Answer:
the slope of the line is y=5/3 x
Step-by-step explanation:
The perpendicular distance between the chord and the center of the circle forms a right triangle with the chord and the radius. Using trig:
sin 30° = x / (D/2)
sin 30° = 2x / D
1/2 = 2x / D
x = D/4
Answer:
1/6
Step-by-step explanation:
determine the difference between both of the x and y points. Ex: (x1, y1) (x2, y2) x2-x1= x3 and y2-y1= y3 so the slope would be y3/x3
8. $16.00
9.a. 9 mi
9.b. 5 inches
Answer:
Assuming the triangle is an equilateral triangle (all sides and angles are equal), <u>the equation 3x = 20</u> would be used to find the length of each side.
Step-by-step explanation:
Formula for perimeter of triangle:
P = a + b + c
where a, b and c are the sides of the triangle.
Assuming the triangle is equilateral, all sides would be equal,
a = b = c = x
⇒ P = x + x + x
<u>∴ 20 = 3x.</u>
