Answer:

y = -5x + 5

Step-by-step explanation:

Let the equation of the line be: y = ax + b.

The given points should satisfy the equation.

Substituting the points in the equation we get the values of 'a' and 'b'.

The first point is: (1,0)

⇒ 0 = a(1) + b ⇒ 0 = a + b

⇒ b = -a

(2, -5) is another point. Substituting this we have:

-5 = a(2) + b = 2a - a = a

⇒ a = -5

⇒ b = -a = 5.

Therefore, the equation of the line becomes y = -5x + 5.

two arcs of concentric circles are intercepted by the same central angle. the resulting arc length of the arc of the larger circ

Bond [772]

the complete question in the attached figure

Let
A°-----------> the same central angle

For the larger circle
length of larger circle=2*pi*r-------> 2*pi*12-----> 75.36 m

360° (full circle) has a length of------------> 75.36 m
A°-----------------------------------> 16 m
A°=(16)*360/75.36--------> A=76.43°

For the smaller circle
length of smaller circle=2pi*r-------> 2*pi*7.5-----> 47.1 m

360° (full circle) has a length of------------> 47.1 m
76.43°-----------------------------------> X
X=76.43*47.1/360-----> X=10 m ----> length arc of the smaller circle

the answer is
the length arc of the smaller circle is 10 m
