Answer:
Equation of the straight line passing through the point ( 1,2 ) and having the slope
x - √3y -1+2√3 =0
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the point (1,2) and an angle = ∝ = 30°
The slope of the line
m = tan 30°

<u><em>Step(ii)</em></u>:-
Equation of the straight line passing through the point ( 1,2 ) and having the slope

y - y₁ = m(x-x₁)
y - 2 =
( x -1)
√3(y-2) = (x-1)
⇒ √3y - 2√3 = x -1
x - √3y -1+2√3 =0
Answer:
The ratio is 3:8
Step-by-step explanation:
The circumference of a circle can be calculated using the formula;
C = 2 * pi * r
for 9 inches;
C = 2 * pi * 9 = 18 pi inches
For 24 inches;
C = 2 * pi * 24 = 24 pi inches
The ratio is thus;
18 pi : 48 pi
divide through by 6 pi
= 3: 8
