x^2/16)+(y^2/25)=1

We are given arc KL is 12x+4, arc KJ is 8x-6, and angle E is 99 degrees. What is the actual degree measure of arc KJ? *
Svetlanka [38]

The  actual degree measure of arc KJ is 99 degrees

<h3>Circle geometry</h3>

From the given informtion

arc KL = 12x+4

arc KJ = 8x-6

<E = 99 degrees

The equation required to get the value of "x" is given as:

12x + 4 + 8x - 6 + 99 = 360

20x + 97 = 360

20x = 360 - 97

20x = 263

x = 13.15

For the arcKL

arcKJ = 8(13.15) -  6

arcKJ = 99degrees

HEnce the  actual degree measure of arc KJ is 99 degrees

What is the slope of the line that passes through the points (0,5) and (10,-7)
aniked [119]

Answer:

<em>Given </em><em>points </em><em>are </em><em>(</em><em> </em><em>0</em><em> </em><em>,</em><em>5</em><em> </em><em>)</em><em> </em><em>and </em><em>(</em><em> </em><em>1</em><em>0</em><em> </em><em>,</em><em> </em><em>-</em><em>7</em><em>)</em>

Step-by-step explanation:

Slope ( m) = (y2 - y1) / ( x2 - x1 )

= (5+7)/(0-10)

= 12/-10

= -6/5
